1. Introduction 1.1. Program objectives

At present, development of IT research infrastructure in our country is at the level of Western European countries and its compliance was confirmed during cooperation with European scientific and academic network TEN-155. The idea of the program is to develop more advanced infrastructure together with widely accessible, advanced tools, services and applications for scientific environment as well as for government and self-government administration and the society. Usefulness of this infrastructure will be documented and reviewed through pilot implementations of selected applications. It is proposed that this vision is realized in the form of a program called:
 
 

PIONIEER:
Polish Optical Internet
- Advanced Applications, Services and Technologies
for Information Society
The program concept envisages realization of three basic objectives:
  1. Develop information sciences infrastructure in Poland up to the level, which facilitates conducting research in the area of challenges of contemporary science, technology, services and applications.
  2. Produce and test pilot services and applications for information society, which form the basis for implementations in sciences, education, administration and economy.
  3. Let Poland compete in the area of software development for new applications.
Developed, produced and implemented applications, services and technologies will be implemented in all areas of life. Therefore, during realization of the program, costs of implementations will be incurred by interested entities (ministriesgovernment, telecommunication operators, firms producing hardware and softwarevendors as well as other entrepreneurs).

As a result of program realization, also important detailed objectives will be achieved. The most important include:

1.2. Forms of program realization

Program objectives will be followed by consortia composed of scientific institutions, economic entities, government and self-government administration bodies, assuming that they will participate in financing of the aforementioned objectives realization.

Estimated expenditure required for program realization are presented in table 1.

The State Committee for Scientific Research (KBN) will subsidize the realization of program objectives Scientific Research Committee (KBN) will subsidize the realization of program objectives, using the existing principles and methods of funds allocation:

· applications (apart from applications in the area of computational sciences) will be subsidized in the form of specific projects or specific requested projects,

· applications in the area of computational sciences) will be subsidized in the form of proprietary research projects or research projects requested by KBN,

· network services can be subsidized in the form of specific projects or specific requested projects,

· network infrastructure and specialized infrastructure will be subsidized in form of specific projects, specific requested projects or investments made as joint ventures,

· international connections with scientific research networks (with network TEN–155 or with a designed GÉANT network, i.e. appropriated to be used exclusively for scientific purposes) - in form subsidies for special projects or research equipment SPUB.
 
 

Decisions on selection of applications, i.e. specific scope proposals, realization methods, financial impact as well as initiators and contractors of individual projects will be made on the basis of competition of applications. As far as possible, a principle of parallel objectives realization will be adopted, while ensuring a balanced regions’ development. The program will not breach the existing principles of IT infrastructure utilization by the scientific environmentcommunity. A separate body will be established for supervising the program realization. The supervision body will be composed of selected representatives of investors and economic entities working on specific projects.

Specific projects include research and development works, important for social and economic reasons, conducted at the request of economic entities, government administration or local self-government bodies. Application for subsidizing a specific project can be filed by a business entity operating in Poland, a company with a foreign shareholding implementing technological and organizational solutions, created as a result of domesticnational scientific research or research and development works, a scientific or research and development unit with its own experimental plant, a supreme or central government administration body, a province governor or local self-government body. An applicant for project subsidy, hereinafter referred to as “initiator” is responsible for project realization and utilization of produced outcome. Initiator indicates a contractor to perform research and development works, which may be a scientific institution, a research and development unit or other organizational unit conducting operations which are considered by appropriate KBN committee team to be scientific operations, research and development operations or innovative operations in the area of sciences and technology. Within a specific project, KBN may subsidize up to 50% (and in some exceptionally warranted cases up to 70%) of planned expenditure for research and development works, which may include applied research, the results of which are necessary for addressing practical issues as well as development works, conducted with a view to utilizing the results of that research (development of new or modernized materials, equipment, processes or technological methods, producing construction or technological documentation, making experimental installation or producing a prototype of a newly designed product or other equipment, conducting tests and examinations with the use of an installation or a prototype or a new technology developed in line with prepared documentation, making assessment of usability of a new product and its technical and utilization characteristics). KBN does not subsidize implementation-investment works through the project.

Specific requested projects include research and development works, important for social and economic reasons, conducted at the request of government administration bodies. An application for starting a requested specific project can be submitted by a supreme or central government administration body, a province governor or a province governor after receiving an opinion from a supreme government administration body responsible for subject of the project. Applicant is responsible for utilization of project outcome. Initiator or co-initiators are appointed as a result of an open tender, which is announced in “Rzeczpospolita” daily newspaper. Tender submissions can be filed by managers of scientific units or research and development units together with managers of a research team as well as managers of entities conducting documented operations in the area of scientific research or research and development works. Just like in the case of a specific project, within a requested specific project, KBN may subsidize applied research, the results of which are necessary for addressing practical issues as well as development works, conducted with a view to utilizing the results of that research. Implementation-investment works related with introduction of outcome of research and development works to social or economic practice cannot be subsidized by KBN.
 

 
2. Advanced network applications

Within the program, the following areas will be followed, in which application development projects will be realized:

A competition will be announced for making the above list more precise. Developed applications will include, in particular: Where possible, applications will be available in the form of portals, i.e. integrated access to various services with a joint context.
 
  2.1. Communication applications Communication applications will provide interpersonal communication services of new generation, based on utilization of voice and video transmission for scientific environment. Communication application should meet the following assumptions:
Within the application, there should be a set of communication solutions developed and implemented, which would also be available to mobile users, which would have, among others, the following functionality: Access to an ‘integrated science communication system’ will be provided Through through theis portal., access to an ‘integrated science communication system’ will be provided The system will be integrating integrate various networkings techniques of undercoat networks for voice and video transmissions.

Within advanced network services, voice and video transmission will be provided and managed with the use of networks based on the IP protocol. As far as voice transmission is concerned, the service will be integrated with a public telephone network (possibly with mobile telephony telephone networks) and the following functions will be made available:

The basic functions available in video transmissions will be the following: With regard to services in advanced network infrastructure, it is required that an undercoat network is provided with a group communication IP of a new generation and with a guaranteed band at request as well as implementation of different services function, called DiffServ.

Implementation of communication applications depends on developing adequate specialized infrastructure. It will consist of service access points established in urbanmetropolitan area networks computer networks, by way of installing a converter between a telephone network and and a package network (gateway and or gatekeeper,) "Voice over IP", "Video over IP" along with a steering module and a digital library server.
 
 

2.2. Computational sciences applications

Selected examples of computational research:

Access to computational network services will include such services as: The above tools are available in many different systems (e.g. Globus, Legion MOL, Unicore) developed all over the world and available in the Internetthe network. Regardless of the envisaged application of any of these systems in Poland, it will be required to develop the following tools: as well as specialized tools: The above network services systems require access to very fast networks and advanced specialized infrastructure, including, among others, high power computational systems and archiving systems. From today’s perspective, requirements with regard to a fast network can be determined at the level of 2.5 Gb/s, however in two, three years, it will be 10 Gb/s. Practical realization of these requirements, available operationally, is reflected in multi-channel DWDM networks with capacity of n x 2,5 Gb/s.

In terms of requirements for systems high computational power, it is necessary to provide access to country specific systems with a real computational power, which is maximum one grade lower than the existing world level, with the same technological solutions (differing only in scale). Absolute minimum of total computational power in HPC center, as at today, should be assumed at the level of 300 GFLOPS, with a balanced architecture.
 
 

2.3. Applications for supporting teaching with the Internet access

The role of applications for supporting teaching with the Internet access is to utilize vast information and illustration resources available on the Internet, with a view to supporting public education. It is required that topical thematic portals are created for teachers of individual subjects along with associated portals for sharing teaching materials, individual learning by way of accessing the same information at home as well as constant access to current data from different topical thematical issues.

Implementation of such system is conditioned by adequate tool software. The purpose of that software is to make available access interfaces to services provided for applications on the basis of information available on the Internet.

Selected specialized tool software includes:

Apart from access to advanced network infrastructure, access to a disperseddistributed domesticnational archiving facility system may also be required.

Development of these applications assumes broad access of schools to the Internet. In order to facilitate realization of this idea, it is necessary to make a pilot implementation of wireless transmission technology of a new generation (including satellite) as well as broad-bandbroadband transmission through copper links (xDSL type technologies) and television networks (through CATV cable modems).

That is how conditions will be created for the realization of a future program, which will facilitate connecting schools, depending on technical conditions, with channels of 2 Mb/s, 10 Mb/s, 100 Mb/s. Within realization of this application, one can also expect cooperation with other associated initiatives, e.g. Interkl@sa, Internet in each municipality.
 
 

2.4. Remote teaching applications

Remote teaching (and learning) applications are supposed to utilize modern computer techniques, communication techniques and tools for group work with a view to developing a disperseddistributed teaching system. These applications, in their target version, will cover a few areas of the training process: remote learning, interactive teaching - remote sessions, remote exercises.

The first of these levels is to make lectures and multimedia presentations stored in data bases available to group and individual recipients. These applications may be of an open nature (addressed to any recipient). Remote sessions can be conducted between a lecturer and students located in different points of the network. Software used should make it possible for recipients to ask questions to the lecturer. One could use video conferencing mechanisms in this respect. The third level, additionally covers a mechanism of student direct participation in laboratory tests in a disperseddistributed and/ or virtual laboratory. Besides, there is also a possibility of individual assessment of students’ knowledge level. Further development of such applications may lead to establishment of virtual classes. The success of the remote teaching program is conditioned on the development of a feedback loop, which would facilitate student interaction (regardless of the course level) with teachers.

In order to realize the aforementioned assumptions, one needs to make first installations of the first few points for asynchronous lecturing and finance the preparation of adequate contents. For the remaining modes, it is necessary to select, through a tender, several competence centers in respect of remote teaching, in which equipment will be installed for multimedia ‘live’ transmission. Properly equipped lecturing halls should immediately be organized in majority of centers.

Implementation of remote teaching application requires advanced tools, which include, e.g.:

Development of these applications envisages access to advanced network techniques and adequate specialized infrastructure. Within computer networks, it is necessary to implement digital transmission technology in IP networks (perhaps also ATM), communication transmission as well as Quality of Service mechanisms.

Broad implementation of applications in the above mentioned areas will be possible thanks to a national program, within which competence centers will be established to ensure organization of contents and specialized infrastructure. Eventually, it is envisaged that for the needs of this program a separate channel on urbanmetropolitan area networks and national network will be used with capacity of 2.5 Gb/s, which will then be made available in the form of virtual networks for specific courses.

It is also planned to introduce a system for processing examination data, which will facilitate making tests and exams within the education reform. This introduction requires efficient functioning of a broad access network.
 
 

2.5. Three-dimensionalGeographical information applications
 
 

Applications from the area of three-dimensionalgeographical information are supposed to make available an integrated system using geographic data in many user areas.

Pilot application may include two tasks:

    1. managing regional ???? geographical three-dimensional infrastructure, based on satellite data and/ or airborne,
    2. managing integrated regional infrastructure including the following networks: water distribution, heat distribution, power network, gas grid and telecommunication network.
Applications of the above type require tool software, which will ensure: The entire system will be based on advanced communication infrastructure and it requires specialized server infrastructure, disperseddistributed archiving systems, data bases.

Data will be stored and managed at the regional level. Therefore, it is planned to introduce a pilot system realization program in selected regions.
 
 

2.6. Environmental resources management Aapplications for managing environment resources

Environmental resources Applications applications for managing environment resources cover two management areas:

Due to complexity of models, number of entry data, requirement of real time simulation realization, adequately high level of graphical data presentation as well as the necessity of communicating information on the actual and forecasted situation – this application requires access to systems of advanced network computational services and data storage systems. Apart from using the advanced network infrastructure, this application also requires coexistence of adequate computational infrastructure, such as: computational HPC systems, computational clusters, archiving systems, data base systems, graphical visualization systems. Network infrastructure should also facilitate transmitting satellite photographs.

A necessary condition for adequate utilization of this application is near-real time simulation realization.
 
 

    2.7. Remote Telemedicine applicationss
Remote medicine applications are supposed to assists in development of IT environment supporting development of remote medical services for scientific and service-providing units. This application will ensure access to the latest medical achievements, remote patient supervision. It will also help establishing a virtual medical consultant, with a high quality sound and image transmission in a transmission band of 2.5Gb/s separated for that purpose.

The application should cover:

and provide services: as well as provide access to bases of: Realization of remote medicine application requires the following network services: A necessary condition for development of remote medicine application is to have available the following exemplary elements of specialized infrastructure: 2.8. Group Collaborative work applications

The purpose of a group work application is to deliver possibilities of sharing an advanced work environment by a disperseddistributed group of people – also mobile users. Target form of application is a system based on access interface (e.g. portal), through which a user gains access to application elements and can communicate with other group members.

Implementation of the group work application requires tool software, which includes, e.g.:

In order to implement group work application, one needs to have available appropriate communication infrastructure, mainly access networks. Wireless networks are extremely important in that respect, because they facilitate mobile users participation.

3. Advanced network services

Realization of the discussed, advanced applications requires developing advanced network services. These services can be used by many different applications (shared services).

Main requirements in respect of development of these services relate to:

Taking into account the need for applications referred to under it. 2 to have access to advanced network services, the following services systems need to be developed and implemented: as well as a number of shared tools, including, e.g., the following: Advanced network services will be developed by way of gradual implementation of virtual and augmented reality techniques. These techniques facilitate integration of three-dimensionalgeographical presentation and interaction techniques with communication services.
 
  3.1. Computational grid and data grid

Computational grid and data grid represent a complete, dedicated system, which can be accessed by network users.

There is a plan to implement the following tools supporting users/ application programmers:

The above tools will facilitate automation of disperseddistributed applications development process.

An independent tool related with space management of network computational-entry services system users is a Virtual User system. This system, based on any queuing system, facilitates streamlining policy for user accounts management across the entire country (between computer centers) and provides these users with a possibility of accounting for resources used.
 
 

3.2. Network services system of digital libraries

This system is a library of sources with multimedia objects (texts, video, sound, images) along with metadata describing them as well as a set of tools for introducing, updating and making data available through advanced network infrastructure.

Network services system of digital libraries represents a base for development of the aforementioned applications: remote teaching and three-dimensionalgeographical information. This is a ready product that can be used for developing many other applications, such as: virtual museums, electronic publishing, demand telematic services.
 
 

Development of the system may utilize commercially available data base systems and software for development of interface communication between the system elements of a digital library as well as user authorization systems and access to catalogue directory services based on the LDAP protocol.

Additional software is required by tools and mechanisms for a single library:

as well as for a disperseddistributed system of digital libraries: 3.3. Other shared tools

A group of advanced network services must have a set of tools ensuring service management within this group. This set is composed of the following modules:

Within multimedia sound and image transmission, a group of advanced network services will include basic communication software for management and transmission: Development direction for advanced network services will be gradual implementation of virtual reality techniques. These techniques facilitate integration of three-dimensionalgeographical presentation and interaction techniques with communication services.

3.4. Specialized tools of advanced network services

Specialized tools of advanced network services are connected with specific applications. These tools are:

    1. communication application tools,
    2. computational sciences application tools,
    3. teaching support with the Internet access application tools,
    4. tools for remote teaching application and examination data processing system,
    5. three-dimensionalgeographical information application tools,
    6. group work application tools.
3.5. Software for producing services and tools

Development of necessary services and preparation of tools may require access to pre-defined program environments, data bases, etc. A lot of these tools are already available to scientific environment (existing licenses or free of charge access). Another lot will require to be purchased, licensed, etc. Besides, new types and generations of tools are to be established. This is also relating to applications.
 
 

4. Advanced network infrastructure

Advanced applications and advanced network services, required by these applications can only be developed in network infrastructure environment of a new generation, referred to as advanced network infrastructure. This infrastructure is developed so that advanced network services systems could operate in a dynamically defined network structure, up to the level of physical network. It is also necessary to reach transmission scalability of commonly generated broad-bandbroadband traffic.

The above requirements can be met by way of constructing an optical network in DWDM technology based on leased light pipes, light pipes acquired from domesticnational operators or proprietary light pipes installed by public roads. Optical network can integrate different types of transmissions, from ATM and POS to ‘clear’ pure’ IP network.

This should be an IP network at the technical level meeting the requirements of the latest world-wide solutions sufficient in a 2-3 years perspective, which will facilitate using ‘lambda router IP’ equipment and new protocols (e.g. MPl S). Access points to this network at its contacts with MANs will also ensure connections between individual lambda routers, connections with regional networks and gates to commercial telecommunication operators. Therefore, access point to such network will aggregate and offer a wide variety of interfaces, from 100 (34) Mb/s to 10 Gb/s (drawing Figure 4.1).

This infrastructure, apart from meeting the requirements described in this application report (2.5 Gb/s for domesticnational metacomputer and data storage system; 2.5 Gb/s for remote teaching system and broad Internet access; 1Gb/s for domesticnational PC systems cluster for disperseddistributed simulation applications), can additionally service specific area or governmental networks, e.g. 2.5 Gb/s for State administration.

One of the most popular transmission modules for optical networks is 10 Gb/s (4 x 2.5 Gb/s) while maximum capacity offered by currently available modules is at the level of 400 Gb/s.

Construction of a domesticnational optical network, preceded with technical tests in 2000, will be started in 2001 and completed in 2004. Topological structure of this network includes MAN network connections (drawing Figure 4.2). This spine will be gradually expanded by other regional networks in selected technology with capacity of up to 2.5 Gb/s. Within the existing infrastructure, adequate separated/virtual may be created – topical or governmental. Eventually, this network will cover all cities with scientific units’ networks and networks of colleges as well as other towns which used to be centers of ex-provinces, in which higher education colleges are established. Networks and hubs in these towns will be connected with regional access networks, which will facilitate developing a national network infrastructure.

It is envisaged that the construction of a domesticnational optical network will be progressed in line with the following schedule:

1. introductory stage: 2000: preparation of assumptions,

2. stage I: 2001 – 2002

- phase 1: 2001 a) development of operational pilot WDM network on light pipes or ‘lambda’ pipes acquired from telecommunication operators and purchase of equipment for optical network,

b) technical project, construction tender,

- phase 2: 2002 a) development of stage I light pipe infrastructure,

b) utilization of operational pilot network,

3. stage II: 2003 –2004 - phase 3: 2003 a) moving and installation of pilot network equipment in stage I light pipe infrastructure,

b) development of stage II light pipe infrastructure,

c) providing supplementary equipment,

- phase 4: 2004 a) installation of equipment in stage II light pipe infrastructure,

b) optical network acceptance and full utilization.
 
 

Construction of new generation regional networks is planned in the period of project’s stage II realization. Within stage III, implementations are planned as well as copying along with construction of regional access networks. Implementation consortia, operating since stage II of the project, should include regional operators, who will be implementing individual solutions and who should define pilot implementations.

UrbanMetropolitan area networks will be developing towards disperseddistributed service sharing points and disperseddistributed points for producing advanced network services. This will consist in implementation of optical technology, fast ATM network and/ or Gigabit Ethernet.

The aforementioned development must be accompanied by construction of local access networks in scientific units involved in the realization of this program. These networks should be scalable and with large capacity (ATM, Gigabit Ethernet) so that it could be possible to deliver dedicated channels (10 Mb/s, 100 Mb/s or even 1 Gb/s) to the end user producing applications or services. At the same time, local networks should ensure free Internet access is provided to all employees and students in line with existing principles.

Common access of scientific environment, also at home, to the developed structure will be pilot tested and launched by way of development of access networks in the following four technologies:

  1. xDSL,
  2. CATV network,
  3. wireless networks (GPRS and third generation GSM – UMTS, local wireless networks),
  4. satellite network.
Pilot access networks in each of these technologies, will be repopulated in at least three regions of the country and will service users from scientific environment. Pilot networks will be developed in cooperation with selected telecommunication operators.
 
5. Advanced specialized infrastructure In order to develop the required advanced network services and advanced applications, the advanced network infrastructure needs to be additionally provided with specialized infrastructure, such as: In the realization of the program, also specialized network systems will be required, connected with advanced research of techniques and advanced network services.
 

5.1. HPC systems

Conducted research and development of computational sciences applications require HPC centers to be further developed and mutually connected with a very fast computer network. Therefore, it is necessary that computational power is increased in national HPC centers and alternative cluster computational structure is developed.

HPC centers should have computational power of minimum 300 GFLOPS. All high power computational systems in these centers should have environment-nationwide nature.
 
 

5.2. Archiving systems

An important element of an advanced IT infrastructure, conditioning a possibility of realization of advanced applications and network services, is a data archiving option. Therefore, it is necessary to install, across the country, a warranted number of archiving systems with an adequate capacity. Annual capacity growth will be ca 25%. Archiving systems will be linked in a national structure with adequate advanced network services software, ensuring centralized management and user access.
 
 

5.3. Servers of multimedia data bases (digital libraries)

Development of advanced applications requires access to reliable and effective digital library servers. Therefore, it is necessary to install such servers in at least 10 MAN centers.

A server should have a multiprocessor or cluster architecture, effective external memory system in matrix scheme with capacity of at least several hundred GB, operating memory over 4 GB.

5.4. Remote teaching systems

Development of remote teaching applications requires at least a few centers in the country to be provided with remote teaching systems, including: remote teaching studios and remote teaching rooms.

Equipment for such studio is: For research and development purposes, at least one of those sets should ensure high definition TV technology (HDTV).

Another component of a remote teaching application is represented by auditorium remote teaching rooms.

Equipment for such rooms consists of: It is necessary to launch minimum several such rooms across the country, in particular in smaller college centers.
 
5.5. Communication servers  
For realization of communication services communication servers are required, which should be installed in all MAN centers. Configuration of such server will include a cluster of at least UNIX type systems, which will act as a server in the domesticnational network and a local server, respectively (for MAN network).
 
 
Configuration of such server includes: 5.6. Specialized networks  
Intensively utilized research area will be wireless broad-bandbroadband network systems and multimedia mobile terminals. At least one pilot installation of such network will be created in order to facilitate works on applications for it.
 
 
6. International network connections Period for realization of the presented program will be, at the same time, a preparatory period for Poland’s accession to the European Union. Therefore, a particularly important issue will be our country’s participation in all ‘Union’ initiatives. Cooperation of the Polish scientific environment in development of joint European science IT infrastructure is even now a good example of such initiatives.

Therefore, the priority is involvement of domesticnational academic broad-bandbroadband network POL-34 in creation and development of GÉANT project, successor of TEN-155 network. In this area, particularly important is the period of establishing concept assumptions for GÉANT network and then developing a technical concept. During these phases, decisions are taken with regard to network topology, distribution of its framing hubs, access hubs, shared connections structure, etc., as well as agreeing lists of these infrastructure elements, which will be jointly financed or subsidized with the funds of the 5th Frameworking Program.

The most important issue is to increase capacity of a communication channel between POL-34 network and TEN-155 network, as early as in the beginning of 2000, to the sufficient level in terms of transmission needs and adequately to the scientific environment level. Adequate benchmark is assumed to be parallel connections, which currently exist in academic networks in the Czech Republic and Hungary. Besides, realization of the PIONIEER program requires broad cooperation with teams in the USA, which are working on the Internet2 program and in Canada, where an optical network is being developed called CA*net3.

Therefore, it is necessary to:

- introduce connection with Europe (i.e. TEN-155 network) at the level of 155 Mb/s, increased at the time of establishing European multi-gigabit network (GÉANT program) to the level from 622 Mb/s to 2.5 Gb/s,

- create an access hub in Poland for connecting Eastern European countries with the GÉANT network,

- develop through connections to 2-3 identical European access hubs with a view to increasing reliability of a domesticnational network and mutual reinforcing of neighboring academic networks,

- connect Polish optical network with scientific optical network in Germany,

- introduce direct connections with the following networks: vBNS+, Abilene, CA*net3.
 
 

Connection with the USA networks, in the introductory phase, should include two separate links with the capacity of 45 Mb/s each, to a light pipe hub STARTAP of scientific networks located in Chicago, one of which would be dedicated mainly to cooperation with vBNS network and the other to ABILENE network. These connections should operate independently from the Internet channel for scientific traffic, also with capacity of 45 Mb/s. Within the realized program, it is also planned to introduce separate connection with a light pipe network CA*net3, with a capacity of 45 Mb/s. Connections with the American continent can be established together with DANTE consortium, through one of European countries, which have a direct connection; or independently through one of world operators.

In terms of cooperation with European networks, Poland should become a strong center of European scientific network, intermediating in traffic transmission of scientific networks of Eastern European countries.

It is also warranted to connect Polish optical Internet with one of European-wide optical networks as well as world-wide ones (e.g. HERMES, Oxygen2). Thanks to such multiple connections, Polish optical Internet, being a nationwide infrastructure, will become an integral part of the world system.
