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:
Polish Optical Internet
- Advanced Applications, Services and Technologies
for Information Society
The program concept envisages realization of three basic objectives:
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).
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.
Produce and test pilot services and applications for information society,
which form the basis for implementations in sciences, education, administration
Let Poland compete in the area of software development for new applications.
As a result of program realization, also important detailed objectives
will be achieved. The most important include:
1.2. Forms of program realization
producing concepts of organization-technical strategies for development
of information society by way of:
ensuring wide access to the Internet and its services for education sector,
creating a domesticnational infrastructure of a broad-bandbroadband government
and self-government administration network,
promoting new models of operation and cooperation between government, self-government
and economic institutions in a modern information society through advanced
services and applications,
showing a development path for the Polish IT business with regard to the
program products and commercial services for information society,
providing scientific environment with access to advanced network infrastructure
and specialized infrastructure (including computers with large computational
enabling Polish teams partnership participation in the 5th and
the 6th Framing Framework Programs and other international programs,
maintaining the level of technical and scientific IT infrastructure development
at the level of European Union countries.
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
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
· applications in the area of computational sciences) will be subsidized
in the form of proprietary research projects or research projects requested
· 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.

networks) and the following functions will be made available:
The basic functions available in video transmissions will be the following:
listening to sound materials (real time and off-line).
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.
transmitting static pictures and multimedia documents,

and or gatekeeper,) "Voice over IP", "Video over IP" along with a steering
module and a digital library server.
Computational sciences applications
Selected examples of computational research:
Access to computational network services will include such services
extracting and using genetic and molecular information,
biological information technology and genomics,
new diagnostic solutions, supporting therapy design and optimization,
examining the nature of physiological processes and controlled influence
disperseddistributed knowledge systems and digital archives, remote medicine,
material designing, new grades of materials (e.g. alloys, composites, high-molecular
systems with non-aliphatic structure, amorphous systems),
new processor technologies (also connected with alternative information
new technologies for protecting resources (deposits, yards),
disperseddistributed monitoring systems and systems warning about environmental
new, environment-friendly sources of energy,
Computational sciences, including i.e. computational chemistry and computational
modeling structure of physical-chemical systems
modeling dynamics of physical and chemical processes
molecular and neural computing
Information processing and transmitting techniques
examining process dynamics in large networks, their optimization and steering
integration of modeling algorithms and information extracting, with broad
utilization of visual solutions.
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:
tools (in the form of API – Application Programming Interface) ensuring
security of access to applications and the entire system,
information tools (API forto maintenance and information services) – information
on the status of individual computational systems potentially assigned
communication tools and libraries (in the form of API forto network infrastructure),
tools for checking monitoring the workoperation of systems and informing
access tools (API) for remote file systems and disks as well as tape and
as well as specialized tools:
API tools for resource management: algorithms of resource allocation, language
versions and methods (tools) of resource specification, mapping resources
to applications – all tools should take into account such criteria as processors,
memory, disks, network connections, etc.,
IDS type tools (Intrusion Detection System),
user accounting/billing tools,
tools for supporting development of disperseddistributed software envisaged
for a Grid type computational network, programming environment in Grid,
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.
tools for automatic analysis and forecasting application capacity,
application development simulators,
debuggers of disperseddistributed applications.
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.
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
intelligent disperseddistributed software agents software searching and
integrated access interfaces to support materials through topical thematical
mechanisms of managing multi-language information accessible on the Internet
by teachers (multi-language search, automatic translation, etc.),
data replication mechanisms and WWW buffering (caching).
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.
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,
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)
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
integrated access interfaces to training materials (portals),
video conferencing tools,
group work tools in interactive environments (virtual classes),
tools for expanding standard information media by interactive elements,
e.g. interactive television, electronic publishers, hybrid systems,
specialized components for supporting handicapped teaching of handicapped
tools for developing interactive, multimedia modules and training materials
for digital libraries,
interfaces to data bases and data management systems, which facilitate
automatic linking the contents with the training subject (digital libraries),
access control methods, access rights management, accounting/ settlement,
knowledge assessment and examination mechanisms,
tools for coordination and organization of the training process.
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
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:
Applications of the above type require tool software, which will ensure:
managing regional ???? geographical three-dimensional infrastructure, based
on satellite data and/ or airborne,

Data will be stored and managed at the regional level. Therefore, it
is planned to introduce a pilot system realization program in selected
Environmental resources management Aapplications for managing environment
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,

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:

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.

applications (shared services).
Main requirements in respect of development of these services relate
Taking into account the need for applications referred to under it.

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
This system is a library of sources with multimedia objects (texts,
video, sound, images) along with metadata describing them as well as a

other applications, such as: virtual museums, electronic publishing, demand
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

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
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
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
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:
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
wireless networks (GPRS and third generation GSM – UMTS, local wireless
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:
servers of multimedia data bases (digital libraries),
systems of communication servers,
remote teaching systems, including:
In the realization of the program, also specialized network systems
will be required, connected with advanced research of techniques and advanced
remote teaching studios,
remote teaching rooms.
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
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.
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).
a system of digital video recorders with remotely steered positioning,
for interaction and video conferencing,
operator control desk for steering sound, lighting and image,
presentation terminal (e.g. for a lecturer),
equipment coding sound and image (e.g. MPEG2 coders),
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.
a system of digital video recorders with remotely steered positioning,
for interaction and video conferencing,
user terminals (at least 8 per room),
presentation equipment (slide projector, screen, film projector),
image and sound decoders (MPEG2),
operator control desk,
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:
2-4 GB of operating memory,
joint matrix of 100 GB.
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
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
- introduce direct connections with the following networks: vBNS+, Abilene,
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
