History of BSU Networking
Computer network of the Belarusian State University
has been developing since 1992.
In 1992:
• the network of BSU connected a library of BSU and a few
study rooms;
• there was one file server and one e-mail server in the
network;
• faculties and departments had access to e-email by
means of dial-up networking;
• link established to Internet had bandwidth of 14,4 Kbit/s
Nowadays
BSUNet is the biggest network compared to ones of
other educational institutions in Belarus
The network consists of two parts:
• Corporate BSU Intranet network;
• Research informational network (NIKS), providing access
to national and international scientific and educational
resources for external users.

The network of BSU is wired by optical fiber channels of 1 Gbit/sec bandwidth to the network of
the National Academy of Science Bas-Net and the network of the Ministry of education
UNIBEL. For access to GEANT and Internet networks a link to Bas-Net network is used. At
present the bandwidth of the link can be estimated about 100 Mbit/sec.

BSUNet
• The corporate network of BSU
counts more than 4,200
workstations.
• All employees and students
of BSU (more than 22,000
users) have personal logon
credentials (login and
password) and have free and
unlimited access to BSUNet,
GEANT and Internet with
LANs in all our buildings.
• Teaching staff of BSU are
allowed to log into the
network from their homes
using dial-up access.

• Students of BSU can work on
their own in computer
classrooms and labs of the
university, faculties and
departments.
• Hostels of BSU are also
connected to the corporate
network (most of them –
using optical fiber channels).
• There are LANs deployed
inside the hostels and
students have access to
BSUNet and Internet from
their suites.

The backbone of BSU corporate
network is built using optical fiber
channels.
These channels interconnect 29
educational and administrative
buildings, inside of which we have
LANs configured.

Computer and telephone networks of BSU
are united into a single multi-service network
which uses shared optical fiber channels.
Nowadays telephone network of BSU counts
about 1400 telephone end-points.

Information Resources
BSUNet hosts many different information resources. The
most important of them are:
• external Web-site (www.bsu.by)
• internal Intranet-site
The Intranet-site serves as an access point to internal
information resources of BSU. Those resources essentially
consist of:
• educational materials of all 16 faculties in more than 1200 learning courses
(they are united into a common database with authenticated access. The
access to the educational materials is provided for students by e-University
specialized network system);
• resources of the university’s library: electronic catalogue and full-text
documents;
• automated informational system which includes databases of students,
employees, scientific and research projects and many others.

• The second part of
BSUNet is external
network.
• This is a research
informational computer
network created by BSU.

By means of NIKS
we provide access
services to national
research and
educational
networks (BSUNet,
Bas-Net, UNIBEL),
to GEANT and
Internet for nonBSU educational
institutions and
institutions of
scientific research,
as well as their
students, who live in
hostels in Minsk.

Researches and Innovations
Design and development of BSU network is based on the
results of own research in the area of computer networks.
Since 2001 we conduct intensive research on algorithms and methods
for optimal design of computer networks. So far we have obtained the
following results:
• performed a classification of information resources by their purpose, request
processing workflow and internal structure and proposed analytical
expressions and analytical models for QoS estimates of user request
processing;
• designed and implemented an extension to NS2 modeling tool for simulated
modeling of user interaction with information resources;
• invented an iterative decomposable method for optimal information resource
placement inside computer networks of fixed topologies;
• developed an approach for optimization of resource placement using parallel
genetic algorithms.
In 2007 we won a contest for the concept development of the
informational environment of the Ministry of education of the
Republic of Belarus.

Researches and Innovations
Based on the accomplished research we developed new
systems of content management (CMS). They allow rapid
development and management of Web-sites systems.
For instance, we can take a Web-sites of educational
institutions in Minsk. It consists of more than 400 semantically
linked websites, which participate in informational exchange.
This exchange is not only limited to data exchange (news etc.),
but allows informational service exchange as well, surveys and
polling for example.
In 2008 we developed a new Web-site of the Ministry of
education and the National educational portal. These websites intensively use WEB 2.0 technologies. These
technologies provide users with multiple and flexibly
configured services.

Looking forward to the future
• the prevalence of electronic educational resources over
traditional ones (up to 70%);
• the vide use of mobile (portable) computers for access
to the informational resources;
• the growing number of students who have personal
computers, mobile devices first of all (>90%), the need to
be always on-line;
• the development and a great demand in digital media
technologies;

Looking forward to the future
The actual directions of development
of BSU network nowadays are:
• creating of infrastructure for wireless broadband access into
all buildings of the university
• upgrade of external channels bandwidth to GEANT and
Internet up to 200 Mbits/sec;
• development of educational informational resources system,
creation of electronic tutorials for all main courses;
• deployment of fully functional electronic library of BSU
• organization of regular video-broadcasting and videoconferencing in BSU network;
