1. Introduction
• The ICT community at these universities and
enthusiastic users exerted great pressure to
acquire their own network.

1. Introduction
• In 2004 the Ministry of Higher Education
responded to these needs by establishing The
Sudanese Universities Virtual Library project
(SUVL) and later being upgraded to Sudanese
Universities Information Network (SUIN.)

Main Goals
The main goals of this project are to provide
connectivity among the Sudanese educational
institutions, increase sharing of knowledge,
help universities build their information
infrastructure, and extend the value of digital
libraries.

Business Plan
•
•
•
•
•
•
UofK is the oldest and largest public university in
Sudan.
It has 5 campuses located in different geographical
locations in Khartoum.
In 1999 the campuses were connected in a WAN
based on different technologies (Optical fibre, frame
relay and wireless Tech).
The business plan for SUIN was based on the model of
the University of Khartoum (UofK) network
It has a similar users’ behaviour and service demand

Phased Plan
• A five years plan for the whole project was outlined
as follows:
• Phase I Implementation of the Sudanese
Universities Information Network (SUIN) 2005
• Phase II Implementation of the Sudanese
Universities Virtual Library (SUVL) 2006
• Phase III Network upgrade and optimization 2007
• Phase IV Content development 2008
• Phase V E- services provision 2009

1. Project Phase I
16/07/2015
19
Network Plan: Phase I (2005)
• 31 public universities were connected by
128 kbps data link using the Frame Relay
technology to a central router at the University
of Khartoum.
• 4 Mbps was provided for the Internet, using the
DSL technology.
• Cisco routers and fast Ethernet were the
technologies used.
16/07/2015
20
Network Plan: Phase I (2005)
• The service was provided by Sudatel.
• Why starting with that very low connectivity ?
• Because of the low budget available at that
time.
Frame Relay
128 Kbps / month ----------150 USD
VSAT
512 Kbps/ month -----------2000 USD
16/07/2015
Optical Fibre
1 Mbps /month -----------2500 USD

Network Plan: Phase I (network topology)
DTU 2801
Cisco 3660

22
Network Plan: Phase I (Obstacles)
• 10 fold increase of the traffic especially for
those universities for which SUIN were the
only path to the Internet.
• Due to small bandwidth; universities
looked for other solutions to get a better
bandwidth for the Internet.
• Weak operation due to lack of proper
contacts with the ICT people in the
universities.

Network Plan: Phase II (network topology)
• A web server and a firewall were
connected to SUIN and four databases
were implemented.
• Open source software is the used
• Figure (4) shows the network topology
with details concerning the web server and
firewall located in the University of
Khartoum.

Capacity Building
• In 2005: One training workshop in
Networking and Linux operation system
(70 trainers)
• In 2007: 3 training workshops in Linux
operating system ( 20 ICT specialists)
• In 2007; 2 Training workshops in quality
assurance of Libraries and building ecatalogues( 30 Librarians)

Project Cost
The Project is Funded by Governmental bodies:
1. The Ministry of Higher Education
2. The Sudanese Information Technology Fund
(SITF)
• The whole project is locally funded WITHOUT
any support from the International Bodies.
• THEN we need to strengthen the relation with
the supporting bodies
16/07/2015
40
Challenges
• Need for a decentralized design
• Need for a sustainable operation model.
• Completing the fiber networking with
acceptable prices
• Keeping the parties supporting the project
motivated
• Improve environment and salaries for ICT
professionals
• Applications and contents Development (
webhosting , email, elearning)
16/07/2015
41
Opportunities
• The National Regulator is the driving force
for the project
• The e-government project is a guarantee for
continuation
• Fiber will soon extend to southern Sudan
and will connect to Uganda
• Opportunity for STM1 provision
• Opportunity for Dark fibre (e-Government
project)
16/07/2015
42
Proposed Network Design
All connections through optical fibre
• Decentralization of the network can be
based either on:
1. Based on 4 universities where professional
ICT people and proper server rooms exist.
2. E-Government Project

Proposed Network Design II
• The university node will be used as the
gateway for the state and federal ministries and
departments at state capital.
• The federal ministries at Khartoum are
connected to the network by GE links by using
one of the following devices ( depending on size
of Ministry and its location)
-Net engine (router) NE20]
-Net engine (router) AR28
-Layer 3 switch S3900
16/07/2015
49
Proposed Network Design II
• VLANs
• Each university has its own VLAN
• Routing to take place at the nearest network
engine or L3 switch
• SUIN will be connected to the NTC Data
Center via network engine NE40 and GE link
