Introduction • The ICT community at these universities and enthusiastic users exerted great pressure to acquire their own network. 25/05/2017 12 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.) 25/05/2017 13 The Sudanese Universities Information Network 25/05/2017 14 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. 25/05/2017 15 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. 25/05/2017 16 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 25/05/2017 17 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 25/05/2017 18 1. Project Phase I 25/05/2017 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. 25/05/2017 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 25/05/2017 Optical Fibre 1 Mbps /month -----------2500 USD 21 Network Plan: Phase I (network topology) DTU 2801 Cisco 3660 25/05/2017 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. 25/05/2017 23 1.

Project Phase III 25/05/2017 29 Phase III: Network upgrade • We got Fund for 2008 • Optical Fiber for – 30 Public univ, – 10 private – 10 research centers 25/05/2017 30 Phase III: Network upgrade Current situation • Optical Fiber • Wireless • VSAT • Frame Relay 25/05/2017 31 Phase III: Optical Fiber 25/05/2017 32 Phase III: Network upgrade VSAT Wireless Frame Relay 25/05/2017 Optical Fibre 33 Operation and Maintenance ICT Committee Consultancy Committee Technical Team Librarian and Information Committee 25/05/2017 34 Operation and Maintenance Consultancy committee • 2 Univeristies VC • 2 CEO form universities networks • 2 Directors from Ministry of Higher Education 25/05/2017 35 Operation and Maintenance Technical Team • SUIN (CEO) • UofK CEO • SUST CEO • SUIN (CTO) • Three Technical assistant ( programmers) • Two part-time network engineers 25/05/2017 36 Operation and Maintenance The ICT Committee The ICTC is comprised of 31 ICT specialists (Heads of university computer centers (CEOs)). 25/05/2017 37 Operation and Maintenance The Libraries and Information Committee (LIC) The LIC is comprised of 13 librarians and information specialists in SUIN member institutions. 25/05/2017 38 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) • 25/05/2017 39 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 25/05/2017 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) 25/05/2017 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) 25/05/2017 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 25/05/2017 43 Proposed Network Design 1 • 25/05/2017 44 Proposed Network Design I • This design is centralized in 4 universities (4 NOCs) • Static Router • SNMP Activated in all Routers • 4 VLAN ID for each site (Internet, Data, Voice, Backup) • 25/05/2017 45 Research Institutions Proposed Network Design I • • • • WAN IP: 192.168.16.40/30 LAN IP: 172.16.0.x/24 VLAN ID: BW: 2Mbps 25/05/2017 • • • • Internet IP: X.X.X.X/30 WAN IP: Y.Y.Y.Y/24 VLAN ID: BW: 5Mbps 47 Proposed Network Design II The e-government project • 25/05/2017 48 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 25/05/2017 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 25/05/2017 50 25/05/2017 51 Thanks Telecommunication in Sudan 25/05/2017 53
