1. M A R E N Malawi Research and Education Network: Backbone Network Design Implemented & Planed Anthony Muyepa Harry Gombachika, Rodwell S. Bakolo MAREN Co-founders and Task-Force members www.malico.mw/maren (soon www.maren.mw)‏www.malico.mw/maren

2. Outline of Presentation Background Network Design Opportunities Challenges

3. AIM The aim of MAREN is to develop the infrastructure to facilitate wide use of Internet Technology in teaching, research and sharing of information resources at affordable cost.

4. Objectives Integrating all the Malawi Higher Education and Research Institutions in a one national broadband Network to offer high-speed, quality and economically sustainable services to member institutions including access to the global Internet. Providing a platform for researchers in Malawi to participate in collaborative research and development projects nationally and on the international stage and access global cyber-infrastructure

5. Objectives continued Provide the infrastructure to support the development, sharing and delivery of innovative online education content and applications nationally and internationally and the development of learning and research communities across Malawi. Facilitate access to national and international information resources to optimise the efforts of researchers to create, manage, discover and disseminate knowledge through services such as video conferencing, E-Learning, E-mail, etc..

6. Existing Partnerships Working with ESCOM to utilise the fibre available to MAREN for academic connectivity for 3 yearsESCOM Working with MACRA, for harmonious regulatory conditions or academic connectivityMACRA Working with MTL to access metro fibre, towers, and ducts Collaborating with MISPA on the Malawi Internet Exchange activities and gain peering rights. International Collaboration through UbuntuNet Alliance for Research and Education NetworkingUbuntuNet Alliance for Research and Education Networking

10. ESCOM Fibre in relation to locations MAREN member institutions

11. Design Considerations – Blantyre Lilongwe Backbone Solution should address the following 2 Gigabit bandwidth between Blantyre and Lilongwe Reliable network – not subject to obstructions and interference Accommodate future bandwidth requirements with incremental upgradeability Low cost extensibility

12. Suggested Network Design Actively switched daisy fiber chain is proposed, as opposed to passive fiber Each site node will have an active node, and will requires a switch, a fibre distribution frame and a transceiver for each fibre cable that connects the node Traffic not destined at each switch is relayed to next.

15. Motivation for active daisy chain Number of fiber strands not dependent on number of sites New site requires fiber pulled from nearlest connected site Cost of fiber is reduced, while requires same number of switches

16. 16 Philosophy of the Network

17. INSTALLED NETWORK

18. International Gateway Licence Negotiated at length with MACRA for Licence to operate a national network which will connect Tertiary Education and Research institutions and then connect regionally. MACRA had already been very facilitative in granting MALICO a 5 year academic VSAT licence International Gateway License granted to MAREN to peer with other UbuntuNet Alliance members across borders at the MAREN Launch

19. Challenges Ownership Elaboration of final technology blueprint and user policies Setup of implementation team and institutionalization of MAREN Definition of campus network standards and network management guidelines Identification of additional partnerships and project funding
