  1. RENU DesignOverview October 2008

  2. Acknowledgement The bulk of information contained in this presentation is the result of a design session in Seattle Washington in November 2007 between RENU, IEEAF and UW members. 2

  3. Design Goals • Create National Research & Education Connectivity • Phased implementation approach • Accessibility for Participants • Equality of Service for Participants • Maximize Network Reliability • Ensure Network Scalability • Minimize Operational Complexity • Access to cheaper Internet bandwidth 3

  4. Member Sites • Uganda Christian University • Uganda Martyrs University • Kyambogo University • Makerere University and Business School • Mulago Hospital • Gulu University • Mbarara University of Science and Technology • National Agricultural Research Organization • Uganda Virus Research Institute • Joint Clinical Research Center • National Institute of Health funded sites 4

  5. PEPFAR Partners • Kampala Node • Faculty of Medicine (MakNET) • Makerere School of Public Health (MakNET) • Infectious Diseases Institute (IDI) (tunnels thru MakNET) • Mulago Hospital (MakNET) • The AIDS Support Organisation (TASO) • Makerere University John Hopkins University Program (MUJHU) (Phase I) • Paediatric Infectious Disease Center (PIDC) Baylor Program • Walter Reed HIV Program (Phase I) • Entebbe Node • Uganda Virus Research Institute (Phase I) • Center for Diseases Control (CDC) (Phase I) • National Institute of Health funded sites (Phase I & II) 5

  6. Potential Future Sites • Ndejje University • Bugema University • Busoga University • Nkumba University • Kampala International University • Kampala University • Aga Khan University • Kigezi International School of Medicine • Kumi University • Kabale University • National Teachers Colleges 6

  7. Some Locations 7

  8. Global Connectivity • SEACOM cable landing in Mombasa, Kenya with a 10G handoff • Dark Fiber from Mombasa to Kampala lit with Cisco 15454 DWDM Equipment • 10G Global connectivity provided to RENU by IEEAF at the Technology Exchange Point (TEP) in Kampala 8

  9. Kenya/Uganda Fiber Route 9

  10. RENU PROPOSED NETWORK 10

  11. RENU DESIGN - Transport • Cisco 15454 DWDM equipment preferred • Can support leased Lambdas • Ethernet support for speeds of 1G and 10G • SDH support for speeds of 2.5G and 10G • Provides RENU backbone, plus local on-ramp capabilities 11

  12. Phase I Transport Including Masaka 12

  13. Phase I Network Baylor, TASO Medicalschool NiH, TASO 13

  14. Refinements to Phase I • Moving Masaka Node from Phase II to Phase I • Collaborate with NiH to include Rakai station • Include Uganda Martyrs University, omitted in earlier design (located 2km off Masaka rd, about 80km from Kampala) • Liaise with UTL to establish connectivity options available (Tom Darkin) • Fiber terminations for Phase 1 Nodes • In some cases fiber does not terminate at proposed node locations • Does UTL donation include providing last-mile connectivity where it does not exist? 14

  15. NREN Nodes & Functions • POP Node collocated in the TEP • Provide Gateway to other networks, national and international • Policy enforcement and network protection • Layer 2 interconnectivity point • Aggregation Nodes Strategically located in country • Local routing center for remote areas • Connector site for other local network participants • Operational support for NREN • Offers both Layer3 and Layer2 capabilities • Access Node • Managed participant connectivity to RENU 15

  16. POP Node • N-Way DWDM Transport Systems • Dual Routing Platform • 10GE External Interfaces • Switching Capabilities • Day One - 48 Ports of 1GE Optical Connectivity • Day One - 8 Ports of 10GE Optical Connectivity • eBGP for External Routing • iBGP for Internal Routing of Externally Learned Routes • OSPF for Internal Routing of Infrastructure Routes • 802.1Q Support for L2-VPNs 16

  17. Refinements to Phase I (cont) • Routing • OPTION 1: OSPF proposed for RENU backbone • Will need close collaboration amongst RENU institutions to come up with a unified routing policy, implemented by RENU • OPTION 2: Each member can obtain own AS number to enable direct peering on the RENU backbone • DISCUSS • Access to Internet • Is commodity Internet access part of the donations? • If it is, what are the implications for current providers? • If it is not, can RENU purchase bandwidth internationally? 17

  18. POP Node Equipment • Two ONS 15454 ROADM • One ONS 15454 Terminal • Dual 7606 Routers • 48x1GE Port Density • 8x10GE Port Density 18

  19. Aggregation Node • ROADM or Terminal DWDM Transport Node • Dual Routing Platform • 10GE Interface Capable • Switching Capabilities • Day One – 48 Ports of 1GE Optical Connectivity • Can support 8 Ports of 10GE Optical Connectivity • eBGP can be supported between RENU and network Participants • iBGP for internal routing of externally learned routes with TEP • OSPF for internal routing of infrastructure routes • 802.1Q Support for L2-VPNs 19

  20. Aggregation Node Equipment • ONS 15454 ROADM • Dual 7604 Routers • 48x1GE Port Density • Scalable to 10GE 20

  21. Access Node • Dual Routing Platform • 1GE Interface Capable scalable to 10GE • Switching Capabilities • Day One – 12 to 48 Ports of 1GE Optical Connectivity • eBGP can be supported between RENU and network Participants • iBGP for internal routing of externally learned routes with TEP • OSPF for internal routing of infrastructure routes • 802.1Q Support for L2-VPNs 21

  22. Access Node Equipment • ONS 15454 ROADM • Dual Routers (in some locations, might be lower specs than 7604)‏ • 12-48x 1GE Port Density • Scalable to 10GE • For places with small LANS 22

  23. Phase II Connectivity 23

  24. Phase II Transport 24

  25. Phase III Connectivity 25

  26. Phase III Transport 26

  27. Services - proposed • Content hosting for member institutions • DNS administration for .ac.ug • LIR for member institutions • VOIP between member institutions • Content mirroring 27

  28. Challenges • Transition from current environment where RENU members are served by different bandwidth providers • Creating sustainability 28

  29. Reflections!Questions or Comments? 29

  30. Technology Exchange Point • World Class Environment (redundant power, space, cooling) • High Bandwidth, High Reliability Global Connectivity • Carrier neutral facility • Free co-location space for RENU POP • International, National and Local Peering Exchange • Actual site of TEP is still TBD, planned to be near to Makerere University • Cisco Dense Wave Division Multiplexing (DWDM) Equipment • Cisco Routing/Switching Platforms supporting 10GE 30
