RENU Design Overview October 2008
2
Acknowledgement 2 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.
3
Design Goals 3 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
4
Member Sites 4 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
5
PEPFAR Partners 5 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)

Global Connectivity 8 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

9 Kenya/Uganda Fiber Route
10
10 RENU PROPOSED NETWORK
11
RENU DESIGN - Transport 11 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
12
Phase I Transport 12 Including Masaka
13
Phase I Network 13 NiH, TASO Baylor, TASO Medical school
14
Refinements to Phase I 14 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?
15
NREN Nodes & Functions 15 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
16
POP Node 16 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
17
Refinements to Phase I (cont) 17 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?
18
POP Node Equipment 18 Two ONS 15454 ROADM One ONS 15454 Terminal Dual 7606 Routers 48x1GE Port Density 8x10GE Port Density
19
Aggregation Node 19 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
20
Aggregation Node Equipment 20 ONS 15454 ROADM Dual 7604 Routers 48x1GE Port Density Scalable to 10GE
21
Access Node 21 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
22
Access Node Equipment 22 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
