10 Gigabit Network Plans

1. 10 Gigabit Network Plans MSU IT Conference August 1, 2007 Doug Nelson

2. Today’s Backbone Network • 1 Gigabit/sec backbone • 140 Buildings • 90 Backbone routers • 7 Fiber loops • 8 Cross-connect points

3. Today’s Backbone Network • External network connection • 1 Gigabit/sec path to Merit • Single path

4. Backbone Network (Overall)

5. Backbone Network (Loop 1)

6. Backbone Network Protocols • Layer 3 (routed) IP network • No VLANs across backbone • IPX and Appletalk removed in 2006

7. The Future Backbone Network • 10 Gigabit/sec backbone • 3-Tiered Network Architecture • Six Tier1 (routing/aggregation) points • ~90 Tier2 buildings (redundant paths) • ~50 Tier3 (spur) buildings

8. The Future Backbone Network • External network connections • 10 Gigabit/sec paths to Merit • Second path for redundancy • 10 Gigabit/sec path(s) to MiLR (Michigan Lambda Rail)

9. Campus core network

10. Sample Tier2 backbone loop

11. Sample Tier1 site

12. Tier1 site: Computer Center

13. Tier1 site: Comm Arts

14. The Future Network • IPv4 + IPv6 • Redundant routing (VRRP) • Some layer 2 (VLANs) across backbone • Virtual Networks • Public network • Res Hall network • “Secure” network

15. The Future Network • Integrated security components • “Security Enforcement Points” • Inter-zone firewalls • Connection between Virtual Networks • Inter-VLAN firewalls • Connection between VLANs within a Virtual Network

16. Virtual Networks

18. 10 Gbps Network Hardware • Tier1: Extreme Black Diamond 10808 chassis • 1.2 Tbps capacity • 48 ports of 10 Gigabit Ethernet • 480 ports of 1 Gigabit Ethernet • Line rate capacity for all ports and functions

19. Extreme Black Diamond 10808

20. 10 Gbps Network Hardware • Tier2: HP Procurve 5406 chassis • 240 Gbps capacity • 24 ports of 10 Gigabit Ethernet • 144 ports of 1 Gigabit Ethernet • Line rate capacity for typical configuration
