1. Network Transition Matt Zekauskas Internet2 Community Design Workshop 15, 16 June 2006 Indianapolis, IN

2. Transition – CDW – 15-June-2006 2 Transition: what it means to me Moving existing IP-level connectivity from current Abilene to the new network 15 month horizon Moving routers from Qwest space to Level3 space, and using our own OC 192’s instead of Q-Wave OC 192s Re-homing connectors to Level3 space

3. Transition – CDW – 15-June-2006 3 Caveats Any specific examples herein are just that – examples The real plan will be built with your input Many things may change, e.g., sequencing, number of routers, router placement

4. Transition – CDW – 15-June-2006 4 Overview Current assumptions A snapshot of what this might look like What do we need to know

5. Transition – CDW – 15-June-2006 5 Assumptions Re-use existing Juniper T-640s Similarly, core links left as OC 192 for now Reduction in number of routers possible because of flexible optical network, fewer connectors due to aggregation For now, assume 8 routers: NYCM, CHIN, DNVR, STTL, LOSA, HSTN, ATLA, WASH Drops IPLS, KSCY, SNVA Another possibility is 9, replace DNVR with Salt Lake & KSCY; there are others

6. Transition – CDW – 15-June-2006 6 Generic Plan Ensure optical plant built to target location(s) Place router in Level3 space Use temporary fiber + optical gear to patch between Qwest and Level3 space Use optical plant to attach to adjacent routers that currently exist in Level3 space with our own OC 192’s

7. Transition – CDW – 15-June-2006 7 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA HSTN STTL, DNVR via SNVA HSTN via SANconn. Generic Plan

8. Transition – CDW – 15-June-2006 8 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA HSTN STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

9. Transition – CDW – 15-June-2006 9 Generic Plan (cont) Patch between Qwest & Level3 space Move connectors that can move to Level3 space easily (or have been scheduled appropriately) Patch connectors that need additional time to move Temporarily patch Qwest backbone circuits to adjacent routers in Qwest space

10. Transition – CDW – 15-June-2006 10 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA HSTN STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

11. Transition – CDW – 15-June-2006 11 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA HSTN STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

12. Transition – CDW – 15-June-2006 12 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA HSTN STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

13. Transition – CDW – 15-June-2006 13 Generic Plan (cont) Router in Qwest space can now be decommissioned, and reconfigured for the next installation Abandoned Qwest backbone circuits can be released back to Qwest Once all peers and connectors are homed to Level3 space, remove temporary optical gear and release fiber

14. Transition – CDW – 15-June-2006 14 Example: Los Angeles QwestLevel3 T-640 Infinera ADM SNVA STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

15. Transition – CDW – 15-June-2006 15 Example: Los Angeles QwestLevel3 T-640 Infinera ADM STTL, DNVR via SNVA HSTN via SAN T-640 conn. Generic Plan

16. Transition – CDW – 15-June-2006 16 Example: Los Angeles QwestLevel3 T-640 Infinera ADM STTL, DNVR via SNVA HSTN via SAN T-640 conn.

17. Strawman: East to West… Just an example to generate ideas

18. Transition – CDW – 15-June-2006 18 What this doesn’t show Connector sequencing (when they might move to new router locations) When we can pull optical gear out of Qwest locations Exact geographic locations Strawman – East to West

41. Community input

42. Transition – CDW – 15-June-2006 42 What do we need to know? Key questions: If you are already in Level3 space Where? Dark fiber? Lit? What constraints do you have on a move? Can we together generate a mutually acceptable schedule? or When do contracts for Qwest PoP access circuits expire? Early adopters will likely determine schedule

43. Transition – CDW – 15-June-2006 43 What do we need to know? Would you be able to move up? 1G? 10G? Do you have any fiber between Qwest pops with Abilene routers and the local Level3 PoPs? We have some in the HOPI cities (LOSA, STTL, CHIN, NYCM, WASH)

44. Transition – CDW – 15-June-2006 44 Other Questions If you have a small-ish connection, have you considered working with others in your region to aggregate? Redundancy needs in the future? Commercial access desires?
