2 Transition – CDW – 15-June-2006

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

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

Overview

• Current assumptions

• A snapshot of what this might look like

• What do we need to know

5 Transition – CDW – 15-June-2006

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

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

9 Transition – CDW – 15-June-2006

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

13 Transition – CDW – 15-June-2006

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

Strawman: East to West…

Just an example to generate ideas

18 Transition – CDW – 15-June-2006

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

19 Transition – CDW – 15-June-2006

Key

• Juniper router on today’s Abilene

• Juniper router on new infra.

• Optical gear

• Cross-connect / Jumper

• Qwest OC 192

• NewNet OC 192 (reuse of hw)

Community input

42 Transition – CDW – 15-June-2006

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

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

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?
