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

Generic Plan
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

Generic Plan
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?
