OSC Networking Engineering Update OSTEER June 13, 2007 Paul Schopis Associate Director OSC Networking

Backbone Update Ring 4 IRUs signed –Capital Review completed 8/06/07 –Gear is being processed 10 Gbps upgrade to parts of Rings 1, 2 and 0.

Backbone Update Looking two options for fall –Using I2 commodity peering service; so far have seen ~600Mbps –Will increase capacity with upgrades and when M120 goes in –M120s POs have been cut –Looking at Level3 using a 10 GigE pipe. Can buy as a burstable service, I.e. would really add a lot of “insurance” in uncertain times

Backbone Update Time Warner Telecom Mbps Considering changing commodity service from 4 OC-12, and 2 GigE to two 10 Gbps connections from different providers

Partners Still bringing K-12 ITC sites on TFN All are connected Installing of 6509s complete

New Directions Merit interconnect update - Buckeye anticipates 30 days for interconnect Level3 and Buckeye have finally agreed on terms and SIGNED!!! Original plan was to light with multiple 1 GigE lambdas on day 1 Will light with 10 Gbps since all gear is in hand Will share port with MERIT for NewNet

New Directions Pittsburgh connection under way First Optical unit is installed in Youngstown Have placed order to get fiber connected into our racks in Youngstown Waiting on LOA from QED to get connection completed in Pitt

I2 and NLR update Nothing much new Merger talks continue Councils have been elected

Joint Venture with State Governor gave Executive order Currently working on requirements and budget We will not compromise our services to accomplish this

Joint Venture with State Three basic designs on table –Separate Lambda etc - not likely –Completely shared infrastructure - not likely –Shared 10 Gbps Lambda, separate but interconnected routers They need enterprise services We need core services Pragmatic issue - They have two class B’s in their network and own AS MPLS with peering?
