Cogent - Transit network connectivity

Connectivity via Cogent worldwide tier-1 network:

"Cogent's end-to-end optical network consists of multiple metropolitan IP-over-WDM fiber rings located in Cogent's major markets throughout the United States and Europe. Cogent currently has a presence in over 85 markets throughout North America and Europe. Cogent's network provides each building or data center with up to 5 Gbit/s of dedicated bandwidth.

Layer 3 edge routers in each building are connected to Cisco Layer 3 Terabit core routers over two diverse optical paths. These core routers are tied together via an international backbone network consisting of multiple 10 Gbit/s DWDM optical links.

With a currently implemented capacity of 80 Gbit/s in the United States and 40 Gbit/s in Europe, Cogent's international IP network is the largest in the world and is scalable to a total capacity of over one Terabit.

The Cogent international backbone is designed to operate at OC-192, the MAN rings at OC-48. Our network uses ring redundancy and protected optronics to ensure survivability and availability of service. "
