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.
