Cogent Peering Strategy

Cogent is one of the five largest networks in the world in terms of the number of peers with which it works. Cogent executes an open peering strategy as part of providing its robust 100 Mbps and 1,000 Mbps Internet access services. The strategy is a combination of two separate, yet inter-related initiatives: extensive private peering and numerous public peering agreements.

Public Peering

Cogent has contracted for service with numerous public peering points for exchange of traffic. This initiative includes direct access to the West, Central and Eastern portions of the Cogent backbone for redundancy. Cogent has multiple connections at each of its peering and ATM-based NAP locations, ranging in size from OC-12 to multiple Gig-Es. This architecture allows Cogent to efficiently exchange a maximum amount of Internet-bound traffic with a high degree of redundancy.
