AboveNet IP Backbone Architecture

Tier 1, high-performance global optical IP network

• Performance Engineering
• Unparalleled peering
• Network security leader

The AboveNet backbone has been optimized for scalability, survivability, performance, efficiency and manageability. The current AboveNet network consists of a set of sites interconnected in a partial mesh and will be extended to accommodate a larger number of sites moving toward a two level hierarchy. This two level approach allows arbitrary scaling at either level according to various technological and business imperatives.

AboveNet hubs are connected via AboveNet fiber and DWDM equipment terminating the fiber. This allows AboveNet to scale the bandwidth as needed. Backbone trunks range from OC12 to OC192 and AboveNet uses Packet Over SONET IP(POSIP) on all trunks due to its increased efficiency over ATM. This infrastructure enables AboveNet to deliver a high level of availability and fast Internet response for both domestic and international traffic.

Not just cutting-edge fiber optic networks, but we also have industry-leading peering arrangements which allow this network to be fully adaptable, redundant, and intelligent. We have over 430 peering arrangements, with over 1,000 sessions.
