The PacketExchange backbone network is built using a multi-layer design developed to offer the highest level of performance and reliability.
Dedicated optical transport: PacketExchange's private optical long-haul network provides the foundation for an Ethernet-over-PBB-TE mesh between core backbone routers in each city. By allowing our optical transport system to detect and route around physical-level circuit problems, the need for convergence on inter-city routes is eliminated. This same infrastructure also provides dedicated data transport services to customers in PacketExchange's backbone cities.
Highly-scalable IP network: Built on top of PacketExchange's highly-resilient optical transport network, our layer-3/IP Network was recently re-engineered using Force10 routers to provide the highest levels of capacity and performance, even when utilizing enhanced services such as traffic analysis, DDoS mitigation and traffic filtering.
