Independent network mode results in high network investment, difficult operating and maintenance tasks, and low capability in supplying new services. Different networks integrating with the IP network is a certain trend, and multiple services will be born on a consistent IP/MPLS network. Carriers from all over the world are building new generation IP multi-services carrier networks www.h3c.com

Because the entry lookup and QoS scheduling demands and the corresponding models are stable, using the ASIC technology for entry lookup and QoS scheduling can improve router performance significantly. Integrated with the high performance of ASIC and flexible scalability of NP, the SR8800 adopts a three-engine forwarding structure, namely, NP service engine, QoS engine and entry lookup engine. The service engine uses the NP technology to support flexible service scalability and upgrade. The QoS engine and entry lookup engine use the ASIC technology to support high-performance QoS and entry lookup capabilities. www.h3c.com
Architecture-High Capacity and Performance An SRPU has two crossbars embedded to save slot space, and is enough to ensure normal operation, while double SRPUs offer hot-standby 1+1 redundancy and support 1.44T switching capabilities.
