A scalable 10 Gb/s line-rate router with DiffServ support

A high performance router (DS-router) which supports DiffServ models by IETF effectively, is presented in this paper. This new router can work at OC-192 line-rate (10 Gb/s), provide 320 Gb/s non-locking switch capability, and facilitate true end-to-end quality of service (QoS) an an IP-network. Some features of the architecture and the design-implement of router are emphasized in this paper. According to the analysis of simulation results (delay, jitter etc.), we can draw the conclusion that DS-router can meet different QoS requirements ordered by the multiple classes of traffic very well.
