Abstract

Network processor (NP) is a kind of programmable processor performing network computing, usually used to build a router. It is a new challenge that NP is used to build not only a router but also a data stream shaper. In this paper, the combination of routing algorithm and QoS assembly algorithm for OBS network is implemented using NP, besides, some key design issues such as the fast packet forwarding, the implementation of assembly algorithm and queuing discipline are also discussed in detail. The result shows that the edge router designed is capable of forwarding data streams coming from Ethernet at the average speed of about 880 Mbps.
