The Research And Implementation Of A New Label Switch Verifying System Based On Network Processor

Network processor, which was not heard several years ago, becomes to be a new hotspot of the communication field very fast all by its programmable and powerful processes ability. Regional Code Label Switching protocol, which inherits the IPv4 packet exchange network and also refers the strongpoint of MPLS and ATM which use label to implement the fast packet forward, is a new label switching protocol. It tries to solve the insufficient of IPv4 address and gives a seamless transition plan. So they are a pair of a perfect match. The programmable characteristic of network processor is suite to implement the "regional code label switching" verifying system.First of all, this paper introduces the background of the network processor's appearance and situation which the regional code label switch protocol is brought out. Secondly, paper introduces the characteristic of network processor both in hardware architecture and software system. Especially, discusses the Intel Co. IXP2xxx series network processor particularly. After that, the main point of regional code label switch protocol is specialized briefly. At last, the paper centers around how to develop the RCLS test-bed system. It will discuss the architecture and key point of RCLS test bed both in data plane and control plane. And gives the way on how to improve the whole system's performance and how to evaluate the performance in mathematics theory.
