Research On Implementation Technology Of The ForCES Protocol In A Cluster-Based IP Router

With the increasing enlargement of network scale, the rapid increment of network speed, and the emergence of new technology of network and communication, people need more abundant, more convenient and more rapid network application and service. Because of these characters of Internet, the conception called "Internet of new generation" has appeared. To increase the scalability, flexibility and management of router system, especially cluster router system, we separate control elements of cluster router from its architecture, and use ForCES (Forwarding and Control Element Separation) protocol for communication between control elements and forwarding elements of a cluster router.In the paper, we introduce the background, purpose and significance of ForCES protocol firstly. Then we study how to implement a cluster router with ForCES protocol, through analyzing some relevant models which consist of distributed control platform. Afterwards, based on the analysis and research of the architecture and phase of ForCES protocol, we present the designing framework and analyze the protocol implement in detail.Furthermore, the paper focuses on the mechanisms of key implement technism. We analyze five key implement technism in detail, including separation technism of control packets and data packets, dynamic technism of protocol entities, high availability technism, de-coupling technism, and choosing technism of implement level of protocol entities. We present the thought of implement and solution for these key technism. Finally, we analyze related technism of the prototype system based OpenRouter model, and implement ForCES protocol in the open, extensible generic router prototype system. We have tested and evaluated ForCES protocol in the prototype system.
