Research On Multicast And Transaction Management In Forces Channel

Open and programmable network architecture based on the idea of Forwarding and Control Element Separation(ForCES) is one of the most important research directions of the next-generation network equipment. This new architecture is better able to serve the requirements that are put forward by the development of communication technology and the explosion of new applicable services today. In order to improve transmission efficiency, save network bandwidth and reduce the delay, this paper researches on the multicast technology and transaction management of the ForCES channel.Based on the analysis of the requirements of multicast transmission mechanism in the ForCES channel, this paper proposes a reliable multicast solution applied to the ForCES channel, analyzes the interaction procedure and the interaction module with Petri net based on the reliable multicast transmission, and takes advantage of IPSec as a security issue solution of reliable multicast. In order to implement the reliable multicast scheme we designed, this paper first defines the types and functions of message used in reliable multicast transmission and describes the structure of all types of message in details; then, analyzes the position and main function of CE's and FE's reliable multicast module in ForCES architecture; at last, takes advantages of UML to introduce the detailed design of CE's and FE's reliable multicast module. In order to reduce the delay in transaction operation between CE and FEs, this paper analyzes the ForCES distributed transaction module based on 2PC, proposes the transaction management mechanism which has modeled by Petri net.At last, this paper tests for functionality and performance of reliable multicast, and takes a test of transaction management based on reliable multicast. The experiment results show the feasibility and validity of our design.
