파장분할 다중화 통신망에서 제어채널분할을 이용한 멀티캐스팅 프로토콜의 성능분석

Abstract

In this paper, Wc analyzed the protocol to improve the pcrfonnance of the multicast traffic processing in WDM networks. In the protocol,control channels are divided into contention-less mWalota and contention minislots. And the packets which fail to have successful reservation in the present time slot have priority to have successful reservation in the contention-less minislots of the next time slot. Therefore, control channel contentions and destination coofllctH can be reduced with the use of contention-less minislots. For the multicast traffic processing, the theoretical analysis and computer aimuladm are important to estimate the network performance and to calculate the optimized number of contention-less minislots. In this paper, the state tnmsition probability of the number of contcntion-less minislots and anival packets are calculated using 4-dimension matrix. The maximum number of contention-less minislots is equal to the number of channels for maximum performance improvement of the system. It is theoretical analysis and prove to computer simulation the performance of the protocol.
