Abstract

In this paper, We analyzed the protocol to improve the performance of the multicast traffic processing in WDM networks. In the protocol, control channels are devided into contention-less minislots 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 conflicts can be reduced with the use of contention-less minislots. For the multicast traffic processing, the theoretical analysis and computer simulation are important to estimate the network performance and to calculate the optimized number of contention-less minislots. In this paper, the state transition probability of the number of contention-less minislots and arrival 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.

본 논문은 파장분할 다중화(WDM: Wavelength Division Multiplexing) 통신망에서 멀티캐스트 트래픽의 특성을 향상시키기 위해서 제어채널을 분할한 프로토콜의 성능을 해석하였다. 이 프로토콜에서 제어채널은 경쟁 미니슬롯 영역과 비경쟁 미니슬롯 영역에 우선적으로 등록되므로써 제어채널 경쟁과 목적지 충돌을 줄이게 된다. 멀티캐스트 트래픽을 처리하기 위해서 비경쟁 미니슬롯 영역의 채널 수를 최적화하고 성능을 예측하기 위해서는 이론적인 해석과 시뮬레이션에 의한 검증으로 해석하였다. 시스템의 성능 개선을 최대로 하기 위해 최대 비경쟁 미니슬롯 수는 망의 채널 수와 동일한 것으로 하여 그 특성을 이론적으로 해석하고 그 결과를 시뮬레이션에 의해서 검증하였다.
