Abstract

In a multi-channel network based on wavelength division multiplexing (WDM), an efficient protocol is needed for transmitter and receiver to be tuned to same wavelength during message transmission time. This paper proposes a message scheduling protocol that can efficiently support variable-sized messages, where tunable transceiver has nonzero tuning time. In this protocol, once a node reserves one data channel, it can persistently use the reserved channel till message transmission is finished. Therefore, overhead due to tuning time of the tunable transceiver can be reduced. Moreover, the protocol does not require any global information. Therefore, it can operate independently of the change of the number of nodes, and any new node can join the network at anytime without requiring network initialization. With this protocol, one can avoid data channel and destination conflicts. The protocol is analyzed with a finite population model and the throughput-delay characteristics are investigated as performance measures.

파장 분할 다중화(WDM) 기반의 다중 채널 망에서는 송신 노드의 수신 노드가 메시지 전송 기간동안 동일한 파장으로 동조될 수 있도록 하는 효율적인 프로토콜을 제안한다 이 프로토콜에서는 일단 송신 노드가 하나의 데이터 채널을 점유하면 메시지 전송이 완료되기 전까지는 점유한 데이터 채널을 독점적으로 사용할 수 있으며 따라서 송수신 장치의 변조로 인한 오버헤드를 줄일수 있다 또한 제안된 프로토콜은 전체 정보를 필요로 하지 않기 때문에 망에 접속되어 있는 노드의 수의 변화에 무관하게 동작할 수 있으며 어떠한 새로운 노드도 망이 초기화 요구없이 언제든지 망에 접속할 수 있다 이 프로토콜을 이용하면 데이터 채널과 목적지 충돌 현상도 방지할 수 있다 제안된 프로토콜은 유한 노드 수의 모델에서 분석되었으며 처리율-지연 특성이 성능 측정을 위한 파라메타로서 조사되었다.
