Abstract

An Ethernet PON(Passive Optical Network) is an economical and efficient access network that has received significant research attention in recent years. A MAC(Media Access Control) protocol of PON , the next generation access network, is based on TDMA(Time Division Multiple Access) basically and can classify this protocol into a fixed length slot assignment method suitable for leased line supporting QoS(Quality of Service) and a variable length slot assignment method suitable for LAN/MAN with the best effort. For analyzing the performance of these protocols, we design an Ethernet PON model using OPNET tool. To establish the maximum efficiency of a network, we verify a MAC protocol and determine the optimal number of ONUs(Optical Network Unit) that can be accepted by one OLT(Optical Line Terminal) and propose the suitable buffer size of ONU based on analyzing the end-to-end Ethernet delay, queuing delay, throughput, and utilization.

Ethernet PON(Passive Optical Network)은 최근 활발하게 연구되고 있는 경제적이고 효율적인 가입자망이다. 차세대 가입자망인 Ethernet PON의 MAC(Media Access Control) 프로토콜은 TDMA(Time Division Multiple Access)방식을 기본으로 하며, QoS(Qualify of Service)를 보장해야 하는 전용회선(Leased Line) 가입자에 적합한 고정 할당 방식과 LAN/MAN의 최선형(Best Effort) 방식에 적합한 동적 할당 방식으로 나눌 수 있다. 본 논문에서는 이들 프로토콜의 성능을 분석하기 위하여 OPNET 시뮬레이션 도구를 이용해 Ethernet PON 모델을 설계한다. 설계된 모델에 대한 단대단 Ethernet 지연(end-to-end Ethernet delay), 큐잉 지연(queuing delay), 처리(throughput)과 사용률(utilization) 분석을 통해서 MAC 프로토콜을 검증하고, 하나의 OLT(Optical Line Terminal)가 수용할 수 있는 최적의 ONU(Optical Network Unit) 개수를 산정한다. 또한, 적정한 ONU의 버퍼 크기를 제안하여 Ethernet PON의 망 효율을 극대화하는 방안을 제시한다.
