Abstract

E-PON supports efficiently the increased Internet data traffic and efficient bandwidth assignment function by which the shared upstream bandwidth in the broadband access networks. In this paper, when different types of incoming sources are mapped into QoS-aware source and Best-Effort(BE) source, we propose the Dual-GPS schedulaer in E-PON that has the characteristics to provide delay and delay-constraint application, and maximizes the bandwidth to best-effort service. When transmit upstream data in E-PON, The proposed scheme supports the control capabilities of delay and delay-variation for required QoS flow through the novel bandwidth assignment scheme. Simulation results show our scheme outperforms the conventional bandwidth allocation scheme in controlling the delay and delay-variation of E-PON system.

E-PON 은 광대역 액세스 망에서 급증하는 인터넷 데이터 트래픽을 지원하고 대역폭의 동적 할당 기능을 효과적으로 지원한다. 본 논문에서는 E-PON에서 QoS를 고려한 트래픽과 최선형(Best-Effort) 트래픽의 두 가지 형식을 가진 트래픽이 유입될 때 QoS 서비스에 제약된 지연 시간과 지연 변이를 보장하고 최선형 서비스에는 대역폭을 최대학 보장해 주는 Dual-GPS 스케쥴러를 제안한다. 제안된 기법은 Ethernet 수동형 광 네트워크에서 상향 데이터 전송 시 새로운 슬롯할당 기법을 통하여 QoS 가 요구되는 전송 플로우에 대해 제약된 지연시간과 지연 변이를 제어하는 특성을 보인다. 시뮬레이션 결과 제안하는 기법이 기존의 대역할당 기법보다 지연 및 지연 변이 제어능력이 우수하다.
