一种新的IP DiffServ over OBS网络体系结构及性能分析
New framework and performance evaluation for IP DiffServ over OBS networks
摘要
Abstract
IP Differentiated Services (DiffServ) has been standardized by the IETF and is considered as a promising IP QoS solution due to its scalability and ease of implementation. In this paper, we present a novel framework for IP DiffServ over optical burst switching (OBS), namely, DS-OBS. We present the network architecture, functional model of edge nodes and core nodes, the control packet format, a novel burst assembly scheme at ingress nodes and scheduling algorithm of core nodes. The basic idea is to apply DiffServ capable burst assembly at ingress nodes and perform different per hop behavior (PHB) electronic treatment for control packets of different QoS classes service at core nodes. Simulation results show that the proposed schemes can provide the best differentiated service for expedited forwarding (EF), Assured forwarding (AF) and best effort (BE) service in terms of end-to-end delay, throughput and IP packet loss probability.关键词
