摘　　要：以突发接入的模式将EPON接入到OBS网络存在的一系列问题,针对这些问题提出了一种新型边缘集成节点方案。该方案结合三级汇聚机制实现电域和光域的两种突发包的汇聚。通过OPNET仿真平台对直接互连和基于集成节点互连的方案分别进行建模仿真,分析和比较这两种方案的性能。a new edge integrated node scheme in accordance with the series of problems of EPON with burst access model accessing to the OBS network.The scheme implementation the convergence of burst packets in both Electric Domain and Optical domain combining with three level burst assembly mechanism.Finally modeling and simulation platform of the direct interconnection scheme and the scheme based on integrated node interconnection is done separately through the OPNET simulation platform,and then we analyse and compare the performance of the two schemes.
