摘　　要：无源光网络(PON)与光突发交换(OBS)网的互连是光分组传送网络发展的必然。文章分析了PON与OBS网互连存在的主要问题及已有的解决方案,提出一种聚合PON与OBS边缘节点功能的集成节点结构,研究基于集成节点的PON与OBS网络互连技术方案,提出基于业务流量的三级汇聚机制,分析结果表明三级汇聚机制可以保证业务等级,减少业务延时。The interconnection of PON and OBS network is an inevitable trend for the development of optical packet transmit network.This paper analyzes the main problems on interconnection of PON and OBS network. Proposes an integrated node strucutre which gathers functions of PON and the OBS edge node. This paper studies on the interconnection technique of PON and OBS network based on the integrate node and proposes a three-level burst assemble mechanism based on traffic flow. The analysis results indicate that the three-level burst assemble mechanism may guarantee the grade of service and reduce the latency of the service.
