一种基于OBGP的支持区分服务的域间光路建立机制

An OBGP-based inter-domain lightpath setup mechanism with DiffServ support

通过光路边界网关协议(OBGP),用户可以控制跨越多个光域的端对端光路。在分析了OBGP的基础上,对其进行了扩展,以便更好地建立、控制和管理域间光路,同时提出了一种支持区分服务的域间光路建立机制,以保证高优先级用户的服务质量。仿真结果表明域间光路建立机制能有效地实现业务区分。

The network customer can control end to end lightpath by optical border gateway protocol （OBGP） between light domains. Based on the analysis, OBGP is extended to set up, control and manage inter-domain lightpath better. An inter-domain lightpath setup mechanism with differentiated service support is proposed to ensure quality of service（QoS）of high priority customers. Simulation shows that the proposed mechanism can effectively support DiffServ.
