GMPLS网络的近实时拓扑监视服务的性能(英文)

Performance of a near real-time topology monitoring service in GMPLS networks

提出了一种基于CORBA的网络管理系统模型和一种适用于GMPLS网络的准实时拓扑监视方案。根据LMP的MIB表得到初始化的拓扑信息,并通过分析SNMP的traps更新其拓扑信息。通过检测所提模型的延迟,证明文中所提出的拓扑监视方案可以实现准实时的要求。

In this paper, we present a prototype of a network management system based on the middleware CORBA, and an implementation of a near real-time topology monitoring service for GMPLS-based networks. This service gets the initial topology information using the MIB tables of LMP domain and updates this information by analyzing the SNMP traps. Afterwards, the topology information is flooded within the NMS with CORBA events. The latencies of our prototype are measured in order to check the fulfillment to our requirements for near real-time responses.
