Abstract

Abstruct-The localized QoS routing techniques were proposed to achieve acceptable performance without exchanging global state information over the network. In such techniques the source nodes can estimate the network state and make the routing decision locally, hence reducing the signaling traffic at core routers and other network elements. However, using only locally collected information to make routing decision is not a completely reliable technique to achieve trusted QoS performance. The Localized Multi-Path Selection (LMPS) approach is proposed in this paper to overcome the common drawbacks of the localized techniques. The LMPS technique is a multi-path selection algorithm, which selects paths that are capable of satisfying the bandwidth requirement of the call, while at the same time trying to avoid the overloaded links to minimize the overall blocking ratio in the network.

VoIP网络中多路径路由的本地化业务质量

摘要:为了在不交换全局状态信息的情况下获得可接受的性能，提出了局部QoS路由技术。在这种技术中，源节点可以估计网络状态并在本地做出路由决策，从而减少了核心路由器和其他网元的信令流量。然而，仅使用本地收集的信息进行路由决策并不是实现可信QoS性能的完全可靠的技术。本文提出了一种局部多路径选择(LMPS)方法，克服了局部多路径选择方法的普遍缺点。LMPS技术是一种多路径选择算法，它选择能够满足呼叫带宽需求的路径，同时尽量避免过载链路，使网络中的整体阻塞率最小化。
