摘要
针对软交换网络中信令流、媒体流和维护流等业务流的交互需求,结合SOFTX3000软交换设备、UMG8900通用媒体网关设备和UA5000用户接入设备相关单板的工作原理,分析了采用二层组网模式的承载网络存在的弊端,提出了基于OSPF(Open Shortest Path First,开放式最短路径优先)协议的三层路由组网模式,并在某电话局软交换网络中得到应用。经分析,采用三层路由组网模式相比于二层组网模式具有更高的安全性和可靠性。
To meet the interactive requirements of signaling flow, media flow and maintenance flow in soft switching systems and in consideration of the operation principles of SOFTX3000 soft switching unit, UMG8900 general media network gateway and UA5000 user access unit, a three-layer routing networking model based on OSPF （Open Shortest Path First） protocol is proposed, following analysis of the drawbacks of hosted networks using two- layer networking model. The proposed model has been suecessfully used in the soft switching network of a telephone exchange. In comparison, the three-layer routing networking model is superior over two-layer networking model in security and reliability.
