摘要
众所周知,运营商互联网网络结构和路由策略可以决定网络流量的走向,影响运营商的建网成本和网络运维效率,甚至影响用户体验。分析骨干网与城域网互联的典型结构,选出合理的互联方式;基于优选的网络互联结构,分析路由策略的可行性,研究同一互联结构下不同路由策略的优缺点,为运营商互联网的构建、路由策略的制定以及网络的演进提供指导。
It is well-know that the network structures and routing policies of operators＇ networks determine the flow direction, affect the cost of network construction and efficiency of maintenance, and even influence subscriber experience. It analyzes the typical structures of the interconnection between backbone network and metropolitan area networks, and selects the most reasonable way of those topologies. In terms of the selective interconnection structure, it researches the feasibilities and the pros and cons of routing policies, thereby providing guidance for the routing strategies, the construction and evolution of the carriers＇ net- works.
