随着运营商规模的不断扩大,3G项目的不断上马,地市级本地传输网的网元数目成级数增长,传输网拓扑结构不断变化。对现有的本地传输网进行优化,使之在现有条件下如何提供更多的资源,如何减小网元间系统时延,如何加强系统稳定性,如何使网络经受更多的扩容考验并应对网络的可持续性发展,已经成为运营商必须面对的课题。
With the continuous expansion of the scale of operators, the 3G project has been launched continuously. The number of NEs in local transmission networks at the prefectural level has grown by stages, and the topology of transmission networks has been constantly changing. How to optimize the existing local transmission network so as to provide more resources under existing conditions, how to reduce the system delay between network elements, how to strengthen the stability of the system and how to make the network withstand more capacity expansion tests To cope with the sustainable development of the network has become an issue that operators must face.
