摘要
基于同步数字体系(SDH)之上的综合业务传送平台(MSTP)已成为运营商建设多业务城域网的首选。技术的发展、层出不穷的新业务迫使人们对MSTP进行频繁的更新换代。一方面,围绕数据业务的优化改进促使一系列新技术如链路容量调整方案(LCAS)、通用成帧协议(GFP)、多协议标签交换(MPLS)、弹性分组环(RPR)等不断走向商用;另一方面,如何与即将开展的大规模3G传输网络建设相结合,低成本、高效率地为3G业务提供更好的传送通道,并进行相应的优化,这已经成为MSTP必须面对的问题。
The SDH-based MSTP has been the top selection of the operators in the construction of a multiservlce metropolitan area network. With the development of new technologies, new services that are emerging endlessly have compelled MSTP to upgrade frequently, On one hand, the optimization of data services have impelled a series of new technologies, such as LCAS, GFP, MPLS and RPR, to turn into business applications; on the other hand, it has become important issues that MSTP must confront how to combine with the on-going large-scale construction of the 3G transmission networks, support the 3G services with low-cost and highly-ettieient transmission channels and perform appropriate optimization of them,
