作者 刘西恒 《电信网技术》 2008年第4期11-13,共3页
All-IP承载网是以IP技术为基础的多业务承载网,是运营商网络IP化和网络转型的基础。All-IP承载网与承载Internet等业务的传统IP网有较大的区别。传统IP网在QoS,安全性,可靠性,运营管理等方面存在不足,无法达到电信级的承载要求。而All-I... All-IP承载网是以IP技术为基础的多业务承载网,是运营商网络IP化和网络转型的基础。All-IP承载网与承载Internet等业务的传统IP网有较大的区别。传统IP网在QoS,安全性,可靠性,运营管理等方面存在不足,无法达到电信级的承载要求。而All-IP承载网虽然其技术基础仍然是IP,但已经从企业级演进成电信级。本文首先介绍了IP承载网的建网模式,然后重点介绍了骨干IP承载网传送方案和城域IP承载网传送方案。 展开更多

Mobility management is a very important function of mobile communication in all-IP radio heterogeneous network. In order to achieve an efficient mobility management, with low delay and low beacon overhead, a micro-mobile stream control transmission protocol (mmSCTP) scheme was proposed. This scheme reasonably utilizes SCTP features and elaborately designs execution-steps for vertical handoff. Moreover, it provides fast locating for idle mobile node when a session is initiated by the correspondent node. The analytical and simulation results show that the proposed scheme is effective in supporting fast vertical handoff and effective location management. 展开更多
