摘要
The Next Generation Network (NGN) (Softswitch) is a universal multi-service network designed for the transmission of voice, video and data on a packet switching basis. It is based on the IP bearer network. This article analyzes the features of different bearer modes in the respects of QoS, security and resource utilization. In order to bear NGN, QoS requirements should not be ignored. For this reason, QoS requirements are described from the view of delay, jitter, packet loss rate and bandwidth. At the end of this article, ZTE' s networking solution is given.
