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.展开更多

This article analyzes the characteristics of IPTV services in traffic flow and authentication, and their requirements for the bearer network. It introduces ZTE' s solution to IPTV services and a successful application case in India.展开更多
