服务质量(QoS)保障1.端到端QoS保障多业务IP承载网必须能够区别业务所需的QoS,传统的IP网络采用的过载设计容易发生拥塞导致丢包。由于视频(组播)和VoIP等业务无法很好处理丢包,因此要求对视频和语音数据流必须能够区分优先级,以确保拥塞情况下的优先调度。
Quality of Service (QoS) Guarantee 1. End-to-End QoS Guarantee Multi-service IP bearer network must be able to distinguish the QoS required by the service. Overloading in traditional IP networks is easy to cause congestion and result in packet loss. Because services such as video (multicast) and VoIP do not handle packet loss well enough, it is important to prioritize video and voice traffic to ensure prioritization in congested situations.
