摘要
IPV4所提供的“尽力而为”服务,无法保证吞吐量和传送时延等服务质量(QoS)要求.文章探讨了IFTE针对QoS的需求而相应的优化模式:集成服务模型、区分服务、多标签交换协议(MPLS)等解决方案及相关的QoS技术支持,简要比较分析了IP QoS的主要技术性能,展望了IP QoS的发展方向.
Best-effort service offered by IPV4 can't guarantee the requirements of QoS such as the loading,downloading and transit latency,etc. QoS of IP. The article investigates Intserv,Diffserv and the relevant technical support, briefly comparing the quality of the modals of the current QoS,pointing out the developing trend.
