随着信息技术的迅速发展,服务质量(QoS)对于网络来说越来越重要。QoS是网络的一种安全机制,一种用来解决网络延迟和阻塞等问题的技术。主要讨论了光网络中QoS的关键性指标,实现QoS的主要方法以及优缺点,论述了基于标签的光交换网的QoS实现方法。
With the rapid development of information technology, Quality of Service (QoS) is more and more important to the network. QoS is a security mechanism of the network, a technology used to solve the problems of network delay and congestion. This paper mainly discusses the key indicators of QoS in optical network, the main methods of realizing QoS and its advantages and disadvantages, and discusses the QoS implementation method of label-based optical switching network.
