摘要: 充分利用路径分配和重定位路由流量方法,能有效地解决数据中心网路拥塞和延迟等问题,从而提升网络性能。基于多协议标签交换的流量工程技术MPLS-TE是优化数据中心网络中网络服务质量QoS的一种有效方法,从OSI参考模型网络层出发,结合QoS模型,设计了基于流量工程和路径分配的QoS算法,以保证数据中心网络的服务质量。实际测试结果表明,该算法能够提高网络传输效率、降低延迟和丢包率,特别是针对语音和视频流量的数据传输场景,在降低网络延迟和提升吞吐量等方面,效果显著。

Abstract: Network congestion and delay can be overcome by making full use of path allocation and relocation routing traffic methods.Multi-protocol label switching is one of the solutions to solve the QoS limitation of date center network service quality in IP networks.It designs a QoS algorithm based on traffic engineering and path allocation in combination with the QoS model to ensure the quality of network service.The network test results show that the algorithm can improve date center network transmission efficiency,reduce delay and packet loss rate,especially for voice and video traffic,the network performance has been greatly improved.

Key words: Date center, MPLS, QoS, Route, Traffic engineering
