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
