摘要:

提出了一种将DiffServ over MPLS技术应用于深空网络通信中的网络QoS控制方案,以提高各种业务的QoS控制性能. 仿真实验结果表明,该方案较好地满足了深空通信网络中视频、语音等流媒体通信对传输延迟、丢包率等性能的要求.

Abstract:

With the rapid growing of business types in space communication network, there is a higher demand on the network performance. In this paper, we proposed a new scheme to improve the QoS performance,and introduced the DiffServ over MPLS technology into the deep space network communications. The simulation results show that our scheme commendably fulfills the demands of transmission delay, packet loss rate, and other performance requirements in stream media like voice and video business.

Key words: MPLS, AOS, DiffServ service, QoS
