中文摘要：
现行网络拥塞控制机制已滞后于信息网络的高速发展,逐渐成为制约网络性能提升的瓶颈。从传统拥塞控制机制在复杂多变的异构网络环境中面临的诸多问题入手,概括总结了网络拥塞控制机制的研究发展现状,并强调了异构通信网络中拥塞控制问题的特殊性。在此基础上,提出了利用网络测量、多路径路由和跨层设计等技术手段和方法来设计适应异构网络环境的拥塞控制机制的新思路,并探讨了今后有待研究的技术问题、预期的目标和拟采用的研究方案。
英文摘要：
Existing network congestion control scheme has been dropped behind the rapid evolving information network technology and is becoming a network performance bottleneck.After introducing the problems and challenges current congestion control scheme faces in a complicated and changeable heterogeneous network.Its recent research development is summarized,during which characteristics of heterogeneous communication environment have been given particular attention.Then,making network measurement,multi-path routing and cross-layer design techniques in new congestion control scheme for heterogeneous network is proposed.And key technologies,anticipated targets and promising solutions are discussed.
