摘要
针对目前IP网络亟待解决的QoS问题,分析了区分服务(DiffServ)模型的体系结构,研究了区分服务实现IPQoS的控制策略,包括支持区分服务的各种缓冲管理、队列调度算法及拥塞控制机制.最后用网络仿真软件NS2在Linux环境下搭建了实现区分服务的仿真实验平台,在该平台上对区分服务模型进行了模拟测试和性能评价.
The IP QoS is becoming one of the core technologies of IP network, and the DiffServ model is receiving wide attention as an architecture for implementing services guarantees in the Internet. This paper first analyzed the IP QoS control mechanisms based on DiffServ, including the buffer management, queue schedule algorithms and congestion control mechanisms etc. Then a DiffServ simulation platform was built after the DiffServ model was modified in NS2 under Linux environment. The modified DiffServ model was simulated, and its performances were discussed.
