摘要: 为了在无线网络中保证实时多媒体业务的服务质量(QoS),基于IPv6在无线局域网中设计并实现了差分QoS测试平台,实验测试各种支持QoS调度策略。测试平台核心部件为实现差分QoS调度的IPv6路由器。路由器由Linux操作系统来实现,采用可加载内核模块编程,使用Netfilter中钩子函数截获网络数据包,根据业务的不同优先级进行调度,合理分配网络资源,保证实时业务的服务质量。在此平台上,进行了多媒体业务差分QoS的演示和测试。实验表明,测试平台运行稳定,可以为QoS研究提供一个开放式开发测试环境。

Abstract: To guarantee QoS of real-time multimedia traffic networks in wireless network, designed and implemented a QoS differentiation IPv6 test-bed. Test-bed can implement and test many QoS scheduling scheme and its key component is IPv6 Router in which QoS differentiation scheduling runs. Scheduling is implemented by Loadable Kernel Module of Linux which captures packets via hook of NetFilter and forwards them according priorities. Given higher priority, signaling and real-time traffic will get better QoS. Test-bed works well as an open development environment for QoS research.

Key words: Linux, IPv6, QoS, test-bed
