IPv6下DiffServ在Linux中的设计与实现

QoS的研究目标是有效地为用户提供端到端的服务质量控制或保证,而IPv6不仅有效地解决了网络地址危机的问题,而且为提升网络服务质量(QoS)提供了更好的支持。剖析区分服务模型的数据流分类和PHB实现预定义标识流,同时分析Linux内核中的流控制机制。在Linux平台上利用流量控制工具集TC,对物理网络设备绑定CBQ队列、在队列上建立分类、为每个分类建立路由的过滤器,从而实现不同类数据流的区分和带宽保证。并对现有的队列、分类、过滤器和路由进行监视。实现表明,测试平台运行稳定,可以为QoS研究提供一个开发式的测试环境。

Design and Implementation of DiffServ on IPv6 Protocol under Linux

The goal of QoS is effective for users with end-to-end service quality control or assurances,and IPv6 is not only an effective solution to the network address of the crisis,but also for improving network quality of service(QoS) to provide better support.Analyzes the data flow classification of differentiated service model and identification PHB achieving predefined flow,and analysis of the Linux kernel in the flow control mechanisms.On the Linux platform using tool-set TC,the physical network equipment bundled CBQ queue,the queue in a classification,a classification for each routing filters,a different type of data flow and bandwidth distinction.And exist in the queue,classify,filter and routing surveillance.Achieve that stability testing platforms can provide QoS for the development of a test environment.
