区分服务(Diffserv,DifferentiatedServices)是在Internet上提供QoS保证的一种很有前途的方法。区分服务实现简单,具有较好的扩展性和健壮性等特点。讨论了一种在Linux环境下实现Diffserv路由器的方法,并在网络实验床上做了性能测试,并进行了性能评估。测试结果表明该实现方法可以提供区分服务的能力。
Diffserv (Differentiated Services) is a promising way to provide QoS guarantees over the Internet. Differentiated services to achieve simple, with good scalability and robustness and other characteristics. A method to implement Diffserv router in Linux environment is discussed. The performance of the Diffserv router in the network experiment bed is tested and its performance is evaluated. Test results show that this implementation can provide the ability to distinguish between services.
