摘要: 多媒体业务的出现,使得传统的公平服务的服务质量已不能满足此类业务实时性要求。DiffServ机制通过设置优先级和边缘监管实现了对不同业务的区分对待。分类器是DiffServ机制实现的一个必要部件。该四元组分类器在一种通用网络处理器IXP2800上实现,并在Intel的仿真环境workbench下验证通过。

Abstract: With the advent of multimedia service, the traditional fair traffic service mode can no longer satisfy the need of their quality of service (QoS). DiffServ scheme can differentiate different applications by setting priority for each flow and policing traffic at the edge of network. Classifier is one of the parts in implementation of DiffServ. This complement of DiffServ four-tuple classifier is based on a general-purpose network processor IXP2800 and has been tested under workbench - Intel simulation environment.
