基于网络处理器的服务质量控制

Control of QoS Based on Network Processor

网络处理器以其优异的性价比和高度的灵活性成为目前路由器中实现服务质量控制的最佳硬件选择。首先简要描述了区分服务机制,然后对其微块划分进行了分析。最后,基于Intel公司IXP2400网络处理器的硬件特征对数据存储模块和服务质量控制处理流程做了相应设计,有效实现了基于IXP2400的服务质量控制。

Network Processor becomes the best choice for reuters realizing quality of service at the present time, by reason of its excellent cost performance and flexibility. This article analyses DiflServ mechanism and its microblock partition. Based on the hardware feature of IXP2400, it designs the storage and flow of data for quality of service, and implements the control of QoS based on IXP2400.
