基于网络处理器的QoS策略应用网关

A Policy-Based QoS Applications Gateway Using Network Processors

网络处理器 (NetworkProcessor,简称NP)可以满足新的业务与协议带来的网络处理高速度与灵活性的要求 .改造核心网络以适应新的协议与提供新的服务如服务质量 (QualityofService ,简称QoS)、控制安全 (Security)等 ,并实施新的基于策略的网络管理 (Policy -BasedNetworkManagement,简称PBNM)是非常困难的 ,基于网络处理器的QoS策略应用网关可以作为一种从边缘到全网的过渡方案 ,在QoS与PBNM广泛实施之前 ,可以实现对现有的网络实施QoS策略管理 ,优化网络性能 。

Network processors can provide the high performance and scalability required by the implementing of the new services and protocols. Adapting the core networks to the new protocols, providing new services such as Quality of Service(QoS), network security, etc. and realizing Policy-Based Network Management(PBNM) are very difficult. Before the broad realization of QoS and PBNM on the internet, the policy-based QoS applications using network processors can work as a transition method to implement QoS and policy-based network management on the borders of the networks and improve the performance and efficiency of today's networks.
