路由器如何在保证转发性能的前提下提供网络安全保证已经成为当前的研究热点。介绍了基于IXP1200网络处理器的安全路由器的设计和实现方案。该系统在网络处理器处理分组快速灵活的特点上集成了防火墙、带宽处理和策略处理等功能,在保证系统高度安全性的同时,还保证了转发性能。
How routers provide network security assurance under the premise of ensuring the forwarding performance has become the current research hotspot. This paper introduces the design and realization scheme of security router based on IXP1200 network processor. The system integrates the functions of firewall, bandwidth processing and policy processing in the fast and flexible processing of packets by the network processor, and ensures the high security of the system while ensuring the forwarding performance.
