【摘要】 在深入分析基于第四层交换的负载分担技术基础上,利用Intel IXP2400网络处理器高度灵活的可编程性和强大的网络数据包处理功能,设计了一套具有第四层包交换能力的负载分担系统。该系统在二层交换模块上,添加第四层交换式负载分担模块,并应用了“一次处理,多次交换”的第四层交换技术思想,大大加快了系统处理速率。同时基于网络处理器的技术优势,使得负载分担系统具有良好的可扩展性和实用性。更多还原

【Abstract】 Firstly this paper deeply analyzes the load balance technology based on fourth level interchange. Secondly a design scheme of load balancing system using IXP2400 network processor is put forward. The system realize fourth level switching and load balance module including basic second level switching module, and this technology idea:"Processing at the first time, Switching for the follow packet" is also introduced to system design, which make the operation speed improving greatly. Besides, due to using the network processors with extremely flexible programmable ability, the total system has the good extensibility and practicability.更多还原
