Introduction and Application of Storage-Forwarding Under VxWorks

通信过程对时延敏感,通信数据需要实时的处理。VxWorks可靠的强实时性极好地满足了需求。本文在对VxWorks操作系统的网络接口实现方式深入解析、对硬件相关部分进行抽象分层的基础上,研究了高速存储转发系统的应用,提出一种优化存储转发效率的方法,对通信过程中的数据报存储、路由查表、数据报转发等技术作了全面的优化设计,并通过模拟测试对效率进行了定量分析,为嵌入式系统在高速存储转发的应用提供了一个可实现的方案。

Communication process is sensitive to the time delay and needs real-time processing. The reliable real-time character of VxWorks meets the needs. This paper analyzed the network inteiface Implementation methods of the VxWorks operating system, and studied the application of high-speed storage-forwarding system basing on the abstract stratification of hardware. By using VxWorks, this paper introduces an optimized method of storage-forwarding, and comprehensive technical optimizations are implemented in data storage, routing table look-up, data transmit. The paper also gives the quantitative analysis on the efficiency using simulation tests, which can be used on storage-forwarding system under embedded system.
