摘要
VPN网关的实时处理能力是制约其性能的"瓶颈"问题之一。为此,提出了一种基于高速DSP的VPN安全网关的设计方法,并基于双TMS320C62芯片实现了宽带VPN安全网关。重点介绍了该服务器的总体架构、Linux内核与DSP之间的通讯机制以及VPN加/解密处理的实现方法。
The realtime performance is one top concern of VPN Gateway. In order to solve the problem, a novel approach to design VPN security gateway based on DSP was prsented . With dual TMS320C62x chips, a applicable broadband VPN Gateway has been implemented. The functional framework of the presented VPN gateway, the communication between Linux kernel and DSP,the implementation method for encryption algorithm, etc. were given in detail.
