基于FPGA的VPN网关设计方案研究

Research on FPGA-based VPN Security Gateway Design

提出了一种基于FPGA的高速VPN网关的设计方案。它的特点是用FPGA方式完成VPN网关的实时处理,而将通用处理机置于数据通路之外,完成系统配置和管理功能。这种构架的VPN实时性好,可以线速处理IP包,而且易于管理。

A novel approach to design FPGA-based VPN is proposed. It uses several FPGAs to implement the VPN functions and place a general-purpose processor outside the data path to do the system management and configuration function.
