Abstract
本论文针对在使用IPSec网关时由于用户量不断增加、网络流量需求大的情况下所造成的时延、阻塞、吞吐量小等问题，分析了内核态IPSec解决方案处理流程中存在的不足，提出了基于DPDK在用户态实现IPSec网关的方法。针对传统方案处理开销大的问题提出利用思科的VPP作框架，DPDK作收包工具搭建平台实现数据包在用户态的处理。测试结果表明，基于DPDK的用户态IPSec解决方案与传统方案相比，性能得到了有效的提升。 This paper aims at the problems of delay, congestion, small throughput caused due to increasing users and more network traffic demand by using IPSec gateway, analyzes the shortcomings during the IPSec solution process, and puts forward the method of implementation of DPDK gateway based on IPSec in user space. Aiming at the problem of large overhead of traditional programs, we propose to build Cisco VPP as a platform and DPDK as a receiving packets tool to build data processing platform. The test results show that the performance of the IPSec solution of user space based on DPDK is improved effectively compared with the traditional solution.
