摘要
由于传统IPSecVPN网关面临新业务计算能力的困难,提出了多核系统系统下的IPSecVPN网关的实现方法。在Linux系统下通过对单处理器系统的IPSec VPN网关的报文处理流程的改进,实现了多核系统下的IPSec VPN网关,再通过多处理器间负载均衡和多核软件可执行级代码兼容性改进,进一步提高了多核系统下IPSec VPN网关的处理能力。最终测试结果表明,不仅在双核系统、四核系统上获得极高性能的提升,而且实现了可执行级代码的兼容性,并根据测试结果,在技术领域首次提出多核系统性能边际效益递减的规律。
Because of many difficulties to traditional IPSec VPN gateway,implementation of IPSec VPN gateway based on the multicore system is proposed.Firstly,the gateway based on single processor is realized in linux,and then by Load balancing among processors and transformation of executable code-level compatibility,processing capacity of IPSec VPN gateway based on multi-core system is further enhanced.Final test shows that very high performance of the IPSec VPN gateway based on dual-core systems and quad-core system is acquired,and the executable code-level compatibility is successfully achieved.According to test results,the law of diminishing marginal benefit is first proposed in the technical field of multi-core system.
