摘要
针对在一条物理链路中断的情况下部分用户不能访问智能双IP双线服务的缺点,提出了一种基于地址重写的智能双IP双线服务架构.新架构包括状态监测模块和地址重写模块,使之协同工作,当一条链路发生故障时,将流量转移到另外一条链路,当链路恢复正常时,将流量切换回正常路径,实现用户透明访问和不间断服务.测试在一条链路异常的情况下用户能否正常访问基于地址重写的智能双IP双线服务,结果表明新架构能够提高智能双IP双线服务的可用性.
Aiming at the shortcoming that some users can not access the intelligent dual-IP dual-line service when one line is down,an intelligent dual-IP dual-line service based on address rewriting is proposed.The new architecture has two modules:state monitoring and address rewriting that works together.When one line fails,the flow is transfered to the other line.When the line is restored,it switches the flow back.Therefore,the access is transparent with uninterrupted service.We test the intelligent dual-IP dual-line service based on the address rewriting when one line is down.The results show that the new architecture can improve the availability of the intelligent dual-IP dual-line service.
