针对目前常用的多宿主网络服务部署方法中存在的由于ISP网络地址集的变化或DNS配置等因素会造成服务访问路由不可达的不足,提出了一种基于策略DNS与HTTP Proxy在多宿主网络中服务的部署策略,在各ISP出口安装HTTP Proxy服务器,配合策略DNS服务进行联合部署。从理论上对该策略进行了分析,并对部署方法进行了详细阐述。通过实例分析及效果测量,证实了在不改变网络拓扑、基本不增加投入的情况下,通过该策略可大幅度提高校园网或企业网信息资源服务的互联网用户访问速度和访问质量,并解决了传统方式中路由不可达的问题。
Aiming at the shortcomings of the commonly used multi-homed network service deployment methods such as the changes of ISP network address set or DNS configuration and other factors, this paper proposes a policy-based DNS and HTTP Proxy in multi-homed networks Service deployment strategy, install the HTTP Proxy server at each ISP exit, and cooperate with the strategy DNS service for joint deployment. This strategy is theoretically analyzed and the deployment method is described in detail. Through the example analysis and effect measurement, it is confirmed that without changing the network topology and basically without increasing the input, this strategy can greatly improve the Internet user access speed and access quality of the campus network or enterprise network information resource service and solve the problem Routing unreachable in the traditional way.
