Abstract:

In current multihomed network service deployment methods, the service access route is unreachable due to the changed ISP network addresses, DNS configuration, or other factors. Aiming at this drawback, the paper proposes a strategy of multihomed network service deployment based on strategy DNS and HTTP Proxy. The proposed strategy installs HTTP Proxy server on each ISP output and works with DNS server to perform joint deployment. The strategy is analyzed theoretically and the deployment method is described in detail. Case analysis and effect evaluation demonstrate that the proposed strategy can greatly improve the speed and quality of internet user access of the campus network and enterprise network information resource services, without changing the network topology and increasing no more investment basically. It is concluded that the strategy solve the problem that the route is unreachable in the traditional way.
