Research and Implementation of Dual-stack Web Service Architecture Based on Intelligent DNS and Reverse Proxy Technology

摘要

In order to reduce the implementation cost and difficulty of providing WEB service based on IPv6 protocol, and to take full advantage of multi-export links, this paper designs a WEB service framework supporting IPv4/IPv6 by combining intelligent DNS and reverse proxy technology aiming at the environment of multi-export links in university network. Based on open source software BIND and Nginx, this paper proposes and implements a WEB service scheme combining intelligent DNS and reverse proxy technology. Practical application shows that the framework we proposed is capable of improving the speed of users accessing campus network WEB services in the access link network, reverse proxy effectively reduces the load of WEB service. The framework is based on open source architecture, which can be implemented without the modification of existing networks and WEB applications. On the basis of reducing the implementation cost, the advantage of multi export links can be exploited. The scheme can be deployed in other universities or similar network environments only by modifying configuration files.
