Design And Implementation Of Universal Network Mapping Strategy Management System

With the development of the network technology and the rapid growth of the Internet scale, the current Internet architecture is becoming more and more difficult to satisfy the requirements of the mobility and the security. Consequently, in recent years, a number of institutions begin to do deep research on the new network architectures. And the conception of universal network, which might support multi-services in a single network, and solve the problems of security, mobility and the connection of sensor network was put forwarded.In the meantime, with the application’s promoting of the network and the growing number of clients and the increasing variety of services, the differences among varied identities and the personal requirements result in different levels of requirements of the services. Furthermore, to standardize the utility of network and to ensure the security of the network information, it is necessary to identify the requests in the universal network. Therefore, we study the accessing control based on the universal network, and develop the policy management system to improve user experience and network efficiency.In this paper, firstly, based on the analyzing of the access control technology and the string matching technology of user access services, and according to the characteristics of the access mechanisms of users and services in the universal network, we proposed a mapping strategy management plan of universal network, with the combination of string matching mechanisms and access control mechanisms of universal network. According to this plan, the management and maintenance of strategy matching rules of the universal network could be realized by arranging corresponding strategy matching module in the network core equipment Identifiers Mapping Server and the Access Switch Router, respectively. Secondly, we discussed and realized the possibility of the realization of the strategy matching of user access services in the universal network by using regular expression and string matching method. Lastly, we tested the function and the performance of the strategy management system, and the results of the tests showed that this management system is a very efficient tool to manage service accessing of users in the universal network.
