Portal protocol - based network access control system combined with specific projects in the internship switch product development , networking mode, Portal authentication switch and Implementation of through Portal authentication technology , in order to achieve user access to the network for control purposes. The papers from the security and stability of the network in the traditional networking environment , this paper introduces the basic message structure of the Portal protocol and the realization of the principle of the Portal authentication technology , and analysis Portal authentication with existing 802.1x, PPPoE authentication technology than under the Portal authentication technology advantage , and thus the the Portal protocol - based network access control system . The Portal certification that Web Authentication is a way to control the user access to network resources . Since the network was born , authentication , authorization, and accounting system (AAA) on the basis of their operations . The use of all kinds of resources in the network requires authentication , authorization and accounting process management , the Portal authentication technology to provide flexible access control mechanism , simply through HTTP page to receive a user name and password entered by the user can complete the certification process , not the need for special client software , but also can provide protection of critical network data entry . Papers of the Portal authentication technology systems analysis , combined with the practical application of common networking structure initiates an authentication request from the user to start , highlights check user information message interaction between Portal server and switch equipment , as well as Portal server unreachable thus affecting user network access problems , Portal will be taken to cancel the network authentication mechanism to ensure that the user's network business , Portal user information synchronization technology there is force to protect the user does not appear for a long time can not be downline accident . Portal extended functionality will provide more reliable access control , can greatly enhance the security of the terminal . Finally , from the perspective of project development and molding project unit testing and system testing , and gives a solution for the problems encountered in the test ,
