Design And Implementation Of Dual-system Hot Backup Based On Portal

Today, China's Internet has made in the overall environment, popularization and development of Internet applications hot industry made great progress, the network has penetrated into every aspect of people's lives, followed by network complexity and diversit y. For operators, to provide customers with a variety of broadband access services, when the authentication system as the first step of broadband access, but also access to the network as a key step to achieve good operation and management; for users, network services quality and safety are important points of user attention; therefore, how to efficiently operate and manage network resources has become the most important issue that must be addressed operators. This paper proposes a certification system based on hot standby scheme Portal of two planes, the subject is one of the items I am in Hangzhou H3 C is involved in practice, the system not only provides the Portal authentication function, the most important It is also provided hot standby feature service level.1. This paper first in-depth analysis of the current status of the development of access authentication system and some of the practical problems faced by: poor reliabilit y standalone Portal authentication system, when the system fails, the user can no longer access the network. On the key business points, Portal single bound to reveal the many drawbacks, may cause the user experience is poor, even bring huge economic losses.2. On the basis of this proposed scheme, study and analyze a typical dual system of networking model, we give a detailed functional requirements and performance requirements, and feasibility analysis.3. Secondly, given the overall design of the system, according to business functions into the system kernel modules Portal and Portal module, and were described in the detailed design of the interior of each module and implementation process.4. Finally, the build system test environment, writing test cases, the system is fully functio na l testing and performance testing. After verification of the test session, the prototype system functionality and performance has basical y reached the expected goal, to meet the overall demand for broadband operators access systems.5. In view of the focus on the business of the system-level backup, the user experience functionality certification system should be improved, such as: Portal no perception authentication, Portal radio and other functions. These functions can be deployed on Portal hot standby certification system, in Chapter VI of this paper gives a detailed system improvements direction.The system can help operators to provide users with stable and reliable network services, namely, when the master device has business fails, the backup device will immediately take over the Portal business, continue to the new Portal user access certification, and to ensure that all on-line Portal user data communication is normal, this real-time effective protection of the Portal authentication when the system fails, the user's online experience is not affected, thereby improving the reliability and quality of service network system.
