Operation maintenance system and method of network access device

Abstract

The embodiment of the invention provides an operation maintenance system and a method of a network access device. The system comprises an interface unit pull-out processing module for hiding user service table item information when a first interface unit is pulled out, and an interface unit insertion processing module for recovering the user service table items hided by the first interface unit pull-out processing module when in the insertion into a second interface unit and simulating the construction of the online process of a user. The embodiment of the invention further provides an operation maintenance method of the network access device. By the use of the embodiment of the invention, the functions of automatic hiding and automatic recovering the user service table item information when in hot swap of the interface units can be realized with lower arrangement cost, and the insensitivity of the terminal user to the interface unit replacement operation of the network access device can also be realized so as to lead the terminal user to be capable of automatically recovering the service without the need of re-dialing or re-starting a client end.

Description

technical field [0001] The present invention relates to the communication field, in particular to an operation and maintenance system and method for network access equipment. Background technique [0002] The BRAS device (Broadband Remote Access Server, Broadband Remote Access Server) is mainly used for access management of Internet users, and its functions mainly include user authentication, authorization, billing and so on. BRAS equipment uses a distributed system architecture to achieve high-specification and high-density user access, and usually includes a main control unit and an interface unit. The main control unit is used for centralized user management, and the interface unit is used for service forwarding and traffic access. Can refer to figure 1 . [0003] During business operation, if the interface unit fails, the interface unit needs to be replaced. Existing network devices generally support hot-swapping (hot-swapping) operations of interface units. The ser...

Problems solved by technology

The service configuration information of the interface unit can also be automatically restored, but if only the service configuration is restored, it cannot meet the requirements of end users (such as personal computers) not to be aware of network interruptions

End users also need to redial or even restart the device to restore the service, which causes problems with the operability and maintainability of the BRAS device: (1) When the interface unit is pulled out, according to the traditional processing flow, the user related to the interface unit Data loss (mainly including user service entry data); (2) When the interface unit is reinserted, because of the loss of user service entry information, the access user must redial, re-authenticate, authorize, and charge. This will cause users to clearly perceive network equipment failures and service interruptions, resulting in user complaints; (3) For PPPOE (Point to Point Protocol over Ethernet, point-to-point connection protocol on Ethernet) users, there are heartbeat messages, and the dial-up software can perceive And it can be manually redialed, the impact is relatively small

[0006] The problems of the above prior art are: (1) The cost of network deployment is high

(2) The solution is dependent on upstream and downstream equipment, and it is difficult to deploy applications on the live network

If the dual-system hot backup solution wants to achieve service switching in a short period of time, it usually needs to deploy fast detection protocols such as BFD / ETH OAM, but the downstream switches currently deployed rarely support such protocols
