Embodiment Construction

[0030] The present invention adds a routing device to the existing network structure, and the routing device can select the content billing board of the corresponding service gateway for session connection according to the user's session request. When a single board fails, the routing device can perform fast The switch will neither make the user feel abnormal, but also ensure the security of the session data. The present invention introduces the concept of a logical standby board. By arranging multiple IPs on a single board, one single board can be used as a backup board for multiple host single boards. When a single board fails, the routing device will select a suitable IP To take over the service, thereby reducing the redundancy of the standby board.

[0031] Such as figure 1 As shown, it is a structural schematic diagram of the hot standby maintenance system of the present invention. In the figure, the hot standby maintenance system includes the following components: a net...

Abstract

The invention discloses a banked maintenance system, which comprises the following parts: network switch-in mode, business disposal veneer, route and alternate veneer. The banked maintaining method comprises the following steps: selecting network segment according parameter through route; judging whether the conversation is established; sending request to business disposal veneer if yes; building new conversation if not; building connection; sending request to business disposal veneer; disposing the business disposal veneer in the alternate veneer synchronously. The invention also provides accident switching method, which is characterized by the following: proceeding heartbeat detection for business disposal veneer and alternate veneer through route; switching the request into alternate veneer when detecting the interrupted heartbeat; disposing the request through alternate veneer.

Description

technical field [0001] The invention relates to a hot backup maintenance system and a method for hot backup maintenance and failover, in particular to a system for implementing dual-machine hot backup maintenance by means of state maintenance through a routing module, and using the system for hot backup maintenance and fault switching method for switching. Background technique [0002] With the construction of a new generation of wireless networks, the number of users using mobile data services is increasing rapidly. The new generation of wireless networks can provide high-speed wireless access for these mobile users. On the basis of this high-speed wireless access network, Many data services can also be carried out, such as WAP / HTTP browsing, multimedia messaging, download services, mail services, streaming media services, etc. For these data services, operators provide a variety of paid services, which are very important for the security of data services. The requirements...
