Embodiment 1

[0028] see image 3 , the present embodiment provides a method for synchronizing information between primary and backup devices, the method comprising the following steps:

[0029] Step S302, the active device and the backup device establish a synchronization channel, wherein the synchronization channel includes a device-level channel and a sub-card-level channel; the sub-card-level channel transmits an information synchronization data message, and the main device and the backup device establish the synchronization channel through an information synchronization control message. sub-card-level channel;

[0030] The active device and the standby device can establish a synchronous channel in the following ways:

[0031] 1) The master device negotiates with the backup device to establish a device-level channel according to the configured address and port of the backup device, and the device-level channel is used to transmit signaling and synchronization information between the ma...

Embodiment 2

[0045] The difference between this embodiment and Embodiment 1 is that the synchronization channels in Embodiment 1 include device-level channels and sub-card-level channels, while the synchronization channels in this embodiment include device-level channels and backup group-level channels; The backup device establishes the backup group-level channel through the information synchronization control message; correspondingly, this embodiment uses the backup group-level channel to transmit the information synchronization data message; for example, after the master device encapsulates the user information into an information synchronization data message, Group-level channels are sent to the standby device;

[0046] Based on this, the channel encapsulation information includes the address and port number of the backup group-level channel.

[0047] When the backup group-level channel is established, the information synchronization control message carries the address and port number o...

Embodiment 3

[0051] This embodiment provides a method for synchronizing information between master and backup devices. The method uses figure 2 The shown BRAS dual-system hot backup networking structure is used as an example to illustrate. In order to better explain the operation process of information synchronization, see Figure 4 , the main and backup devices in this embodiment are respectively provided with the following modules:

[0052] The equipment management module 42 is responsible for maintaining the information maintenance between the two active and standby BRASs, such as the establishment of a synchronous channel;

[0053] An information synchronization module 44 is responsible for synchronously sending and receiving user information between the active and standby BRAS devices;

[0054] The backup group management module 46 is responsible for the maintenance of the backup group unit, such as active and standby selection, abnormal detection, and information channel between th...

Abstract

The invention discloses a method for synchronizing information between master equipment and standby equipment and a server. The method comprises the following steps that: the master equipment and the standby equipment establish a synchronization channel which comprises an equipment level channel, a subcard level channel and a backup set level channel on the subcard; the master equipment determines that user information needs to be synchronized, determines the corresponding subcard level channel or the backup set level channel according to the backup set where a user is, encapsulates synchronization information according to an address and a port corresponding to the subcard level channel or the backup set level channel, and transmits the encapsulated synchronization information to the standby equipment through the subcard level channel or the backup set level channel; the standby equipment analyzes the synchronization information to acquire the address and the port and forwards the synchronization information to the subcard corresponding to the port; and the subcard processes the synchronization information. Due to the method, the problem of higher load of a main control unit is solved; the mode is not limited by the performance bottleneck of the main control unit; and reliable guarantee is provided for the switching between the master equipment and the standby equipment.

Description

technical field [0001] The present invention relates to the communication field, in particular to an information synchronization method and server between master and backup devices. Background technique [0002] The service control layer of the broadband metropolitan area network is a unique layer where the service access network connects to the core switching network. The equipment that plays an important role is BRAS (Broadband Remote Access Server, Broadband Remote Access Server), which is mainly responsible for service access control and User management features. With the demand for high-quality assurance of services provided by the network, higher requirements are placed on the performance and reliability of BRAS products at the service control layer. In order to ensure smooth service, BRAS dual-system hot backup is usually used. [0003] like figure 1 The schematic diagram of the BRAS dual-system hot backup network structure is shown, in which CR (Server Router, serv...
