Data backup transmission processing method, device and system

Abstract

The embodiment of the invention provides a data backup transmission processing method, device and system. The method comprises the steps of: transmitting control information through a first channel between a main MPU (Micro Processing Unit) of master equipment and a standby MPU of standby equipment; transmitting data backup information through a second channel between at least one master single-board and at least one standby single-board; establishing the second channel through the following modes: obtaining master single-board information of the master equipment by the master equipment and obtaining standby single-board information of the standby equipment through the first channel; and establishing the second channel between the at least one master single-board and the at least one standby single-board by the master equipment according to the master single-board information and the standby single-board information. In the embodiment of the invention, control information is transmitted through the first channel, backup data information is transmitted through the second channel, therefore, data information with huge data volume can be sent through the second channel; and control information is only processed by the MPUs, thus, the processing capacity to the MPUs is small, and the forwarding capacity of a gateway device is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a data backup transmission processing method, device, and system. Background technique [0002] SR (Service Router, SR for short) / MSCG (Multi-Service Control Gateway, MSCG for short), as a multi-service gateway device, assumes the function of connecting the preceding and the following in the network. The SR / MSCG is connected to the core network to realize the three-layer routing function; the SR / MSCG is connected to the aggregation layer to terminate the user's two-layer message and realize the user access function; and the SR / MSCG carries multiple networks such as triple play (Triple Play) Among them, Triple Play includes High Speed ​​Internet (HSI for short), Voice over IP (Voice over IP, VOIP for short), Internet Protocol Television (IPTV for short), etc. [0003] In order to ensure high reliability, the dual-machine backup function is impl...

Problems solved by technology

[0009] However, the data channel between the MPU and the LPU is usually small. When the amount of backup data is large, especially for value-added services, such as: Network Address Translation (NAT for short), session border controller (Session Border Controller, referred to as: SBC) and Deep Packet Inspection (Deep Packet Inspection, referred to as: DPI) business, the amount of backup data is very large, at this time the data channel between the MPU and LPU can not meet the bandwidth requirements, so The value-added service cannot realize the dual-machine backup solution, and may cause the key data between the MPU and the LPU to be lost due to channel congestion; and the backup data and control information are all processed by the MPU, and data backup requires a large amount of MPU processing capacity. This will affect the processing of key services by the MPU and reduce the forwarding capability of the MSCG.
