Example Embodiment

[0048] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0049] See figure 1 , An embodiment of the communication system for master / backup switching of the present invention is proposed, including: a control plane single board 10, an interface board 20, and at least two media plane boards 30; among them, two processing on different media plane boards 30 The units form an active-standby group, in which one processing unit is the first processing unit, and the other processing unit is the second processing unit;

[0050] The control plane single board 10 is used to detect the current status of the first processing unit as the main processing unit and the second processing unit as the backup processing unit in the active and standby group; and when the current status of the first processing unit is abnormal, Update the state of the first processing unit to an abnormal state i...

Abstract

The invention discloses a master-slave switching communication system and a master-slave switching communication method. The method comprises the following steps that: a control plane veneer detects states of a master first processing unit and a slave second processing unit of a master-slave set; when the first processing unit is currently abnormal, the control plane veneer updates the state of the first processing unit into an abnormal state in a master-slave set information table maintained by the control plane veneer and sends a master-slave switching command and a state updating command to the second processing unit; according to the state updating command, the second processing unit updates the state of the first processing unit into the abnormal state in master-slave set information maintained by the second processing unit; and according to the master-slave switching command, a slave example linked list is operated and is added into a second master example linked list to participate in service dispatching. According to the master-slave switching communication system and the master-slave switching communication method which are provided by the invention, the backup and the load sharing of service data are implemented, the phenomenon of interruption of a service is effectively prevented, and the resource utilization rate of the system is improved on the basis of ensuring the reliability of the communication system.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication system and a communication method for active / standby switching. Background technique [0002] In the existing communication system, in order to make the system work stably at high speed. Usually it is necessary to back up important boards, that is, the boards are respectively set as the main board and the backup board. When the master board fails, the system quickly switches to the backup board to work. [0003] Currently, most backup implementations are 1+1 or N+1 backup methods. In the 1+1 backup mode, the master board and the backup board need to run the same program, and the master board synchronizes data with the backup board through synchronous operation; when the master board fails or is switched over, the backup board continues to work , which can prevent the occurrence of business interruption and ensure the reliability of the system, but ...
