Embodiment 1

[0049] This embodiment provides a method for synchronizing protection switching protocols. In this embodiment, the configuration commands of the protection protocols are executed concurrently to complete the creation of the protection protocols on the active and standby units; the input information of the protocols is executed concurrently, and the Both protocols receive input information to execute decisions; the WTR state and DNR state are synchronized in real time to ensure the consistency of the state machine.

[0050] The method includes the following steps:

[0051] Step S202: The configuration command of the protection protocol is sent to the active and standby units where the protection protocol is located, and each completes the configuration of the protection protocol;

[0052] Step S204: The input information of the protection protocol is sent to the protection protocol on the master and backup units for storage.

[0053] Step S206: The protection protocol confirms...

Embodiment 2

[0069] This embodiment provides a protection switching protocol synchronization method. The synchronization method in this embodiment takes the state synchronization of the APS linear protection protocol on the multiplex section access side of the PTN equipment as an example in practice. image 3 is a schematic diagram of a protection switching protocol synchronization system according to an embodiment of the present invention, such as image 3 As shown, the management plane concurrently sends configuration commands to the APS protection protocol on the active and standby main control units to complete the configuration of the protection protocol, and the input of the switching control command is also issued by the management plane, and the APS protection protocol on the active and standby main control units receives and processes, The input information detected by the line card (alarm or receiving K1K2 bytes) is notified to the active and standby main control units, and the pr...

Embodiment 3

[0089] This embodiment provides a protection switching protocol synchronization method, Figure 4 is a flow chart of a protection switching protocol state synchronization method according to a preferred embodiment of the present invention, such as Figure 4 As shown, the method includes:

[0090] Step S401: start.

[0091] Step S402: Configure a protection protocol.

[0092] Step S403: The protection protocol receives the input information and saves the changes

[0093] Step S404: state machine processing.

[0094] Step S405: Calculate the decision output.

[0095] Step S406: Execute switching according to the output.

[0096] Step S407: Timing up processing.

Abstract

Disclosed are a method and a system for status synchronization of a protection switching protocol. The method comprises: an active unit and a standby unit receiving input information of the protection switching protocol at the same time; the active unit and the standby unit performing switching according to the input information and the protection switching protocol respectively; and the active unit and / or the standby unit performing status synchronization of the protection switching protocol according to an output state of the protection switching protocol after the switching operation. Through the present invention, the efficiency of the status synchronization of the protection switching protocol between the active unit and the standby unit is improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for synchronizing the state of a protection switching protocol. Background technique [0002] On the communication system equipment, there is often the protection of the board-level unit, and when there is a protocol running on the board, it involves how to ensure the synchronization of the protocol status running on the backup board and the main board, so that the switching of the board It has no effect on the operation of the protocol. The present invention discusses the synchronous processing for the protection switching protocol. [0003] The traditional processing method is to synchronize many information of the protection switching protocol on the main unit to the backup unit in real time, including input and output information, some intermediate variables of the state machine operation, and so on. Such processing results in a large amount of sync...
