Embodiment Construction

[0046] The main purpose of the present invention is to provide a method for restarting and recovering EPL services, which determines the recovery strategy for EPL services after restarting when node control planes are restarted during the EPL service bandwidth adjustment process. Business-related configuration information is restored through the data information saved in the local database before the restart during the restart recovery process.

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation examples.

[0048] figure 1 It is a flowchart of the method of the present invention, as shown in the figure, the method of the present invention specifically includes the following steps:

[0049] Step 1. Save the EPL service information to the local database at key points before restarting, including the dynamic configuration information and service operation status information of each lay...

Abstract

The invention discloses control plane restarting recovery method and device during the EPL (Ethernet Private Line) service bandwidth control process in an automatically switched optical network. The method has the main technical steps of: (1) storing EPL business information comprising the dynamic configuration information of each layer of EPL service and service state information in a local database at a key point before restarting a control plane; (2) reading the stored EPL service information comprising the information of unfinished service before restarting from the local database after restarting, generating local service information according to the read EPL service information, and recovering the service states of an EPL layer, a VCAT (Virtual Concatenation) layer and a VC4 (Virtual Container) layer in sequence from top to bottom; and (3) recovering the connections of the EPL layer, the VCAT layer and the VC4 layer in sequence from top to bottom, and continuing the service bandwidth control operations of each layer before restarting. In the invention, a unified recovery policy from top to bottom is adopted after restarting.

Description

technical field [0001] The invention belongs to the technical field of intelligent optical networks, and in particular relates to an EPL (Ethernet Private Line, Ethernet dedicated line) service bandwidth adjustment process, ASON (Automatically Switched Optical Network, Automatically Switched Optical Network) node control plane restarts, after the restart, EPL services and The method and device for restoring service layer business thereof. Background technique [0002] Control plane restart refers to the process of restarting and restoring configuration information of control plane components. During the control plane restart recovery process, all configuration data before the restart needs to be restored. These configuration data include static configuration data and dynamic configuration data of components. [0003] The static configuration data of components are initialization configuration parameters, and usually these configuration parameters do not change during the r...
