Embodiment Construction

[0035] The main point of the embodiment of the present invention is to use the restart type and restart delay parameters to effectively manage and control the restart of the ASON control node; the restart delay parameters are used to prepare for restart, which is beneficial to better maintain the consistency of the data of the control node itself.

[0036] The embodiment of the present invention adopts a more definite parameter control method, including the following steps:

[0037] When the user (or the management plane) requires the ASON control node to restart, it should bring the following parameters:

[0038] parameters

ASON node identification

Identify ASON nodes that need to be restarted

restart type (optional)

Abstract

The invention discloses a method for restarting a control node in an automatic switching optical network, which comprises the following processes: a restarting order is received by the control node and a restarting parameter in the restarting order is detected; the whole control node is restarted if a restarting type is not obtained in the restarting parameter; relevant modules and upper layer modules are restarted according to the restarting type and a module depending relationship table if the restarting type is contained in the restarting parameter. A time delay parameter can also be contained in the restarting parameter for preparing restarting. The invention solves the problem of too much impact on the system when the whole node is restarted in the condition that only parts of the modules (protocols) are necessary to be restarted. And the invention preferably maintains the data consistency of the control node.

Description

technical field [0001] The invention relates to the field of automatic switching optical networks, in particular to a method for restarting control nodes of automatic switching optical networks. Background technique [0002] In the field of Automatically Switched Optical Network (ASON, commonly known as intelligent optical network), the ASON control node (that is, the so-called smart device) is responsible for the connection management and control of the entire network, and more processing protocols are running on it. . During the operation of the control node, a serious error may occur in some part and needs to be restarted; or the user has modified some important parameters, and some modules (protocols) need to be restarted to make the new parameters take effect. How to smoothly handle the restart of nodes, avoid the excessive impact of restart processing on the system, and effectively ensure the stability and robustness of the system has become a more complicated and imp...
