Node Clock Synchronization Planning Method in Mesh Network

Abstract

Disclosed is a planning method for node clock synchronization in a mesh network, which relates to the field of optical communications. The method comprises the steps of: establishing network data, performing domain division on a network so that each domain is provided therein with two available clock sources, and setting priority levels of network nodes and links; traversing the nodes in the domain, checking the clock status of the nodes, and calculating nodes having no master and / or standby clock sources by using domain as a unit: using a shortest path first SPF algorithm to calculate the master and / or standby clock path of each node, according to the calculated master and / or standby clock path, configuring the master and / or standby clock link of the node, and obtaining a clock master and / or standby clock source for each node. The present invention can achieve automatic planning of a clock synchronization network in a complicated mesh network, and can be used in network management or a node control plane algorithm, to achieve the purpose of automatically looking for available clock sources after clock interruption, thereby solving the problems of complexity, inaccuracy, etc. of manual planning.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a node clock synchronization planning method in a mesh network. Background technique [0002] The information transmission of optical network equipment needs to maintain clock synchronization. At present, the planning of the clock synchronization network is generally planned manually. In a ring network or a chain network, the clock synchronization source of each node can be easily planned according to the standard. However, when the network becomes more and more complex and a mesh network is formed, it is very difficult to plan node clock synchronization by manual planning, and it is not easy to judge whether the clock will form a loop under various circumstances, and whether the master and backup sources of the clock will Simultaneous interruption etc. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the above-men...
