Data synchronization method and device among forwarding boards

Abstract

The present invention relates to the communication field, and discloses a data synchronization method and device of a forwarding board, which are used to improve the execution efficiency of the data synchronization process and reduce communication overhead between boards. Data related information, and when the specified timing is reached, the information stored in each linked list node in the business data linked list is sequentially read to obtain the corresponding business data, and sent to the standby forwarding board for data synchronization. Due to the high access efficiency of the business data linked list, the real-time synchronization of business data is guaranteed between the main forwarding board and the standby forwarding board, and the smooth transition of the business is guaranteed when the main forwarding board and the standby forwarding board are switched. The service reliability of the communication equipment is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for synchronizing data between forwarding boards. Background technique [0002] In large-scale communication equipment, for reliability considerations, the important forwarding board is usually set as the main forwarding board [0003] The so-called forwarding board is the hardware where the module with transceiver function is located. Communication devices usually run services based on various communication protocols, and dynamic data will be generated when the services are in progress, for example, a dynamic multicast member table will be generated when multicast services are running, and MPLS (Multiple Protocol Label Switching, Multi-Protocol Label Switching, ) of VPLS (Virtual Private Lan Service, Virtual Private Local Area Service) produces Mac learning tables and the like. In order to ensure that the business process is not interrupted as much as possible or ...

AI Technical Summary

Problems solved by technology

[0004] Under the existing technology, the data used in the forwarding board is usually stored in the form of a database table. The data stored in the database table is very time-consuming to access, and every time a synchronization operation is performed, only all data can be synchronized. This further reduces the execution efficiency of the data synchronization process, especially when the communication bandwidth between forwarding boards is small or / and the amount of data to be synchronized is too large, this defect is more obvious, and in severe cases, it will also affect the forwarding board switching process implementation, thereby reducing the service reliability of communication equipment
