Abstract

The invention provides a data synchronization method and device of a distributed system. The method comprises the following steps: when a sending end creates data items, sequentially allocating a sequence number to each created data item; processing the sequence number corresponding to each changed data item; and sending a synchronous message comprising the processed sequence number information to a receiving end. According to the method, the deleted information items are expressed by information items which are not deleted, and the possibility that the memory is exhausted due to the insufficient communication capability is avoided.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for synchronizing distributed system data. Background technique [0002] Today's network devices are generally distributed devices with separate data forwarding and control functions. The main control card responsible for the control function interacts with other devices to generate a huge amount of routing information, and sends the routing information to the Data forwarding is realized on each line card. [0003] The traditional synchronization method is to directly convert these routing information into internal communication messages on the main control card and send them to each line card. This synchronization method will cause serious problems in some occasions. For example, the external routing information fluctuates rapidly, which causes the internal communication messages of the device to be sent to each line card too late, resulting in a back...
