METHOD, DEVICE AND SYSTEM FOR DATA SYNCHRONIZATION OF A CONTROL SESSION

摘要

A method, a device and a system for data synchronization of a control session are disclosed. The method includes: after the control session/link is re-established, a second control session node receives a synchronization message sent from a first control session node. The second control session node makes synchronization data processing according to the synchronization data contained in the synchronization message. After the control session/link is re-established, the first control session node retrieves the locally stored data. The first control session node transmits the retrieved data to the second control session node in the synchronization message. The synchronization message is used to notify the second control session node to make synchronization data processing. The data synchronization between the control session nodes is implemented. The problem of network errors and denial of service because of the loss of data synchronization between session nodes is solved. The synchronization of data after the smooth resetting is achieved. The separation between the control plane and the data plane is implemented and the robustness of the network is improved.
