<p>A method, device and system for synchronizing data in a control session are disclosed. The method includes the following steps: after a control session/connection is reestablished, a second control session node receives a synchronization message from a first control session node; the second control session node synchronizes data according to the synchronized data carried in the synchronization message; after the control session/connection is reestablished, the first control node obtains local data, and sends the obtained data to the second control session node through a synchronization message, notifying the second control session node of synchronizing data. With the present invention, data is synchronized between the control session nodes, and the network error and even denial of service due to out-of-synchronization of the data between the session nodes are solved. In addition, the data can be synchronized after the session is steadily restarted; the control plane is separate from the data plane; and the robustness of the network is increased.</p> |
