IPC: H04L7/00
Filed: 2020-12-16
Abstract: Disclosed in embodiments of the present application is a message processing method. In the method, when obtaining a first message for clock synchronization, a first device may record a first timestamp, the first timestamp being used for indicating the moment when the first device obtains the first message. After obtaining the first message, the first device may determine, according to the first message, a port for forwarding the first message, and records a second timestamp, the second timestamp being used for indicating the moment when the first device determines the port. The first device may generate, according to the first message, a second message comprising the third timestamp, and send the second message to the second device, the third timestamp being determined according to the difference between the second timestamp and the first timestamp. The step of determining the port may be performed by a switching module in the first device, that is, the third timestamp may reflect the residence time of the first message in the switching module. Therefore, when a sink device performs clock synchronization, the packet delay variation introduced by the switching module can be removed, thereby improving the accuracy of clock synchronization.
