The invention discloses a processing method of a PTP (Precision Time Protocol) message and an SOC for solving the problems of low efficiency and big resource occupation quantity in the prior art. The processing method of the PTP message comprises the steps of adding a receiving timestamp for a message based on current time when the message is received; applying for a storage identifier for the PTP message when the message is a PTP message; and after adding the storage identifier to a PTP message storage queue, finishing clock synchronization with a PTP message transmitting end based on the receiving timestamp and transmitting timestamp of the PTP message. Therefore, as the PTP message is added in the PTP message storage queue, the PTP message and a non-PTP message can be distinguished, a method for calling a processing function to process the PTP message is unnecessary, the PTP message in the PTP message storage queue can be directly processed, the processing link of the PTP message is reduced, the processing efficiency of the PTP message is increased, and resources occupied by calling the processing function are saved.
Description
technical field [0001] The invention relates to the technical field of information processing, in particular to a PTP message processing method and SOC. Background technique [0002] The Precision Time Protocol (PTP) is a protocol for time and frequency synchronization of standard Ethernet terminal equipment, also known as IEEE 1588, or 1588 for short. In the PTP clock synchronization system (that is, the PTP domain), there is one and only one synchronous clock, and all terminal devices in the PTP domain are synchronized with this clock. Among them, the node that issues the synchronous clock in the PTP domain is the master node, and the node that receives the synchronous clock is the slave node. The master node and the slave node can use the 1588 clock synchronization algorithm to realize clock synchronization by exchanging PTP messages. [0003] In the prior art, when a node in the PTP domain receives a PTP message, software adds a receiving time stamp to the PTP message....
