Method and system for improving ieee1588 unicast negotiation mechanism

Abstract

The invention discloses an improvement method and system for an IEEE1588 unicast negotiation mechanism. The method comprises the steps of encoding the unicast negotiation information content, and on the basis of encoded unicast negotiation information, establishing connection and conducting unicast communication on a master clock device and a slave clock device. According to the improvement method and system, the technical problems that due to the fact that in the prior art, an existing unicast negotiation system is complex, not high in reliability and lower in efficiency, the processing capacity of the master clock device and the slave clock device is affected, the extra network bandwidth is increased, and synchronous precision of the master clock and the slave clock is affected are solved, and the improvement method and system for the IEEE1588 unicast negotiation mechanism has the advantages that the unicast negotiation mechanism is simple and high in efficiency, the processing capacity of the master clock device is improved, the network bandwidth is saved, and the function of the unicast negotiation mechanism is expanded.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method and system for improving an IEEE1588 unicast negotiation mechanism. Background technique [0002] IEEE 1588 is the Precision Time Synchronization Protocol (referred to as PTP) standard for network measurement and control systems, and the standard has been developed to version v2. The PTP protocol adopts a master-slave synchronization method, and provides a clock synchronization function between the master and slave devices based on the time stamp of sending and receiving network data packets. The clock synchronization accuracy mainly depends on the accuracy of the time stamp, and the accuracy of the time stamp has a lot to do with the location where the system obtains the time stamp. There are generally three locations for obtaining timestamps: the hardware layer, the driver layer, and the application layer. The closer to the physical layer, the higher th...
