Method for selecting master clock based on PTP (Picture Transfer Protocol) and link quality, slave clock and system

Abstract

The invention relates to a method for selecting a master clock based on a PTP (Picture Transfer Protocol) and link quality, a slave clock and a system. The method comprises the following steps of: configuring a link quality selection strategy according to a link quality index, wherein the link quality index comprises link packet loss rate, delay jitter and/or link delay; and selecting a target master clock according to the configured link quality selection strategy. In the method for selecting a master clock based on a PTP (Picture Transfer Protocol) and link quality, the slave clock and the system, a user configures the link quality selection strategy (mainly comprising the indexes of link packet loss rate, the delay jitter and/or the link delay and the like), and the target master clock is selected according to the user configuring link quality selection strategy by combining with the PTP, which not only satisfies the actual selection demands of the user, but also improves multiselectivity and flexibility when the master clock is acquired and solves the problem that the master clock can not be selected when the master clock in the traditional PTN (Packet Transport Network) does not send a notice message.

AI Technical Summary

Benefits of technology

This technology uses certain rules for selecting one timepiece from another called primary timer. These rules help optimize communication between two devices - they are connected through specific links like packets lost over wireless networks. By combining these techniques with different types of data transmission systems such as TCP/IP, it can improve network performance without sending too many unwanted messages at once.

Problems solved by technology

This technical problem addressed in this patented text relates to improving precision clock accuracy during communication over long distances without increasing complexity due to the lack of coordination among different sources. Current methods involve selecting one master clock per second periodically instead of continuously choosing another master clock every few seconds.
