Delay-constant PTP (peer to peer) signal protocol conversion system and implementation method thereof

Abstract

The embodiment of the invention provides a delay-constant PTP (peer to peer) signal protocol conversion system and implementation method thereof. The delay-constant PTP signal protocol conversion system further comprises a PTP signal protocol conversion device, wherein the PTP signal protocol conversion device mainly comprises a signal receiving module, a protocol conversion module and a signal transmitting module and is used for adding timestamps when a PTP signal protocol is converted and a PTP signal enters and departs from a protocol converter; the delay-constant PTP signal protocol conversion system comprises a first PTP signal protocol conversion device and a PTP signal receiving device; and the PTP signal receiving device is used for receiving a conversion protocol transmitted by the first PTP signal protocol conversion device and the PTP signal added with the timestamps, settling the delay time of a protocol conversion process and removing the delay time in a time synchronizing process.

Description

technical field [0001] The invention relates to the technical field of time communication, in particular to a PTP signal protocol conversion system with constant delay and an implementation method. Background technique [0002] With the continuous development of science and technology, all walks of life have higher and higher requirements for time synchronization, and research on time synchronization has been continuously carried out. At present, in the field of time synchronization, a more cutting-edge method is that the master clock transmits PTP signals to the slave clock through the Synchronous Digital Hierarchy (SDH). This method not only has high accuracy, but also can not be affected by SDH switching. [0003] However, the above-mentioned time synchronization method has a problem in communication technology that the PTP signal sent by the master clock adopts the Ethernet protocol. To enter SDH, it must be converted into a 2M protocol adapted to SDH. Similarly, when th...

Problems solved by technology

[0003] However, the above-mentioned time synchronization method has a problem in communication technology that the PTP signal sent by the master clock adopts the Ethernet protocol. To enter SDH, it must be converted into a 2M protocol adapted to SDH. Similarly, when the PTP signal leaves SDH and enters the slave clock, It is also necessary to reconvert the PTP signal of the 2M protocol to the Ethernet protocol

[0004] Therefore, if there is no protocol converter with short delay and constant, then the above-mentioned time synchronization technical solution cannot achieve the desired effect
