IP clock packet processing method, equipment and system

Abstract

The embodiment of the invention relates to a method, a device and a system for processing IP clock messages. The method comprises: acquiring timestamp information which is obtained by analyzing the IP clock messages through a network processor in an analysis mode corresponding to the message type of the received IP clock messages and corresponds to the IP clock messages; and acquiring clock adjustment reference information which is used by a master control unit to adjust local timestamp information according to the timestamp information and the local timestamp information. The device comprises a first receiving module and a first processing module, wherein the first receiving module is used for acquiring the timestamp information which is obtained by analyzing the received IP clock messages through the network processor and corresponds to the IP clock messages; and the first processing module is used for acquiring the clock adjustment reference information which is used for the mastercontrol unit to adjust a clock according to the timestamp information and the local timestamp information. The method, the device and the system can flexibly analyze complex IP clock messages which are newly expanded and packaged by protocols by adoption of the network processor to analyze the IP clock messages.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless communication, and in particular to a method, device and system for processing IP clock messages. Background technique [0002] With the continuous development of the Internet Protocol (Internet Protocol, hereinafter referred to as: IP) packet switching network, the synchronization problem of the IP clock has become increasingly prominent. What is transmitted in the digital switching system is the discrete pulse signal obtained by encoding the information. If the IP clocks between the two digital switching devices are inconsistent, the loss or repetition of symbols will occur in the buffer memory of the digital switching system, resulting in Slip impairments occur in the transmitted bit stream. For example, when traditional fixed-line Time Division Multiplex (TDM) services are carried over Ethernet, if the IP clocks at both ends of the bearer network are inconsistent, c...
