Problems solved by technology

[0013] The present invention solves the problem that the current 1PPS+ToD time interface needs to be configured and forced to participate in IEEE1588v2 source selection. The configuration workload is high and the requirements are high. Because the source selection cannot be performed in a unified way, it is easy to cause clock tracking to form a loop.

Embodiment Construction

[0038] An embodiment of the present invention provides a method for processing clock information, the flow of which is as follows figure 1 shown, including the following steps:

[0039] Step 101: Receive a message defined by the first time interface protocol, the message includes clock information, and the clock information is defined by the second time interface protocol to represent the time information corresponding to the time information transmitted according to the first time interface protocol clock, the first time interface protocol and the second time interface protocol are different protocols;

[0040] Step 103, decapsulating the message to obtain the clock information;

[0041] Step 105, according to the second time interface protocol, use the clock information to select a source.

[0042] Further, the first time interface protocol includes a 1PPS+TOD interface protocol, and messages defined by 1PPS+TOD include TOD time information messages.

[0043] Further, the...

Abstract

The invention discloses a method, device and system for processing clock information. The method comprises the following steps of: receiving a message defined by a first time interface protocol, wherein the message comprises clock information which is defined by a second time interface protocol and used for indicating a clock corresponding to the time information transmitted by the first time interface protocol, and the first time interface protocol is different from the second time interface protocol; performing de-capsulation on the message to obtain the time information; and selecting a source by using the time information according to the second time interface protocol. By adopting the embodiment of the invention, the configuration work amount and the configuration technical requirement can be lowered, and the probability of clock source tracking looping is lowered by performing uniform source selection on clocks including the clock.

Description

technical field [0001] The invention relates to the field of data communication, in particular to clock information processing. Background technique [0002] IP (Internet Protocol) is the development trend of future networks and services. A transport network based on SDH (Synchronous Digital Hierarchy) is evolving to an IP-based packet transport network. A key technology is how to solve the problem of IP packet network Clock and time synchronization issues in . IEEE 1588v2 Ethernet time interface and 1Per PulseSecond+Time Of Day (1PPS+TOD for short) time interface have gradually become the mainstream time synchronization standards in the industry, and have been fully valued by major operators. ITU-T also Researching multiple technical standards of IEEE 1588v2 Ethernet time interface and 1PPS+ToD time interface applied in the field of telecommunication. [0003] In the high-precision time synchronization solution of the communication system, there are various time docking a...
