Abstract

The invention provides a method for sending and acquiring messages transmitted by timing transparent transcoding (TTT), sending equipment and receiving equipment. The method comprises the following steps of: sending service messages; receiving clock messages; and recording the bytes of the clock messages; inserting the clock messages among the service messages for sending, namely caching the service messages to be sent; sending the clock messages; after the clock messages are sent, acquiring the service messages to be sent from a cache, and deleting code words of which the bytes are the same as those of the inserted clock messages in the service messages; and sending the service messages to be sent of which the code words are deleted. By the method and the equipment in the embodiment of the invention, the clock messages can be extracted, and the service transmission is not influenced.

Description

technical field [0001] The invention relates to a clock message processing technology, in particular to a method for sending and acquiring a message transmitted by TTT and a sending and receiving device. Background technique [0002] The full name of IEEE 1588 is the Precision Clock Synchronization Protocol for Networked Measurement and Control Systems (IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems), referred to as the Precise Time Protocol (PTP). The purpose of PTP is to maintain time synchronization between different nodes in Ethernet. Gigabyte Ethernet (GE) Time Transparent Transcoding (Timing Transparent Transcoding, TTT) transmission mode is a synchronous transmission mode of GE business, which is derived from the general framing procedure of GE transparent mode (Transparent) ( Generic Framing Procedure, GFP-T) evolved. The realization principle is as follows: in the receiving direction, 8B / 10B decoding is p...
