METHOD FOR PROCESSING MESSAGE AND NETWORK ELEMENT APPARATUS

摘要

A method for processing a message and a network element apparatus. The method comprises: assembling a precision time protocol (PTP) message; and inserting the PTP message into a reserved byte of an overhead of an optical transport unit (OTU) frame or mixing the PTP message into an Ethernet message to be transmitted. This solution can implement interaction of the PTP protocol message between network elements of a wavelength division network, so that the PTP protocol message can be transferred and analyzed among the network elements, and thereby precision time transfer of the wavelength division network can be realized.
