Abstract

The invention discloses a device and a method for transmitting network element protocol messages in optical network equipment, and relates to the field of photo-communication. The device for transmitting the messages comprises seven hardware entity units: an ECC message aggregation and separation unit, an ECC frame and ether OAM frame converting unit, a packet interface adaptive unit, a packet switching unit, an ECC frame and HDLC frame converting unit, an OTN interface adaptive unit and an OTN framing unit, the device for transmitting the messages is positioned on one side of a back plate, and a control and management unit is arranged on the other side of the back plate. By application of the device and the method for transmitting the network element protocol messages in the optical network equipment, ECC messages of packet services and OTN services in the optical network equipment can be transmitted according to a uniform standard, and after the processing of all service units, the ECC information is transmitted to far-end equipment through service ports of different types.

Description

technical field [0001] The invention relates to the field of optical communication, in particular to a device and method for transmitting network element protocol messages in optical network equipment. Background technique [0002] ECC (Embedded Control Channel, Embedded Control Channel) in the optical network is a logical channel for transmitting OAM (Operation Administration and Maintenance, operation, management, maintenance) information. The ECC protocol stack refers to OSI (Open System Interconnect, Open System Interconnect) Based on the model, the application layer of the ECC protocol stack includes CMISE (Common Management Information Service Element, public management information service unit), ROSE (Remote Operation Service Element, remote operation service unit) supporting CMICE, and ACSE (Association Control Service Element, joint control service unit). The presentation, session, and transport layers provide the connection-oriented services required to support RO...
