Method for processing light direction information of communication channels of packet transport equipment

Abstract

The invention discloses a method for processing light direction information of communication channels of packet transport equipment and relates to the field of packet transport network equipment. The method comprises the following steps of: identifying the light direction information in a management communication channel (MCC) and a signaling communication channel (SCC) of the packet transport network equipment, wherein the light direction information comprises slot position information and light port information; placing the slot position information at the high order of the light direction information, and placing the light port information at the low order of the light direction information; and identifying and processing the high order of the light direction information, carried by a management frame received by a management card, by the management card, and identifying and processing the low order of the light direction information, carried by the management card received by a business card, by the business card. In the invention, the business card processes the light port information in the light direction information, and the management card processes the slot position information; therefore, the work load of the business card is reduced, the working efficiency is improved, and simple and efficient management is realized; and moreover, when a slot position is increased in a system or a new system is developed, compatibility can be realized by only updating the management card, without changing the business card.

Description

technical field [0001] The invention relates to the field of packet transmission network equipment, in particular to a method for processing light direction information of a communication channel of a packet transmission equipment. Background technique [0002] Packet Transport Network (PTN, Packet Transport Network) refers to such an optical transport network architecture and specific technology: a layer is set between IP services and the underlying optical Designed to meet the requirements of transmission, it takes packet services as the core and supports multi-service provisioning, has a lower total cost of use (TCO, Total Cost of Ownership), and at the same time inherits the traditional advantages of optical transmission, including high availability and reliability, high efficiency Advanced bandwidth management mechanism and traffic engineering, convenient OAM and network management, scalability, high security, etc. According to the actual needs of the operator's networ...

Problems solved by technology

The internal management channel of the packet transmission equipment includes the management communication channel MCC and the signaling communication channel SCC. The OAM protocol standard preliminarily stipulates the format of the two OAM frames, MCC and SCC, but it does not specify how MCC and SCC are used in the packet transmission network equipment.
