Problems solved by technology

[0016] From the above description of the CC implementation method, it can be seen that before the CC function is started, if the network has a fault such as fiber breakage or configuration error, the current CC mechanism will not be able to detect the fault.
as attached figure 1 , attached figure 2 , attached image 3 In , it is assumed tha...

Embodiment Construction

[0053] The core of the present invention is: setting the maintenance end point that receives the CC message needs to return CCRM (CC response message), and the maintenance point that processes the CC message determines the network status according to the CC response message.

[0054] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0055] In the present invention, the MP that processes the CC message can be the MEP that sends the CC message, or the MIP that receives the CC message and continues to send the CC message, or it can also be: the MEP that sends the CC message and the MIP that receives the CC message to the CC message and send the MIP of the CC message.

[0056] The CC implementation method of the present invention will be described below by using the processing procedures of the MEP sending the CC message, the processing procedure of the MEP receiving the CC message, and the...

Abstract

A method to achieve the continuity check (CC), it is: sets the answer information that the maintenance end receiving the CC information needs to return CC, the maintenance end that processes the CC information bases on the network condition of the CC answer information. The invention can check out the connection fault in the network before or after that the maintenance end startup CC function; improve the veracity of the fault check, perfect the continuity check.

Description

technical field [0001] The invention relates to the technical fields of operation, management and maintenance, and in particular to a method for realizing continuity detection. Background technique [0002] At present, two groups, ITU-T (International Telecommunication Union Telecommunication Standardization Sector) and IEEE (Institute of Electrical and Electronics Engineers), are simultaneously conducting research on the end-to-end OAM (operation, management and maintenance) function of Ethernet, among which ITU-T is in Y.1730 The end-to-end OAM function of Ethernet is described in the two documents of Y.71ehtoam and end-to-end OAM function of Ethernet in the 802.1ag document of IEEE. In the above documents, the ideas of the two organizations are generally the same, and the solutions for OAM functions are also very similar. Among them, the ITU-T documents include alarm and performance parts, which make the OAM system more complete. [0003] At present, the industry has rea...
