[0004] However, the dedicated OAM message is not the real service message of the user, so the obtained OAM information is not accurate
In addition, the assignment of the fields of the OAM message header needs to be recognized and supported by every node on the link, which is rigid and inefficient

Abstract

The invention discloses a method and system for acquiring OAM information, and a computer readable storage medium, and relates to the technical field of data communication. The method includes that aservice function (SF) node receives a first service message which includes a network service header (NSH) message header which carries an operation administration and maintenance (OAM) information identifier and a programmable instruction indicating the OAM information to be acquired; the SF node, in accordance with the programmable instruction, adds a part of the OAM information to the first service message to form a second service message; and the OAM information in the second service message is acquired from the SF node according to the OAM information identifier. The method can improve theaccuracy of the acquired OAM information.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a method, system and computer-readable storage medium for acquiring Operation Administration and Maintenance (OAM) information. Background technique [0002] At present, in a service chain (Service Chain), generally a dedicated OAM message is forwarded between different nodes to obtain OAM information, thereby obtaining the network status of the service chain. The dedicated OAM message is only used to obtain OAM information, and has no other function. [0003] For example, if you want to obtain certain OAM information, you can assign a value to a field in the header of the dedicated OAM message to define the type of OAM information, and then forward the dedicated OAM message between different nodes . [0004] However, the dedicated OAM message is not a real service message of the user, so the obtained OAM information is not accurate. In addition, the assignm...
