Network operation, administration, and maintenance (OAM) method, apparatus, and system

摘要

This application discloses a network operation, administration, and maintenance (OAM) method, an apparatus, and a system. The method includes: receiving a fault alarm message sent by an MP, where the fault alarm message includes fault information; determining according to the fault alarm message, a first maintenance set to which the MP belongs, where the first maintenance set includes MPs using a first OAM technology; querying an OAM database, to obtain a second maintenance set interacting with the first maintenance set, where the second maintenance set includes MPs using a second OAM technology; and sending a fault notification message to all MPs in the second maintenance set or an MP that is determined according to a policy in the second maintenance set. Therefore, a related fault alarm may be centrally notified on a management plane, and is decoupled from a specific OAM technology, thereby greatly reducing an implementation difficulty.
