Overview
IEEE 802.1ag calls Ethernet OAM function as connectivity fault
management, which is service-based end-to-end Ethernet OAM function.
The operator-level Ethernet needs to provide different management and
maintenance ranges and contents. Usually, there are three kinds of
organizations refers to operator-level Ethernet services, including user,
service providers and network operators. The users purchase Ethernet
services from service providers. The service providers use their own
network or other operators’ network to provide end-to-end Ethernet
services.
IEEE 802.1ag divides operator-level Ethernet to a multi-domain OAM
network model, including user, service provider and operator maintenance
levels, which correspond with different management domains. The service
provider is responsible for end-to-end service management. The operators
provide service transmission.
Maintenance domain (MD): The network covered by the connectivity fault
management is called management domain. It is defined by a series of
maintenance points (MP) configured on the port. The maintenance domain
name identifies the MD.
According to the 802.1ag multi-domain OAM network model, MD has
