OAM Service Multi-Domain Levels

A Service Instant creates a Maintenance Association (MA, or MEG: Maintenance Entity Group)
between various end paths which consist of "Maintenance End Points" (MEPs) located at the edge
of each domain and Ethernet hops or ports referred to as Maintenance Intermediate points (MIP).
There are eight levels defined and classified:
Classification
Customer Domain level
Service Provider domain
Operator Domain level
These levels provide a hierarchy for the service OAM operation, and helps in the fault isolation and
the domain allocation at which a faulty event has occurred.
The highest level 7 always represents the whole connection path from the customers' point of
view, whereas the lowest level, level 0, represents mainly the Ethernet section (the physical links).
The figure below illustrates the multi-domain levels concept.
