Abstract
Operations, Administration, and Maintenance (OAM) scaling systems and methods are implemented by a network function performed by one of a physical network element and a virtual network element executed on one or more processors. The OAM scaling method includes providing N packet services, N is an integer; and, responsive to determined OAM session scaling limits, providing OAM sessions for the N packet services in an oversubscribed manner, wherein the determined OAM session scaling limits include M OAM sessions supported by the network function, M is an integer and less than N.

An Operations, Administration, and Maintenance (OAM) scaling method performed by one of a physical network element and a virtual network element executed on one or more processors, the OAM scaling method comprising:
- providing N packet services, N is an integer;
- automatically determining OAM session scaling limits by a network function based on one or more of a value of N, a measurement cycle, and a session scale for each of M OAM sessions;
- and
- responsive to the determining of the OAM session scaling limits, providing the M OAM sessions for the N packet services in an oversubscribed manner, wherein the OAM session scaling limits determine a value of M supported by the network function, M is an integer and less than N.
A network device configured to perform Operations, Administration, and Maintenance (OAM) scaling, the network device comprises:
- a switching fabric configured to switch packets;
- and
- a control plane communicatively coupled to the switching fabric, wherein the control plane comprises one or more processors configured to
- manage N packet services, N is an integer;
- automatically determine OAM session scaling limits by a network function based on one or more of a value of N, a measurement cycle, and a session scale for each of M OAM sessions;
- and
- responsive to the determining of the OAM session scaling limits, manage the M OAM sessions for the N packet services in an oversubscribed manner, wherein the OAM session scaling limits determine a value of M supported by the network function, M is an integer and less than N.

- create service sets based on the determined OAM session scaling limits;
- and
- assign each of the M OAM sessions to one of the service sets, wherein the M OAM sessions are managed based on the service sets.
