Pseudowire OAM: A Mandatory Yet Often Overlooked Feature

Until recently, the area of operations and management has not been of concern to those developing and deploying pseudo-wires in leu of the focus on deploying the basic technology. However, of late, operators are now quickly realizing that the success of pseudo-wire deployments largely depends on OAM functions both to determine the functional state of the emulated services, but also to verify SLAs. These operators are now demanding that critical operations and management functions such as connection verification, path trace and SLA measurements be bundled with pseudo-wire equipment. In fact, many are even refusing to deploy pseudo-wire services commercially until OAM functions are included in the devices they use. This presentation discusses customer requirements for OAM that have been presented to the ITU and IETF that outline the need for OAM functions in pseudo-wire deployments, as well as some solutions that have been proposed to these requirements both by the IETF and ITU standards bodies.
