in-service OAM
"In-service OAM refers to OAM actions which are carried out while
the data traffic is not interrupted with an expectation that data traffic
remains transparent to OAM actions."
on-demand OAM
"On-demand OAM refers to OAM actions which are initiated via manual
intervention for a limited time to carry out diagnostics.
On-demand OAM can result in singular or periodic OAM actions during
the diagnostics time interval."
out-of-service OAM
"Out-of-service OAM refers to OAM actions which are carried out while
the data traffic is interrupted."
proactive OAM
"Proactive OAM refers to OAM actions which are carried out continuously
to permit proactive reporting of fault and/or performance results."
