10.3.6 Frame Loss Measurement

Two local counters for each peer MEP:

TxFCf: Counter for in-profile data frames transmitted towards peer MEP

RxFCf: Counter for in-profile data frames received from peer MEP

Single-ended ETH-LM:

On demand OAM

MEP sends LMM frame (Unicast DA or Multicast Class 1 DA) and receives LMR frame (Unicast DA) with counters

CCM frames contain frame counters.

Single Ended Frame Delay Measurement

LMM frames contain frame counters.

10.3.7 Delay Measurement

On demand OAM for measuring Frame Delay (FD) and Frame Delay Variation (FDV):

TxTimeStampf = Timestamp transmission of DMM frame

RxTimef = Reception time of the DMM frame

RxTimeb = Reception of DMR frame

Two-way ETH-DM:

DMM frame (Unicast DA or Multicast Class 1 DA for multipoint measurement) & DMR frame (Unicast DA)

FD = RxTimeb – TxTimeStampf

Dual Ended Frame Delay Measurement

DMM and DMR frames contain timestamp info.
