Delay Measurement Parameters
Delay Measurement
Enable
Delay Measurement based on transmitting 1DM/DMM PDU can be
enabled/disabled. Delay Measurement based on receiving and handling
1DM/DMR PDU is always enabled.
Priority
The priority to be inserted as PCP bits in TAG (if any).
Cast
Selection of 1DM/DMM PDU transmitted unicast or multicast. The unicast
MAC will be configured through 'Peer MEP'.
Peer MEP
This is only used if the 'Cast' is configured to Uni. The 1DM/DMR unicast
MAC will be taken from the 'Unicast Peer MAC' configuration of this peer.
Way
One-Way:
One-Way Delay Measurement implemented on 1DM.
Two-Way:
Two-Way Delay Measurement implemented on DMM/DMR.
Tx Mode
Standardize:
Y.1731 standardize way to transmit 1DM/DMR
Proprietary:
proprietary way with follow-up packets to transmit 1DM/DMR
Calc
This is only used if the 'Way' is configured to Two-way.
Round trip:
The frame delay calculated by the transmitting and receiving
timestamps of initiators. Frame Delay = RxTimeb-TxTimeStampf
Flow:
The frame delay calculated by the transmitting and receiving
timestamps of initiators and remotes. Frame Delay = (RxTimeb-
TxTimeStampf)-(TxTimeStampb-RxTimeStampf)
Gap
The gap between transmitting 1DM/DMM PDU in 10ms. The range is 10 to
65535.
Count
The number of last records to calculate. The range is 10 to 2000.
Unit
The time resolution
D2forD1
Enable to use DMM/DMR packet to calculate one-way DM. If the option is
enabled, the following action will be taken. When DMR is received, two-way
delay (roundtrip or flow) and both near-end-to-far-end and far-end-to-near-
end one-way delay are calculated. When DMM or 1DM is received, only far-
end-to-near-end one-way delay is calculated.
