Excess Burst Size
|
EBS is a Bandwidth Profile parameter. It limits the maximum number of bytes available for a burst of ingress Service Frames sent at the UNI speed to remain EIR-conformant
|
|
Excess Information Rate
|
EIR is a Bandwidth Profile parameter. It defines the average rate in bits/s of ingress Service Frames up to which the network may deliver Service Frames without any performance objectives. The rate up to which the network will attempt to deliver Ethernet service frames before they are discarded.

Frame Delay Performance
|
A measure of the delays experienced by Service Frames belonging to the same CoS instance
|
|
Frame Delay Variation
|
The difference in delay of two Service Frames
|
|
Frame Delay Variation Performance
|
A measure of the variation in the delays experienced by different Service Frames belonging to the same CoS instance.
|
|
Frame Loss Ratio Performance
|
Frame Loss Ratio is a measure of the number of lost frames between the ingress UNI and the egress UNI. Frame Loss Ratio is expressed as a percentage.
