Description
Configure a Y.1564 bandwidth profile. A bandwidth profile defines traffic parameters for a service instance and applies at the ingress and egress user‑to‑network interface (UNI). The bandwidth profile defines an upper bound on the volume of the expected number of service frames belonging to a particular service instance.
Using the bandwidth profile, the software processes ingress service frames based on their conformance to these traffic parameters:
-
committed information rate (CIR)
-
excess information rate (EIR)
The software assigns a higher discard precedence to frames that conform to the EIR (known as yellow colored frames) than that assigned to frames that conform to CIR (known as green colored frames). You should expect yellow frames to be dropped first when congestion is encountered at the service layer. Frames that do not conform to either CIR or EIR (known as red colored frames) are dropped at the interface.
Default
Disabled
Options
| cir rate |
Configure a rate for the committed information rate (CIR) parameter. The CIR is the maximum sustained information rate (IR) the network is committed to transfer while meeting the performance level guaranteed in the SLA.
|
| cir-steps number |
Configure the number of steps for the CIR test.
|
| eir rate |
Configure a rate for the excess information rate (EIR) parameter. The EIR is the maximum sustained IR by which a user can exceed the CIR, with some expectation that the excess traffic might be carried though the network.
|
| step-duration seconds |
Configure the duration of a step for the CIR test. If the
generation information rate (IR) is ≤ 1 Mbps, we recommend
setting
|
| traffic_policing |
Specify that nonconforming frames (known as red colored frames) are dropped at the interface. We assume that the service has a configured QoS profile, with CIR, EIR, and maximum frame loss ratio, delay, and jitter values for conforming frames. If a test is color blind, the test has only one flow and one QoS class. The initiator generates frames at a rate of CIR + (1.25 x EIR). (However, if the EIR is less than 20% of CIR, the frames are generated instead at a rate of (1.25 x CIR) + EIR.) The terminator measures received rate, loss, delay, and jitter on the flow. This test fails if the measured rate is higher than CIR + (1.05 x EIR) or less than CIR x (1 - maximum frame loss). |
