Traffic Policing Examples

Figure 7-16 shows a VBR connection policing example, with the policing set to 4, and leaky

bucket 1 non-compliant which indicates that the connection has exceeded the PCR for a long enough

interval to exceed the CDVT (0+1) limit. Non-compliant cells with respect to leaky bucket 1 are

discarded.
