Sublinks Example
Assume the following sublink packet endpoint is connected to the frame re-
lay network via a full T1:
If the PVC to San Francisco needs to transmit data, it will be able to access
the network at full T1 rates. If, at the same time, data needs to be transmitted
to the PVC to New York, the San Francisco and New York PVCs would
equally share the T1 to the frame relay provider because they have the same
QOS value. If, also at the same time, data needed to be transmitted to the
PVC to Atlanta, the T1 would be divided three ways: traffic to Atlanta gets
half of the T1, and the New York and San Francisco PVCs equally share the
remaining half of the T1, since they share the same QOS value.
