Abstract

A improved connection shaping technique is disclosed, whereby at least one high-priority 'preemptive' service flow is initiated at a customer entity in order to limit or restrict the effective usable bandwidth on a particular line or connection. According to at least one embodiment, a preempt data parcel corresponds to a data parcel which includes non-meaningful data. When the preempt cells are received at the ingress port of the communication line, the preempt cells may be identified as non-meaningful data parcels, and may be discarded in accordance with conventional protocols.
