Abstract

A system and method are provided for providing access communications between customer locations and a core network service edge. Access flows are handled as carrier-tagged flows through a packet switched network comprising network elements that interpret and manipulate carrier tag values associated with traffic-bearing data frames. In accordance with a preferred embodiment, a discard eligibility indication may be provided with the data frames.

Claims

1. In a communication system, a method for providing access communications between a customer premise and a service edge, the method comprising:

receiving a first communication from a customer premise equipment;

encapsulating the first communication by applying an encapsulation structure to a frame of the communication to yield an encapsulated communication, the encapsulation structure comprising a discard eligibility indicator;

determining whether the first communication exceeds a data rate threshold;

responsive to the determining whether the first communication exceeds a data rate threshold, setting a value of the discard eligibility indicator; and

sending the encapsulated communication to the service edge.
