Abstract

A technique for end-to-end admission control of real-time packet flows is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for end-to-end admission control of real-time packet flows in a network having a plurality of network elements. The method may comprise transmitting at least one probe packet from a first network element to a second network element via a network path, determining, at least one intermediate network element on the network path, at least one flow rate associated with a plurality of packets, marking at least one predetermined bit in the at least one probe packet if the at least one flow rate is greater than a predetermined rate, and controlling an admission of additional packets into the network based at least in part on the marking of the at least one predetermined bit in the at least one probe packet.

Claims (6)

1. A system for end-to-end admission control of real-time packet flows in a network, the system comprising:

a first network element that transmits at least one probe packet to a second network element via a network path;

at least one intermediate network element on the network path that:

determines at least one flow rate associated with a plurality of packets; and

encodes at least two predetermined bits in the at least one probe packet based at least in part upon a level of congestion associated with the at least one flow rate; and

an admission control module that controls an admission of additional packets into the network based at least in part on an examination of the at least two predetermined bits in the at least one probe packet.
