Technique for end-to-end admission control of real-time packet flows

摘要

A technique for end-to-end admission control of real-time packet flows is disclosed. In one 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 include transmitting at least one probe packet from a first network element to a second network element via a network path, determining, at 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.

主权项

1. A network node for a packet-based communication network, the network node comprising:
at least one communication interface for coupling the network node to the communication network; a traffic conditioner coupled to the at least one communication interface, the traffic conditioner being configured to:
receive at least one probe packet on a network path which includes the network node;determine at least one flow rate associated with a plurality of packets;compare the at least one flow rate to at least one predetermined threshold;set an explicit congestion notification (ECN) in the at least one probe packet based on the comparison of the at least one flow rate to the at least one predetermined threshold; andforward the at least one probe packet on the network path.
