Congestion management in telecommunications networks
First Claim
1. A method comprising:
- receiving at a protocol-data-unit excisor a metric of a queue in a first congestible node; and
selectively dropping, at said protocol-data-unit excisor, one or more protocol data units en route to said first congestible node based on said metric of said queue in said first congestible node.

Abstract
A technique for lessening the likelihood of congestion in a congestible node is disclosed. In accordance with the illustrative embodiments of the present invention, one node—a proxy node—drops protocol data units to lessen the likelihood of congestion in the congestible node. In some embodiments of the present invention, the proxy node receives a metric of a queue at a congestible node and, based on the metric, decides whether to drop protocol data units en route to the congestible node. In some other embodiments of the present invention, the proxy node estimates a metric of a queue at a congestible node and, based on the metric, decides whether to drop protocol data units en route to the congestible node.

7. A method comprising:
-
observing at a protocol-data-unit excisor the flow of protocol data units en route to a first congestible node;
estimating a metric of a queue of protocol data units in said first congestible node based on said flow of protocol data units; and
selectively dropping, at said protocol-data-unit excisor, one or more protocol data units en route to said first congestible node based on said metric of said queue of protocol data units in said first congestible node. - View Dependent Claims (8, 9)
