Filed:

Apr 1, 2005

Appl. No.:

11/096735

Inventors:

Azer Bestavros - Wayland MA, US
Abraham Matta - Wayland MA, US

International Classification:

H04L012/26

US Classification:

370477000

Abstract:

Method and apparatus for providing enhanced utilization of an existing network of paths between nodes allocated to customer traffic where the paths also carry cross traffic. The system monitors the quality of the network bandwidth utilized by customer data flows over a set of managed paths in a time interval and allocates network resources to customers as a function of measured bandwidth and a desired target thereof by acquiring additional paths or abandoning existing paths. A scheduling function controls the use of the set of managed paths to more nearly achieve the desired quality of network bandwidth delivered to customer traffic.

Abstract:

The invention relates to a transport protocol and associated methods and stack architectures for improving the energy efficiency of transmitting packets through an ad hoc network. The protocol controls transmissions by taking into account per-packet energy limits, per-node loss tolerances, and/or minimum availability rates determined based on path quality measurements collected by packets traversing the network and application reliability requirements associated with various applications.
