US 6,192,406 B1 · Startup management system and method for networks

Abstract

A startup management system and method, particularly adapted for use in computer and other communication networks, is presented. Rate-based flow and congestion control mechanisms have been considered desirable, including to deal with the needs of emerging multimedia applications. Explicit rate control mechanisms achieve low loss because of a smooth flow of data from sources, while adjusting source rates through feedback. However, large feedback delays, presence of higher priority traffic and varying network conditions make it difficult to ensure feasibility (i.e., the aggregate arrival rate is below the bottleneck resource's capacity) while also maintaining very high resource utilization. The invention applies entry and early warning techniques which increase the initial connect rate of newly connecting sources.

Dependent claims

A startup management system for managing the startup of a source making a resource request through a communication link to a network, comprising:

a network monitoring unit, for monitoring the available resources of the communication link;
and
a source rate adjustment unit, for adjusting the rate at which the source would begin to transmit over the communication link before the source queues data for transmission according to an allocative function of the available resources of the link which is determined based on a connection setup message, wherein source rate adjustment unit adjusts the rate allocated to the source by applying a max-min fairness criteria to the source, as the allocative function, and wherein the max-min fairness criteria is applied when a connection setup message arrives from the source.

Dependencies are inferred from the claim text.
