Title:
END-TO-END BANDWIDTH ESTIMATION FOR CONGESTION CONTROL IN PACKET SWITCHING NETWORKS
Document Type and Number:
WIPO Patent Application WO2002033889
Kind Code:
A3
Abstract:
The invention herein described consists of an algorithm, which performs an end-to-end estimation of the bandwidth available in an end-to-end connection established between a server and a client via a packet switching network such as a the Internet Protocol Network (IP). This algorithm is used to properly regulate the input rate at the send side. Typical applications are delivering best effort traffic over TCP, or audio and video traffic over RTP/UDP. The invention is particularly effective over wireless Internet and can be used in a content delivery system to dynamically choose the best server between a set of servers to satisfy the request of a client, or to select the best route in a content deliver or global hosting system.
