Abstract
A method, system and computer program product for reducing network delay in video conferencing using random tree pushing. A plurality of nodes is randomly selected as next hop forwarders for a piece of content by a source who generates a video stream. Additional next hop forwarders are added to the randomly selected plurality of nodes to form a set of next hop forwarders until a total upload bandwidth of all next hop forwarders is no less than a bandwidth required to deliver the video stream to a set of receivers. The set of receivers in a video session is partitioned and each of the set of receivers is assigned to one of the set of next hop forwarders for forwarding the video stream to an assigned receiver either directly or through a multi-hop path.
