Abstract
This thesis develops a protocol extension, the Preference-based Allocation eXtension for Layered Sources (PAXLS), to complement the existing Scalable ConsensUs based Bandwidth Allocation (SCUBA) protocol used in allocation of bandwidth for layered multicast video conferences. SCUBA operates by allocating bandwidth on a particular channel in a multicast conference based on the interest of the users in each transmitting source. PAXLS extends this model to consider the preferences of the users for receiving video data from each source in a conference. For example, some users may prefer to view a video stream from one source in color at a high frame rate while viewing video streams from other sources in black and white at low frame rates.
