Abstract
Highlights two approaches for controlling traffic on shared communication links. The first was developed by Bolt Beranek and Newman Inc. (BBN) and is known as Fair-Share. The second was conceived at the Lawrence Berkeley Laboratory (LBL) and is known as Class Based Queuing (CBQ). Both mechanisms attempt to provide guaranteed bandwidth utilization to traffic flows with explicit bandwidth requirements while allowing any unused bandwidth to be shared among competing traffic flows. As part of the investigation, tests were conducted using an implementation of the BBN Fair-Share. This report describes the test scenarios, presents the test results, and tenders the resulting observations and conclusions. This report also provides an overview of other components in addition to traffic control algorithms which should be present to support real-time applications. They include Classifiers, Admission Control Procedures and Reservation Setup Protocols.
