摘要

We present adaptive network Quality of Service (QoS) technology that provides delay bounds and capacity guarantees for traffic belonging to mission-critical tasks. Our technology uses a Bandwidth Broker to provide admission control and leverages the differentiated aggregated traffic treatment provided by today's high-end COTS layer-3/2 switches. The technology adapts to changes in network resources, work load and mission requirements, using two components that are a particular focus of this paper: Fault Monitor and Performance Monitor. Our technology is being developed and applied in a CORBA-based multi-layer resource management framework.
