ATM networks provide end-to-end QoS guarantees to connections for theirlifetime in the form of bounds on delay, error and/or loss. Theguarantees are important for real-time connections in which losses areirrecoverable and delays cause interruptions in service. Performancemanagement involves measurement of QoS parameters and applying controlmeasures, if required, to improve performance or resource utilization. Inthis paper, we propose a new hierarchical scheduling algorithm based ondynamic priorities which are adaptive to end-to-end QoS measurements madeon QoS sensitive (real-time) connections. This architecture can providebounds on average delay and delay variation with varying backgroundnetwork traffic. <P><P><I>This paper has been submitted to INFOCOM 2000, Tel Aviv Israel, March 26-30, 2000.</I>
