A novel concept in available bit rate (ABR) service model as de ned by the ATM Forum is the minimum cell rate (MCR) support for each ABR virtual connection. In this paper, we present a fundamental study of rate allocation policies with MCR guarantee. In particular, we de ne three network bandwidth allocation policies that guarantee MCR requirements. For each policy, we present a centralized alg...

BACKGROUND AND OBJECTIVES Auditory brainstem response (ABR) is a noninvasive measurement of a stimulus-locked, synchronous electrical event. ABR provides information concerning the functional integrity of brainstem nuclei. Age is a key factor in the interpretation of ABR peak latency among different age groups. Progressively with time it follows a "maturation pattern" during which latencies dec...

OBJECTIVES/HYPOTHESIS Analysis of auditory brainstem response (ABR) in very preterm infants can be difficult owing to the poor detectability of the various components of the ABR. We evaluated the ABR morphology and tried to extend the current assessment system. STUDY DESIGN Prospective cohort study. METHODS We included 28 preterm very low birth weight infants admitted to the neonatal intens...

We extend our earlier studies of bu er requirements of TCP over ABR [10, 11, 12] in two directions. First, we study the performance of TCP over ABR in an ATM backbone. On the backbone, the TCP queues are at the edge router and not inside the ATM network. The router requires bu er equal to the sum of the receiver window sizes of the participating TCP connections. Second, we introduce various pat...

This paper presents a novel generic weight-based network bandwidth sharing policy and an available bit rate (ABR) algorithm that achieves this policy. Our policy supports the minimum cell rate (MCR) requirement and peak cell rate (PCR) constraint of each connection and allocates network bandwidth among all connections based on a weight associated with each connection. To achieve this policy for...

Auditory Brainstem Response (ABR) is an auditory evoked potential extracted from ongoing electrical activity in the brain. ABR is especially used for newbornand children hearing screening, auditory threshold estimation, and brainstem lesion detection in response to stimuli such as click sound, tone burst or chirp. In order to support clinical decision making the analysis of ABR signals must exh...

In ATM networks, the Available Bit Rate (ABR) service enables data sources to ee-ciently utilize network resources without adversely aaecting the performance of non-ABR, guaranteed traac such as video. Most research to date on ABR performance has not used realistic assumptions. Unrealistic assumptions such as persistent data sources and no non-ABR traac, as well as poor TCP models may lead to m...

The Available Bit Rate (ABR) service has been developed to support 21st century data applications over Asynchronous Transfer Mode (ATM). The ABR service uses a closed-loop rate-based traac management framework where the network divides left-over bandwidth among contending sources. The ATM Forum traac management group also incorporated open-loop control capabilities to make the ABR service robus...
