We study the necessity of predictive information in a class of queueing admission control problems, where a system manager is allowed to divert incoming jobs up to a fixed rate, in order to minimize the queueing delay experienced by the admitted jobs. Spencer et al. (2014) show that the system’s delay performance can be significantly improved by having access to future information in the form o...

Over the last few years, a substantial number of call admission control (CAC) schemes have been proposed for ATM networks. In this paper, we review the salient features of some of these algorithms. Also, we quantitatively compare the performance of three of these schemes.

Allocating resources for multimedia traffic flows with real-time performance requirements is an important challenge for future packet networks. However, in large-scale networks, individually managing each traffic flow on each of its traversed routers has fundamental scalability limitations, in both the control plane’s requirements for signaling, state management, and admission control, and the ...

| We address the issue of call acceptance and routing in ATM networks. Our goal is to design an algorithm that guarantees bounds on the fraction of cells lost by a call. The method we propose for call acceptance and routing does not require models describing the traac. Each switch estimates the additional fraction of cells that would be lost if new calls were routed through the switch. The rout...

We propose a network-based endpoint admission control system for scalable QoS guaranteed real-time communication services. This system is based on a sink tree-based resource management strategy, and is particularly well suited for differentiated-services based architectures. By performing the admission decision at the endpoints, the flow setup latency and the signaling overhead are kept to a mi...

Abstrncr . Admission eontml is a critical element for supporting Quality-of-Service in networks. We pmpase and evaluate the performance of an adaptive inadmission contml scheme that is suitable for use in a Differentiated Services Internet backbone. The pmposed scheme impmves upon the admission cuotml scheme by measur. ing the maximal arrival rate envelope at an ingress node and adding an adapt...

We propose and evaluate admission control mechanisms for ACCORD, an Admission Control and Capacity Overload management Real-time Database framework|an architecture and a transaction model|for hard deadline RTDB systems. The system architecture consists of admission control and scheduling components which provide early noti cation of failure to submitted transactions that are deemed not valuable...

Web servers must be protected from overload since server overload leads to low server throughput and increased response times experienced by the clients. Server overload occurs when one or more server resources are overutilized. In this paper we present an adaptive architecture that performs admission control based on the expected resource consumption of requests. By dynamically setting the max...

In this paper, the capacity analysis for connection admission control is presented for the reverse-link transmission of a packetized indoor multimedia wireless communication system using direct sequence code division multiple access (DS/CDMA). Since CDMA is interference limited, the signal-to-interference-plus-noise ratio criterion is used to check if there is enough system resources (i.e., the...
