Pre-congestion notification (PCN) marks packets when the PCN traffic rate exceeds an admissible link rate and this marking information is used as feedback from the network to take admission decisions for new flows. This idea is currently under standardization in the IETF. Different marking algorithms are discussed and various admission control (AC) algorithms are proposed that decide based on t...

 FARIMA(p,d,q) model is a good traffic model capable of capturing both the long-range and short-range behavior of a network traffic stream in time. In this paper, we propose a prediction-based admission control algorithm for integrated service packet network. We suggest a method to simplify the FARIMA model fitting procedure and hence to reduce the time of traffic modeling and prediction. Our ...

Admission control and overload management techniques are central to the design and implementation of Real-Time Database Systems. In this paper, we motivate the need for these mechanisms and present protocols for adding such capabilities to Real-Time Databases. In particular , we present a novel admission control paradigm, we describe a number of admission control strategies and contrast (throug...

A joint scheduling and admission control algorithm is presented for Asynchronous Time-Sharing (ATS)-based switching nodes carrying real-time traac. Systems based on ATS guarantee quality of service, at both the levels of cells and calls, for three well-deened traac classes. A mechanism is outlined by which an admission control strategy can be tailored to a particular mix of traac by making use ...

We consider the problem of joint resource allocation and admission control in a secondary code-division network coexisting with a narrowband primary system. Our objective is to find the maximum number of admitted secondary links and then find the optimal transmitting powers and code sequences of those secondary links such that the total energy consumption of the secondary network is minimized s...

Abstract: The core aspect of most multimedia applications is the transmission of Variable Bit Rate (VBR) video streams requiring a sustained relatively high bandwidth with stringent Quality of Service (QoS) guarantee. In such systems, a statistical bandwidth estimation is especially relevant as it is indispensable for implementing an efficient admission control. In this paper a novel measuremen...

Multihop WiMAX networks show a lot of promise as the last mile in broadband connections for streaming audio and video to users. Such WiMAX networks are based on IEEE 802.16, which specifies the service classes for Q u a l i t y o f S e r v i c e ( QoS), but leaves the admission and scheduling mechanisms open. This paper presents a flow admission control and scheduling scheme for multihop WiMAX ...

This paper introduces and studies a new queue management framework via the use of connection level information already embedded in existing data traffic. Our goal is to improve the system performance and resource utilization at times of intense network congestion. Under this framework, data packets and connection establishment packets are queued separately. Different queueing and dropping polic...

Rate monotonic traffic scheduling algorithm had been shown [1] to be the optimal static priority assignment scheme. The system model studied in [1] can be considered (although not realistic) as a preemptive multiplexer which accepts constant bit rate connections that generate packets periodically. The multiplexer adopts a service discipline such that a lower priority packet can be preempted at ...
