Diffusion approximation modeling for Markov modulated bursty traffic and its applications to bandwidth allocation in ATM networks

Qiang Ren, H. Kobayashi
1998 IEEE Journal on Selected Areas in Communications  
This formulation allows a more general source model than the well studied "on-off" source model in characterizing variable bit rate (VBR) sources such as compressed video.  ...  The queueing behavior of buffer content is analyzed by applying a diffusion process approximation to the aggregate arrival process.  ...  Anick, Mitra, and Sondhi [2] present a comprehensive analysis of a fluid-flow model with single type "on-off" sources. Kosten [19] extends [2] to multiple types of traffic.  ...

An Efficient Bandwidth Assignment Algorithm for Real-Time Traffic in ATM Networks [chapter]

Alamin A. Belhaj, László Pap
2000 IFIP Advances in Information and Communication Technology  
The loss probability is estimated from the asymptote of the tail probability by introducing a correction factor.  ...  In this paper we propose an algorithm for call admission control based on a simple and accurate estimate of the cell loss probability considering both cell scale and burst scale components.  ...  To describe the On-Off sources we assume the source switches from On state to Off state with probability 1 -P11 and switch from Off state to On state with probability 1-Poo.  ...

A testbed for network performance evaluation and its application to connection admission control algorithms

Magnos Martinello, Edmundo de Souza e Silva
2001 Journal of the Brazilian Computer Society  
The environment tools include a traffic generator supporting IP and native-ATM as well as a CAC module that implements the algorithms above and can be used in conjunction with our test environment.  ...  We demonstrate how a study of the effectiveness of different CAC algorithms can be performed from measurements collected using an ATM switch and the tools we developed.  ...  Consider a model with N independent on-off traffic sources regulated by leaky bucket.  ...

In packet-switched network traffic management and control, efficiently allocating bandwidth to provide quantitative packet-level QoS to aggregate traffic has been difficult due to unpredictable, unknown  ...  With inaccurate traffic information, using static bandwidth allocation results in the network being underutilized, or the QoS requirement not being satisfied.  ...  ACKNOWLEDGMENTS This research was supported in part by the NSF CAREER award ANI-9702389.  ...

An adaptive scheme for admission control in ATM networks

Saragur M. Srinidhi, William H. Thesling, Vijaya K. Konangi
1997 Computer networks and ISDN systems  
They estimated the cell loss probability through the use of a queuing model with an input process determined from the traffic flow description.  ...  The two state fluid-flow model adopted here is based on the rationale that a source is either in an "idle state" transmitting at zero bit rate, or in a "burst state" and transmitting at its peak rate [  ...

2014 IEEE Transactions on Vehicular Technology  
Moreover, when compared to the computation time required in a standard discrete event simulator, the fluid flow based model is shown to be a more scalable tool.  ...  Our approach is a hybrid of a time varying adjacency matrix and a fluid flow queuing network model.  ...  All links switch between on/off randomly following the two-state Markov process.  ...

Explicit rate flow control for ABR services in ATM networks

Ching-Fong Su, G. De Veciana, J. Walrand
2000 IEEE/ACM Transactions on Networking  
The goal is to guarantee low cell loss in order to avoid throughput collapse due to retransmission by higher level protocols.  ...  We propose a novel explicit rate flow control algorithm intended for Available Bit Rate (ABR) service on an ATM network subject to loss and fairness constraints.  ...  We used the NIST ATM network simulator for the simulation in this paper.

Admission of QoS aware users in a smart network

Erol Gelenbe, Georgia Sakellari, Maurizio D'arienzo
2008 ACM Transactions on Autonomous and Adaptive Systems  
The algorithm uses a novel algebra of QoS metrics, inspired by Warshall's algorithm, to look for a path with acceptable QoS values to accommodate the new flow.  ...  When a new user requests to enter the network, probe packets are sent from the source to the destination to estimate the impact that the new connection will have on the QoS of both the new and the existing  ...  It assumes that traffic follows an on-off behavior and exploits information about buffer sizes and the multiplexed traffic that shares a common link, to obtain a diffusion approximation based on an estimate  ...

Fairness and Optimal Stochastic Control for Heterogeneous Networks

M.J. Neely, E. Modiano, Chih-Ping Li
2008 IEEE/ACM Transactions on Networking  
A dynamic strategy is developed to support all traffic whenever possible, and to make optimally fair decisions about which data to serve when inputs exceed network capacity.  ...  The cost of approaching this fair operating point is an end-to-end delay increase for data that is served by the network.  ...  A wireless downlink with deterministic ON/OFF channels and arbitrary input rates is developed in [30] , and a modified version of the Serve-the-Longest-ON-Queue policy is shown to yield maximum throughput  ...
