Revenue Optimized IPTV Admission Control Using Empirical Effective Bandwidth Estimation

A. Davy, D. Botvich, B. Jennings
2008 IEEE transactions on broadcasting  
Central to the approach is an empirical method of estimating the effective bandwidth required to satisfy QoS targets for admitted traffic flows.  ...  The paper describes this method and specifies two admission control algorithms based on the use of effective bandwidth estimates.  ...  These hybrid techniques use both measurements taken from the network and knowledge of submitted traffic descriptors to predict effective bandwidth requirements of flows.  ...

An approach to measurement based Quality of Service control for communications networks

Alan Davy, Dmitri Botvich, Brendan Jennings
2009 2009 IFIP/IEEE International Symposium on Integrated Network Management  
This paper presents a purely empirical approach to estimating the effective bandwidth of aggregated traffic flows independent of traffic model assumptions.  ...  The approach is shown to be robust when used in a variety of traffic scenarios such as both elastic and streaming traffic flows of varying degrees of aggregation.  ...  QoSPlan uses an estimated effective bandwidth coefficient to relate the estimated traffic demands within the demand matrix to corresponding effective bandwidth requirements of traffic.  ...

Dynamic Bandwidth Management in Single-Hop Ad Hoc Wireless Networks

Samarth H. Shah, Kai Chen, Klara Nahrstedt
2005 Journal on spesial topics in mobile networks and applications  
The center piece of our scheme is a Bandwidth Manager, which allots each flow a share of the channel, depending on the flow's requirements relative to the requirements of other flows in the network.  ...  We present a mapping scheme to translate the bandwidth requirements of an application into its channel time requirements.  ...  The RA of a flow f uses it in the translation of flow f 's bandwidth requirements to its CTP requirements.  ...

A new scheme for traffic estimation and resource allocation for bandwidth brokers

T. Anjali, C. Scoglio, G. Uhl
2003 Computer Networks  
In this paper, a new scheme for estimating the traffic on an inter-domain link and forecasting its capacity requirement, based on a measurement of the current usage, is proposed.  ...  A bandwidth broker acts as the resource manager for each network provider. Neighboring bandwidth brokers communicate with each other to establish inter-domain resource reservation agreements.  ...  In the first step, a rough measure of the aggregate traffic yðmÞ is taken and it is used to evaluate the number of flows through the Kalman filter estimation process.  ...

Towards Bandwidth Estimation Using Flow-Level Measurements [chapter]

Ricardo de O. Schmidt, Anna Sperotto, Ramin Sadre, Aiko Pras
2012 Lecture Notes in Computer Science  
In this paper, we investigate what is the impact of flow-based measurements on bandwidth estimation.  ...  However, flows pose a challenge for bandwidth estimation, namely the coarser data granularity compared to packet-based approaches, which can lead to a lower precision in the estimation of the needed bandwidth  ...  This problem has led us to the following research question: Is it possible to use flow-level measurements instead of packet-level measurements to obtain traffic statistics?  ...

Implicit admission control

R. Mortier, I. Pratt, C. Clark, S. Crosby
2000 IEEE Journal on Selected Areas in Communications  
Internet protocols currently use packet-level mechanisms to detect and react to congestion.  ...  We argue that, in order to achieve better utility of the network as a whole, higher level congestion controls are required.  ...  They are usually much more inelastic in their resource requirements than protocols such as TCP -they have a narrower bandwidth operating region, requiring a minimal level of service to perform useful work  ...

Bandwidth Allocation and Session Scheduling using SIP

Hassan Hassan, Jean-Marie Garcia, Olivier Brun
2006 Journal of Communications  
The suggested mechanisms deal with two issues: first, session scheduling based on session duration and/or volume, and second bandwidth allocation on a per-flow basis using equivalent bandwidth estimation  ...  Hence, we use SIP to achieve QoS management on a session basis, in which the over all activity of the user during the session is considered.  ...  The second mechanism uses the equivalent bandwidth estimation methods to allocate bandwidth per flow.  ...
