Experimental Study of Bandwidth Assurance in a DiffServ Network
نویسندگان
چکیده
Inside DiffServ, the Assured Forwarding per hop behavior defines a service that guarantees the contracted target rate to the users and allows consuming more bandwidth if the network load is low. In this paper we perform an experimental study, whose key contribution is that current techniques and commercial equipment do not meet the goals of the AF PHB service in a scalable way.

On improving bandwidth assurance in AF-based DiffServ networks using a control theoretic approach
The Assured Forwarding (AF) based service in a Differentiated Services (DiffServ) network fails to provide bandwidth assurance among competing aggregates under certain conditions, for example, where there exists a large disparity in the round-trip times, packet sizes, or target rates of the aggregates, or there exist non-adaptive aggregates. Several mechanisms have been proposed in order to add...
متن کاملBandwidth Assurance Issues for TCP flows in a Differentiated Services Network *
Much industry attention has recently been focused on providing differentiated levels of service to users on IP networks. One such proposal is the RIO scheme proposed by Clark [4]. RIO is an extension of the RED algorithm that relies on a differentiated drop treatment during congestion to cause different levels of service. The end result of differentiated dropping of packets during congestion is...
متن کاملIntelligent Traffic Conditioners for Assured Forwarding Based Differentiated Services Networks
Issues related to bandwidth assurance in Assured Forwarding based Differentiated Services (Diffserv) networks have been discussed in recent research papers [7][8][11]. Some of the factors that can bias bandwidth assurance are Round Trip Time (RTT), UDP/TCP interaction and different target rates. The bias due to these factors needs to be mitigated before bandwidth assurance for a paying customer...
متن کاملUsing TCP models to understand bandwidth assurance in a Differentiated Services network
this paper, a comprehensive analytical model to predict the bandwidth achieved by aggregates of TCP flows in a Diffserv network is presented. The model predicts achieved bandwidth in three different cases: an over-provisioned network, an under-provisioned network, and a near-provisioned network. In developing the model, we ensure that all parameters are measurable using standard tools and infor...
متن کاملDiffserv’s Assured Forwarding PHB: What Assurance does the Customer Have?
This paper examines issues related to assuring the throughput performance parameters of a Service Level Agreement in an Assured Forwarding based Diffserv-capable IP network. In an effort to understand the kinds of quantifiable parameters that can be included in a contract, the analysis of detailed studies on throughput are presented. Seven different factors are discussed which can bias bandwidt...
