Abstract—A Particle Swarm optimized Fuzzy Logic Congestion Detection (FLCD) was recently proposed for best-effort service networks. This algorithm synergically combines the good characteristics of traditional Active Queue Management (AQM) algorithms and fuzzy logic based AQM algorithms. Its membership functions are designed automatically by using a Multi-objective Particle Swarm Optimization (M...

Differentiated Services (Diffserv) which was proposed by Internet Engineering Task Force (IETF), is a scalable and robust model for providing the end-to-end QoS. In the Diffserv networks, metering mechanisms are used to measure traffic stream. The single rate Three Color Meter (srTCM) [1],which was proposed by IETF,‏ meters an IP packet stream and marks its packets either green, yellow, or red....

Management of Quality of Service (QoS) performance and resources at runtime is much researched area. In particular, when there are different classes requiring different levels of QoS guarantees raise many research challenges. The relative/proportional guarantee scheme while dynamic resource management is proposed to implement such differentiated services in software systems. The existing approa...

This paper shows how time dependent priorities can be applied to providing service assurance in a call center. The main contribution of this paper is the transfer of several results derived in the field on Proportional Differentiated Services (Internet Quality of Service) to application in the research field of Call Center technology. Further, it addresses some specific aspects of application t...

The proportional Service model is receiving a lot of attention as an attractive model for providing differentiated services on the Internet. In particular, this model is controllable, able to provide the “tuning knobs” for network operators to quantitatively differentiate the quality-ofservice (QoS) of different classes, and lends itself naturally to simple pricing schemes. In this paper, we fo...

In this paper is addressed the issue how to provide QoS control and improve performance in high speed Optical Burst Switching (OBS) networks. In order to provide better proportional differentiated services is proposed a novel burst assembly algorithm (named adaptive timer-based) with traffic shaping functions to reduce the variance of assembled traffic and improve the burst loss performance. Ne...

This paper describes two traffic engineering techniques for implementing proportional differentiated services based on Multiprotocol Label Switching constraint based routing. Both use a dynamic bandwidth allocation scheme to modify the bandwidth reserved by each traffic class according to the current network load. The first scheme uses an adaptive algorithm that qualitatively determines the req...

A key consideration in building differentiated network services is the feasibility of maintaining stable and consistent service level agreements across multiple networks where allocations are made only on the edges. To investigate this, we consider a game theoretic model of capacity provisioning in a differentiated services internet. The players are one raw-capacity seller per network, one brok...
