This is a survey paper on Quality-of-Service(QoS) based routing. In this paper, we first introduce the concept of Quality-of-Service and its background. Second, we discuss the concepts of QoS-based routing, its objectives and main issues. After that, several types of QoS based routing algorithms are compared, and the advantages and disadvantages of each type discussed. Then, the relations betwe...

VoIP services are scarifying, due to delay in transmission of voice packets (Latency), echo, jitter, packet loss and other Quality of Service (QoS) problems arrived in VoIP phones. The weakness on QoS is managing by voice and data service together on a VoIP network. In this paper we dedicated to studying the response of data transmission quality, characteristic of voice quality, the service qua...

In this paper, we address the issue of multiservice packet demand modeling in the radio dimensioning process for 3G/IMT-2000 systems. For packet services, Quality of Service (QoS) is measured as a time delay over the radio interface. New tables stemming from simulations are proposed to convert the volume of packet data expressed in Mbits into a required pipe respecting the QoS. The mix of packe...

In this paper, the authors develop a comprehensive framework for QoS management based on soft probabilistic contracts. The authors approach also encompasses general QoS parameters, with “response time” as a particular case. In addition, the authors support composite QoS parameters, for example, combining timing aspects with “quality of data” or security level. They also study contract compositi...

WiMAX (Worldwide Interoperability for Microwave Access) has been developed with advantages such as high transmission rate and predefined quality of service (QoS) framework, enabling efficient and scalable networks for data, video and voice. WiMAX networks were expected to be the main Broadband Wireless Access (BWA) technology that provided several services such as data, voice, and video service...

Autonomous Decentralized System (ADS) has the properties of online expansion, online maintenance and fault tolerance, which are among the important features for next generation information services. Since information services require transfer of large amounts of data with different levels of Quality of Services (QoS), it is necessary to have an ADS architecture to satisfy these requirements. Th...

Cloud is an advancing technology where the the concept of service oriented architecture, distributed, autonomic, and utility computing is being utilized by various service providers. The current changing world is highly challengeable to build high-quality cloud application. Since QoS ranking that provide beneficial information for optimal cloud service selection is time consuming and expensive,...

We propose a Service-oriented Middleware (SoM) that provides an upper level of middleware over rapidly emerging Web Services-based middleware to make it easier to develop complex multi-organizational business applications. Our approach primarily builds upon our experience in building distributed workflow management for multi-organizational processes. Effective and efficient Quality of Service (...

A key challenge for Next Generation Networks (NGN) is providing support for the negotiation and dynamic adaptation of Quality of Service (QoS) parameters. In this paper we propose a novel QoS Matching and Optimization Function (Q-MOF) to be included along the signaling path with the purpose of providing advanced service-level QoS matching and optimization logic for multimedia services being del...
