In this paper, a method for enhancing current QoS routing methods by means of QoS protection is presented. In an MPLS network, the segments (links) to be protected are predefined and an LSP request involves, apart from establishing a working path, creating a specific type of backup path (local, reverse or global). Different QoS parameters, such as network load balancing, resource optimization a...

Approaches to a functional and a computational architecture for distributed multimedia presentational applications are developed. These approaches are illustrated by a case study, a multimedia news-on-demand service. The concept of Quality of Service (QoS) parameters is seen to determine the new characteristics of distributed multimedia applications. Accordingly the computational architecture f...

Ad hoc mobile networking is a current active research area. They can be used in agriculture for monitoring and control of environmental parameters in the form of wireless sensor networks. The aim of this paper is performance evaluation of protocol of these Ad hoc networks i.e. QoS-enabled AODV protocol. The performance evaluation is done by means of its comparison with normal AODV protocol. QoS...

This paper proposes to integrate security parameters into the Service Level Specification (SLS) template proposed in the Tequila project to improve SLA-based management of QoS [8, 21]. Integrating those parameters in the QoS part of the Service Level Agreement (SLA) specification is essential in particular for secure multimedia services since the QoS is negotiated when the multimedia service is...

—A cross-layer based QoS optimization algorithm for wireless traffic networking is presented in this paper. In terms of the fuzzy measure theory, we propose a nonlinear wireless traffic networking optimization model based on the Choquet integral. The model can characterize not only the protocol parameters’ significance but also the interdependency among those parameters on the QoS of data tran...

In this paper, a field test platform called OTTCAP (OTT Services Capture and Analyze Platform) is developed for capturing and analyzing QoS (Quality of Service) and QoE (Quality of Experience) parameters of OTT (over-the-top) services in HSPA+ (Evolved High Speed Packet Access) networks, including Network-Level and Application-Level QoS parameters, terminal parameters and wireless environment p...

In this paper we describe the design of a QoS driven communications stack in a microkernel operating system environment. The paper focuses on resource management aspects of the design and in particular we deal with CPU scheduling, network resource management and memory management issues. We describe an API at which QoS parameters are supplied by users and present an architecture able to guarant...
