Explosive development of multimedia services in actual data networks and the increasing demand for service quality stimulate the interest in the QoS management research. In order to ensure the service quality for multimedia flows crossing heterogeneous domains several resource management entities should cooperate to fulfill this task. In this paper we will present a QoS management system for WiMAX...
This paper presents the validation of an end-to-end QoS integrated management system in a multidomain test-bed environment. The integrated management system was designed and implemented in the framework of the ENTHRONE European project. This paper focuses on the network service management validation at both the Service Provide and Network Provider The Network Service Management is based the SLS management:...
Multimedia flows transport over multiple IP domains requires quality of services (QoS) guarantees. In multi-domain contexts, the end-to-end QoS assurance needs cooperation of several resource management entities. Cooperation of the domains but also preservation of each domainpsilas autonomy are both required. This paper presents results on functional validation of a multiple domain overlay-developed...
Development of multimedia services, e.g. video on demand or IPTV and their flow transport over the IP multi-domain networks with quality of services (QoS) guarantees require appropriate management and control of QoS at service and also at the network level. The management and control system must first support cooperation between several independent network domains at service provisioning level while...
The transport of multimedia flows over the internet needs to manage and control end to end quality of services (QoS) at transport level. Open issues still exist related to finding and maintaining QoS enabled paths through one or several independently administered domains. Among others, two tasks need to be solved: QoS routing or QoS enabled path finding and then maintaining these paths during data...
The multimedia services over the Internet rapid development require QoS management solutions to be implemented in the actual networks. The Internet traffic is now mostly best effort. Additional QoS control mechanisms need to be defined for data networks to be able to offer high quality multimedia services like video on demand or IPTV. Such mechanisms are QoS routing, resource reservation, admission...
Delivery of multimedia real time flows over multi-domain IP networks require end-to-end quality of service guarantees. In order to manage and control the high-level services (video on demand, IPTV, etc.) as well as the network connectivity services across multiple domains in a coherent way, a distributed but integrated management system is proposed. Such a system has been defined, specified, and is...
