In this paper we provide an overview of the signaling system that we implemented in the IPv6 QoS Parallel Internet. This Parallel Internet has been proposed as one of Parallel Internets of the IIP System developed in scope of Future Internet Engineering project. The aim of the signaling system of the IPv6 QoS Parallel Internet is to perform call setup/release for assuring end-to-end QoS (Quality of...
The inter-domain QoS control employing a session-based resource management capability of next generation networks (NGN) is demonstrated for the first time. For a video-on-demand application, the extended resource and admission control function (RACF) is applied and the resource reservation over different NGN-domains is successfully conducted.
Next generation wireless systems represent an heterogeneous environment encompassing different radio access network technologies (RATs) that differ in bandwidth, latency or cost. At the same time, mobile devices can now support multiple radio network interfaces and are therefore able to select from various available multiple heterogeneous access networks the most appropriate one in order to satisfy...
This paper presents a Model of Quality of Service (QoS) for Next Generation Networks (NGN), that consist of a tower of five defined layers such as the Model Layer of QoS, Control of Admission, QoS in the Routing, QoS in the Signaling, and MAC QoS. In addition, the model raises a method based on the concept of segregation of functions defining two functional networks along with the tasks of QoS. Then,...
Future telecommunication networks are likely designed along the Next Generation Network (NGN) framework of the ITU-T. End-to-end Quality-of-Service support-independent from underlying transport-related technologies-is one of the fundamental requirements of NGNs. This paper presents an overarching QoS control architecture that is based on the IETF's Next Steps in Signaling framework. It provides a...
Quality of Service (QoS) control and resource management in Next Generation Networks (NGN) is provided by a particular architecture called RACF (Resource and Admission Control Function) which has been introduced by ITU. In this paper, we propose a dynamic and scalable policy for RACF to manage the bandwidth reservation for arriving calls. This threshold based method will decrease processing load compared...
Next Generation Networks (NGNs) transport a variety of services across a converged IP-based network infrastructure. To assure the Quality of Experience (QoE) for the users, an end-to-end Quality of Service (QoS) management is required. While solutions for QoS management and admission control in access and core networks exist, the inclusion of the home network remains still open. Thus, we present a...
In this paper we study the call admission control problem to optimize the network operators' revenue guaranteeing the quality of service to the end users. We consider a network scenario where each class of service is characterized by a different constant bit rate and an associated revenue. We formulate the problem as a Semi-Markov Decision Process, and we use a model based Reinforcement Learning approach...
The centralized management of the QoS in NGNs is currently one of the main lines of research in the networking sector. One of the tasks of the ITU-T organisation in this area is to develop a global architecture capable of managing end-to-end services to be used on future specifications. This paper presents a signalling architecture proposal for the end-to-end QoS management conforming the early ITU-T...
This paper analyses the current developments in terms of telecommunication networks design and investigates their limits concerning the control and management of multicast flows. An innovative approach is then introduced to extend the current architectures, so far mainly focused on unicast services, to handle multicast and broadcast services in a heterogeneous networks environment. The proposed solution...
Radio resource management (RRM) in the next generation wireless network system will have features and requirements that are quite distinct from current systems, mostly designed for non-heterogeneous and non-shared networks. Such features include radio resource sharing which is considered as one of the main future issues of RRM as network evolves towards 4G Radio resource sharing has an impact on system...
