IMS has been widely recognized as the control and signaling framework for delivering of the rich communication and multimedia services to the broadband users. Amongst others, it is deployable as the service (middleware) platform for the interactive and personalized IPTV services. The goal of this paper is to provide an investigation of the advanced use(More)
This article presents the architecture design and experimental evaluation of a QoE-aware flexible-QoS-control next-generation IPTV network. The architecture extends the IMS service control functionality by providing an efficient application-specific service control approach based on user satisfaction on the connectivity. The validation NGN testbed uses(More)

Modern wireless networks, such as WiMAX or LTE are using OFDM/OFDMA as the enabling technologies for broadband transmission in cellular environments with QoS capabilities. In these networks, such schema as radio resource management, admission control, scheduling are essential. In this article we firstly introduce a Time-Frequency Burst Mapping algorithm for(More)
IMS-based IPTV is the next generation IPTV architecture that makes use of the advanced NGN functionalities to provide novel, interactive and blending IPTV services. It can also facilitate QoS guarantee based on the existing IMS service control capabilities. In the article, we propose a new architecture and the corresponding mechanisms to extend the service(More)
IMS has been widely recognized as the control and brokering framework for delivering of the blended communication and multimedia services to the fix and mobile IP users. However, until recently, most of IMS services have been developed and deployed in a manner that does not carefully consider how these services can be combined and interact with each other(More)
ICT is currently responsible for 4% of the EU's carbon emission. In this industry, data centers are growing quickly to supply the escalating services and application demands. The design of high performance and energy-efficient data center networks is an important issue while still being confronted with many challenges such as scalability, reliability, etc.(More)
Nowadays, Distributed Denial of Service (DDoS) attacks get the most attention since volumetric attacks saturate company's networks and associated server infrastructure. In fact, DDoS can occur weekly or daily in a network but many organizations have no systems in place to monitor DDoS traffic so as to be aware if their networks are being attacked. Within(More)
