“…In ENTHRONE, the whole content delivery chain is considered, including three distinct providers: the CP, the network provider, and the service provider. Note that this section assumes that the functionality of the core IMS modules (i.e., P-CSCF, I-CSCF, S-CSCF, AS, HSS, BGCF, MGCF, and MRFC) is known and it focuses only on the offered service management extensions by the corresponding EMS modules [7]. Initially the SP establishes a pSLA (Provider Service Level Agreement) contract with one or several CPs for obtaining the access rights to DIs and for offering these contents to its customers.…”

SUMMARYOriginally defined by the Third Generation Partnership Project (3GPP) as part of its standardization work for 3G mobile phone systems, the IMS model has been adopted as a baseline technology for network and service convergence by network (wireless, wireline and cable), service and content operators. Dealing with the same business actors, the ENTHRONE project (FP6-IP-507637) builds an MPEG-21-based service management system that enables distribution of audio-visual content with dynamic end-to-end QoS guarantees over heterogeneous networks to various types of terminal devices. This system controls the access of users to the content and supervises the delivery of the content to ensure the level of QoS. The paper examines how the IMS model could be extended to include service management features offered by the ENTHRONE management system. These features could constitute a potential vehicle for the IMS entrance to the audio-visual market chain.

This paper further refines the architecture and design, introduced in a previous work on the management and control, of the IEEE 802.16/WiMAX access in a multi-domain chain of IP core networks. The high level objective is to manage end-to-end connectivity services in an integrated way, at overlay level, assuring guaranteed QoS for multimedia delivery over networks with heterogeneous access. Flexible solutions are proposed for integration of the WiMAX service flows management and control within an Integrated Management System (EIMS) developed in the ENTHRONE 1 FP6 project.

“…However, QoS-aware distributed systems impose more challenges in terms of dynamic load balancing, because QoS-aware load balancing techniques in a dynamic service oriented DVE, rely highly on effective service composition and management. Much research has been conducted in terms of QoS-aware service composition and management, including [14][15][16][17][18]. Indeed, how to measure the QoS-aware load balancing algorithms or schemes accurately and effectively, is becoming a major concern in DVE design; and traditional simulations generally cannot effectively handle the dynamic circumstance of such algorithms: for instance, adaptive algorithms in P2P based DVE, with variable task incoming rates and variable participating entities.…”

Distributed Virtual Environment (DVE) has attracted much attention in recent years due to the rapid advances in the areas of E-learning, Internet gaming, humancomputer interfaces, and etc. However, the complexity of designing an efficient DVE greatly challenges today's researchers. Indeed, how to effectively measure a DVE or the design of DVE plays an important role in progressively guiding the DVE design. Meanwhile, the performance of protocols and schemes used in an existing DVE cannot be easily measured straightforwardly. Traditionally, simulation tools are involved to predict the performance of the DVE system or any used protocols; however, existing tools have limited capabilities in terms of accurately capturing the real-world performance. This is due to the statically configured simulations, hard-to-model hardware devices (such as haptic devices, mobile devices), single processor's execution of the simulations, and etc. Moreover, there exists no integrated simulating and measuring framework that can effectively support model reuse, dynamic reconfiguration of a simulation, real devices in the simulation loop (statically or run-time), and distributed simulation execution, just to name a few. In this paper, we propose and implement an integrative simulation and measuring framework; in particular, we design a generic real-time service oriented virtual simulation system which can effectively measure the real time performance of distributed virtual environments and virtual reality based applications. The main goal of our proposed framework lies in providing accurate and near-real-world measurements of a DVE and any related protocols, so that a highly cost-efficient DVE system design can be achieved. Moreover, our framework uses the Experimental Frame concept to separate simulation services from design models so that model reuses, model formalization and model validation can all be done within one layer. The idea of using experimental frame also makes possible a hardware-in-the-loop type of simulation, which is quite useful in DVE including haptic virtual environment, sensor network based virtual environment, and etc. As a case study, we investigate a QoS-aware adaptive load balance algorithm using our framework; and our real-time simulation results clearly indicate that the algorithm outperforms others in a near real-world scenario.
