The concept of service oriented architecture has been extensively explored in software engineering, due to the fact that it produces architectures made up of several interconnected modules, easy to reuse when building new systems. This approach to design would be impossible without interconnection mechanisms such as REST (Representational State Transfer)(More)
The size and complexity of cloud environments make them prone to failures. The traditional approach to achieve a high dependability for these systems relies on constant monitoring. However, this method is purely reactive. A more proactive approach is provided by online failure prediction (OFP) techniques. In this paper, we describe a OFP system for private(More)
Keywords: Network convergence Multimedia services Quality of service The emerging use of real-time 3D-based multimedia applications imposes strict quality of service (QpS) requirements on both access and core networks. These requirements and their impact to provide end-to-end 3D videoconferencing services have been studied within the Spanish-funded VISION(More)
Multimedia multiparty applications on the Internet are commonly supported by specific servers containing all the required functionalities in a centralized manner. The IP Multimedia Subsystem (IMS) is the current paradigm of the Next Generation Network (NGN) model. It provides a set of basic service enablers and functions beyond IP connectivity, such as(More)
