According to the Intergovernmental Panel on Climate Change report released in September 2014, unprecedented changes in temperature and precipitation patterns have been recorded globally in recent decades and further change is predicted to occur in the near future, mainly as the result of human activity. In particular, projections show that the Mediterranean(More)
The recent introduction of Content Distribution Networks (CDNs) enhances the delivery of high quality multimedia content to end users. In a CDN architecture, the content is replicated to so-called surrogate servers, generally at the edge of the transport network, to improve the quality of service (QoS) of streaming multimedia delivery services. By using(More)
In this paper we describe the architecture of SCAMPI (A Scaleable Monitoring Platform for the Internet). SCAMPI allows easy writing of monitoring applications, which can run on top of different network adapters without changing the code and which can provide detailed monitoring of high-speed Internet circuits. This is made possible by MAPI (Monitoring API)(More)
— Content distribution networks (CDN) have been increasingly used as the scalable solution to deliver high-quality multimedia content. However, despite the promising concept, current self-organizing content distribution networks (using real-time replica placement) lack placement and retrieval algorithms that are both intelligent and scalable. In this paper(More)
This document describes the enhanced implementation of the SCAMPI monitoring software and the applications. It is the successor of deliverable D2.2 " SCAMPI Prototype Implementation Report " , which focuses on the evolution of the different implemented SCAMPI prototypes. This deliverable elaborates on the detailed implementation of the architecture(More)
Content distribution networks (CDN) have been increasingly used to deliver bandwidth-intensive multimedia content to a large amount of users. In a CDN, the content is replicated from the origin server to so-called surrogate servers in order to improve the quality of service experienced by the end-users and decrease the network load. However, despite the(More)
Currently, a lot of research has been devoted to (i) content distribution, (ii) traffic engineering, (iii) network monitoring and (iv) service enabling platforms. However, the integration of these four individual concepts in a single platform has not yet been studied in enough detail. In this paper we present an architecture for such a robust content(More)
