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)
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)
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 realtime replica placement) lack placement and retrieval algorithms that are both intelligent and scalable. In this paper we(More)
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)
Because of the ever-increasing popularity of the Internet, network monitoring becomes very mission critical to guarantee the operation of IP networks, e.g. to detect network failures and stop intrusion attempts. A majority of these monitoring tasks require only a small subset of all passing packets, which share some common properties such as identical(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)
In the last decade, the OSPF routing protocol has proven its robustness, but it also has some major drawbacks. It reacts quite slowly to network changes, and load balancing is limited to paths with equal cost (ECMP). In this paper, we present our implementation and evaluation of an alternative: AntNet [1]. AntNet is a distributed shortest-path algorithm(More)
