Descripción del proyecto
Network monitoring and measurement is increasingly regarded as an essential function for developing and supporting high-quality networkservices, building and improving innovative networking technologies, analyzing infrastructure trends and user behavior, and improving the security of our cyber-infrastructure. Accurate network monitoring systems give rise to a wide variety of new applications including provision of early warning for the detection of Internet worms as soon as they start to spread,detection of Distributed-Denial-of-Service attacks even before they are launched, accurate traffic characterization even for applications that use dynamically generated ports such as peer-to-peer systems, and accurate traffic weather service for GRID-enabled applications. Although accurate network monitoring is getting increasingly important for the reliable and efficient operation of our cyber-infrastructure, current traffic monitoring systems in Europe do not provide the information needed to support the above-mentioned applications. Indeed, current systems focus either on collecting lossy flow-level statistics, or in actively measuring latency, bandwidth, error rate and similar properties of network links. In LOBSTER we propose to design and deploy a advanced European Infrastructure for accurate Internet traffic monitoring. Although such an infrastructure poses challenging research questions, we believe that we have successfully met these challenges within the currently running SCAMPI IST FP5 project, that designed and developed a passive network traffic monitoring system for speeds up to 10Gbps. Based on passive monitoring, and capitalizing on ourexperience gained in the SCAMPI IST project, the LOBSTER infrastructure will be unique in Europe and among the only two similar infrastructures that exist in the world today.
