A lightweight algorithm for traffic filtering over sliding windows
Sanjuàs Cuxart, Josep; Barlet Ros, Pere; Solé Pareta, Josep; Andriuzzi, Gabriella (2012)
Text en actes de congrés
Accés restringit per política de l'editorialThe problem of testing whether a packet belongs to a set of filtered addresses has been traditionally addressed using Bloom filters. They have a small memory footprint and require few memory accesses per query and insertion, ... -
A practical approach to portscan detection in very high-speed links
Mikians, Jakub; Barlet Ros, Pere; Sanjuàs Cuxart, Josep; Solé Pareta, Josep (Springer Verlag, 2011)
Text en actes de congrés
Accés restringit per política de l'editorialPort scans are continuously used by both worms and human attackers to probe for vulnerabilities in Internet facing systems. In this paper, we present a new method to efficiently detect TCP port scans in very high-speed ... -
Cuckoo sampling: robust collection of flow aggregates under a fixed memory budget
Sanjuàs Cuxart, Josep; Barlet Ros, Pere; Duffield, Nick; Kompella, Ramana (Institute of Electrical and Electronics Engineers (IEEE), 2012)
Text en actes de congrés
Accés restringit per política de l'editorialCollecting per-flow aggregates in high-speed links is challenging and usually requires traffic sampling to hand le peak rates and extreme traffic mixes. Static selection of sam pling rates is problematic, since ... -
Efficient algorithms for passive network measurement
Sanjuàs Cuxart, Josep (Universitat Politècnica de Catalunya, 2012-03-23)
Tesi
Accés obertNetwork monitoring has become a necessity to aid in the management and operation of large networks. Passive network monitoring consists of extracting metrics (or any information of interest) by analyzing the traffic that ... -
Network Polygraph: An innovative network visibility service (not only) for NRENs
Barlet Ros, Pere; Sanjuàs Cuxart, Josep; Solé Pareta, Josep; Gandía, Maria Isabel; Malagón, Chelo (2015)
Comunicació de congrés
Accés obertWe present Network Polygraph (https://polygraph.io), a network monitoring service based on NetFlow/IPFIX that benefits from more than 10 years of research in the fields of network monitoring and traffic classification at ... -
Skettching the delay: tracking temporally uncorrelated flow-level latancies
Sanjuàs Cuxart, Josep; Barlet Ros, Pere; Duffield, Nick; Kompella, Ramana (2011)
Text en actes de congrés
Accés restringit per política de l'editorialPacket delay is a crucial performance metric for real-time, network-based applications. Obtaining per-flow delay measurements is particularly important to network operators, but is computationally challenging in high-speed ...
