TL;DR: This paper presents both analytical results and experimental evaluation of measurement error due to network delay between the SDN switches and the controller, and proposes to extend the OpenFlow protocol with a local timestamping mechanism.

TL;DR: A deep analysis of these infrastructures for the two public-cloud leading providers: Amazon Web Services and Microsoft Azure is proposed and shows that Azure inter-datacenter infrastructure performs better than Amazons in terms of throughput (+56%, on average).

TL;DR: This work investigates some of the solutions, based on machine learning models as well as tools and architectures for Big Data analysis that can be exploited in the astrophysical context.
Abstract: Nowadays there is no field research which is not flooded with data. Among the sciences, Astrophysics has always been driven by the analysis of massive amounts of data. The development of new and more sophisticated observation facilities, both ground-based and spaceborne, has led data more and more complex (Variety), an exponential growth of both data Volume (i.e., in the order of petabytes), and Velocity in terms of production and transmission. Therefore, new and advanced processing solutions will be needed to process this huge amount of data. We investigate some of these solutions, based on machine learning models as well as tools and architectures for Big Data analysis that can be exploited in the astrophysical context.

TL;DR: Six novel measurement techniques based on IP options are presented, showing how IP options can still offer unforeseen ways to augment the knowledge about networks, potentially presenting both new threats and new opportunities for different stakeholders.
Abstract: Injecting purposely-created probing traffic makes it possible to detect the presence and location of performance issues or faults, to reveal the topology of the network, and to investigate related properties. While researchers and network operators still rely on traditional tools (e.g., traceroute or ping) to shed light on the Internet, here we present six novel measurement techniques based on IP options. We show how IP options can still offer unforeseen ways to augment the knowledge about networks, potentially presenting both new threats and new opportunities for different stakeholders.
