An Analysis of BitTorrent Cross-Swarm Peer Participation and Geolocational Distribution
Peer-to-Peer (P2P) file-sharing is becoming increasingly popular in recent
years. In 2012, it was reported that P2P traffic consumed over 5,374 petabytes
per month, which accounted for approximately 20.5% of consumer internet
traffic. TV is the popular content type on The Pirate Bay (the world's largest
BitTorrent indexing website). In this paper, an analysis of the swarms of the
most popular pirated TV shows is conducted. The purpose of this data gathering
exercise is to enumerate the peer distribution at different geolocational
levels, to measure the temporal trend of the swarm and to discover the amount
of cross-swarm peer participation. Snapshots containing peer related
information involved in the unauthorised distribution of this content were
collected at a high frequency resulting in a more accurate landscape of the
total involvement. The volume of data collected throughout the monitoring of
the network exceeded 2 terabytes. The presented analysis and the results
presented can aid in network usage prediction, bandwidth provisioning and
future network design.Comment: The First International Workshop on Hot Topics in Big Data and

Quality of service assurance for the next generation Internet
The provisioning for multimedia applications has been of increasing interest among researchers and Internet Service Providers. Through the migration from resource-based to service-driven networks, it has become evident that the Internet model should be enhanced to provide support for a variety of differentiated services that match applications and customer requirements, and not stay limited under the flat best-effort service that is currently provided.
In this paper, we describe and critically appraise the major achievements of the efforts to introduce Quality of Service (QoS) assurance and provisioning within the Internet model. We then propose a research path for the creation of a network services management architecture,
through which we can move towards a QoS-enabled network environment, offering support for a variety of different services, based on traffic characteristics and user expectations
Multi-Terabit/s IP Switching with Guaranteed Service for Streaming Traffic
traffic on the Internet continues to grow exponentially, there is a real need to solve transmission and switching scalability. Moreover, future Internet traffic will be dominated by streaming media flows, such as video-telephony, video-conferencing, 3D video, virtual reality, and many more. Consequently, network solutions will need to offer quality of service and traffic engineering together with the above mentioned scalability - i.e., over-provisioning is not likely be a viable solution to accommodate streaming media traffic. This paper describes the architecture of a ultra-scalable IP switch and the first experiments with a prototypal implementation. The switch scalability is a consequence of it operating pipeline forwarding of packets, which also results in quality of service guarantees for UDP-based streaming applications, while preserving elastic TCP-based traffic as is, i.e., without affecting any existing applications based on "best- effort" services. Moreover, the prototype demonstrates the low complexity of pipeline forwarding implementation as the deployed network gear was realized from off-the-shelf components in only nine months through the design, implementation, and testing efforts of the authors
