There are a large class of network optimisation papers that begin (in subtext) with "And God gives you a traffic matrix". These matrices form the basic input to the optimisation, but they are not at all easy to obtain. Today, it's possible to measure your Internet traffic with tools such as Netflow, but the traffic matrix requires more than just traffic data; it requires a synthesis of traffic + routing + topology, so its still uncommon to see real instances. This talk will describe the history of exploration of these complex beasts in the Internet, their measurement, inference, and application. And we'll talk about our most recent work on modelling these using Maximum Entropy methods, to provide techniques for the research community to use to generate synthetic traffic matrices.
Prof. Matthew Roughan is a Professor in the School of Mathematical Sciences at the University of Adelaide, in South Australia and a Chief Investigator in the ARC Centre of Excellence for Mathematical & Statistical Frontiers (ACEMS). His research interests range from stochastic modelling to measurement and management of networks like the Internet. He has worked with network operators such as AT&T in the United States, and equipment vendors such as Ericsson.
The Transmission Control Protocol (TCP) is used by the vast majority of
applications to transport their data reliably across the Internet and in the
cloud. TCP was designed in the 1970s and has slowly evolved since then. Today's
networks are multipath: mobile devices have multiple wireless interfaces,
datacenters have many redundant paths between servers, and multihoming has
become the norm for big server farms. Meanwhile, TCP is essentially a
single-path protocol: when a TCP connection is established, the connection is
bound to the IP addresses of the two communicating hosts and these cannot
change. Multipath TCP (MPTCP) is a major modification to TCP that allows
multiple paths to be used simultaneously by a single transport connection.
Multipath TCP circumvents the issues mentioned above and several others that
affect TCP. The IETF published the Multipath TCP RFC in January 2013 and an
implementation in the Linux kernel is available today from
This tutorial will present in details the design of Multipath TCP. We will start with a presentation of the current Internet landscape and explain how various types of middleboxes have influenced the design of Multipath TCP. Second we will describe the key design choices for the connection establishment and release procedures as well as the data transfer mechanisms. We will then discuss several use cases for the deployment of Multipath TCP including improving the performance of datacenters, mobile WiFi offloading on smartphones and IPv4/IPv6 coexistence.
Olivier Bonaventure is Professor at Université catholique de Louvain where he leads the IP Networking Lab (http://inl.info.ucl.ac.be). His research interests include Internet protocols, traffic engineering, routing Internet measurements and network management. He is interested in both fundamental and applied research. His PhD students have developed several open-source software packages including the C-BGP simulator, OpenLISP and the shim6, Multipath TCP and IPv6 Segment Routing implementations in the Linux kernel. He has published more than eighty papers in various scientific journals and conferences and has directed ten PhD thesis. He also contributes to the IETF and has been granted several patents. Olivier Bonaventure received several awards as a researcher (Alcatel-Bell prize, INFOCOM 2007 best paper award, USENIX NSDI 2012 community award) and teacher (Wernaers prize for the development of online courses, Saylor.org prize for the open textbook Computer Networking : Principles, Protocols and Practice). He currently serves as editor for SIGCOMM Computer Communication Review.
Version 2 of the Hypertext Transfer Protocol (HTTP/2) was finalized in May 2015 as RFC 7540. It addresses well-known problems with HTTP/1.1 (e.g., head of line blocking and redundant headers) and introduces new features (e.g., server push and content priority). Though HTTP/2 is designed to be the future of the web, it remains unclear whether the web will (or should) hop on board. To shed light on this question, we built a measurement platform that monitors HTTP/2 adoption and performance across the Alexa top 1 million websites on a daily basis. Our system is live and up-to-date results can be viewed at http://isthewebhttp2yet.com. In this lecture, I will first introduce H2 and the results obtained via our measurement infrastructure. Next, I will discuss the lessons learned along with a set of challenges common across network measurements.

Internet-scale Experimentation is a seminar exploring the challenges of
large-scale networked system experimentation and measurements. Over the last
few decades, networked systems have become an integrated part of everyday life
and a critical piece of our economic, educational, health and defense systems.
This fact is normally brought up as evidence of the success and broader impact
of our field of work.
The other, typically avoided, side of the story is the complications that this translates into for experimentalists. Today it is virtually impossible to run a randomized controlled experiment at even fractions of the scale of many of our systems. Despite this, as we explore new ideas in these uncharted territories we are reasonably asked to provide better evidence of the effects of interventions. In this course we will discuss recent and ongoing on networked systems experimentation and their applications that address some of the key challenges.

The purpose of this program is to encourage graduate student participation at the TMA PhD School by funding the travel costs (or part thereof) for students who otherwise would be unable to attend.
• A résumé with complete contact information and correct email address.
• A short personal statement (1 or 2 paragraphs, no more than 1 page) that includes information that the applicant feels is relevant to support his/her case, e.g., why the PhD School attendance is important to the applicant's research and career development. It must include the estimated expenses for attending the TMA PhD School (total, and breakdown by travel and lodging) and an indication of which cost items would need to be covered by the grant. If you will be unable to attend the School without a travel grant, please explain why this is the case.
• A letter from your adviser, which should: (i) confirm the applicant's good standing in the institution; (ii) explain why the applicant would benefit from attending the TMA PhD School; and (iii) explain the current funding status and why the applicant is in need of the travel grant. This adviser's letter can be sent to firstname.lastname@example.org if your adviser prefers.
Application Deadline: February 15, 2016, 23:59 CET
Decision Notification: February 22, 2016
Late applications will not be considered. All the above documents must be submitted by the deadline.
Please pay attention to the following details about the student travel grant application and reimbursement process:
• You must be a PhD student at the time of attending the TMA PhD School to qualify for a travel grant.
• We expect a student travel grant will significantly offset registration, air fare and shared hotel accommodation. It may not fully cover these expenses, however, since our desire is to maximize participation by students. In order to obtain reimbursement, you must provide original receipts for air fare and hotel expenses, along with boarding passes (plane or train) for both outbound and inbound journeys.
• All students participating in the School are required to present a poster describing his/her research and to actively engage with all activities. Failing to do so will lead to grant cancellation.
• Please provide complete contact information. You will be notified via email, so make sure your email address is correct on your application.
• The reimbursement process can take some months. The decision on student travel grants is made by the PhD School Organizing Committee. All decisions are final.
Only students that are awarded a grant should follow these instructions. The contact persons for the reimbursement of travel costs are:
