On December 4th, 2014, IMDEA Networks and Telefonica, in collaboration with the SEPI Foundation, launch a new edition of the Talentum Startups program

Information overload has become an ubiquitous problem in modern society. Social media users and microbloggers receive an endless flow of information, often at a rate far higher than their cognitive abilities to process the information.

The performance of the global routing system is vital to thousands of entities operating the Autonomous Systems (ASes) which make up the Internet. The Border Gateway Protocol (BGP) is currently responsible for the exchange of reachability information and the selection of paths according to their specified routing policies.

Only a year ago Spaniards began to enjoy 4G mobile networks, which increase tenfold the transmission rates of mobile data when compared to the third generation.  5G network development is now underway, intent on providing a network with a capacity one thousand times higher than the previous generation.

The Internet's Transport Layer has been defined by TCP and UDP for the last 30 years. The minimal functionality of UDP enables application developers to develop their own proprietary protocols – there are plenty of examples.

Context-awareness is a peculiar characteristic of an expanding set of applications that make use of a combination of restricted spatio-temporal locality and mobile communications, to deliver a variety of services. Opportunistic communications satisfy well the communication requirements of these applications, because they naturally incorporate context.

The Internet is a messy, complex landscape. Middleboxes such as DNS resolvers, UPnP home gateways, and in-path proxies placed in the IP core of the operators' networks can significantly impair a user's access despite being designed for the contrary.

The International Symposium on DIStributed Computing (DISC) is an international forum on the theory, design, analysis, implementation and application of distributed systems and networks. It is organized in cooperation with the European Association for Theoretical Computer Science (EATCS). This conference, in collaboration with PODC (the ACM Symposium on Principles of Distributed Computing), awards annually the highly recognised Edsger W. Dijkstra Prize in Distributed Computing and The Dissertation Award in Distributed Computing.

The IFIP Performance conference aims to bring together researchers interested in understanding and improving the performance of communication systems by means of state-of-the-art quantitative models and solution techniques.

This paper presents a simple framework, called WalkAbout, to infer a coarse view of connectivity in very large graphs; that is, identify well-connected “regions" with different edge densities and determine the corresponding inter- and intra- region connectivity.
