RIPE Atlas: An Active Measurements Network
Serge Radovcic, RIPE NCC
Begun in 2010, RIPE Atlas embodies the next generation of active Internet measurement tools. It consists of a network of small, easily deployable probes which are designed to perform continuous measurements on reachability. By the end of 2011, 1024 probes were contributing to the aggregate picture of core internet connectivity around the world. The information the Atlas network provides is valuable not only to organizations in the RIPE service region: comprehensive data benefits the entire community by revealing both short-term problems and longer-term inefficiencies in routing infrastructure. User Defined Measurements add an additional dimension of benefit to probe hosts and sponsors by enabling self-defined measurements from any set of RIPE Atlas probes.

Methods for Optimizing Data Capacity
Yair Shapira; Hayim Shaul, DiViNetworks
In this talk we present the various methods for optimizing data capacity - transparent caching, CDN, traffic shaping, and video compression. We present a novel method for virtually generating capacity from the cloud, explaining the underlying algorithms and the surprising information-theory basis for traffic redundancy. We will share real network traffic analysis. An ISP applying this methodology may be co-presenting. The audience will learn of the various optimization mechanisms available, their pros and cons, and specifically will learn the details of the novel virtual capacity approach.
