Abstract: Locality-aware policies for content distribution attempt to redirect content requests to nearby sources in order to optimize bandwidth utilization and reduce operating costs for Internet Service Providers For this purpose, an oracle service is required to track content availability at each location and dynamically redirect requests to an optimal source In this paper we propose an OpenFlow-based locality oracle, developed as a POX controller module in an attempt to make the redirection mechanism as transparent as possible to the underlying service We show two possible implementations, using respectively DNS resolution and HTTP redirection, and we analyze the benefits and downsides of each solution Finally, we evaluate the impact of the redirection process on the latency experienced by the requester

TL;DR: This whitepaper proposes OpenFlow: a way for researchers to run experimental protocols in the networks they use every day, based on an Ethernet switch, with an internal flow-table, and a standardized interface to add and remove flow entries.

TL;DR: Content-Centric Networking (CCN) is presented, which treats content as a primitive - decoupling location from identity, security and access, and retrieving content by name, using new approaches to routing named content.

TL;DR: Content-Centric Networking (CCN) is presented which uses content chunks as a primitive---decoupling location from identity, security and access, and retrieving chunks of content by name, and simultaneously achieves scalability, security, and performance.

TL;DR: The greatest value of Mininet will be supporting collaborative network research, by enabling self-contained SDN prototypes which anyone with a PC can download, run, evaluate, explore, tweak, and build upon.
Taming the torrent: a practical approach to reducing cross-isp traffic in peer-to-peer systems

TL;DR: It is found that the lightweight approach significantly reduces cross-ISP traffic and, over 33% of the time, it selects peers along paths that are within a single autonomous system (AS), and that these high-quality paths can lead to significant improvements in transfer rates.
