Brief demo description: Demonstration of wide-band radio transceiver for the GENI CogRadio system. The demonstration will highlight the WDR (Wide Dynamic Range) radio operating on an FPGA platform. Signal analyzers will demonstrate the system operating at 100MHz, 400MHz, 900Mhz and 2400MHz on a combination of cabled connections (for licensed bands) and free space (for unlicensed bands). The demonstration will also include a poster detailed the software infrastructure employed.

We would like to present one normal-size poster at the GEC13 about the Adaptive Source Routing of the University of Illinois at Urbana-Champaign. The primary investigator is Professor Brighten Godfrey. This is the project's description:

Today's routing techniques on the Internet rely completely on decisions within the network. Lacking an end-to-end view, routing algorithms therefore often react slowly to dynamics in the network, and do not take into account the type of traffic being routed. For example, traffic with the demand of high bandwidth is not distinguished from services needing low latency such as real-time applications.

This project is investigating the alternate approach of source-controlled routing (SCR). Assuming a source node holds information about possible routes to destination nodes including information about the characteristics of the different paths obtained by continuous probing, a source can decide which path along the network a particular packet should traverse for optimal results. In addition to that, multipath routing can be used to dramatically decrease latency and routing-related delay with a reasonable overhead on traffic when sending packets simultaneously via different links, using only the packet which arrives first at the destination.

Previously, we have presented at GENI results of measurements of the effectiveness of SCR in a PlanetLab overlay network, as well as a simple demo of the technique on GENI's OpenFlow network. This poster will present measurements of SCR in GENI's OpenFlow network, and will compare them with our conclusions on PlanetLab. In particular we are measuring the effectiveness of various path selection algorithms and multipath strategies, leveraging the GENI OpenFlow network to decrease unpredictability in the previously used overlay deployment. Our results from the overlay deployment and first results from the GENI topology show that the latency-distribution's tail can be significantly decreased when using source-controlled routing with different path-selection strategies.

Brief demo description

Demo Participants: Andy Bavier, Princeton University

We will demonstrate a web-based resource management tool called MySlice, which makes it easy to list, filter and attach resources made available through PlanetLab’s SFA control framework, annotated with useful information from different monitoring sources (e.g., reliability and utilization over time, geographic and network location, and more).

Features of MySlice:

• MySlice uses SFA’s delegation capabilities to permit an SFA client to run on a remote webserver.
• Resources can be selected using measurement data gathered from a number of independent measurement and monitoring projects, including TopHat, CoMon, and SWORD

Elements of MySlice are already in use as part of the standard PlanetLab web interface, used by hundreds of users.

This work is a product of the international cooperation between Princeton University, the University of Tokyo, and UPMC Sorbonne Universites. It was funded in part by GENI’s “Understanding Federation” grant. It takes place in the context of the global PlanetLab federation involving PlanetLab Central, PlanetLab Europe, and PlanetLab Japan.

This work has also received support from the European Community's Seventh Framework Programme (FP7/2007-2013) under grant agreement n°224263 - !OneLab2.
