     3Today'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.[[BR]]
     4This 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.[[BR]]
     5In addition to that, multi-path 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.

     19Using an overlay deployment on PlanetLab, we first tested the general effectiveness of source-controlled routing and different fast-adaption techniques in order to react to path failures quickly. This work was presented at GEC8.[[BR]]
     20After evaluating different path-selection strategies in order to identify well performing paths for different traffic types and metrics, we are currently testing our system and algorithms within the GENI meso-scale OpenFlow testbed. This enables us to minimize unpredictability in the actual path-selection through PlanetLab's overlay-architecture and obtain more accurate performance estimates.
