| | 3 | 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.[[BR]] |
| | 4 | 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.[[BR]] |
| | 5 | In 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. |

| | 19 | Using 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]] |
| | 20 | After 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. |
