End-user agnostic join and fork framework for TCP flows in SDN

Aggregating common-path network flows (in the network interior) helps in improving the applications delivery performance. From the network edge perspective, the sender and receiver-ends of the respective applications need to have a typical one-to-one mapping. An aggregation framework in the network therefore needs an effective forking to maintain the one-to-one mapping of the flows. In this demo, we show a working prototype of TCP-based join and fork framework that we have developed and implemented using SDN. Moreover, our framework is implemented in such a way that the aggregation and splitting of flows are performed seamlessly without intervention from the end-user applications. We believe such transparency in the framework would attract existing (unmodified) applications to easily adapt and benefit from our implementation.
