FlowOS: A pure flow-based vision of network traffic

The original Internet architecture lacked the concept of a flow, and considered each traffic as a set of packets. In this short paper, we rethink this concept inside middlebox-based platform and handle each traffic as a whole block instead of packets. We design a whole system where each input packet matching some criteria is placed in a specific structure which is shared between all processing modules that interact in a parallel manner with this flow. Thus, this new design improves flexibility of traffic and also increases the flow processing performances.
