PINC: Design and Implementation of Inter-Flow Network Coding in P4-enabled Networks

To support real-time end-to-end reliability, we design and implement a Programming Protocol-independent Packet Processors (P4) based inter-flow network coding (PINC) procedure. PINC utilizes the programmability of P4 so that packets can be dynamically processed in react to the change of network environment. This work aims to show the packet processing by enabling inter-flow network coding. The performance and the the potential utilizing inter-flow network coding in P4 switches for end-to-end packet delivery will also be discussed.
