A programmable networking switch node with in-network processing support

As the heterogeneity of end devices and their networked applications grows, networking challenges should be coped with new features to meet the various requirements of different application traffics. In this paper, based on the emerging SDN (Software-Defined Networking) paradigm, we introduce NetOpen networking services that attempt to support configurable networking with programmable networking switch nodes. Especially, we prototype a NetOpen switch node to support customized in-network processing and verify its programmability and in-network processing performance for multiple flows.
