A programmable data plane that supports definable computing

For current Internet is confronted with some defects such as structural rigidity, single function, and protocol-independent, the functions, performance and efficiency of the Internet were promoted from the perspective of the data plane, it proposes to support computing definable programmable data based on the full-dimensional defined polymorphic smart network. It uses in-network calculations to offload network functions to programmable network elements (programmable switches) to improve operational efficiency and flexibility. This article first uses the protocol-independent P4 language to realize the definable forwarding of the data plane; on this basis, a new forwarding model is designed, adding calculation functions that are not originally supported by P4, and the calculation is definable; finally, DES encryption is used as the calculation Function verification, and think and discuss the experimental process.
