How Far Can We Go in Compute-less Networking: Computation Correctness and Accuracy
share
Emerging applications such as augmented reality and the tactile Internet are compute-intensive and latency-sensitive, which hampers their running in constrained end devices alone or in the distant cloud. The stringent requirements of such application drove to the realization of Edge computing in which computation is offloaded near to users. Moreover, these applications are often executed with similar input data that yield the same output. Compute-less networking is an extension of edge computing that aims at reducing computation and abridging communication by adopting in-network computing and computation reuse. Calculation-reuse aims to cache the result of calculations, and use them to perform similar tasks in the future and, therefore, avoid redundant calculations and optimize the use of resources. Since the input might not be identical but similar, the reuse of previous computation raises questions on the correctness and accuracy of the final results. In this paper, we study the correctness of output data in the computation reuse concept and gauge the effectiveness and efficiency of compute-less networking.
