Adding a Flow-Oriented Paradigm to Commodity Operating Systems

Soviani, Cristian; Edwards, Stephen A.; Keromytis, Angelos D.

The speed of CPUs and memories has historically outstripped I/O, but emerging network and storage technologies promise to invert this relationship. As a result, fundamental assumptions about the role of the operating system in computing systems will have to change. We propose an operating and application architecture that removes the CPU and memory from the path of high-speed I/O. In our model, the operating system becomes a data-flow manager and applications merely direct this flow instead of directly participating in it. Our proof-of-concept prototype, which we implemented on an FPGA board, nearly doubled the throughput of a simple cryptographic networking application, suggesting our model can provide a substantial improvement.
