FlexNIC: Rethinking Network DMA

  title={FlexNIC: Rethinking Network DMA},
  author={Antoine Kaufmann and Simon Peter and Thomas E. Anderson and Arvind Krishnamurthy},
We propose FlexNIC, a flexible network DMA interface that can be used by operating systems and applications alike to reduce packet processing overheads. The recent surge of network I/O performance has put enormous pressure on memory and software I/O processing subsystems. Yet even at high speeds, flexibility in packet handling is still important for security, performance isolation, and virtualization. Thus, our proposal moves some of the packet processing traditionally done in software to the… CONTINUE READING
