Abstract
A novel design of a gateway that handles traffic in and out of a network by using a datapath daemon is provided. The datapath daemon is a run-to-completion process that performs various data-plane packet-processing operations at the edge of the network. The datapath daemon dispatches packets to other processes or processing threads outside of the daemon. Datapath operations at lower layers of the network protocol model are processed by the datapath daemon within its run-to-completion thread, while datapath operations at higher layers of the network protocol model are processed by data plane processes external to the datapath daemon.
