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. The method inserts TLR identifiers as VLAN tags into the dispatched packets from the datapath daemon so that the network stack can deliver them to the correct TLR-specific namespace.
