摘要： A gateway is provided that handles traffic in and out of a network by using a datapath pipeline. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.

摘要： A novel design of a gateway that handles traffic in and out of a network by using a datapath pipeline is provided. The datapath pipeline includes multiple stages for performing various data-plane packet-processing operations at the edge of the network. The processing stages include centralized routing stages and distributed routing stages. The processing stages can include service-providing stages such as NAT and firewall. The gateway caches the result previous packet operations and reapplies the result to subsequent packets that meet certain criteria. For packets that do not have applicable or valid result from previous packet processing operations, the gateway datapath daemon executes the pipelined packet processing stages and records a set of data from each stage of the pipeline and synthesizes those data into a cache entry for subsequent packets.
