  • Automated scaling of packet processing service resources
    Patent number: 12348431
    Abstract: A virtual network interface is configured to receive packets of an application at a packet processing service. A first set of fast-path nodes of the service is assigned to execute packet rewriting rules on packets received via the virtual network interface. Based on analysis of metrics obtained from the set of fast-path nodes, a determination is made that a criterion for scaling up fast-path nodes has been met. A second set of fast-path nodes is assigned to execute packet rewriting rules on additional packets received via the interface, with the number of nodes included in the second set based on a statistic (indicated by the metrics) of the size of packets transmitted via the virtual network interface.

  • Distributed evaluation of networking security rules
    Patent number: 12244648
    Abstract: A plurality of security rule processing nodes is configured for network traffic of a set of sources and destinations. Respective subsets of configuration information of the sources and destinations, including security rules, are transmitted to the nodes. Respective addresses of at least a subset of the nodes are transmitted to a packet processing intermediary. The intermediary requests evaluation of applicable security rules with respect to packet flows by selected nodes prior to initiating routing actions for packets of the flows.
