  • Generating flows using common match techniques
    Patent number: 9686185
    Abstract: Some embodiments provide a method for a forwarding element that forwards packets. The method receives a packet and performs a hash lookup operation on one or more hash tables to find a matching rule for a packet. The method consults a common match data set to generate a wildcard mask. The method generates a flow based on the matching rule and the wildcard mask. The flow is used to process other packets that match each bit which is un-wildcarded.
    Type: Grant

  • Tracking prefixes of values associated with different rules to generate flows
    Patent number: 9680738
    Abstract: Some embodiments provide a method for a forwarding element that forwards packets. The method receives a packet. The method consults a tree structure to generate a wildcard mask. The consulting includes traversing the tree structure by tracing a set of bits from the packet header and un-wildcarding the corresponding set of bits from the wildcard mask. The method identifies a matching rule for the packet. The method generates a flow based on the matching rule and the wildcard mask. The flow is used to process each other packet that matches each un-wildcarded bit of the flow.
