摘要
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.
