Abstract
The network control system of some embodiments implements logical port classifications to implement different features of logical networks onto a physical network. The network control system of some embodiments modifies flow entries at forwarding elements of the physical network to implement the logical network. The network control system classifies logical source and destination ports into disjoint equivalence classes for logical network flows in a virtualized network, and encodes this information in the tunneled traffic carrying the logical flow. The network control system of some such embodiments provides logical port classifications to minimize the necessary flow entries at each forwarding element of the physical network.
