METHOD AND SYSTEM FOR IMPLEMENTING LOGICAL PORT CLASSIFICATIONS

摘要

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.

1. A method for generating a plurality of instructions for managing a plurality of managed forwarding elements that forward data in a network, the method comprising:
identifying a set of equivalence classes for a plurality of logical ports of a logical forwarding element; generating a first set of instructions for associating a plurality of physical ports of a set of physical forwarding elements with the equivalence classes of the logical ports; generating a second set of instructions of the plurality of instructions for forwarding packets between ports of a set of physical forwarding elements to implement the logical forwarding element based on the different equivalence classes; and propagating the plurality of instructions to a set of managed forwarding elements.
