Abstract
A load balancing system may include a switch coupled with a plurality of servers and a controller. A flow table may include default flow entries with each default flow entry including a different match pattern. At least one of the default flow entries may include a match pattern with an unrestricted character so that the match pattern having the unrestricted character is satisfied by a plurality of data flow identifications. Each of the default flow entries may include an action to be performed for data packets having data flow identifications that satisfy its match pattern. A data packet including a data flow identification for a data flow may be received from a client device. A default flow entry having a match pattern that is satisfied by the data flow identification is identified, and the data packet is processed in accordance with the action for the identified default flow entry.
