The reduction system of load and load reduction system

摘要

Abstract invention patent: "the reduction system of load and load reduction system". The present invention stabilizes a system of network of open flow through the reduction of sending queries to a computer on the entries of flow were not configured, thereby reducing a load on a controller.Specifically, the controller registers, in a flow table of a switch, the entries of flow that define the rules and actions required to control uniformly packages as flows.When a packet is received, if an input stream that corresponds to the packet received has not yet been recorded in the flow table, the switch sends a query to the controller about an entry corresponding to the packet flow received, stacks packet received, and controls The transfer of packets that have the same header information than those of the stacked package.By using the package stacked until an input flow corresponds to the packets received is registered.
