COMMUNICATION SYSTEM, CONTROL APPARATUS, COMMUNICATION METHOD, AND PROGRAM

摘要

A control apparatus is connected to the network and includes: a switch control unit controlling the second switch; a path examination unit determining whether communication from an arbitrary source connected to the network uses a plurality of paths; and an erroneous learning prevention processing unit executing, when a merging point of the plurality of paths is the first switch, a predetermined erroneous learning prevention process. Occurrence of a loop or route flapping is prevented in a network environment including both a switch having an address learning function and a switch without such function.
