METHOD FOR BYZANTINE FAULT TOLERANT IN DISTRIBUTED SOFTWARE DEFINED NETWORKS

摘要

Disclosed is a method for overcoming a Byzantine failure in a distributed software defined networks (SDN) environment. The method for overcoming the failure includes: receiving, by the programmable switch, a request message from a client; generating, by the programmable switch, a request message in which a header is inserted; and transmitting the request message in which the header is inserted to a plurality of controllers. , receiving, by the programmable switch, a response proposal from at least some of the plurality of controllers, and deriving, by the programmable switch, an agreement on the request message.
