However the switches supporting OpenFlow protocol are extremely expensive and difficult to get. In order to facilitate the obtainment of switches supporting OpenFlow protocol, in this paper we introduce a general broadband router-based design of OpenFlow switch. The design can construct such a switch fully supporting OpenFlow protocol by only using general broadband router commonly found in markets and the open-source Linu
