Software Defined Networks (SDN) is the next wave in networking evolution. It may be considered as a revolution rather than an evolution since; many concepts of conventional network protocols are reshaped. OpenFlow protocol is the most widely deployed protocol in SDN. Emulation of OpenFlow based network projects facilitates the implementation of new ideas and driving the development of the protocol. In this paper, a summary of many software components related to OpenFlow is presented. Most of these software components were tested by the researchers in order to simplify the choice for other researchers considering the implementation of OpenFlow projects. These tests showed that there are differences in performance for the controllers that support OpenFlow 1.0 and OpenFlow 1.3. Furthermore, the tested controllers differs in the applications they support.

Abstract:Simple Network Management Protocol (SNMP) is a well established protocol in network management. In order to apply this protocol in smart home environment, a proxy agent should be used. This proxy agent converts sensor readings to an SNMP compatible form. In this work LabVIEW toolkits are used to play this role. First by acquiring the sensors' readings via multiple sub agents then sending them wirelessly to a single master agent through various approaches. The master agent completes the role of the proxy agent by storing these readings in a database file using LabVIEW database toolkits. This paper demonstrates a test bed representing this system is carried out and an SNMP software is used to monitor and control the sensors remotely. The results show that the proposed smart sending approach greatly reduced the amount of traffic needed.
