ova Southeastern University IP Address: 137.52.76.29 SDN Controller Ability to parse inward bound packets (e.g., ARP, ICMP, TCP) and make packets to send out keen on the network NODEFLOW CONTROLLER Node is a fast, lightweight, and proficient server-side java script platform based on Google's V8 runtime. FLOWVISOR CONTROLLER Flow Visor is a new software-defined networking (SDN) controller SO as to enables network virtualization by in-between a physical network keen on several logical networks. Flow Visor ensures SO as to each controller touches simply the switches and possessions assigned to it. Flow Visor slices a physical network keen on abstracted units of bandwidth, topology, exchange and network machine central processing units (CPUs). It operates as a see-through proxy controller between the physical switches of an OpenFlow network and other OpenFlow controllers and enables several controllers to function the similar physical infrastructure; much similar to a server hypervisor allows several operating systems to use the same x86-based hardware. (Rouse, 2013) Purpose of FlowVisor Flow Visor is a particular purpose OpenFlow controller SO as to acts as a transparent proxy between OpenFlow switches and several OpenFlow controllers FlowVisor creates rich "slices" of network resources and delegates manage of each slice to a dissimilar controller Flow Visor enforces separation between each slice, i.e., one slice cannot control another's interchange. (Flowvisor, 2014) ROUTEFLOW CONTROLLER RouteFlow is an unlock source project to give virtualized IP routing services in excess of OpenFlow enabled hardware. OpenFlow controllers such as POX and Ryu, which are used to attach the switches to the RFServer.
