A SDN-based Network Simulator with OpenFlow-enabled Switches
Overview
OpenFlow module is an optional add-on to EstiNet network simulator and emulator. In an SDN (Software-Defined Networking) network, OpenFlow, as a control protocol, is used between a controller and a switch. With this add-on module, a simulated OpenFlow-enabled Ethernet switch can support in-band control plane or out-of-band control plane through which it is controlled by a controller or multiple controllers. A commercial or open-source controller software can be used to control the simulated OpenFlow switches directly in a simulated SDN network. To comply with OpenFlow protocol, the simulated switch also supports the operations of flow table(s), group table and meter table.
Key Features and Benefits
Support OpenFlow-enabled Switches
Multiple simulated OpenFlow-enabled switches can be connected together to form an SDN network in the simulation environment. By developing SDN controller applications to use switch resource, the functionality and scalability of newly-invented SDN applications can be tested and evaluated under this environment.
Compatible with Real-world Controllers
A Linux-based SDN controller program can be directly run up on a simulated SDN network to control those simulated OpenFlow-enabled switches. If the given controller is not a Linux-based software, the emulation mode of EstiNet can support the interconnection between an emulated SDN network and the given controller. The simulated/emulated SDN network helps test the functionalities of SDN controller application and debug the design flaws and operation errors.
