Simulation and Emulation - SDN

   In This Post we are going to interpret briefly some of simulator and emulator of SDN, first of all we are going to know about Mininet, that is the first system that provides a quick and easy way to prototype and evaluate SDN protocols and applications. One of the key properties of Mininet is its use of software-based OpenFlow switches in virtualized containers, providing the exact same semantics of hardware based OpenFlow Switches.

next one is Mininet-HiFi: this is an evolution of mininet that enhances the container-based virtualization with mechanisms to enforce performance isolation, resource provisioning, and accurate monitoring for performance fidelity.

 Mininet CE and SDN Cloud DC : these are extensions to mininet for enabling large-scale simulations. Mininet CE combines groups of mininet instances into one cluster of simulator instances to model global-scale networks. SDN Cloud DC enhances mininet and POX to emulate an SDN-Based Intra-DC network by implementing new software modules such as data center topology discovery and network traffic generation.
