Mininet

Project website: http://mininet.org/

Emulator for real-world networks which uses real kernel, switch, andapplication code on just a single machine

Internally uses Linux containers to emulate hosts, switches, and links

Virtual Hosts

For each virtual host, Mininet creates a container connected to anetwork namespace

Each network namespace consists of a virtual network interface andassociated data, such as ARP cache and routing tables

Virtual interfaces are connected to software switches via virtualEthernet (veth) links

Interface

Both a command line interface as well as Python bindings

Running the CLI: sudo mn

By default creates a toy topology

Some CLI Interaction

Displaying the hosts: nodes

Displaying the links: net

Executing a command on a host/switch: name_of_host/switchcommand
