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
