4. Mininet
Project website: http://mininet.org/
Emulator for real-world networks which uses real kernel, switch, and
application code on just a single machine
Internally uses Linux containers to emulate hosts, switches, and links

5. Virtual Hosts
For each virtual host, Mininet creates a container connected to a
network namespace

6. Virtual Hosts
For each virtual host, Mininet creates a container connected to a
network namespace
Each network namespace consists of a virtual network interface and
associated data, such as ARP cache and routing tables

7. Virtual Hosts
For each virtual host, Mininet creates a container connected to a
network namespace
Each network namespace consists of a virtual network interface and
associated data, such as ARP cache and routing tables
Virtual interfaces are connected to software switches via virtual
Ethernet (veth) links

8. Interface
Both a command line interface as well as Python bindings

9. Interface
Both a command line interface as well as Python bindings
Running the CLI: sudo mn

10. Interface
Both a command line interface as well as Python bindings
Running the CLI: sudo mn
By default creates a toy topology
