The document provides an overview of Software-Defined Networking (SDN), including the architecture, models, and implementations such as OpenDaylight and Mininet. It covers topics like scalability, cost, and security in SDN, as well as essential commands for using Mininet to emulate networks. Various resources and links to further information are included throughout.

11. SDN Model

12. 1. Open SDN controller and Openflow: Opendaylight, ONOS, NOX, POX,
Floodlight, RYU, CISCO Brocade, NEC, … other (The Real World: Google 2010)
2. By Overlayer : NSX (Nicira) use VxLAN, NVGRE | Nuage Networks
3. White Boxes : Pica8, Cumulus (Test Drive Cumulus), Facebook Switches (6 pack
Wedge). Linux on Switches.
4. SDN via API: Go from CLI to Programmatic interfaces networking devices: OVSDB,
Netconf (Not SNMP)
5. ASICs : CISCO ACI Oplex
6. Open stack vision
7. NFV : https://www.opnfv.org/ | Virtualisation of servers => Virtualisation of routers,
switches, FW => containers, services, ….

14. Mini-Net Overview

15. • Mininet is a network emulator, or perhaps more precisely a network emulation
orchestration system. It runs a collection of end-hosts, switches, routers, and links on
a single Linux kernel.(https://github.com/mininet/mininet/wiki/Introduction-to-Mininet)
• Mininet is a network emulator which creates a network of virtual hosts, switches,
controllers, and links. Mininet hosts run standard Linux network software,
• switches support OpenFlow for highly flexible custom routing and Software-Defined
Networking. (http://mininet.org/overview/)
Mini-Net Overview

16. • Sudo mn
• Help
• Nodes : available nodes
• Dump : show details of the topology
• Net : show network links
• Operations :
- h1 ping h2 (ICMP !)
- xterm h1 : opening the host
- ping all
- iperf : Testing TCP bandwith
- iperfudp :
- exit
- sudo mn –c
• Sudo mn –link tc,bw=10,delay=10ms
Mini-Net Basic Command
• Wireshark
sudo wireshark &
Of : of messages filtring
• Topologies :
Sudo mn –topo=single,4
Sudo mn –topo=linear,4
Sudo mn –topo=tree,2,2

17. Mini-Net and Python
• Topologies :
I. Mininet topo : Sudo mn –topo=single,4 | Sudo mn –topo=linear,4 |Sudo mn –topo=tree,2,2
II. Python
A. With mini-net command :Custom :
Cd/home/mininet/mininet/custom
More README => sudo mn –custom custom_example.py –topo mytopo
Ls : more topo-2sw-2host.py
Sudo mn –custum test.py –topo mytopo
B. Python without Mini-net : Cd mininet/examples
