Topologies in mininet

The default topology in mininet consists of two hosts and two switches. There are many other topologies available in mininet, such as

  • single 

single creates a topology with a single switch attached to the number of hosts that are mentioned by the user
sudo mn --topo single,[no_of_hosts]
Fig 1. [ sudo mn --topo single,2 ]

  • reversed 

reversed creates a topology similar to the single command but the interfaces are assigned in a reverse order
sudo mn --topo reversed,[no_of_hosts]
Fig 2. [ sudo mn --topo reversed,2 ]

  • linear 

The linear keyword creates a linear topology with the specified number of switches and hosts
sudo mn --topo linear,[no_of_switches],[no_of_hosts_for_each_switch]
Fig 3. [ sudo mn --topo linear,3,2 ]

  • tree 

The tree keyword creates a tree topology of the specified depth of switches. We can also specify the number of children
sudo mn --topo tree,[depth],[no_of_children]
Fig 4. [ sudo mn --topo tree,3,2 ]

  • torus 

A torus topology can be created using the torus keyword
sudo mn --topo torus,[length],[breadth]
Fig 5. [ sudo mn --topo torus,3,3 ]
These were the inbuilt topologies in mininet.

GOOD LUCK!

CUSTOM TOPOLOGY IN MININET

CREATE CUSTOM TOPOLOGY IN MININET To create a custom topology in the mininet environment, we are going to use a python code. It is very simple, no need to acquire deep knowledge of python programming language especially for this task. 1. Import necessary packages *Topo from mininet.topo import Topo subpackage topo is being imported from the package mininet. 2. Create a class object class MYTOPO ( Topo ) : (Don't forget to have a similar class name and filename) 3. Create init method init method in python has similar functions as constructors in java. def __init__( self ):    Topo.__init__( self ) 4. Add Hosts Hostname=self.addHost ( "hostname" ) 5. Add switches switch_name=self.addSwitch ( "switch name" ) 6. Add links self.addLink ( "node name 1", "node name 2" ) 7. Name your topology Finally, we name the topo to call it in the command line. topos = { 'cust': ( lambda: MYT...

dpctl in mininet

dpctl command in mininet The dpctl program is a command-line tool for monitoring OpenFlow switches. It can show the flows, features, configuration, table entries, etc. of the switches. It can work with any OpenFlow switches. dpctl is a switch management utility. dpctl show Shows the basic information of the switch, its flow table, ports. 2. dpctl dump-desc [switch] Prints switch description 3. dpctl dump-ports [switch] Prints port statistics of the network devices attached to the switch 4. dpctl dump-ports-desc [switch] Gives detailed statistics of the network devices attached to the switch 5. dpctl dump-flows [switch] Print all flow entries in the associated switch dpctl dump-flows [switch] [flow] Print all the matched flows in the associated switch Flows and flow table: Before data transfer Stimulating TCP data transfer Observing TCP flows in switches Stimulating ICMP flows using pingall and observing...
