Short Description
Mininet image for creating random scale-free topologies
Full Description

sdn_intelligence

Execute start.sh to deploy the scenario

Once in the mininet CLI,

Script execution:

py simulate.py

Once running, it will create a failure in the network every 5 seconds (it could be more, if the execution of the failure takes more than 5 secondss)
To end its execution, press ctrl+c

Configuration is determined by config and repo_subnets files. Config must have a [main] section with the following attributes:

  • Ip: ip address of the controller (you can check it using "docker inspect opendaylight")
  • Distribution: distribution of link bandwidth between hosts and network

    • equal: uniform distribution
    • badwifi, wifi, xdsl, fiber50, fiber300: gaussian distribution centered at 3, 10, 20, 50 or 300 Mbps
  • MainSwitches: number of switches in the core network

  • MainHosts: number of hosts directly connected to the core network
  • Datacenters: number of datacenters in the core network
    network. "No" otherwise.
  • MinutesRunning: amount of time (in minutes) you want each simulation running
  • Batch: number of simulations you want to execute
  • FailuresType: type of failures you want to simulate in your network

It also will have another section for each extra network.

config example:

[main]

Ip = 172.17.0.2

Distribution = equal

MainSwitches = 20

Datacenters = 2

MinutesRunning = 180

Batch = 3

FailuresType = 0,5

[extra1]

Number = 1

[extra2]

Number = 2

Those [extra1], [extra2] are networks attached to the main network, and are defined in repo_subnets,
wich has the following structure:

repo_subnets example:

[extran]

Switches = x

Hosts = y

Where x is the number of switches you want in that extra network, and y is the number of hosts.

The 'Number' field is the number of networks of that type that you want in your network.

Please remember to remove the containers (sudo docker-compose stop if you are running it in detached mode or ctrl+c if

you are running it in attached mode, and sudo docker-compose down) after using it.
