Extreme emulation power for the most complex networks
Mininet Extreme introduces mount and PID namespaces to Mininet.
This makes it possible to execute applications in containers which require
independent configuration spaces, such as Quagga
or OpenVPN
. Built-in
configurations make adding a Quagga router to a network topology easy. In
addition, Mininet Extreme is capable of connecting to the Transit Portal
BGP multiplexing service to provide BGP connectivity to emulated routers.
Mininet Extreme enables emulation of complex network topologies, including networks which combine technologies such as SDN and BGP. Networks can exchange routes and traffic with the real internet by combining Mininet Extreme with Transit Portal.
Mininet Extreme adds:
-
Support for mount namespaces, PID namespaces, legacy switches & routers
-
Built-in support for the Transit Portal BGP multiplexer and Quagga router
-
New utilities to support topologies with configuration data
-
New examples (in the
examples/
directory) to help you get started.
-
Support for generic hosts to make use of PID and mount namespaces
-
Polishing of PID namespaces, enabling individual containers to have their own
init
and view only their processes throughps aux
& etc.
-
Errors about controllers or bridges
(mn-br#)
already existingIf Mininet is not closed properly, it may not cleanup the junk (interfaces, processes, files in /tmp, etc.) which might be left around by Mininet or Linux. Try this if things stop working!
sudo mn -c
-
mount
does not show the expected bindings!By default,
mount
references/etc/mtab
, which is shared and updated by all containers and the host physical machine. As a result, this file does not remain in sync with the actual state of the system. To view the mounts within a specific container, execute:cat /proc/PID/mounts
where
PID
references the bash shell or another process within the container in question. To view the current mounts of the host system, replacePID
with1

If you are running Ubuntu 12.04 LTS (or earlier) you may see an error when
openvswitch
is being installed, such as the following:
Setting up openvswitch-datapath-dkms (1.4.0-1ubuntu1.5) ...
...
Building module:
...
Error! Bad return status for module build on kernel: 3.8.0-29-generic (x86_64)
Consult /var/lib/dkms/openvswitch/1.4.0/build/make.log for more information.
To resolve, simply execute the following:
sudo apt-get remove --purge openvswitch-datapath-dkms
sudo apt-get install openvswitch-datapath-lts-raring-dkms
