c265deed 09/05/2014 06:07 AM Bob Lantz

Cluster edition prototype: remote nodes and links.

We add a new experimental feature to allow Mininet to run across
a cluster of machines. This is currently implemented via a set
mix-in classes that provide remote nodes that are implemented
via a connection to a remote shell, and remote links which are...

net: allow batch shutdown of multiple types of switches

Each switch class will be called to shutdown its own instances.

93cd5583 05/22/2014 07:22 PM Rich Lane

IVSSwitch: support batch shutdown

Not a single command like the OVS one, but it still greatly decreases the
shutdown time.

This does assume that stop() is called after batchShutdown(), which is true in
the current mininet code.

5cb4a542 05/03/2014 08:21 PM Gregory Gee

Add ability for for OVS switch start connect to controllers using protocols other than TCP.

net.addController( 'c0', protocol='ssl' )

This now allows OVS to connect to a controller using SSL. The default of protocol is 'tcp'
as it currently is.

IVSSwitch: wait for ivs to terminate before tearing down node

This was a problem when running IVS in a container. IVS would begin the process
of closing controller connections on receiving SIGTERM, but often mininet would
have continued on and removed the control network interface from the container...

node: kill entire process group in terminate

mnexec already puts the shell into its own process group. Killing the entire
process group cleans up after any background processes the user left running.

IVSSwitch: support running IVS in a namespace

This change uses the `Node.cmd` method instead of `Popen`. The `cmd` method
sends the input to a shell which may be in another namespace (if --innamespace
is in use), while `Popen` would always run in the root namespace.

Clean up intfs in root NS, and avoid deleting HW intfs

It appears that under certain conditions, such as when a
namespace exits, both ends of a veth pair may get dumped
into the root namespace. We therefore now remove an interface
both from its home namespace and from the root namespace.

IVS works fine using --innamespace.

IVSSwitch: add support for dpctl

dpctl is not included with IVS. The user will need to obtain it from the
OpenFlow reference repository.

27da832d 06/27/2013 09:50 PM Rich Lane

add support for the IVS virtual switch

IVS is an open source virtual switch available for download at It uses the openvswitch
kernel module.

Workaround: add default dpopts='--no-slicing' to UserSwitch

This disables slicing by default but fixes bandwidth limits.
Eventually we want to enable both to work together, but for now
this enables one or the other depending on the dpopts setting.

804c4bbf 06/26/2013 01:14 PM Bob Lantz

Workaround: add dpopts to UserSwitch

Currently, slicing on the user switch breaks bandwidth limits.
We don't yet have a good way of using both of them at the same time.
I'm inclined to turn off slicing by default, but I have to think
about it and also see if any one is using it...
