Cluster edition prototype: remote nodes and links.
We add a new experimental feature to allow Mininet to run acrossa cluster of machines. This is currently implemented via a setmix-in classes that provide remote nodes that are implementedvia 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.
IVSSwitch: support batch shutdown
Not a single command like the OVS one, but it still greatly decreases theshutdown time.
This does assume that stop() is called after batchShutdown(), which is true inthe current mininet code.
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 processof closing controller connections on receiving SIGTERM, but often mininet wouldhave continued on and removed the control network interface from the container...
Use a single ovs-vsctl command for speed/atomicity
Fix default of in-band control for OVS.fixes #279
Add support for batch shutdown of OVS switches.
This saves about 10 seconds for a 200 switch network.
Minor tweak of return value.
Check (and canonicalize) dpid arguments to Switch()

node: kill entire process group in terminate
mnexec already puts the shell into its own process group. Killing the entireprocess 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` methodsends the input to a shell which may be in another namespace (if --innamespaceis in use), while `Popen` would always run in the root namespace.
Style changes in mininet/node.py and removing used import in mininet/link.py
CPULimitedHost cleanup() calls superclass methodfixes #161
Clean up intfs in root NS, and avoid deleting HW intfs
It appears that under certain conditions, such as when anamespace exits, both ends of a veth pair may get dumpedinto the root namespace. We therefore now remove an interfaceboth from its home namespace and from the root namespace.
IVSSwitch: remove namespace warnings
IVS works fine using --innamespace.
IVSSwitch: use ovs-ofctl for dpctl functionality
IVSSwitch: add support for dpctl
dpctl is not included with IVS. The user will need to obtain it from theOpenFlow reference repository.
add support for the IVS virtual switch
IVS is an open source virtual switch available for download athttps://github.com/floodlight/ivs. It uses the openvswitchkernel 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 nowthis enables one or the other depending on the dpopts setting.
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 thinkabout it and also see if any one is using it...
