Removing unnecessary braces in RemoteController

8df24304 09/23/2015 12:29 AM Brian O'Connor

Updating OpenFlow default port to 6653

- Pass 6653 to controllers that Mininet starts
- Try to connect first on 6653 for RemoteController, then fallback to 6633

fixes #545

Avoid expanding a string into a list of chars

Fix #520

6cb68f26 04/14/2015 12:30 AM Bob Lantz

Simply use class names as option help

The justification for this is that 1) the options are
already documented in the API documentation and 2) the
class names are fairly self-explanatory, so adding short
descriptions doesn't add much.

In the future, however, we could add a short description...

Implement Switch.stop(), which doesn't call terminate

When I changed the switch implementations to call super().stop(),
I neglected to include a Switch.stop() method which didn't call
terminate(). This broke switch s1 stop and s1.stop().

Fixes #497

Remove redundant processing for '/'

c2be20f0 03/18/2015 11:00 PM Bob Lantz

Rename node.RYU to node.Ryu

Perhaps it should be RyuController, but just Ryu for now.
RYU made no sense because it's not an acronym.

Fixes #475

3dd8c2cd 02/04/2015 06:30 PM Bob Lantz

A controller should delete its interfaces if necessary

This was causing to not clean up its interfaces, since
those interfaces were linked from the controller to the switch
rather than vice-versa!!

deleteIntfs already will only delete interfaces whose names match...

node shell: remove unnecessary -m and unset HISTFILE

Since we already disable job notification with +m, it doesn't
make sense to set it in the original invocation!

It's also annoying if all of the host commands end up overwriting
your regular bash_history!!

Turn off printPid by default to avoid mnexec fork/exec

a4e93368 01/29/2015 08:26 AM Bob Lantz

Set batch=False in OVSSwitch for low-level API

If you try to use the low-level API, you are probably
not going to call batchStartup()! So, we set batch=False
by default. This means that buildFromTopo() needs to set
it to True, so we add a bit of irritatingly complex machinery...

cluster: add batchStartup/Shutdown, cleanup

bdad3e8c 01/27/2015 02:01 AM Bob Lantz

Merge OVSBatch into OVSSwitch

Note that we are changing the interface of batchStartup/Shutdown
slightly so that the method can choose not to start some of the
switches. We might wish to refine this a bit...

574d634f 01/26/2015 10:06 PM Bob Lantz

Don't clean up links that may have been dumped into root NS.

This should rarely happen - in the usual case, either the
links will be shut down by Mininet.stop(), or the interfaces
will be deleted by node.stop( deleteIntfs=True ), or the
links or interfaces will be explicitly deleted or stopped...

Add OVSBatch class (experimental)

This implements batch startup for OVS switches.

ef59cd88 01/24/2015 12:39 AM Bob Lantz

Return correct success condition in cgroupDel

Without this, we end up retrying until we fail, instead
of returning immediately on success!

9db6cdc2 01/22/2015 11:22 AM Bob Lantz

Call delete() in link.stop() ; warn on exited node.cmd()

We should think a bit about the semantics that we want here.
The comments say "stop and clean up link" so perhaps that's
what we want. However, we could also imagine stop stopping
forwarding on the link (and possibly allowing restarts)....

a8cc243a 01/19/2015 06:59 AM Bob Lantz

Add stp param to OVS and connected() to OVSBridge

This allows --switch ovsbr,stp=True to work correctly

d4be9271 01/19/2015 12:09 AM Bob Lantz

Merge del-br into cmd, and add reconnectms param

With newer versions of OVS, this allows us to set up a switch
with a single OVS command (if reconnectms is zero.) If reconnectms
is specified, then it slows things down slightly (but not much.)

c1b48fb5 01/15/2015 10:43 AM Bob Lantz

Stub out RemoteOVSSwitch.batchShutdown()

Eventually we should implement true batch shutdown.
In the mean time, we just ignore it. Note there's no good
way that I know of for a subclass to remove a superclass
method, so we changed the protocol a bit to require a return...

c069542c 01/15/2015 10:07 AM Bob Lantz

Add OVSLink/--link ovs, which uses OVS patch links when possible

127f35a9 01/14/2015 10:18 PM Bob Lantz

Revert to using OVS default OpenFlow versions.

It makes sense to follow Open vSwitch's lead here.
OVS 2.3 enables OpenFlow 1.0 through 1.3 by default.
OVS 2.0 has incomplete support for 1.3, but you can enable
it with protocols=OpenFlow13

171e8151 01/14/2015 10:15 PM Bob Lantz

Set OVSSwitch default protocols to OpenFlow10,OpenFlow13

For OVS versions 1.9 or earlier, this setting is ignored.

Set default route in one cmd line to avoid dc'ing root NS

Usually you won't want to create a node in the root namespace,
and usually you won't want to use the Mininet API to set your
(real) default route, but if you do then you will probably want
to use a single command line to avoid disconnecting an SSH...

Wait for controller shutdown.

Unfortunately, this can slow things down a bit - perhaps
100-200 ms in the case of ovs-controller, but I am hoping that
it may help slightly with #399.
