Clean up (and fix) OVSSwitch fast reconnect

12758046 06/25/2013 07:51 PM Bob Lantz

Fix setDefaultRoute to work with passed parameters.

Merge pull request #150 from MurphyMc/ovs_fast_reconnect

node: Make OVS switches reconnect quickly

dd21df3c 06/18/2013 12:09 AM Bob Lantz

Don't flush ALL routes and enable OPTIONAL default route/gw

fixes #152 hopefully

node: Make OVS switches reconnect quickly

Ordinarily, OVS switches back off when they can't reach their controllers.
Under the type of scenarios where Mininet is used, I think this is
probably just inconvenient. This patch set controllers to attempt to
reconnect every second.

node: Allow OVSSwitch to run in userspace mode

This adds a datapath parameter to OVSSwitch which allows one to tell OVS to
run in userspace mode rather than kernel mode. From the commandline, this
is --switch=ovsk,datapath=user.

Note that this makes "ovsk" and the OVSKernelSwitch alias misnomers. Since...

e5754ae9 05/23/2013 08:31 PM Shaun Crampton

Fix method name mismatch for setDefaultRoute.

229f112f 04/29/2013 09:04 PM Bob Lantz

Change OVSSwitch.dpctl() to call ovs-ofctl

This should fix the problem of dump-flows not showing the OpenFlow
flow table flows and only showing cached kernel flow table flows.

fixes #136

e5a15ced 03/29/2013 01:14 AM Bob Lantz

Change popen() to detach from terminal/process group.
This may or may not be the right thing to do - an alternative
would be to ignore SIGINT, but that would make the popen()
job unkillable by normal means! So we'll try this and see
how well it works.
Fixes #124

Tag node bash processes and add attach script
Try invoking bash processes with -s mininet:host,
for easy identification of hosts. This enables
easy attachment using the util/m script.
closes #121

Fix Node.MAC to return intf.MAC rather than intf.IP
Fixes #89 ; Thanks to Nikhil S. Menon for the bug report

node: Use space, rather than comma, to separate controllers
for OVS

Otherwise, OVS thinks the second controller is a parameter of the first, and
only creates one controller entry as seen in 'ovs-vsctl show'.

Fix SSHD example by generalizing input intf args

A number of functions in node.py look like this:
return self.intf( intf ).<other stuff>

Previously, self.intf(...) in Node would expect a string name for an
interface and return None if an object was passed in instead of a...

pep8: Fix E127 continuation line over-indented

There are a bunch of these remaining, but I don't think the right course is
to 'fix' all of them to make pep8 happy, but instead to either change
the test in pep8 to consider that a continuation line may itself...

now.

fa24f22d 08/01/2012 12:23 AM Bob Lantz

Workaround for openvswitch_mod rename and pass code check.

ec969b7f 07/02/2012 03:31 AM Bob Lantz

Change default controller for mn to ovsc (ovs-controller.)

Also add check to see if another controller is running -
eventually we should really detect errors from starting the
controller!!

Fix RemoteController which was still using defaultIP rather than ip.

55cf19c4 04/25/2012 09:21 PM Bob Lantz

Improve error handling for defaultDpid()

I think it's worth considering how we want to specify dpids for
switches. One way would be to have Mininet (optionally) pick them
automatically. Another way, which I have currently implemented, is
to intuit them from the name, for example s1 -> 1. The latter is...

669e420c 04/13/2012 07:38 AM Bob Lantz

Add default value mems=0 for memory placement.

92b601ab 04/10/2012 12:12 AM Bob Lantz

Allow fail-mode to be set.
Probably we should have a generic mechanism to specify OVS options.

197b083f 04/09/2012 03:49 AM Bob Lantz

Add static cpu (and memory) assignment.

Fix OVS legacy switch.

28833d86 03/23/2012 02:08 AM Bob Lantz

Retry deleting cgroup for the moment because it seems flaky.

Ultimately we may wish to create a mininet/ cgroup and do a recursive
delete at the end.

d1b29d58 03/22/2012 09:43 PM Bob Lantz

Fix printing pid for background tasks.

1aec55d9 03/22/2012 05:39 AM Bob Lantz

Fix convenience configuration methods.

efc99154 03/20/2012 10:46 PM Bob Lantz

Add warning in defaultIntf() if host has no interfaces.

Possibly this should be in intf() instead, as intf() is assumed
to always succeed.

8e3699ec 03/09/2012 10:10 PM Bob Lantz

Move init() into Mininet() and remove calls (since called automatically.)
Note: we should probably rename it "setup()" to avoid confusion.

84a91a14 03/07/2012 07:52 AM Bob Lantz

a6bcad8f 03/02/2012 11:45 PM Bob Lantz

Intf and Link classes. Latter support bandwidth limits using tc.
