cece39e4 05/10/2012 11:32 PM Bob Lantz

Thanks to James Zeng for pointing this out!

cfd38113 05/10/2012 05:59 AM Bob Lantz

Fix errRun to not exit until all of stdout and stderr have been read.

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...

50cebe67 04/14/2012 12:42 AM Bob Lantz

Add pmonitor() to make it easy to monitor popen objects.

237a3c54 04/13/2012 10:50 PM Bob Lantz

Pass code check.

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.

350fdbfe 04/10/2012 12:02 AM Bob Lantz

Allow modules (node.py) to be 1500 lines. Maybe reduce this someday.

548580d8 04/09/2012 11:54 PM Bob Lantz

Allow lists of nodes to be passed to getNodeByName
....which should perhaps be renamed!!!

149a1f56 04/09/2012 03:49 AM Bob Lantz

Apparently errRun isn't as flexible as I thought...

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

Add static cpu (and memory) assignment.

a7648e78 04/09/2012 03:49 AM Bob Lantz

Added simpleperf.py to examples.

32f7847b 04/04/2012 12:50 AM Bob Lantz

TCLink: pass correct parameters to superclass.

26c61734 03/25/2012 10:41 PM Bob Lantz

Add cgroup and ethtool dependencies for mininet (w/hifi integration.)

e1246c37 03/25/2012 10:39 PM Bob Lantz

Simplify port specification.

For the moment, I've removed the ability to specify
a dict of options without using **. This is a slightly
unfortunate trade-off since it simplifies implementation
at the expense of making the API slightly less convenient
(if somewhat more consistent.)

2d924f8a 03/25/2012 10:38 PM Bob Lantz

Add Mininet object to locals as 'net'

00d9b780 03/24/2012 01:41 AM Bob Lantz

Pass code check.

8139695d 03/24/2012 01:37 AM Bob Lantz

Use 's%s' for bw speedup; change burst to fix tbf and htb performance.

Change to allow addLink() without specifying ports.

44af37bc 03/24/2012 01:18 AM Bob Lantz

Change default period to 100 ms, which seems to help cfs at least...
rt is still somewhat broken.

beb05a71 03/24/2012 01:17 AM Bob Lantz

Move dumpNetConnections to util() because it's useful!

74ea006d 03/24/2012 01:17 AM Bob Lantz

Increase the quota and cpu fraction to get max cfs performance.

335ba99b 03/23/2012 08:33 PM Bob Lantz

Add --switch ovsl for legacy OVS.

8dcefd5f 03/23/2012 08:33 PM Bob Lantz

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.

a5af91d0 03/23/2012 02:08 AM Bob Lantz

Have errFail report cmd and stderr as well as exit code.

4deb7354 03/22/2012 09:44 PM Bob Lantz

Save parameters for future reference (e.g. OVS/tc workaround.)

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

Workaround: reapply tc config after OVS destroys it.

59542784 03/22/2012 12:28 AM Bob Lantz

Make CPULimitedHost method sig friendlier, and make 'cfs' default sched.

41245f50 03/22/2012 12:27 AM Bob Lantz

Add getNodeByName for hifi compatibility.

b684ff78 03/20/2012 11:23 PM Bob Lantz

Fix convenience configuration methods.

ea7c3260 03/20/2012 10:50 PM Bob Lantz

Whitespace fixes.

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.

8bebd377 03/20/2012 10:45 PM Bob Lantz

Fix is_switch() to always succeed + whitespace edits.

e52d0ee1 03/20/2012 10:44 PM Bob Lantz

Add TCLink for simplified tc-limited link creation.

5a8bb489 03/20/2012 07:17 AM Bob Lantz

Attempt at revised/simplified topo class:

- keys are strings
- metadata is simply a dict
- buildFromTopo greatly simplified

318ae55e 03/20/2012 07:10 AM Bob Lantz

Allow sendCmd( [ cmd, arg1, ... ] )

bf9c6ab7 03/12/2012 07:29 AM Bob Lantz

Clarify comments and finally remove ControllerParams definition.

14c19260 03/12/2012 07:20 AM Bob Lantz

Use port 0 for control interface on switches.

d7e5dfc5 03/12/2012 07:20 AM Bob Lantz

Minor tweaks: specify port, new repr()

8856d284 03/12/2012 02:44 AM Bob Lantz

Fix CLI commands.

14ff3ad3 03/11/2012 04:44 AM Bob Lantz

Fix examples to work with new API (and vice-versa.)

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.

e3c074b8 03/09/2012 09:53 PM Bob Lantz

Remove deprecated ControllerParams (for now.)

9addfc13 03/09/2012 07:48 AM Bob Lantz

Add OVSController to complete out-of-box Ubuntu experience.

d27a3c52 03/09/2012 06:08 AM Bob Lantz

Allow various subsets of (delay, bw, loss) and clean up status output.

2db4268b 03/09/2012 06:07 AM Bob Lantz

Fix NOX controller so that mn --controller nox,pyswitch,... works.

0dbfd3a6 03/08/2012 09:48 PM Bob Lantz

Add CPULimitedHost to file comment.

a908fafa 03/08/2012 09:48 PM Bob Lantz

Change default to vanilla Intf. Also edit comments.

8688ca92 03/08/2012 09:40 PM Bob Lantz

Remove debugging message.

Reorganize CPULimitedHost and add cgroup cleanup.

bf5becc7 03/08/2012 09:38 PM Bob Lantz

216a4b7c 03/08/2012 08:05 AM Bob Lantz

Support for CFS bandwidth limiting.
Also trying to fix NOX cmdline opt, but broken at the moment.
