Remove/merge obsolete examples

Move TreeNet to new Mininet API

Also remove all non-object-oriented legacy Mininet code and update

User-space compatibility is untested, but most of the code for it is
still in.

89bf3103 12/20/2009 10:19 PM Brandon Heller

Move Node functions into their own file

Nodes include Switch, Host, and Controller; move these to a separate

This file still could use some attention to hide private functions.
Node seems like a primary class to extend, for adding stuff like Open
vSwitch, so it could benefit from a simpler interface.

220890a0 12/20/2009 05:32 PM Brandon Heller

Move utility functions out of

Having a file with the same name as its package creates hard-to-diagnose
import error, so rename to This commit moves utility
functions, generally those dealing with network namespaces and interface...

bc547080 12/20/2009 12:03 PM Brandon Heller

Rewrite Ripcord test and most of mininet

Make much of the Mininet code object-oriented around the new Mininet
object, and create a generic way to build a Mininet.

Previously, each network topology was created by Mininet API calls,
which seems much less approachable for new users than passing in a...

51270ce4 12/18/2009 08:12 PM Brandon Heller

Use setuptools to install python files

Now, to reference mininet files, use 'import mininet.mininet'.

PYTHONPATH mods are no longer required for installation.

40580731 12/18/2009 12:31 AM Bob Lantz

Added simple all-to-all UDP bandwidth test.

Changed to be much (!) smarter - it now reuses the network! Amazing.

696a619d 12/16/2009 02:50 AM Bob Lantz

Minor tweaks and corrections.
Added commentary on control network to
Hopefully fixed for real.

65733319 12/16/2009 01:22 AM Bob Lantz

Fixed to import Cli, so it should work now.

9dbb68df 12/15/2009 06:37 AM Bob Lantz

Fixed iperf test.
Not sure if I want nox_core -v in - it's useful for debugging. (and still depend on routing, which I haven't been
able to test yet.

77131e8f 12/15/2009 06:13 AM Bob Lantz

OK, now we run 'routing' for the nox configurations with loops.

Unfortunately, I can't test this at the moment since nox seems not to
be able to find the routing module.

Added/renamed examples:,

Added -v flag to nox arguments, so we have some chance of figuring...

c53fa3ba 12/15/2009 05:35 AM Bob Lantz

Second crack at a that actually works. was a name conflict - ugh!
This one creates a network successfully, but ping doesn't work with
nox out of the box at least.

0b084dd5 12/15/2009 05:01 AM Bob Lantz

Added, which attempts to make a FatTree using ripcord and
instantiate a mininet Network based on its topology.

Also minor cleanup of and GridNet class in

2f534913 12/15/2009 04:14 AM Bob Lantz

First crack at allowing Controller to be customized.
Network may now be used with custom controllers.
An example of doing this is in, which instantiates at TreeNet
using a custom Controller, NoxController, that runs nox_core rather
than the reference controller.

98332cb6 12/14/2009 09:22 PM Bob Lantz

Tweaks to documentation files and sshd and xterms examples.

Added scratchnetuser.

433503cf 12/14/2009 08:43 PM Bob Lantz

Added "from scratch" examples, to show how to create a network using
low-level primitives.

The "" example attempts to use nox as a controller rather than

More edits for INSTALL and README, and refinements for sshd and xterm

55dd9368 12/11/2009 05:21 PM Bob Lantz

Cleanup of doc files.
Fixed (and cleanup) to clean up screen sessions.
Cleaned up (though interface is still in flux.)
Added 1024-node network example (
Added example showing multiple tests on a single network (

08cef003 12/11/2009 02:17 PM Bob Lantz

Changed cleanup to vaporize zombie screen sessions.
Other minor cleanup.

Batteries still not included (for the moment.) ;-)

3da2b148 12/11/2009 11:33 AM Bob Lantz

Place 'root namespace' in xterm title to make it clearer that
the node is running in the root namespace.

af8f0b61 12/11/2009 11:22 AM Bob Lantz

Added INSTALL file incorporating Brandon's suggestions.

More tweaks for examples, which are still in progress.

42ba5d92 12/11/2009 10:34 AM Bob Lantz

Added sshd example, which starts up sshd on each host, allowing host access via ssh.

(It also adds a route from the root namespace to the data network via
the first OpenFlow switch, so when you ssh in you go through OpenFlow!)

Modified Network() to optionally decouple starting the network, running...

748e35d5 12/11/2009 07:39 AM Bob Lantz

Working on examples.
Added new example to create xterms.
Other minor changes.

4ccc7ee9 12/10/2009 09:47 AM Bob Lantz

Added examples, which may or may not work yet.
