Brandon Heller 433a7cc88c Make Ripcord-specific topologies optional 
If ripcord.dctopo imports properly, then include its topologies in the
list of available ones.  Also replace topo.py with new generic
topologies and update paths.

Brandon Heller 8b5062a3a1 Move TreeNet to new Mininet API 
Also remove all non-object-oriented legacy Mininet code and update
tests.

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

Brandon Heller 89bf31030b Move Node functions into their own file 
Nodes include Switch, Host, and Controller; move these to a separate
file.

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.

Brandon Heller 220890a0c9 Move utility functions out of mininet.py 
Having a file with the same name as its package creates hard-to-diagnose
import error, so rename mininet.py to net.py.  This commit moves utility
functions, generally those dealing with network namespaces and interface
management, into their own file.

Also fix a few minor formatting bugs and clean up logging code (which
had issues when multiple files would import mininet.logging_mod).
 2009-12-20 09:32:43 -08:00
Brandon Heller bc547080b8 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
topology object along with controller, switch, and host classes.

The modified code is all in ripcordtest.py, but will need to replace the
main mininet.py code eventually.

Kernel-space support only, for now.

Bob Lantz b7640209a8 Changed to use class vars and method to track nodes. 
Useful for monitoring the output of a set of nodes.
 2009-12-17 16:30:40 -08:00
Bob Lantz 1417fe7283 Changed cleanup to do fast things first. 2009-12-17 16:29:55 -08:00
Bob Lantz 7df36e476e Changed linearbandwidth.py to be much (!) smarter - it now *reuses* the network! Amazing. 2009-12-15 22:40:12 -08:00
Bob Lantz f939eb5625 Changes to mininet.py: 
- invoke ofdatapath with --fail=closed (no controller = no connectivity!)
- stop hosts before switches before the controller
	- this seems slightly more sensible
	- it's the reverse of the startup order
- fix retry() so it kind of works (it's actually helpful I think!)

Bob Lantz 05cce994c3 Haha, retry is definitely not right. Time to take a break I think. 2009-12-15 19:59:48 -08:00
Bob Lantz 0a9ea29fd2 Fixed problem for empty lists in cleanup. 
Added retry() function for createLink to see if it helps (probably won't.)
Random edits to docs.
 2009-12-15 19:53:22 -08:00
Bob Lantz 696a619d0e Minor tweaks and corrections. 
Added commentary on control network to mininet.py.
Hopefully fixed linearbandwidth.py for real.
