Renamed ->

Still could be better though.... and we need more topology

95f6e7b7 03/05/2010 12:55 AM Bob Lantz now works for kernel switch.

47e26cce 03/05/2010 12:55 AM Bob Lantz

Fixed to be compatible with new setIP().

086ef80e 03/05/2010 12:53 AM Bob Lantz

Changed setIP to accept numeric prefix len. Added Node.deleteIntfs().

48a8d297 03/05/2010 12:52 AM Bob Lantz

Removed blank line.

ddfbfc73 03/05/2010 12:51 AM Bob Lantz

Added convenience mode to allow info( 'a', 1, 'b' )

Later we may wish to optimize this so that the arg lists are
not created if the logging level is too low.

dc630c54 03/03/2010 10:37 PM Bob Lantz

Restored scratchnet and scratchnetuser demos.

Also changed the str format for nodes to use str() rather
than repr() so we don't end up with extraneous quotes.

efc9a01c 03/03/2010 09:52 PM Bob Lantz

Moved link creation into Node.addIntf() and fixed util:CreateLink().

Also tweaked cmd/cmdPrint to make them more beautiful and functional,
and a few other minor changes, such as using a new idiom for verbose.

These changes support reinstating the examples.

04fa18dc 03/03/2010 09:51 PM Bob Lantz

Changed cmdPrint to cmd.

a681f9b6 03/03/2010 09:50 PM Bob Lantz

Added debug() convenience function.

Mininet: A Simple Virtual Testbed for OpenFlow aka How to Squeeze a 1024-node OpenFlow Network onto your Laptop (Extremely Experimental Development Version 0.1, December 2009) --- Mininet creates simple OpenFlow test networks by using process-based virtualization and network namespaces. Simulated hosts (as well as switches and controllers with the user datapath) are created as processes in separate network namespaces. This allows a complete OpenFlow network to be simulated on top of a single Linux kernel. Mininet provides a set of Python classes and functions which enable creation of OpenFlow networks of varying sizes and topologies. In order to run Mininet, you must have: * A Linux 2.6.26 or greater kernel compiled with network namespace support enabled. (debian-testing seems to have such a kernel, but it doesn't work for compiling nox, unfortunately.) * The OpenFlow reference implementation (either the user or kernel datapath may be used, and the tun or ofdatapath kernel modules must be loaded, respectively) * Python, bash, ping, iperf, etc. * Root privileges (required for network device access) * The netns program (included as netns.c), or an equivalent program of the same name, installed in an appropriate path location * installed in an appropriate Python path location Currently mininet includes: - A simple node infrastructure (Host, Switch, Controller classes) for creating virtual OpenFlow networks - A simple network infrastructure (class Network and its descendants TreeNet, GridNet and LinearNet) for creating scalable topologies and running experiments (e.g. TreeNet(2,3).run(pingTest) ) - Some simple tests which can be run using test ) - A simple command-line interface which may be invoked on a network using .run( Cli ). It provides useful diagnostic commands, as well as the ability to send a command to a node. For example, mininet> h11 ifconfig -a tells host h11 to run the command 'ifconfig -a' - A 'cleanup' script to get rid of junk (interfaces, processes, files in /tmp, etc.) which might be left around by mininet. Try this if things stop working! - Examples (in examples/ directory) to help you get started. Batteries are not included (yet!) However, some preliminary installation notes are included in the INSTALL file. Good luck! --- Bob Lantz
