Rewrite tolerance to be saner (plus or minus 20%)

04897513 01/22/2016 09:33 PM Bob Lantz

Collect all server output in iperf()

This still isn't ideal - this was breaking UDP iperf, which
can take a bit of time to print its output after you control-c it.

5365831d 01/22/2016 01:07 AM Bob Lantz

Use 0% loss when testing examples/simpleperf.py

Also clarified the code in test_simpleperf.py.

Fixes #590

6a69c3c7 01/22/2016 12:59 AM Bob Lantz

Fix UDP iperf.

c0793cb5 01/21/2016 01:33 AM Bob Lantz

Add "run" alias for "use" and integrate build/test options

Keeping "use" for now even though it seems harder to remember
than "run". And the build/test options are probably much
clearer being inline in the help.

327af97c 01/21/2016 01:32 AM Bob Lantz

Try to fix iperf race condition

This is more complicated than it should be. We are also relying on
the fact that waitOutput should eat extra prompts most of the time.
Still not perfect - it's hard to get this exactly right, and we
should try to make it easier!...

b78b99b6 01/20/2016 09:33 PM Bob Lantz

monitor() should return on timeout; docstring changes

It appears that read() has been blocking for some time,
so for now it makes sense to change the documentation to
match the functionality!

It's not entirely clear if monitor() expects this functionality....

a1bff4b0 01/19/2016 09:24 PM Bob Lantz

Add python-pexpect to dependencies

It's used by tests and isn't large.
Fixes #587

0b673d7c 01/19/2016 09:23 PM Bob Lantz

Update Ryu dependencies.

Allow RemoteController to connect to correct port.

Mininet: Rapid Prototyping for Software Defined Networks

The best way to emulate almost any network on your laptop!

Mininet 2.2.1

What is Mininet?

Mininet emulates a complete network of hosts, links, and switches on a single machine. To create a sample two-host, one-switch network, just run:

sudo mn

Mininet is useful for interactive development, testing, and demos, especially those using OpenFlow and SDN. OpenFlow-based network controllers prototyped in Mininet can usually be transferred to hardware with minimal changes for full line-rate execution.

How does it work?

Mininet creates virtual networks using process-based virtualization and network namespaces - features that are available in recent Linux kernels. In Mininet, hosts are emulated as bash processes running in a network namespace, so any code that would normally run on a Linux server (like a web server or client program) should run just fine within a Mininet "Host". The Mininet "Host" will have its own private network interface and can only see its own processes. Switches in Mininet are software-based switches like Open vSwitch or the OpenFlow reference switch. Links are virtual ethernet pairs, which live in the Linux kernel and connect our emulated switches to emulated hosts (processes).

Features

Mininet includes:

  • A command-line launcher (mn) to instantiate networks.

  • A handy Python API for creating networks of varying sizes and topologies.

  • Examples (in the examples/ directory) to help you get started.

  • Full API documentation via Python help() docstrings, as well as the ability to generate PDF/HTML documentation with make doc.

  • Parametrized topologies (Topo subclasses) using the Mininet object. For example, a tree network may be created with the command:

    mn --topo tree,depth=2,fanout=3

  • A command-line interface (CLI class) which provides useful diagnostic commands (like iperf and ping), as well as the ability to run a command to a node. For example,

    mininet> h11 ifconfig -a

    tells host h11 to run the command ifconfig -a

  • A "cleanup" command to get rid of junk (interfaces, processes, files in /tmp, etc.) which might be left around by Mininet or Linux. Try this if things stop working!

    mn -c

New features in this release

This is primarily a performance improvement and bug fix release.

  • Batch startup has been implemented for Open vSwitch, improving startup performance.

  • OVS patch links have been implemented via OVSLink and --link ovs

    Warning! These links have serious limitations compared to virtual Ethernet pairs: they are not attached to real Linux interfaces so you cannot use tcpdump or wireshark with them; they also cannot be used in long chains - we don't recommend more than 64 OVSLinks, for example --linear,64. However, they can offer significantly better performance than veth pairs, for certain configurations.

  • You can now easily install Mininet on a Raspberry Pi ;-)

  • Additional information for this release and previous releases may be found in the release notes on docs.mininet.org

Installation

See INSTALL for installation instructions and details.

Documentation

In addition to the API documentation (make doc), much useful information, including a Mininet walkthrough and an introduction to the Python API, is available on the Mininet Web Site. There is also a wiki which you are encouraged to read and to contribute to, particularly the Frequently Asked Questions (FAQ.)

Support

Mininet is community-supported. We encourage you to join the Mininet mailing list, mininet-discuss at:

https://mailman.stanford.edu/mailman/listinfo/mininet-discuss

Join Us

Thanks again to all of the Mininet contributors!

Mininet is an open source project and is currently hosted at https://github.com/mininet. You are encouraged to download the code, examine it, modify it, and submit bug reports, bug fixes, feature requests, new features and other issues and pull requests. Thanks to everyone who has contributed code to the Mininet project (see CONTRIBUTORS for more info!) It is because of everyone's hard work that Mininet continues to grow and improve.

Enjoy Mininet

Best wishes, and we look forward to seeing what you can do with Mininet to change the networking world!
