apply ANS group patches.

Patches allow to use specific per-link delay distributions, and to assign deterministic IP address to TCIntf interfaces.
Patches also add a "deb" target to the Makefile in order to create the debian package.

Only use 80 hosts for linearbandwidth.py for now

In the long run, we should debug the performance issues
with kvm and Ubuntu 15. For now, however, we're relaxing
the constraints.

Closes #594

Tolerate slow startup/lost pings for now

In the long run we should troubleshoot the performance issue
on kvm/Ubuntu15, but for now we are relaxing the constraint.

Closes #593

Use ifconfig for interface verification.

Previously we were using both ip link and ifconfig - not only is
this inconsistent and redundant, but it also broke when newer
ip link changed the reported names of certain interfacs to
"h1-eth0@36:".

Fixes #592

vm_clean: delete keys from from /etc/ssh/ before shipping vm

It's a bad idea for all Mininet VMs to share the same SSH keys.
Certainly users can regenerate their own keys, but it's better
if we don't ship a key and simply regenerate it on boot.

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!
