ns-3 Network Simulator

Summary

Specfile is posted for review: https://bugzilla.redhat.com/show_bug.cgi?id=807821

Design packaging scheme for ns-3 network simulator and provide it in Fedora.

Pretty usable spec file (both C++ and Python simulations work) for ns-3 version 3.16 is available at that bug report along with required patches.

Still missing:

• visualizer (TODO, should be easy),
• click (TODO, should be a bit of work but not too hard),
• openflow (might consider it when/if Blake Hurd's changes go upstream, see below for details).

To use ns-3 when installed via RPMs, you must use pkgconfig, e.g.

$ g++ first.cc pkg-config --libs --cflags libns3.16-core-debug libns3.16-network-debug libns3.16-internet-debug libns3.16-point-to-point-debug libns3.16-applications-debug

• Percentage of completion: 60%

Detailed Description

"ns-3 is a discrete-event network simulator for Internet systems, targeted primarily for research and educational use. ns-3 is free software, licensed under the GNU GPLv2 license, and is publicly available for research, development, and use.

ns-3 is intended as an eventual replacement for the popular ns-2 simulator." (ns-3 home page)

For now, we package ns-3.16 with some extra patches which will eventually be upstreamed (hopefully, at least).

Benefit to Fedora

Fedora will be more attractive to researchers, teachers and students in field of computer networks since it will be much easier to install and use ns-3.

ns-2 is widely used in academia, and it's expected that ns-3 will follow that suit. There are already a couple of courses using ns-3. (Tom Henderson keynote at WNS3 2011 mentions three, but there are at least three more: CS641 at Indian Institute of Technology Bombay, S-38.2188 at Aalto University, CS640 at Brigham Young University)

Scope

This is an isolated change, that requires adding packages to Fedora. ns-3 has quite some dependancies, and most of them are already in Fedora (see below).

How To Test

Tests and scripts used for testing simulator itself are provided in ns-3 and can also be packaged.

No special hardware or software is required; testing is handled by ns-3's test.py script that builds tests and executes them.

User Experience

Researchers, teachers and students will be able to install ns-3 much easier.

Dependencies

Definitly needed:

• everything mentioned in Fedora installation at nsnam wiki

Not needed but will package since it's easy to do:

• PyGraphviz, should be similar to NetworkX in terms of packaging (TODO), https://bugzilla.redhat.com/show_bug.cgi?id=740687
• NSC, bundled in ns-3-allinone
• Click Modular Router (bug 709082)

Possibly useful in the future/would be cool to have:

• LXC, already in Fedora
• OpenFlow, Blake Hurd's modified OpenFlow that works with ns-3
• NetAnim 3.0
• NEPI/NETNS/NEF

Contingency Plan

Release without ns-3 included.

Documentation

• ns-3 Documenation
• ns-3 Wiki
• ns-3 Wiki: Installation

Release Notes

ns-3 is a discrete-event network simulator for Internet systems, targeted primarily for research and educational use. ns-3 is now included in Fedora. This makes it easier for researchers, teachers and students in field of computer networks to install it and use it.
