ns-3 RELEASE NOTES
This file contains ns-3 release notes (most recent releases first).
Release 3.1 (2008/06/30 tentatively)
========================
First supported ns-3 release.
- TCP bugfixes and support for packet tags
- CSMA NetDevice cleanup and documentation
- internet-node renamed to internet-stack
- Socket::RecvFrom added; "flags" argument added to Send calls
- updated doxygen
- several bugs and open issues closed out
- revised tutorial
Note: Some API in class ns3::Ipv4 and ns3::Ipv4RoutingProtocol is
deprecated and may be removed and replaced in future releases.
Release 3.0.13 (2008/06/02)
========================
- point to point links generate ppp pcap traces
- point to point links support asymmetrical data rates.
- generate doxygen documentation for all attributes and trace sources
- add ConfigStore and GtkConfigStore to contrib module
- socket API now support tx and rx buffers: implemented for UDP and TCP
- ARP cache now supports per-entry pending queues
- lots of bugfixes and implementation and API cleanups
Warning: among API changes in this release, Application::Start and
Application::Stop now interprets the time argument as a relative
instead of absolute simulation time, to align with how Simulator::Schedule
behaves. Any code that calls these APIs in the middle of the simulation
will need to be adapted.
The API of Simulator::StopAt (time) has also changed. Now it is
called Simulator::Stop (time), and takes a relative time, instead of
absolute.
Release 3.0.12 (2008/04/07)
========================
- Add Attribute support to the TypeId metadata system and add
attribute support to all in-tree models
- Add a mid-level helper API to build simulation topologies
and perform simple ascii and pcap link-level tracing.
- Large amount of structural changes to accomodate the needs
of the upcoming python bindings
- new rate control algorithm (RRAA) and a jakes propagation model
in the 802.11 model (Federico Maguolo).
- regression test framework added
- TCP delayed acknowledgements and multitasking server
Release 3.0.11 (2008/02/15)
========================
- Initial port of GTNetS TCP implementation (initial version
that does not support multitasking or delayed acknowledgments yet,
but supports a reliable stream service)
- Changes to the ns-3 object model to create a TypeId-based
metadata system
- lots of bug fixes throughout the system
- tutorial updates
Release 3.0.10 (2008/01/15)
========================
- Add tutorial document content;
- Valgrind option for "waf" tool;
- Doxygen organization changes.
Release 3.0.9 (2007/12/15)
========================
- A 802.11 model ported from Yans. This model supports:
* a rather extensive PHY model
* log-distance and friis propagation model
* a simple set of rate control algorithms (ARF, Ideal,
AARF, constant-rate)
* adhoc and infrastructure mode (beacon+assoc)
- Use smart pointer for Packet in the APIs
- A new contrib directory with helper classes:
EventGarbageCollector, Gnuplot
- Tracing support for Applications
- many bugs fixed
Release 3.0.8 (2007/11/15)
========================
- A simple error model
- Source files for ns-3 tutorial
Release 3.0.7 (2007/10/15)
========================
- OLSR routing protocol
- A timer class
- Additional mobility models (random waypoint, random 2D walk)
- A mobility visualization tool
Release 3.0.6 (2007/09/15)
========================
- Static multicast IPv4 routing
- Logging overhaul (NS_LOG macros)
- Refactoring of tracing subsystem
- Tutorial document started
Release 3.0.5 (2007/08/15)
========================
- Refactoring to support win32-based unix environments (Cygwin, mingw)
- "Packet socket" for allowing applications to access NetDevices directly
- Generalized, polymorphic Address class
- Add CSMA NetDevice model (from Emmanuelle Laprise)
- Modularize IPv4 routing support (from Gustavo Carneiro)
- Add mobility framework and basic mobility models
- Global unicast centralized routing
Release 3.0.4 (2007/07/15)
========================
- Enable waf as the default build system.
- Per-packet metadata: a system to track which headers and trailers
are added to a packet
- Simplifications to point-to-point devices and channel
Release 3.0.3 (2007/06/15)
========================
- Enable Waf for release tarballs: users can now build ns-3
with the "waf" tool. See doc/build-waf.txt.
- Add support for variable time precision: it is now possible
to run a simulation with an accuracy which is higher or lower
than a nanosecond: seconds, milliseconds, microseconds,
femtoseconds and picoseconds are supported.
- Optimize and rework the COM framework, solidify the component
manager
- Many small API cleanups
Release 3.0.2 (2007/05/18)
========================
- Implement a new memory management infrastructure based
on reference counting and smart pointers (the latter being
optional)
- Implement a COM-like framework with support for QueryInterface
to provide object extensibility
- Add support for a BSD-style socket API for user applications
Release 3.0.1 (2007/03/31)
========================
- First public release; not yet pre-alpha.
- Simple UDP-based simulation script (examples/simple-p2p.cc)
