ns-3 RELEASE NOTES This file contains ns-3 release notes (most recent releases first). 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)
