Features that may slip
The following features are in danger of slipping to ns-3.10 or later:
- VANET mobility model (no reviews)
- TCP Vegas (blocked by lack of progress on TCP congestion control architecture)
- Chord/DHT (authors are planning to revise code based on comments)
- app store and build system refactoring
- remove ./waf --regression
