Release status

New feature merges

Already merged:

• Spectrum Modeling
• OFDM
• Bring rate representation in line with IEEE standard
• Enhancements to ns-2 trace reader (issue 473)
• Underwater Acoustic Network
• Rocketfuel topology reader
• WiFi patches for bugs 871, 881, 853

Pending merge:

Wait for ns-3.10:

• API for TOS bytes (issue 897) may wait for netfilter support
• Class name rename Scalar->Dimensionless (issue 445)
• NetAnim trace hooks for wireless (patch in preparation)

Critical issues

These issues are candidates to become blocker issues.

• Doxygen incomplete (discussed on list already)
• peekData warnings (issues 846 and 912)
• AODV problems reported by Kevin Peters (also, issue 879)
• Wimax serialize (issue 905)

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
