new feature reviews

Still aiming for ns-3.14

• RED queues, mailing list post -> merged to ns-3-dev and is being kept there for now so as to not disturb the repository, but requires some relicensing of original BSD-licensed source before we should release it. This is expected to be done by 13 April.
• LTE, buildings, and antenna models: several review requests are here
  • Antenna patch requires resolution of comments in the Rietveld issue tracker
  • LTE merge is blocked by resolution of this issue
  • Buildings merge is being refactored for 1) the separation of pathloss models, and 2) the re-use of position allocators for the buildings allocator
• Dynamic Source Routing (DSR) -> author is responding to some final comments
• TCP Echo Code review here
• netanim (added to download.py). Proposed patch here

Slipping past ns-3.14

• TCP Options (just the encoding of the options in the header)
• HTTP traffic generator -> reviewed, needs revisions
• DelayBox -> author responding to comments
• TDMA model -> sliding to ns-3.15?
• BRITE Integration -> sliding to ns-3.15?
• Poisson Pareto Burst Process -> sliding to ns-3.15?, author responding to comments
• CLWPR (Cross Layer, Weighted, Position-based, Routing) -> sliding to future
• CSMA module improvements -> sliding to future
• GPSR (Greedy Perimeter Stateless Routing) -> Posted for pre-review, presently missing test suite.
• Switched Ethernet Device
• Finishing ns-3-click-mac extensions -> Blocked by queue API resolution
• Antenna Model patch Author must rebase patch against Nicola's patch.
• Packet Tag List

NSOC/GSOC code merges (seem to be slipping out of ns-3.14 timeframe):

• Monitor mode support (Update from Bjorn)
• LTE RRC extension
• UAN Mobility Model merge (from previous GSOC)
  • blocked on resolving changes to WaypointMobilityModel API

• Random Variable Stream
  • need to generate code review and may slip to ns-3.15; plan is to not touch RandomVariable or any models for ns-3.14
