Raj Bhattacharjea is a full time developer of ns-3 in the employ of the Georgia Institute of Technology.

tcp-star-server example added
tcp-errors example checked in. Subsequently removed.
Cleaned up some TCP doxygen.
Evensky test case added as a regression test and announced to list. Subsequently removed.
Make PacketSink multitasking for TCP (closed bug 244)
Fix TcpSocketImpl rx buffer logic (closed bug 248)

Fix TCP closedown FINs (closed bug 242)
Actually implemented TCP finite rx buffer (closed 239)
Extensively tested ns-3 in prep for the 3.2 release
- filed bug 323 waf --valgrind doesn't check for valgrind first
- filed bug 337 opt build fails in address.cc on Ubuntu 8.10
- filed bug 343 utils/bench-packets is broken and asserts
- filed bug 349 packet unit test fails on optimized build
- filed bug 358 calling listen on non-closed TCP sockets sends resets, sh...
- filed bug 359 *SocketImpl::Bind returns something other than -1
Helped Mathieu debug GTNetS TCP port for ns-3-simu use for his demo. End result was deciding that nsc is more mature at this point, but working through the issues identified some bugs, and got me a working simu setup to use for testing purposes.

Identify fixes to be included in ns-3.2.1
- Build environment issues
  - waf/python-scan Bug 370
- Bug 371
Circulate said fixes for consideration
Decide a date for release
Learn more about release process (tarballs, release tagging, etc.)

Debugged the code mailhook, there is one issue
- The mailhook script is running as whoever pushes the commit, not as user code (i.e. when I push, the script runs as user raj, and the mail command sends a mail from raj@nsnam.ece.gatech.edu; how do I ensure that the mailhook script runs as user code every time?
  - Mathieu and Tom suggest the fix is to use the exim conf to do an address substitution.
error with hg-ssh file is preventing check ins to the new ns-3-dev
Web migration requires some small downtime to reset sql passwords
dump/backup the sql databases, migrate and import them on the new server
verify that all of the doxygen/html/texinfo etc scripts will run on the new machine
- see email name "nsnam updates and status" sent Sept 12 to Tom and George

Basics of ns3 overall model
- Nodes
- Protocol stacks
- NetDevices
- Channels
- Packets
Interesting Implementation Details
- Aggregation/GetObject
- Role of callbacks
Primer on tracing
Primer on attributes system
- Show the gtkconfigstore
Possible ports of some more GTNetS stuff (Jeffay example, http browsers and servers)
- http port(s) might not be necessary with simu being able to do microhttpd
Explain the statistics framework
Show some potential visualization (nam, Gustavo's python stuff?)

Cleanup TcpSocketImpl::Recv code (its ugly and inefficient)
Address bug 250
Use ns-3-simu to debug TCP
- process microhttpd<->simulator "native" TCP<->tap net device<->real linux<->real firefox
- replacing simulator "native" TCP from above with NSC works, but above setup doesn't, indicating bugs
Help Michelle with random variable API changes
