TCP analysis, research and debugging tools: SIFTR v1.2.1 released

[Lawrence Stewart]

Hi All,

I'm very pleased to announce the release of a significantly improved
version of our SIFTR (Statistical Information For TCP Research) tool
for FreeBSD. It can be obtained from [1], along with other papers,
patches and software useful for protocol analysis, debugging and
experimental research.

SIFTR is a loadable kernel module supporting FreeBSD 6.2+ that logs a
range of statistics on active TCP connections to a log file. It provides
the ability to make highly granular, event-driven measurements of TCP
connection state. More details are available in the readme and changelog
available at [1].

Work on SIFTR v1.2.0 and v1.2.1 has been sponsored by the FreeBSD
Foundation [2] as part of the "Enhancing the FreeBSD TCP Implementation"
project [3]. SIFTR development prior to v1.2.0 was supported in part by
a grant from the Cisco University Research Program Fund at Community
Foundation Silicon Valley.

SIFTR's functionality will be merged into the FreeBSD base system in one
of the next steps in this project, and will hopefully ship with FreeBSD 8.0.

Cheers,
Lawrence
