SCTP and OpenBSM in FreeBSD

Here are two quick notes on my favorite operating system. First, support for Stream Control Transmission Protocol (SCTP) has been added to FreeBSD CURRENT (i.e., 7.x). SCTP is a layer 4 alternative to TCP or UDP. I saw it mentioned in the final issue of Cisco's Packet magazine, in the context of NetFlow , specifically the new Flexible Netflow. When I get a chance to test this it will probably be using this technology.

Second, Federico Biancuzzi conducted an excellent interview with Robert Watson regarding OpenBSM and FreeBSD. This is incorporated into the upcoming FreeBSD 6.2, which I expect to see in early December.

I'm wondering whether New Cisco Netflow is still unidirectional or they will change.

I have been playing with Solaris/Ulticom SIGTRAN stacks for about 3 years and SCTP is used at layer 4. Nice to see I could at least use SCTP at home for fun and….something…Thanks for the info.

Better late than broken? At the risk of sounding critical to this commentor, OS delivery delays are a sign of a working QA process, not a broken development process. It's entirely clear that the software development industry has no idea how to "schedule" software development, and a slip of a few weeks is essentially optimal by contemporary development practice standards. I'd much rather have a two or three week delay in delivering software than delivering it known-broken, which *is* the industry practice.
