Expect (was: Software Defined Networks)

I (and another programmer, now at Amazon) migrated our automation from TCL/Expect to Python/pexpect. I've had to write code for those portions of Expect that didn't carry over into pexpect. I also had to build a framework that allowed me to do rule-based programming in the same flavor as

+1 for Accedian If you're looking for more of a homemade solution, I've used the perfSONAR software suite on some cheap-ish servers running CentOS for 10gig testing. It's highly configurable. I had it set up to do scheduled tests so we could see how the network behaved over time. The results

I believe this isn’t anything that the Hotel is doing… It’s NANOG giving members a two-week head start on the hotel block and not announcing it to non-members until the end of that two weeks so that members get first crack at rooms in the hotel block arranged for the conference. To the best of
