Network Discovery Protocols

Who wants to learn about network discovery protocols? You do! I’ve finally uploaded the slides I used for a quick presentation on Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP) for CS 690C last Tuesday. (And by that, I mean “finally linked to them from here”, since I ended up presenting from that very web-based copy.)

So if you want an overview of what network discovery does and what the differences between CDP and LLDP are, there you go. And if you don’t, here’s the answers anyway: (1) things on a network can find out what they’re connected to, and (2) politics.

Good News on HB 1266

According to NCSE (third item down), HB 1266, this year’s anti-evolution bill in Missouri, is effectively dead. Its supporters are claiming it’s just because the Elementary and Secondary Education Committee can only submit so many bills to the House per year, and they dropped HB 1266 to make room for others. No idea if that’s the only reason, or if the opposition from teacher and school organizations also played a role.

Whatever the reason, it’s good news for science education in Missouri. We’ll see what happens next year.
