Introduction to Networking session

[epylko]

Hi everyone,

After watching the number of questions and issues related to network communications between the RoboRIO, drivers station, AP, USB, development laptops, and more, I was thinking about putting together a presentation that is basically "Networking 101". It could cover things like:

- History of the internet
- Networking Architectures
- logical - ring/mesh/star
- physical - ethernet - thicknet/thinnet/twisted pair/wireless
- OSI model
- What is a bridge, router, wireless channel
- Understanding IP addressing and subnetting
- Understanding DHCP/DNS/mDNS
- FRC-specific typical problems and solutions like:
- why can't I ping roborio-<team number>-frc.local?
- I can connect to the radio but not the robot
- what IP addresses do I use?

That's my first attempt at an agenda and I'm more than happy to tweak it. I was also thinking about trying to fit it into a 50-minute timeframe to present it at a FRC Championship, but I don't have enough time to get it done for 2016. I also think 50 minutes would be about the right length - it's easy to turn your brain into mush with too much of this stuff at once. I just hope 50 minutes would be enough - I'm sure there would be questions.

I think this could help teams understand what's happening in their team environment, and people might end up with a little more knowledge about how networking works.

Any thoughts? What would you like to see in an Intro to Networking session?
