This Week

Monday I made my proposal. No not that kind. Stuff happened on Tuesday and Wednesday... Thursday I read and today I read some more. So here's what I read.

Frame Relay is a type of WAN connection based on packet switching. Packet switching basically means sending packets through different paths. It operates on virtual circuits where each client has their own allocated bandwidth. When you send data you have the CIR and the Access Rate. The CIR determines how much data is sent before it might be dropped and the Access Rate well... it's the Access Rate aka bandwidth. Back to virtual circuits they're just like a physical on except virtual so your data is moving across a large infrastructure that it never sees because it looks like it's own circuit. There are two types of virtual circuits. Permanent and switched which is like a leased phone line. The permanent is always in place while the switched is like when you make a phone call the connection is established and then dropped when the call or connection is through.

That's just one of the WAN types I read about but I'd rather not regurgitate everything I just read.

Gonna try and fix my dad's grandfather clock this weekend. I MUST HEAR THAT WESTMINSTER CHIME!
You gotta skip to the 28 second mark...
