notes & ideas

the 7-layer burito (containing both onion and mashed potatoe)

Layer 1

• cables, codes and waves

Layer 2

• express delivery: a packet for you, sir/mam. (how to unfold a burito and check it's what your ordered from 'buritos-R-us.com')
• the broadcast domain: if you cry, mom comes over to give you milk and cookies
• a bike-ride through the neighbourhood (ARP: drive through the street & meet the neighbours)

first steps into Layer 3

• the hierarchy of things / netmask: powers of 10 (one-zero) / zoom-out and see it scale
• routing : take a bus-ticket to hop over to the big city
• ports : reading your sisters' post.

the tools :

• wireshark / tcpdump
• a little scapy if you want it more spicy
• cisco packettracer
• full metal gear (linux routers, cisco router, cisco switches, nortel switches, loads of cables)
