notes & ideas[edit]

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 '')
  • 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)
