Outside Winter Insulation 7-layer clothing model

After being ejected from the pub this evening we had a brief discussion about the correspondance between winter clothing and the ISO Open Systems Interconnection 7 layer model. This is entirely normal.

My coat is OK except it is a bit too large, so even if I bung up the neck with a woolly scarf, it isn't snug enough around the hips to keep the chilly wind out. So I had multiple layers on underneath. My Scottish friend was wearing a t-shirt and a leather jacket – and actually did up the jacket; I am not sure whether that was because of the cold or just for politeness.

So the ISO OSI 7 layer model is:

  1. physical
  2. link
  3. network
  4. transport
  5. presentation and session or
  6. maybe session and presentation
  7. application

The Internet model is:

  1. wires or glass or microwaves or avian carriers
  2. ethernet or wifi or mpls or vpn or mille feuille or
    how the fuck do we make IP work over this shit
  3. IP
  4. TCP and stuff
  5. dunno
  6. what
  7. useful things and pictures of cats

And, no, I wasn't actually wearing OSI depth of clothing; it was more like:

  1. skin
  2. t-shirt
  3. rugby shirt
  4. fleece
    You know, OK for outside "transport" most of the year.
  5. ...
  6. ...    Coat. It has layers but I don't care.
  7. ...

2. skin
3. thermals

5. jumper
6. fleece
7. water/wind proof

In our new hipster dockerised AWS world, the OSI model is

1: wires
2: ethernet frame
3: UDP packet
2: ethernet frame in VXLAN
3: UDP packet
2: ethernet frame in VXLAN
3: UDP packet
2: ethernet frame in VPN generated in flannel/weave etc.
3: IP packet
7: cat
