Morning chaps.

We've just been talking about the OSI layer model at work (yes we are THAT bored) and my boss has said that there is a protocol which sits between the seven layers and passes data back and forth, but he can't remember what it is called. He thinks it begins with a 'P'.

I've never heard of this before. Have you?
