Quotes on designing network protocols:
"No combination of old segments ... can cause the protocol to fail and have a connection set up by accident..."
"Different network layers may return different kinds of feedback. The feedback may be explicit or implicit, and it may be precise or imprecise."
"Additive increase multiplicative decrease (AIMD)... with multiplicative decrease, the guy that has more loses more... until all parties have the same amount..."
