A little lower down the stack, I always liked the Evil Bit in TCP, a standard which removes all need for firewalls heuristics by requiring malware or packets with evil intent to set the Evil Bit. The receiver can simply drop packets with the Evil Bit set, and thus be entirely safe forever from bad traffic.
At the physical interface layer where data meets real life, I especially enjoy IP over Avian Carrier; that link in particular is to the QoS definition which extends the original spec for carrying packets by carrier pigeon.
Someone tested the evil bit and found a selection of real-world networks that react to its presence
Fun read, thanks for the link!
With the advances on SDcards, IPoAC is getting better and better.
As the saying goes, "for bandwidth, nothing beats a truck full of ~~tapes~~ 1TB MicroSDs hurtling down the highway".
The Evil Bit sounds like the real Do Not Track header field
What's wild is that IPoAC was actually tested, and shown to have a higher throughput than the local ISP. Source
