In case you've been wondering what the people that dwell in Layers 3 & 4 of the Internet have been up to lately, here's a taste:
Jon Postel's famous statement in RFC 1122 of "Be liberal in what you accept, and conservative in what you send" - is a principle that has long guided the design of Internet protocols and implementations of those protocols. The posture this statement advocates might promote interoperability in the short term, but that short-term advantage is outweighed by negative consequences that affect the long-term maintenance of a protocol and its ecosystem.
The full content of the draft is an interesting read, a window into what the future of base Internet protocols might look like in the future.
Just some light reading for your Friday morning 🙂
