@fivetonsflax@tilde.zone @ricci@discuss.systems We gave some thought to this approach but found it gets very hard to explain something like ARP or selecting the next hop in IP forwarding if you have reduced every forwarding device to a switch. It really matters whether it has an awareness of IP once you get into the details. When we call something a switch, we have left a lot of its behavior unspecified. Note that both Venn diagrams agree that the overall class of devices is "switch" - it's just that we can't leave it at that for the whole book.

@fivetonsflax@tilde.zone @SystemsAppr@discuss.systems @ricci@discuss.systems I do feel for Dr #Perlman ; I gave my hardback copy of "Interconnections" to a close personal friend. I narrowly missed meeting her due to commitments during my scholarship. #TRILL got done but it sure done got #enshittified in the process. Just ask Ivan #Pepelnjak ; He knows where the bodies are buried.

@fivetonsflax@tilde.zone @SystemsAppr@discuss.systems @ricci@discuss.systems The #IEEE #802.1aq rollup spec definition of a Two-Port MAC Relay #TPMR is really quite insidious and bothersome to follow. I consider it a litmus test for how much an LLM will actually #HALLUCINATE when faced with a human-written specification. Calling everything a switch... Danger, Will Robinson, special cases abount. #OpenBSD notably has its own software stub driver to model this class of network element.
