This is so interesting! Somehow I had never learned of the "random delay" that apparently is the basis of how Ethernet works.

- zokier 6y agoWell, the random delay thing is not really relevant in modern switched networks where each switch port is a separate collision domain. The whole core concept of Ethernet of a shared "ether" which messages are sent through has pretty much died because switched networks provide better performance and moores law made them economical
- mhalle 6y agoWhat about WiFi, and the adage, "you can't switch air"?
- zamadatix 6y ago802.11 handles it, the Ethernet frames just see things as being switched with a lot of buffering and random delay.
- tsomctl 6y agoCheck out CDMA. There's a blog owned by one of the original engineers at Qualcomm that goes into the history and theory of CDMA. Unfortunately I can't find it.
- p1mrx 6y agoWiFi travels through space, which happens to contain air for pragmatic reasons. Wouldn't SDMA qualify as "switching space"? https://en.wikipedia.org/wiki/Space-division_multiple_access https://en.wikipedia.org/wiki/Space-division_multiple_access
