None of those things could be implemented in the 1970 or 1980s at reasonable cost so they're not actually solutions at all.
Hell even making Ethernet fully switched didn't really happen until the 1990s thanks to Moore's law making the ASICs cheap enough.
Without mass adoption there's no reason to invest. Look at Token Ring, Ethernet's only real competitor at scale: it quickly started to lag behind. Ethernet shipped 100Mbps several years before Token Ring. The 1Gbps Token Ring standard was never put to hardware.
- Sporktacular 4y agoTDMA is an extension of TDM, which goes back to the 60's. Synchronization was already solved. Variable header size could be implemented with the same preamble concept already used by Ethernet, but used to indicate the end of the header. These were not hard problems. The technology existed, the affordability would have largely depended on adoption, so it's hard to say.
- xenadu02 4y agoWe'll have to agree to disagree. Obviously TDM was known but implementing it for ethernet at a reasonable cost was just not an option at the time (in my opinion).
