The title above may seem a little odd given Ethernet’s long and healthy life. Keeping conversation to more recent Ethernet standards (10/100/1000/10000/40000/100000 Mbps) the transmission technology and encoding standards have come a very long way for Ethernet. I remember when 100Mbps ports were the absolute norm and when 1Gbps ports were spared for very special (high paying) customers often on a single line card on a router!!! A router!!!
David has a great overview of the NBASE-T Alliance and their plans for 2.5 and 5 Gig Ethernet. Read on for his take and some links to great reading material!
