Re: Ethernet has stood the test of time
The significant expense in data cable wiring is labor, not the cable itself. With many vendors building Ethernet cards, the price became very competitive. Ethernet cards were considerably less complicated to make than Token-Ring cards. That said, Dr. Olaf Solderblum, from Sweden, was busy asserting his patent claim for token-passing networks. He had once worked for IBM. His patent licensing fee paid by Token-Ring card manufacturers contributed to the higher pricing of Token-Ring cards. There were also far fewer Token-Ring card manufacturers than Ethernet card manufacturers. Curiously, Madge Networks in England refused to pay for a Token-Ring license, took Dr. Olaf Solderblum to court in England, and was upheld by the court in its refusal to pay for a license to make Token-Ring cards.
