That’s not the only reason Token Ring lost out. Token-passing yields deterministic access to the wire whereas CSMA/CD granted burst access on-demand. We observed at Wall Street Banks the implications of this difference in terms of the latency involved in delivering market data to traders. The bank using Token Ring had to segment their networks into smaller pools of stations using routers to decrease that latency.
