Please put the following quote from the link on the CSCI361 course page entitled "The LAN turns 30, but will it reach 40?" in context: Metcalfe said. "We wanted everything to be passive and simple" he explained. "The token-passing people -- and that included IBM Token Ring -- said they were deterministic, since you knew the token would be passed around in a certain amount of time. But if you counted the processes that had to be undertaken if the token was lost, it was a lie. I know that sounds nasty, but for 10 years I had to put up with that crap from the IBM Token Ring people -- you bet I'm bitter."
