I am interested in the terminology of the term "root bridge." Why was this word chosen instead of the word switch, which would have been more intuitive?

Spanning Tree Protocol was developed for bridges. Switches are bridges. The original bridges only had a very few interfaces, and bridging was handled in software. When bridges became high-density interface devices, then they started being called switches. It began as a marketing term. Now, the bridging (switching) is handled almost completely in hardware.

  • Thank you for the answer. I did not know this details. Do you happen to know a good source where I can read about the history of bridges and switches? Or the history of computer networking in general? – yoyo_fun Aug 29 '17 at 6:49
  • Unfortunately, resource recommendations are explicitly off-topic here. This is something you could discuss in Network Engineering Chat. – Ron Maupin Aug 29 '17 at 13:52
