> Probably a good thing it was dropped along the way or I can only imagine what Comcast would have done with that. You think you're joking. ToS morphed into DSCP [1], which is sometimes used in residential networks to prioritize VoIP. (I can't speak to business or industrial networks; presumably it finds use there as well.) WLAN networks can be configured to heed this priority, more aggressively grabbing airtime for high-priority packets. I configure my home network that way. DSCP does not generally cross the home network<->Internet boundary, but there is one major exception I know of: Comcast. They tag all non-CATV traffic as the lowest priority (DSCP 8), resulting in terrible performance of any home network configured to heed DSCP values. (You can avoid this by stripping DSCP values from inbound packets.) [1] https://en.wikipedia.org/wiki/Differentiated_services https://en.wikipedia.org/wiki/Differentiated_services
