How would web browser get the TOS bits on the received UDP packets? I know how to do this for Linux by setting IP_RECVTOS and using recvmsg. I do not think it is possible on any other OS, except by running raw socket or packet capture on the interface. Am I missing something? What is the point of the statistics that cannot be computed? _____________ Roman Shpount On Fri, Jul 28, 2017 at 4:02 PM, Varun Singh <varun@callstats.io> wrote: > It's easy to verify or compare the send and received TOS bits by > correlating them. > On Fri, 28 Jul 2017 at 22.10, Roman Shpount <roman@telurix.com> wrote: > >> On Fri, Jul 28, 2017 at 2:51 PM, Cullen Jennings <fluffy@iii.ca> wrote: >> >>> Just as a stab in the dark on how to do this ... >>> >>> Perhaps a table that had many packet where received for each DSCP that >>> had been received in the last second.
