I also think this will be a non-starter as well. Anything like this will need to be physically processed by the routers, detracting them away from their real job of shifting packets around. There may not be a major cost to ISPs in terms of bandwidth, but the cost to the ISP in terms of additional load on the CPU resources on those routers could be more significant. Core routers run NTP because of the obvious benefit of time synchronisation, but it's also a handy way of measuring the latency across different bits of your network :) Cheers, Dean _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
