As has been observed many times on NANOG, one of the advantages that a
circuit-switched network like the PSTN has over a packet-switched network
like the Internet is that the PSTN has leisurely call setup times and
relatively infrequent routing table lookups. No long-distance carrier
processes even 100 million phone calls in a day networkwide; yet there
are many routers which process billions of packets daily *per interface*.
