requirements hardware software vendors publish caida web pages appendix questions earlier draft caida wg charters types network transport layer metrics used isps engineering operating networks customers verifying service guarantees b new services likely offered e g diffserv need higher layer metrics better monitor manage services c new differentiated transport application layer services

flow points measurement specific users isp customer etc requirements h metrics relate network behavior perceived users correlate performance appendix b background ietf working groups rtfm wg realtime
