griebling jim irvine perspective fire additional information get ravi forwarded ravi thuraisingham enron communications 02 23 00 10 51 nevil ipn caida org 02 22 00 12 16 pm members caida org cc nevil caida org bcc ravi thuraisingham enron communications subject caida metrics wg meeting 2 mar 00 hello caida members update caida working groups metrics caida org mailing list b wg charters meeting 2 mar 00 metrics caida oeg mailing list set single mailing list name discussions wg topics passive measurements etc start moderated list e member list post join sending email nevil caida org asking added metrics list following initial set members sue moon brett watson hans werner braun matt mathis ian graham tony mcgregor john cleary joerg micheel kevin thompson jambi gambar daniel mcrobb david moore sean mccreary rene hatem shankar rao cindy bickerstaff jeff sedayao steve feldman bill woodcock two questions caida members else would suggest invited join list ii list continue moderated changed open list b working group developments following caida members meeting 8 feb 00 attempted define exactly problem could consider getting ietf working group started summary existing ietf wgs interests metrics given appendix b seems unlikely could get new ietf wg started believe instead run single caida working group network metrics rather two proposed earlier draft charter appended focuses producing educational material network measurement developing new metrics two areas greatest interest amongst caida members wg co chairs sue moon sprintlabs brett watson mfn abovenet invited attend first wg meeting agenda follows agenda caida wg meeting thursday 2 mar 00 10 4 pm abovenet downtown sjc see details 1 review wg charter reasonable set draft removed added 2 work revised charter detail identify work required part determine willing work attempt determine delivery times 3 discussion new metrics first attempt making list metrics considered 4 anything else location abovenet located knight ridder building attached fairmont hotel complex address 50 w san fernando st san jose ca 95113 rsvp help us organising meeting please send email nevil caida org telling us many attend organisation cheers nevil nevil brownlee visiting researcher phone 619 822 0893 caida san diego caida network metrics working group draft charter tue 23 feb 00 goals 1 education faq measuring internet actually mean measure anyway measured active vs passive end end vs provider network application vs transport layer rating schemes provider net performance pages internet weather map keynote etc publish caida web pages maybe info rfc survey paper metrics internet measurement current measurement efforts surveyor ripe test traffic amp iperf keynote skitter current tools publish caida web pages 2 service metrics define new metrics taxonomy current metrics ippm rtfm itu summary metrics used current services gather information ideas new emerging services especially diffserv based ones make list new metrics either improve measurement existing services support new ones list metrics questions appendix goes organise experimental implementation testing tools new metrics make recommendations implementation define core set really useful metrics recommend caida implement service measurement toolkit publish new metric definitions ippm rtfm produce document measurement 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 need new metrics service metrics measured multi isp environment e customers verify measurements f requirements would service measurement introduce equipment vendors g relevant specific techniques e g 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 traffic flow measurement rtfm concerned passive measurements two way traffic flows specified terms end point attributes primary goal produce improved traffic flow measurement model considering least following needs wider range measurable quantities e g relating ipv 6 class service b simpler ways specify flows interest c better ways control access measured flow data strong focus data reduction capabilities e efficient hardware implementation ippm wg ip performance measurement ippm wg charter develop set standard metrics applied quality performance reliability internet data delivery services metrics designed performed network operators end users independent testing groups important metrics represent value judgement e define good bad rather provide unbiased quantitative measures performance rfcs framework ip performance metrics rfc 2330 metrics connectivity rfc 2678 one way delay rfc 2679 one way packet loss rfc 2680 round trip delay rfc 2681 ds bulk transfer capacity 2 x instantaneous packet delay variation one way loss patterns wgs rmonmib wg thinking application performance measurement clearly hard problem e g mean response time measurement done passive means measurements presented etc short rtfm provides good distributed measuring system traffic volumes ippm concentrated transport layer behaviour current best effort internet rmonmib beginning consider application layer measurement
