From different perspectives, each of these notions of end-to-end has meaning. Would you want to consider one or the other or both in the
Randy, There is a cluster of closely-related variants on the issue you raise: [] to what extent does a given exchange point (NAP/MAE/etc) constrain the performance that a user sees (in what a user thinks of as end- to-end). For example, an FTP could flow at 800 kb/s for a given pair of users, except that MAE-north is congested, so the FTP can only flow at 400 kb/s. [] to what extent does a given exchange point constrain the performance that a provider sees (in what a provider thinks of as end-to-end). For example, a given pair of backbones could sustain 20 Mb/s over a private interconnect with acceptable packet loss, but can only sustain 10 Mb/s over the Altoona NAP. panel? -- Guy At 01:11 PM 8/30/96 PDT, Randy Bush wrote:
Analysis of Actual End to End Performance accross the NAPs/MAEs An excellent topic, to be sure, but how do you propose that this be measured?
And there's a subject for a NANOG panel in itself.
I can think of some interesting experiments that would involve cooperation of multiple peers. But there are folk far better based in measurment than I who might suggest some fun stuff. Guy, Steve, ..., this is your cue.
