Re: Measuring PoP to PoP latency--tools to use?
### On Wed, 22 Aug 2001 17:38:25 -0700, k claffy <firstname.lastname@example.org> casually ### decided to expound upon email@example.com the following thoughts about ### "Re: Measuring PoP to PoP latency--tools to use?": kc> how many ISPs use this and [how] do they kc> find it helps them operationally? I don't know any ISPs that us it. I imagine some enterprise networks do. I played around with it in anticipation for using it to measure jitter but found it of limited usefulness because if you have to deploy a box to do localised collection of the data anyways you may as well run a better jitter probe from that unix box. kc> it has been around for years, during which time kc> i have heard no actual data wrt its operational utility, kc> reckon that cisco would be responsive kc> to ISP suggestions for improvements to it I thought I read somewhere that Cisco was planning on dropping RTR from the featuresets. Then again, I may have just imagined that. kc> (if other router vendors have similar functionality kc> they should probably speak up; kc> we can put such features in the caida tool taxonomy) Seconded... kc> maybe a nanog panel on provider experiences/caveats kc> on any of such vendor-provided functionality kc> is not a terrible idea. kc> mod all the anxiety involved in sharing such experiences I remember at one time that on-the-router measurement features were kinda frowned upon. At least that's the general feeling I got from people.
