What is the preferred location of probes - I assume the order is IXP, ISP, Corporation and last DSL/Home users.
In my environment we mix and match :-) I've got one candy-sized on my desk in our NREN NOC office, one candy back home hanging off a (different ISP's) DSL wire, plus 2 anchors, one close to the IX and the other close to our core router(s).
Does the speed of the link make any difference to measurements (I assume it does)?
Sure, but that is one of the nice facts about this system, you get a broader view on the behaviour of the net, and from a large number of vantage points! Cheers, Wilfried
Are there any benchmark probe sources or major IXP points ?- like Vonage, Vocalocity, Youtube, Facebook, Microsoft, Yahoo , Level3, Comcast etc. networks which are running anchors or probes so that a lot of ISPs would love those ready-to-use return-path statistics.
