Heya,
What should I expect?
I am seeing ~350 from a vendor provided mpls cloud to a site in
Sukhrali Chowk, Gurgaon, Haryana, India
We just did a video conference between Boston and New Delhi, via NYC, and we were seeing around 250ms. However, VSNL was QoS'ing our traffic across their backbone, so I'd expect normal traffic to take a bit longer. When we originally investigated this, we were expecting to see around 300ms to 350ms.
hrm, qos doesn't necessarily mean longer RTT, it means preference in (tight/busy/hot) paths, right? So... if VNSL's network along your path is oc-48 with only 1mbps of traffic on it and you are taking only 1mbps more ... probably there isn't any change, yes? If it's a 1mbps path and you are taking 1mbps then... other folks get starved out and potentially get longer RTT. (just trying to clarify the QOS boogie-man)
