I have 3 questions:
1. With netflow there are settings for long flows, short flows and normal flows at the router. What is the differnce between them?
2. When I use a site like Quest to measure latency from say Orlando to D.C. and it comes back 31 ms would I then take that 31 ms and double it to calculate round trip or is it assumed that the 31ms is there and back between the 2 sites? I know it seems like a silly question but it's bugging me.
3. Is the nature of TCP such that an application will grab all bandwidth it can? For instance if I use scp from one site to another to move a large file say 1Gb and I have a 20 Mb pipe, will scp grab all the bandwidth it can get up to the amount of the pipe (if it needs to and it's available) to accomplish this transaction? I am seeing some large spikes on my network and I am wondering if I throttled down the bw would my application still perform adequately?
Any positive comments welcome.
