The topic is SVC setup latency. Can anyone suggest what factors might effect the time it takes for an ATM switch to setup an SVC? End to end latency depends individual switch latency and the number of switches along the path, but what contributes to individual switch SVC setup latency? Inter-arrival rates of setup requests? Number of simultaneous SVCs already in service? Can anyone cite any studies that have examined the curve of SVC setup latency vs. (whatever metric is important)? Do folks have any sense whether this curve is linear (doubtful IMHO), or exponential? How it may vary from vendor to vendor depending on hardware/firmware architecture, or from switch to switch with configuration? (Yeah, I know, it sounds like I'm asking for the sun and the moon and a couple of gas giants, but I'm trying to figure out what the conventional wisdom is -- which chould probably be added to the FAQ -- and if any studies have been done.) Are SVCs just too too new (or non-existent) to have conventional wisdom? !THANKS! in advance for any citations or insights. -- John Sloan/DR32w56 +1 303 538 2746 Lucent Technologies/Bell Labs FAX +1 303 538 3155 11900 N.
