Query Regarding QOS
« on: June 25, 2007, 07:31:28 am »
Hi all,
I would like to know some stuff regarding QOS.
1)Does QOS happen at Layer2 or Layer3?
2)Does end device like IpCamera or IpPhone tag the QOS or the Edge Switch to which those devices are connected to?
3)What is difference between QOS and COS?
4)Are there any well defined QOS values for Video and Voice?
More questions once i get these cleared.
