I have a large complicated bridged network between buildings. I have noticed periodically during the day, such as 7:20 am (probably offices logging in) and then another one at approx 6pm (I am guessing a backup of some sort) where the continuous pings I run to each of the radios goes from a 20ms or less (typical) ping response to 2000-4000ms or even lost packets. The 2000-4000ms pings can last 10-30 minutes sometimes, but my users are mad when it lasts 2 minutes. As I monitor this throughout the day, I notice the long ping times are associated with my users calling the help desk, complaining about a slow network. It appears that there is some type of traffic that causes the network to become real bad. I have been on the phone with TAC for many hours working radio configs assuming it was a radio interference problem, but I think it has something to do with some kind of bad traffic problem. One system of note is a drivers license system that was recently added. Someone told me that it was an ethernet system that someone made run on Token Ring and now put it back to ethernet. Some setting problem?? Packet size??
Back to the basic question, why do I get ping times that go to 2000-4000ms from the typical 20 ms during heavy traffic? This system runs from 6:15pm to 7:15am (13 hours at night) without a hitch...
