No idea on the UDP packetloss on average LANs. I assume reasonably low on modern switched networks, otherwise your LAN or endpoints are too highly loaded. :).
I too am looking for an expected average. I found that from a direct link (PC to PC) packet loss occurs very rarely, although it definitely occurs. Availability was something like 99.9% at 1 kB packets @ 50 Hz.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
