Using UNET LLAPI. At various points in the multi-player game, all clients and server are instructed to execute the NetworkTransport.GetIncomingPacketLossCount() method (i.e., monitoring network traffic/performance). Sometimes, a positive value is returned (e.g., 5). If this packet loss is on an unreliable quality of service channel, it is not a big deal and is expected. However, server and clients all have multiple channels in use configured with various quality of service settings, with a mix of unreliable, reliable and some sequenced and/or fragmented. How can it be determined if reliable data/packet is being lost?
