Re: Network Acceptable Parameters for Applications- WAN
For network application, per QoS model the most important parameters are (you noted almost all of them):
tolerance to latency;
allocated bandwidth per session/user (capacity management);
tolerance to packet loss.
If you are using any "industrial" device to communicate over WAN, then I would also ask for MTU requirements (it could be using UDP, or had no PMTU discovery) and any known issue related to packet reordering.
If you are using MPLS, then (almost for sure) it's possible to request provider for QoS.
After you have all the requirements from application vendor, you could design your QoS with ISP.
PS: I would recommend to ask vendor for any example of simular implementation.
PS2: try the application on some pilot sites before enterprise-wide rollout.
PS3: if you are using poor Wireless design (inside your LAN), then it could be a bottleneck for the applications regardless of WAN link quality.
