A server query protocol is a protocol that facilitates querying information from a server. Multiplay Hosting requires all builds to implement a server query protocol. Multiplay Hosting uses the information supplied by the server query protocol to: The analytic data is available per fleet and per server. The query protocol type might include concurrently connected players (CCU), players per platform, total available server slots, and current map. The recommended protocol is SQP, which integrates well with Multiplay Hosting. It's supported by both the Unity and Unreal Engine SDKs. Multiplay Hosting supports A2S. This might be beneficial if you're already using a library providing A2S, such as the Steam SDK. In future, this might not have feature parity with SQP.
