distributed mesh authoritative sever model

Probably an extremely noob question but been wondering this for a while.
Why isn’t there a distributed mesh authoritative sever model?
Or should I say is there one?

There doesn’t seem to be a hybrid of the p2p / dgs models and I am curious to why?

A mesh network is a topology, and typically layer 2. Was there a specific mesh network implementation, or layer 3 and up protocol stack you were targeting?

For example, you could run 802.11s with TCP/IP and use the same authoritative server network API’s already discussed here. If you don’t want to use TCP/IP you should mention what protocols your mesh network uses.

No as was leaving it open to any standard p2p/DGS hybrid system that there seems to be a lack of any, for all my limited knowledge.
Probably keeping with the standard mix of TCP/IP, UDP and STUN but multiple client server hosts mainly for multiplayer “battle” type games as they seem to be mainly a single scene of XvX players that sort of fit the role I was thinking about.

Where the hosts client never connects to the hosts server but 3 -5 remote clients do.
Your are just partitioning player objects and gameworld into groups of a number of authoritative servers of different destination address.
In essence a cluster but that is probably just more terminology to confuse what is merely client-server host fan-out.
Player objects and gameworld area are partitioned into groups and authoritative for that group and area.
If your fanout is big enough then hey you might even be able to add failover client nodes that also run the server but are just monitoring in a non authoritative backup mode.

The P2P/DGS scene seems very back and white apart from relay middleware and was wondering why as distributed ad hoc networking, file systems and resources are actually quite numerous and without focusing to much on any specific terminology I have mentioned, just the employment of anything that could partition network and server into a groups of relatively small fan-out?
Like I say a hybrid that is both P2P and also distributed partitioned DGS, it is just a topology as the network layer is likely to keep the same.
