Server SV (abbreviation for SuperVisor) is a new server created by Wiimm for Wiimmfi. It did not exist when the servers were still operated by Nintendo and GameSpy.

Overview

Server SV is a new analytic server and the central delivery agent for internal communication.

SV has permanent connections to MASTER+MS, NATNEG and some other servers. It is also connected to all GPCM instances. Server SV analyses the data of all other instances to build internal models, especially for private and global rooms of Mario Kart Wii. Some of the room statuses are delivered as Wiimmfi packets by GPCM to the clients. Tools like mkw-ana can extract the information and use them as additional source.

Another point is the gpcm-to-gpcm communication. Before SV, each GPCM instance opens a UNIX stream socket of other GPCM instances to deliver status messages. With the new SV, each GPCM instances uses only one UNIX stream socket to SV and use SV as delivery agent. Also server MASTER and the Wiimmfi portal use SV as delivery agent to e.g. kick a player.
