Wiimmfi/Connection Status

The Connection Status is a special feature of Wiimmfi. Server SV collects data from GPCM, MS, MASTER and NATNEG and creates 5 bit fields for each room member:

LOCAL

A bit is set, if 2 players have the same public IPv4. In this case, both clients use the same LAN and NATNEG is usually not needed. The bits are always set for both peers.

CONNECT2

A bit is set, if connection was accepted by the host. In this case the hosts sends a "GPCM STATUS type-02" message using server GPCM or MS as delivery agent. The bits are always set for both peers.

NN_CONNECT

The NATNEG server sent a CONNECT message (NATNEG connection finished) to both clients. The bits are always set for both peers.

NN_ACK

The NATNEG server received a CONNECT_ACK message of a client.

NN_SUCCESS

The NATNEG server received a REPORT message of a client with status SUCCESS. If the status is FAIL, then the related bits in NN_CONNECT and NN_ACK are cleared.

The slot index is used for the bit number. If for example players at slot 2 and 5 did NN_CONNECT, then bit 5 for player 2 and bit 2 for player 5 are set. If a player left a room (detected by GPCM or MASTER), all slot related bits are cleared.

Visualization

Server SV and mkw-ana print a summary as character vector. The following table shows the character and color selection, highest priority first:

char	description
\	Self reference and mirror line. All other bits are ignored.
▪	NN_SUCCESS and CONNECT2 are set. LOCAL is ignored.
.	NN_SUCCESS set, but not CONNECT2. LOCAL is ignored.
A	NN_ACK and CONNECT2 are set. LOCAL is ignored.
a	NN_ACK set, but not CONNECT. LOCAL is ignored.
C	NN_CONNECT and CONNECT2 are set, but not NN_ACK. LOCAL is ignored.
c	NN_CONNECT set, but neither NN_ACK nor CONNECT2. LOCAL is ignored.
L	LOCAL and CONNECT2 set, but not any NATNEG flag.
l	LOCAL set, but neither CONNECT nor any NATNEG flag.
2	CONNECT2 set, but neither LOCAL nor any NATNEG flag.
▲	All bits are cleared (not any connection).
