int ChannelUtil::GetBetterMplexID ( int  current_mplexid,
int  transport_id,
int  network_id 
) [static]

Returns best match multiplex ID, creating one if needed.

First, see if you can get an exact match based on the current mplexid's sourceID and the NetworkID/TransportID.

Next, see if current one is NULL, if so update those values and return current mplexid.

Next, if values were set, see where you can find this NetworkID/TransportID. If we get an exact match just return it, since there is no question what mplexid this NetworkId/TransportId is for. If we get many matches, return CurrentMplexID.

Next, try to repeat query without currentmplexid as source id. If we get a singe match return it, if we get many matches we return the first one.

If none of these work return -1.

Returns:
mplexid on success, -1 on failure.
