Server reallocation

PartyUnit (PU):

• 1 ECU
• 512Mb RAM

Scenario

brain allocates server with 1PU brain starts funpack with 512Mb ram

funpack starts stressing brain monitors funpack stops stressing brain forgets

funpack starts stressing brain monitors funpack still stressing after x minutes

Party Cloud friendly game:

brain ups allocation to 2PUs if brain finds room on same box brain tells funpack to reallocate to 1024Mb

else brain tells pc-router that host is switching funpack detects change and messages connected clients to pause/buffer funpack exits brain starts funpack on new host funpack connects to pc-router and reconnects players

non PC friendly game:

brain ups allocation to 2PUs
