5. 5 Login Process User sends login request to a server Server performs –AAA – Service Layer –GS selection – SVC and DPC –Redirecting to selected GS Selected GS –Resource allocation –User state setup –Session lookup/Join/Creation – Done by app with the help of SVC and DPC –Notifies other relevant GSs Session – logical game maintained collaboratively by GSs

6. 6 Handling Migration/Roaming Initiated by application –Application asks Service to lookup a new server satisfying certain criteria –Service may rely on info from DPC for the selection Initiated by DPC –For load balancing, failure recovery –Has to preserve application state –Application register with Service a callback function –Service calls back when notified by DPC of certain event –Application has a chance to transfer user state to new server
