  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. 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
