Co-Allocation & Advance Reservation Co-allocation is necessary because applications need simultaneously resources of different types: CPU and DATA and NETWORK Advance Reservation of heterogeneous resources is necessary to guarantee end-to-end performance Analysis of possible strategies and paradigms for rescheduling in case of resource fault or change in allocation The different architectural approaches have to be investigated: Reserv/co-alloc done by application Reserv/co-alloc agents between appl and res.
