The algorithm uses storage and bandwidth resources of peers to offload the cloud provider’s resources. We formulate the placement problem as a linear task assignment problem where the aim is to minimize time needed for file replicas to reach a certain desired threshold. Using simulation, We reduce the probability of a file being served from the provider’s servers by more than 97.5% under realistic network conditions. %G English %Z TC 6 %Z WG 6.1 %2 https://inria.hal.science/hal-01583581/document %2 https://inria.hal.science/hal-01583581/file/978-3-642-21387-8_16_Chapter.pdf %L hal-01583581 %U https://inria.hal.science/hal-01583581 %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-WG %~ IFIP-TC6 %~ IFIP-WG6-1 %~ IFIP-DAIS %~ IFIP-LNCS-6723
