The goal is to service a sequence of file transfer requests given bandwidth constraints of the underlying communication network. The main result of the paper is a technique that leads to algorithms that optimize several natural metrics, such as max-stretch, total flow time, max flow time, and total completion time. In particular, we show how to achieve optimum total flow time and optimum max-stretch if we increase the capacity of the underlying network by a logarithmic factor. We show that the resource augmentation is necessary by proving polynomial lower bounds on the max-stretch and total flow time for the case where online and offline algorithms are using same-capacity edges. Moreover, we also give polylogarithmic lower bounds on the resource augmentation factor necessary in order to keep the total flow time and max-stretch within a constant factor of optimum."}],"oa_version":"None","_id":"11691","doi":"10.1145/301250.301300","conference":{"start_date":"1999-05-01","end_date":"1999-05-04","name":"STOC: Symposium on Theory of Computing","location":" Atlanta, GA, United States"},"author":[{"last_name":"Goel","full_name":"Goel, Ashish","first_name":"Ashish"},{"id":"540c9bbd-f2de-11ec-812d-d04a5be85630","last_name":"Henzinger","orcid":"0000-0002-5008-6530","first_name":"Monika H","full_name":"Henzinger, Monika H"},{"full_name":"Plotkin, Serge","first_name":"Serge","last_name":"Plotkin"},{"last_name":"Tardos","full_name":"Tardos, Eva","first_name":"Eva"}],"quality_controlled":"1","scopus_import":"1","title":"Scheduling data transfers in a network and the set scheduling problem","citation":{"apa":"Goel, A., Henzinger, M.
