Adaptation of data centers' bandwidth contribution to distributed streaming operations

摘要

Adaptation of data centers' bandwidth contribution to distributed streaming operations, including data centers comprising fractional-storage CDN servers storing erasure-coded fragments encoded with a redundancy factor R greater than one, assembling devices obtaining the fragments from subsets of the servers, and measuring fragment delivery parameters, and at least one decision component that occasionally changes at least some of the servers of the subsets to generally improve the measured parameters. Wherein the smaller the number of subsets in which the servers of a data center participate, the lower the center's fragment delivery throughput, the higher the center's cost of delivering a fragment, and the higher the likelihood of reducing the amount of bandwidth acquired from that data center by the operator of the system.
