Abstract

Termination of fragment delivery services from data centers participating in distributed streaming operations, including the steps of monitoring a large-scale streaming system including a plurality of data centers comprising together a large quantity of fractional-storage CDN servers storing erasure-coded fragments encoded with a redundancy factor R greater than one and associated with approximately sequential segments of streaming contents. Identifying a data center that is still capable of delivering a substantial fragment throughput but is underperforming compared to the other centers, wherein the servers of the center store less than (1−1/R) of the fragments associated with each segment to be reconstructed. And terminating the fragment delivery service of the identified data center while maintaining continuous streaming of the contents by diverting traffic from the terminated center to the remaining centers.
