Abstract
Load-balancing an asymmetrical distributed erasure-coded system including fractional-storage CDN servers, storing, at a high storage gain, erasure-coded fragments encoded with a redundancy factor greater than one from segments, and a plurality of assembling devices, each obtaining fragments from a subgroup of the servers. The subgroups are selected from the servers still capable of increasing their fragment delivery throughput. Wherein not all of the servers have the same fragment delivery bandwidth capability, and the storage gain of each segment on each server is usually not strictly proportional to the bandwidth capability of the server, and the aggregated throughput used by the servers to deliver fragments may approach the aggregated bandwidth capabilities of the servers.
