Using Forward Error Correcting Codes
to Speed-up Downloading from
Multiple Mirror Sites
These pages present a method developed by students attending the
laboratory of computer communication (LCCN)
to speed up downloading using the Forward Error Correction code and multiple
content servers.
Abstract
Mirror sites enable client requests to be serviced by any of a number of servers,
reducing load at individual servers and dispersing network load. Typically a
client requests service from a single mirror site. We suggest a way for the
client to access a file from multiple mirror sites in parallel to speed up the
download. We have developed a technique that can deliver dramatic speedups as
well as fault tolerance. Our approach doesn’t require a feedback from the
client to the servers, thus speeding up the process even more.
The following topics are presented:
