Accessing Multiple Mirror Sites in Parallel: Using Tornado Codes to Speed Up Downloads
نویسندگان
چکیده
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 consider enabling a client to access a file from multiple mirror sites in parallel to speed up the download. To eliminate complex client-server negotiations that a straightforward implementation of this approach would require, we develop a feedback-free protocol based on erasure codes. We demonstrate that a protocol using fast Tornado codes can deliver dramatic speedups at the expense of transmitting a moderate number of additional packets into the network. Our scalable solution extends naturally to allow multiple clients to access data from multiple mirror sites simultaneously. Our approach applies naturally to wireless networks and satellite networks as well.

Accessing Multiple Mirror Sites in Parallel Using Tornado Codes to Speed Up Downloads
This paper was published in the IEEE Infocom of 1999. The main objective, as the title suggested, is to speed up client download speed by accessing multiple mirror sites in parallel. The idea is to allow multiple senders in possession of the same file to simultaneously transmit data to the client using traditional end-to-end scheme, the data transmitted is the craftily encoded and sliced versio...

متن کاملParallel-Access for Mirror Sites in the Internet
Popular documents are frequently mirrored on multiple sites in an effort to share the load and reduce clients’ retrieval latencies. However, choosing the best mirror site is a non-trivial task and a bad choice may give poor performance. We propose a scheme in which clients access multiple mirror sites in parallel to speedup document downloads while eliminating the problem of server selection. I...

متن کاملParallelized FTP
The parallelized FTP (P-FTP) approach, attempts to solve the problem of slow downloads of large multimedia files while optimizing the utilization of mirror servers. The approach presented in this paper downloads a single file from multiple mirror servers simultaneously, where each mirror server transfers a portion of the file. The P-FTP server calculates the optimum division of the file for eff...
