Internet services like the world-wide web and applications like News-on-Demand have become verypopular in the last years. The number of users, as well as the amount of multimedia data downloadedby each user from servers in the Internet, is rapidly increasing. In this context, the potentially (very)high number of concurrent users that retrieve data from servers represents a generic problem. In theIntermediate Storage Node Concept (INSTANCE) project, we develop a radically new architecture...

    • ...In IN-STANCE, this redundancy is removed by integrating the error management in a disk array and a forward error correction (FEC) scheme in the communication system [5]...
    • ...Our integrated error management scheme [5] reuses parity information (calculated using a Cauchy-based Reed-Solomon erasure code) from a disk array for recovery of lost or damaged packets in a FEC scheme...
    • ...The performance analysis in [5] shows that the correcting scheme performs best using data blocks of 1 KB, 2 KB, 4 KB, or 8 KB, and we will therefore use one of these packet sizes...
    • ...Thus, as our experimental evaluati on shows [5], all the network error recovery operations are performed with a sufficient throughput to pre sent data from a high data rate multimedia stream at the client side...
    • ...Moreover, we have experimentally evaluated several possible recovery schemes for the integrated error management scheme, and we found the Cauchy-based Reed-Solomon erasure correcting code suitable [5]...
