Abstract
The large variety of devices that are gaining access tothe Internet requires novel server functionalities to tailorWeb content at run-time, namely transcoding. Traditionalschemes assign transcoding operations to the Web server orsingle edge proxies. We propose an alternative architectureconsisting of cooperative proxy servers which collaboratein discovering and transcoding multiple versions of Web objects.The transcoding functionality opens an entirely newspace of investigation in the research area of cache cooperation,because it transforms the proxy servers from contentrepositories into pro-active network elements providingcomputation and adaptive delivery. We investigate andevaluate experimentally different schemes for cooperativediscovery of multi-version content and transcoding in thecontext of a flat topology of edge servers.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
