Abstract: The present invention provides an apparatus for reporting about a download of an item of digital data to an end user from a plurality of logged data sources. The item of digital data is downloadable in one or more sessions but also divisible into portions. The apparatus comprises multiple event logs being associated with the logged data sources of the plurality of logged data sources. The apparatus further comprises a retrieving device for retrieving the multiple event logs from the logged data sources. The apparatus further comprises multiple event logs indicating the portions of the item of digital data downloaded in at least one of the one or more sessions. The apparatus further comprises a reporting device for combining the at least one event log and producing a report of the download of the item of digital data.

Abstract: A method for the distribution of digital objects in a peer-to-peer network is disclosed. The digital objects are distributed in a plurality of pieces. At least some of a plurality of peers are connected to other ones of the plurality of peers and at least one of the peers is connected to at least one cache.

Abstract: A network and method for the delivery of digital data is disclosed having at least one peer (102a) downloading the digital data from a plurality of data sources (102, 312), at least one data monitoring device (800) for monitoring at least one quality of service parameter for the delivery of the digital data and at least one data delivery controller (810) for adjusting at least one of the rates for the delivery of the digital data from at least one of the plurality of data sources (102, 312).

Abstract: A method and apparatus for the delivery of digital data to an end user (902) from a network (900) comprising at least two different data sources (912a, 912b) is disclosed. Each of the at least two different data sources (912a, 912b) can deliver the digital data to the end network at at least one parameter and the data sources (912a, 912b) have substantially identical copies of the digital data comprising portions and are connected to the end user (902). The method comprises receiving (1011) a list of a subset of the at least two data sources (912a, 912b) and selecting (1012) on the basis of the list one or more of the subset of at least two data sources (912a, 912b). At least a portion of the digital data from the selected ones of the at least two data sources (912a, 912b) is delivered to the end user (902).
