(57) Abstract :
In various exemplary embodiments, a method for the distribution of content within a network of constrained capacity uses distributed
content storage nodes functioning to achieve optimal service quality and maximum service session capacity. The method, which
functions in unicast, broadcast, switched broadcast, and multicast mode networks, uses predictions of the utility of particular content
items to download or record the highest utility items to distributed content stores during periods and in modes that will not increase
demand peaks. These predictions of utility may be based on, for example, the number of potential users, the likelihood of their use,
and the value to the service provider. The method uses signaling between network nodes to identify the best source for particular
content items based on which nodes hold that content and the nature of network constraints.
