摘要： A HCPS (hierarchically clustered P2P streaming system) comprising peers grouped into clusters and hierarchies. The HCPS actively balances the uploading capabilities among clusters and executes an optimal scheduling algorithm within each cluster to ensure that system resources are optimally utilized. The HCPS comprises an architecture which can be used in practical applications, yet can achieve the streaming rate close to the theoretical upper bound.

摘要： A Bayesian Inference based recommendation system in a social network is provided. The method and system utilizes content ratings from a querying initiator's friends and their friends depending on the time to live (TTL) and other factors. Receiving users send to the querying initiator recommendation ratings from their friends and a conditional probability of distribution of the recommendation ratings given by the recommender's rooted at the friend. Once this information has been obtained from the friend/hopped friend network, the querying initiator's recommendation query engine constructs the QI's own rating response using the Bayesian Inference Network.

摘要： A method comprises associating at least one cache replacement granularity value with a given one of a plurality of content streams comprising a number of segments, receiving a request for a given segment of the given content stream in a network element, identifying a given portion of the given content stream which contains the given segment, updating a value corresponding to the given portion of the given content stream, and determining whether to store the given portion of the given content stream in a memory of the network element based at least in part on the updated value corresponding to the given portion. The at least one cache replacement granularity value represents a given number of segments, the given content stream being separable into one or more portions based at least in part on the at least one cache replacement granularity value.
