20110202652 | METHOD AND APPARATUS FOR MONITORING A KAD NETWORK - A method and apparatus are described including determining if a received message is from a monitored peer, forwarding the received message to a coordinator responsive to said determination, determining if the received message is a request message, opening a port for the peer responsive to the second determination, forwarding the request message to a monitored peer via the opened port and forwarding a response message to the monitored peer responsive to the second determination. | 08-18-2011 |
20120005304 | METHOD AND APPARATUS FOR SCALABLE CONTENT MULTICAST OVER A HYBRID NETWORK - A method and apparatus are described including receiving content from a base station, storing the received content, receiving a second message from a first member of a network, determining a highest expected layer, a lowest layer received by the first member of the network requesting help, a highest layer that needs to be multicast to the first member of the network, and a lowest layer that needs to be multicast to the first member of the network, retrieving the stored content responsive to the message and multicasting the retrieved content to the first member of the network responsive to the determining act. | 01-05-2012 |
20120110609 | METHOD AND APPARATUS FOR PEER-TO-PEER STREAMING OF LAYERED CONTENT - A method and apparatus are described including receiving buffer maps of neighbor peers, measuring serving rates from the neighbor peers, measuring serving rates to the neighbor peers, requesting a unit of data from one of the neighbor peers responsive to information in the buffer maps of the neighbor peers at a rate responsive to the serving rate from the one of the neighbor peers, receiving incoming requests for units of data, sorting the incoming requests into a plurality of queues, selecting one of the incoming requests to serve responsive to the serving rates to the neighbor peers corresponding to the incoming request, updating the queues and selecting a new neighbor peer. | 05-03-2012 |
20130041862 | METHOD AND SYSTEM FOR PROVIDING RECOMMENDATIONS IN A SOCIAL NETWORK - 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. | 02-14-2013 |
20130262681 | APPARATUS AND METHOD FOR PROVIDING SERVICE AVAILABILITY TO A USER VIA SELECTION OF DATA CENTERS FOR THE USER - A capability is provided for improving service availability experienced by a user requesting access to a service via a user device, where the service has multiple service instances available from multiple data centers. A set of servicing data centers is selected for the user device. The set of servicing data centers is selected from a set of candidate data centers. The set of servicing data centers is selected from the set of candidate data centers in a manner for maximizing the independence/orthogonality of the network paths between the user device and the servicing data centers. The set of servicing data centers includes two or more of the candidate data centers from which the user device may access the service, thereby providing the user device with a primary service instance and one or more backup service instances which may be used to access the service. | 10-03-2013 |
20140089452 | CONTENT STREAM DELIVERY USING VARIABLE CACHE REPLACEMENT GRANULARITY - 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. | 03-27-2014 |
20140189707 | Virtual Machine Placement in a Cloud-Based Network - Methods and apparatuses for real-time adaptive placement of a virtual machine are provided. In an embodiment, a virtual machine is received at a routing component, the routing component having a processor in communication with a memory. By the processor in communication with the memory, a target data center is determined from a plurality of data centers based on a data center index, and the virtual machine is routed to the target data center. A physical machine is chosen within the target data center for placing the virtual machine. | 07-03-2014 |
20140195612 | QUEUE-BASED ADAPTIVE CHUNK SCHEDULING FOR PEER-TO-PEER LIVE STREAMING - A method and apparatus are described for scheduling content delivery in a peer-to-peer network, including receiving a message from a peer, classifying the received message, storing the classified message in one of a plurality of queues based on the classification, generating responses to messages based on a priority of the queue in which the classified message is stored and transmitting content to all peers in the peer-to-peer network. Also described are a method and apparatus for scheduling content delivery in a peer-to-peer network, including receiving one of a message and content from one of a content source server and a peer, classifying the received message, storing the classified message in one of a plurality of queues based on the classification, storing the received content, generating responses to messages based on a priority of the queue in which the classified message is stored and transmitting content to all other peers in the peer-to-peer network. | 07-10-2014 |
