摘要： A method and system for routing data in a content distribution network (network) from a plurality of content sources that store the same data to a receiving device, including generating a network topology in which each of the content sources that store the data are represented as virtual routers that are each connected to a common virtual content server by respective infinite capacity communication links; determining optimized routing through the network topology for the data from the virtual content server to the receiving device; and determining, in dependence on the optimized routing, a data allocation for each of the content sources to transmit data through the network to the receiving device.

摘要： A method and apparatus for deploying a set of network caches in a communication network is provided. A set of network nodes is identified such that, for each of a set of client device locations, and for at least a number c of the set of nodes, output of a coverage cost function is no greater than a threshold. The coverage cost function receives as input a client location and one of the nodes. The set of network caches are then located at the respective set of nodes. The set of network nodes can be selected from plural candidate sets based on a utility criterion. The candidate sets can be generated by successive addition and/or removal of nodes. Information obtained from a Traffic Engineering function can be used to direct selection of the set of nodes. A cache-client association can be generated for directing clients to particular caches.

摘要： Systems, devices and methods are provided for incorporating a quality of experience (QoE) assessment into requests or negotiations for a particular quality of service (QoS) for an application in a communications network. A network may provide service in accordance with a particular set of QoS parameters in order to meet a user's requested QoE. A user may select a particular QoE for an application depending on costs associated with the corresponding sets of QoS parameters available from the network. Functionality to determine the correlation between a user's QoE and sets of QoS parameters may be implemented primarily in a user's electronic communications device, primarily in a network device, or in both of these devices. A separate device may be used for determining the QoE and corresponding sets of QoS parameters for various services or applications.

摘要： The present disclosure concerns the harnessing of the effect of a relay to enhance the ability to avoid the effect of interference at mobile stations. This is achieved either by overlaying beamforming for an indirectly reached mobile station so that a relay passes on this beamforming to the mobile station concerned, and retaining orthogonality therewith, or by harnessing a base station and a relay station together so that their combined effect is to provide spatial multiplexing to two or more mobile stations.
