摘要： A peer-to-peer communication optimizer uses both peer locality and content diversity in a peer group to reduce network usage cost associated with using remote peers in a peer-to-peer system while reducing impact on the download time relative to peer-to-peer protocols operating with locality optimization alone or no localization of peers. The optimizer intercepts control messages in the peer-to-peer system and substitutes peer lists that meet both diversity indicator and network usage cost thresholds. Transparent embodiments operate without requirement to change peer or tracker implementations. Such embodiments include control message redirection, interception, and modification transparent to the client and tracker applications. Other embodiments include proxy designation. Still other embodiments include the use of gateway peers selected as function of diversity of content and network topology. Still other embodiments involve modification to one or more of client and/or tracker software and potentially the use of a standard interface for network topology determination.

摘要： The present invention relates to a system and method for controlling peer-to-peer connections in a Peer-to-Peer (P2P) streaming application for individual Internet Service Provider (ISP) networks over a localized overlay. The system may include a tracker local to a first ISP network configured to select edge peers among local peers of the first ISP network. The selected edge peers have external connections to peers outside the first ISP network in order to transfer sub-streams to or from the first ISP network, and the local peers not selected as edge peers have internal connections to other local peers within the first ISP network to transfer the sub-streams over the localized overlay.

摘要： The present invention relates to a method for filtering a multiplexed packet stream in a network entity of the core network or the radio access network of a mobile communication system. The multiplexed packet stream provides a multicast or broadcast service and is delivered from a service center via the network entity to a mobile terminal. Further, the network entity comprises a service manager providing a quality-of-service management function. The invention further relates to a network entity provided with filtering capabilities, as well as to a communication system comprising the network entity. To provide an adaptive multimedia broadcast/multicast service QoS architecture that is scalable to a great number of users the invention suggests providing the service in form of a multiplexed packet stream via a single bearer service an equipping nodes within the distribution tree of the service filter capability allowing to filter the multiplexed stream based on the downlink quality-of-service constraints obtained from a service manager.

摘要： A method and apparatus for peer-to-peer file sharing is provided. In some embodiments, the method includes receiving a request for a list of neighbor peers, where the request is made by a requesting peer device, and where the requesting peer device has a local internet service provider (ISP). The method may also include employing a server device to rank each neighbor peer in a plurality of neighbor peers based on whether the respective neighbor peer is external to the local ISP, and if the respective neighbor peer is external to the ISP, further based on a cost metric associated with a next ISP hop from the requesting peer device to the respective neighbor peer. The method may also include generating the list of neighbor peers based on the ranking of the neighbor peers, and enabling transmission of the list of neighbor peers to the requesting peer device.

摘要： The invention relates to a method for filtering and a network entity of the core network or the radio access network of a mobile communication system filtering streams belonging to a single user service. The packet streams, each being transported by a bearer service, provide a multicast or broadcast service and is delivered from a service center via the network entity to a mobile terminal. The network entity comprises a service manager providing a quality-of-service management function. The invention further relates to a communication system comprising the network entity. To provide an adaptive multimedia broadcast/multicast service QoS architecture that is scalable to a great number of users, the invention suggests providing the service in form of a packet streams, each being provided via a single bearer service, and equipping nodes within the distribution tree of the service filter capability allowing to (de)register bearer services providing the service based on the downlink quality-of-service constraints obtained from a service manager.
