摘要： There is described a client node for use in a network. The client node comprises a transmitter for requesting data from the network. A processor is operatively connected to the transmitter, and has installed thereon an operating system and an application. A receiver for receiving data from the network is operatively connected to the processor. The application is arranged to request content data from the network by opening a transport socket to the operating system. The operating system is arranged to establish contact with a master peer server in the network, receive a list of sources of the content data from the master peer server through such transport socket signalling, and establish contact with at least one source from the list of sources. The application is arranged to receive the content data from the at least one source without being aware that the content is delivered by at least one source from a list of sources. The list of sources may include nodes in a P2P network.

摘要： There is described a method and apparatus for handing over a terminal connection from a source base station to a target base station in a packet data network when the source base station is acting as a caching server and sending content data towards the terminal. A handover request is sent from the source base station to the target base station. A first control message is also sent from the source base station to a control server, the first control message including a session identifier for identifying the session, and current parameters for the session. If the target base station is associated with a cache storage unit containing the content data, a second control message is sent from the control server to the target base station, the second control message including a content identifier, the session identifier and the current parameters. At the target base station, the content data packets are retrieved from the cache storage unit, and a header of each retrieved content data packet is populated with parameters calculated using the received current parameters and session identifier. The content data packets are then sent from the base station towards the terminal.

摘要： Methods and nodes (200, 202) in a data distribution network, for distributing content to multiple consuming nodes (C1, C2, C3,...). A first node (200) detects (2:2) multiple data flows (2:1b) of a first content from the first node to a second node (202) in the distribution network, when the first node operates as delivering node of the first content for the consuming nodes. The first node then instructs (2:4) the second node to operate as delivering node of the first content for the consuming nodes and redirects (2:5) the consuming nodes to use the second node as delivering node of the first content. The first node further reduces (2:6) the multiple data flows to a common data flow of the first content to the second node. Thereby, efficiency can be improved in the data distribution network by reducing the number of data flows between the first and second nodes.

摘要： A method and a cloud management node (200) for enabling usage of a virtual machine in a distributed cloud of resources for processing and storing of data. When receiving (2: 1 ) a VM image from a client (202) with a set of files of an operating system for running the virtual machine, the cloud management node distributes (2:2a-d) the VM image (204b) to a plurality of local data centers (204) forming the distributed cloud. In return, the cloud management node receives local identifications of the VM image from the local data centers, and creates (2:3) a mapping (200a) between the received local identifications and a global identification of the VM image. The global identification is then returned (2:4) to the client, thereby enabling the client to change the VM image in the local data centers by referring to the global identification in communication with the cloud management node.

摘要： There is described a method and apparatus for sending data through one or more packet data networks. A stripped-down packet is sent from a packet sending node towards a cache node, the stripped-down packet including in its payload a pointer to a payload data segment stored in a file at the cache node. When the stripped-down packet is received at the cache node, the pointer is used to identify the payload data segment from data stored at the cache node. The payload data segment is inserted into the stripped-down packet in place of the pointer so as to generate a full size packet, which is sent from the cache node towards a client.

摘要： There is described a system and method of handing over a connection to a terminal from a source network element (e.g. base station) to a target network element ( e.g. base station) in a packet data network when the source base station is acting as a caching server and sending content data towards the terminal in a session. A handover request is sent from the source base station to the target base station. A context data message ( e.g. CXTP message) is sent from the source base station to the target base station, the context data message including session state parameters identifying the state of the session. At the target base station, the session state parameters are retrieved from the context data message and used to identify the state of the session. Content data packets are then sent from the target base station towards the terminal so as to continue the session.
