Abstract: 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.

Abstract: Node, computer software and method for selecting a resource that is available at multiple caches connected in a communication network. The method includes receiving from a user a request for the resource; identifying one or more caches of the multiple caches that store the resource; determining a total cost associated with a path between the user and each cache of the one or more caches storing the resource, the total cost including a static cost that reflects a topology of the communication network and a dynamic cost which is indicative of changing conditions of the communication network; and selecting one cache from the one or more caches that store the resource based on a lowest total cost of the one cache.

Abstract: A method for enabling traffic acceleration in a mobile telecommunication network. The method includes the steps of receiving, at a Radio Network Node, a reply message from a content delivery provider located outside the mobile telecommunication network; intercepting the reply message; extracting a token from the reply message; comparing the token with a stored token in the Radio Network Node; replacing in the reply message, an Internet protocol IP address of a content delivery provider server with a preset IP address corresponding to an acceleration edge server in the mobile network, when there is a match between the token and the stored token; and sending from the Radio Network Node the modified reply message to a mobile terminal.

Abstract: The present invention relates to nodes and methods for use in connection with a peer-to-peer network for sharing of data content. A priority mechanism is introduced by means of which a serving peer may select which requesting peers to serve based on their need for data content in terms of the degree of urgency. A requesting peer may include an urgency indicator in a request for data content, which for instance may be the amount of buffered data available for playback in a video buffer. The serving peer may then extract the urgency indicator from the request and apply a priority mechanism which uses the urgency indicator to select which peers to upload data content to.

Abstract: A method and network apparatus for downloading data from the network apparatus to a mobile device in anticipation of the mobile device entering a black spot zone. The network apparatus determines that the mobile device has entered a predetermined tracking zone related to the black spot zone and gathers information for defining a download zone for the mobile device taking into consideration a time necessary for downloading the data to the mobile device, and a predicted time interval until the mobile device enters the black spot zone. The network apparatus then sends the data to the mobile device when the mobile device enters the download zone.

Abstract: Differentiated Handling of Data Traffic with Adaptation of Network Address Lookup In a method of differentiated handling of data traffic, the data traffic is related to a network resource and is preceded by a lookup procedure for obtaining a network address of the network resource. A message of the lookup procedure is processed for adapting the lookup procedure. Due to the adaptation, the lookup procedure returns a network address of a replacement network resource. The replacement network resource is capable of replacing the network resource in communication of data packets of the data traffic. On the basis of the network address of the replacement network resource, differentiated handling of the data packets in said communication with the replacement network resource is accomplished.

Abstract: The present invention relates to methods and arrangements to optimize load transportation between a P2P live streaming network and an access network. The method comprises steps like: a peer in the access network selects a live channel to use; a request comprising information of the selected channel is sent from the access network to the streaming network; a converter node connecting the P2P live streaming network and the access network detects that a number of peers in the access network using the selected channel has reached a predetermined threshold value (T); and chunks that are parts of the selected channel arriving from peers in the streaming network are converted in the converter node from P2P format to multicast format.

Abstract: A method and apparatus for handing over a terminal connection. A handover request is sent from a source base station to a target base station. A first control message (including a session identifier for identifying the session, and current parameters for the session) is also sent from the source base station to a control server. If the target base station is associated with a cache storage unit containing the content data, a second control message (including a session identifier for identifying the session, and current parameters) is sent from the control server to the target base station. 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.
