摘要： 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.

摘要： The invention relates to a method and system hardware for ingesting media content in a peer-to-peer network from a data stream. The data stream is made up of a sequence of packets of media data, and each packet is identified by a sequence identifier. The method includes commencing caching of the data packets from the data stream. A missing data packet is identified using the sequence identifiers of the packets and the size of the missing data packet is determined. A portion of the memory medium is skipped to provide a skipped portion of medium having no data cached therein. The skipped portion has a size corresponding to the determined size of the missing data packet. The missing data packet is then retrieved and inserted into the skipped portion of the memory medium. The system includes an ingestion element configured to receive the content in a data stream, to define blocks of media data that make up the content, to generate metadata associated with each block, the metadata identifying the construction of the block from the data stream, and to transmit the data stream as a multicast stream to other network nodes. The other network nodes include at least one cache element configured to construct at least one of the blocks from the multicast data stream in accordance with the metadata, and to cache the data block. The system also includes a database accessible to network nodes, the database recording a location of each of the cached data blocks in the network.

摘要： A method, network, and node for distributing content across a plurality of content cache nodes to provide optimal access to the content. Relevant, e.g. popular, content is distributed as close as possible to the user or group of users that have the highest probability of requesting the content. In addition, content is relocated to caching nodes higher in the aggregation network as content become less demanded, e.g. less popular. Portions of the content are distributed in a plurality of content cache nodes, and locations where particular portions of the content are requested by users with greater frequency than other locations are determined. The content portions are then migrated to content cache nodes closer to the locations where the particular portions of the content are requested by users with greater frequency.

摘要： According to a first aspect of the present invention there is provided a method of distributing data to peers of a peer-to-peer network to enable those peers to provide data to other peers. The method comprises predefining a minimum number of peers that are required to store a data item, sending the data item to a number of data receiving peers from one or more data servers, determining if the number of data receiving peers that have sufficient storage capacity available to store the data item is less than the predefined minimum number, and, if it is, deleting previously stored data to make sufficient storage capacity available.

摘要： A method of merging Distributed Hash Table (DHT) rings in heterogeneous network domains, where each domain includes a DHT ring. Upon determining that a node is common to first and second DHT rings on the same hierarchical level and having at least one Overlay Router in common, a link is started between a node in the first DHT ring and a node in the second DHT ring by establishing an indirect link through the common node. An indirect link is created between the first and second DHT rings, and virtual links are created to DHT rings positioned higher in the DHT ring hierarchy until all the DHT rings are merged into a single logical ring.

摘要： The present invention relates to a method and arrangement of facilitating the establishment of peer-to-peer IP connections between a public network and hosts in a private or home network. The method uses a port mapping table residing in a NAT that maps external public IP addresses and external port numbers to private IP addresses and internal port numbers. This table has so far been configured manually by a user of the private or home network. Apart from being cumbersome, it demands skills in router and network technology, skills an ordinary user of a home network often does not have. The present invention solves this problem by automatically configuring the table comprising the steps of scanning the hosts using a port scanner and detecting the internal ports in the hosts that are in an open state.

摘要： The present invention relates to a server and a method for achieving a fast channel change in e.g. an IPTV system. This is achieved by selecting a source for retrieving the requested channel based on the current load of the FCC server. The source may be the streaming server providing the regular multicast stream or a buffer providing a buffered version of the requested channel. According to one embodiment requests for fast channel change (relating to the same channel) are grouped and served and served as a bundle over multicast. By doing that one can alleviate the load on the FCC server and the network since multiple clients can share the same stream.

摘要： A system and method for managing content data transfers in a peer-to-peer communications network is described. The system includes a hierarchical arrangement of tracker modules, each tracker module being responsible for managing a tracker domain of network elements. Each tracker module has stored therein a content table including a record of content data available to the network elements within its respective tracker domain. Each tracker module responsible for a tracker domain containing end user peers is configured so that, if a content data request is received from a requesting peer in its respective tracker domain and the requested content is held by other peers in that tracker domain, a list of peers having the content data stored thereon is sent to the requesting peer. If the requested content is not held by enough other peers in that tracker domain, the content data request is transferred to the next tracker module up in the hierarchy.
