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.

摘要： A system, method, and router for routing data packets in an overlay network built over heterogeneous layer-3 domains. A link state overlay routing protocol enables an overlay router to route data packets based on flat identifiers and decides the best path to a destination taking into account a number of parameters such as round trip time. Scalability is provided by making routing decisions based on a network identifier rather than a single end-node identifier.

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： 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： In order to put a network access node such as a wireless router or home gateway in a home network in operation, the node needs to be configured with several parameters requiring technical skills that an ordinary user often does not have. The present invention solves this problem by introducing a system and a method to assist the user to configure the router. The system comprises a web based wizard, an inference engine coupled to said wizard and a knowledge base coupled to said inference engine. The wizard guides the user to provide input which together with stored information retrieved from the knowledge base is processed by the inference engine. The inference engine further generates configuration data that is stored in the wireless router or home gateway. The user can without detailed technical knowledge easily configure the router.

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.
