Abstract: A method performed by a network device of segmenting a corporate communications network is provided. The method comprises receiving, from a plurality of client devices in the corporate communications network, a measured value of a connectivity performance metric of a communication link over which each of the plurality of client devices has transferred data to at least one other randomly selected client device, and mapping the client devices into segments of the corporate communications network based on the measured value of the connectivity performance metric of each communication link, where two client devices communicating over a communication link having a measured value exceeding a connectivity quality measure will be mapped into a same segment. Devices for segmenting a corporate communications network are also provided.

Abstract: A network supervising device for managing distribution of data content streams in a segment of a peer-to-peer (P2P) network, comprises a processing unit which receives a request for a data content stream from at least one of the peers being constrained from uploading the data content streams to further peers, and identifies whether at least one peer exists within the network segment being capable of uploading the requested data content stream. If no peer within the segment is currently rendering the requested data content stream, the processing unit identifies whether at least one currently idle peer exists within the network segment, which is capable of uploading the requested data content stream. The processing unit then assigns to the at least one peer downloading the requested data content stream, or to the at least one currently idle peer, to upload the requested data content stream to the peer being restrained.

Abstract: The present invention relates to a method and device for distributing data content in a private network. Thus, in a first aspect of the present invention, a method is provided for distributing data content in a private network comprising a number of secondary network segments each connected to a main network segment via a virtual private network connection, which private network comprises devices for rendering the data content. The method comprises the step of arranging the devices rendering the data content as peers in a peer-to-peer (P2P) connectivity overlay network within the private network. Further, the method comprises the step of assigning a managing peer in the main network segment responsible to download the data content from a streaming source outside the private network via a gateway and to distribute the data content to at least one further peer in the main network segment.

Abstract: A method is provided for distributing data content in a P2P live streaming network comprising a plurality of peers and a streaming source periodically producing segments representing the data content to be distributed, wherein a group of the peers are assigned to download the data content from the streaming source and to distribute the data content to remaining peers. The method comprises a first peer making requests for a current segment produced by the streaming source, the requests being made at a rate higher than a rate with which the segments are produced by the streaming source. If the first peer is the first to download the current segment, then the current segment has been downloaded, wherein the network peers can download the current segment from the first peer. Otherwise, a second peer downloads the current segment and it announces this to the group on the P2P network.
