  • Publication number: 20140165118
    Abstract: The method comprises the management and delivery of a requested live stream using a P2P-based architecture, where peers exchanging content with one another are end points of a CDN. The delivery of the requested live stream to one or more end users is performed from one or more of said end points. The requested live stream is split into segments that the serving end points, preferably, obtains from neighbouring end points and/or from the origin server of the live stream using a scheduling algorithm and depending on the availability of segments thereof. The end point is designed for implementing the method of the invention.

  • Patent number: 8364758
    Abstract: A topology management process is implemented in peer-to-peer content distribution clouds using tracker nodes. Tracker nodes have information about available peers and assist peers in finding other peers to connect to. Various algorithms for use at the tracker nodes are described for selecting which peers to return as potentials for forming connections to. In addition, architectures and algorithms to allow efficient scaling of tracker nodes in peer-to-peer clouds are described.

  • Publication number: 20120209911
    Abstract: The invention discloses a method of monitoring a bittorrent network and measuring download speeds. The speed is calculated by connecting to a client, getting the bitfield and have messages, reconnecting after a predetermined time and getting a new bitfield and have messages. Taking the number of new pieces between both observations multiplied by the piece size and divided by the time between the two observations the download speed is obtained.

  • Patent number: 8140849
    Abstract: A content distribution mechanism that relies on cooperative desktop PCs to distribute content is disclosed. The mechanism distributes content in a robust manner by allowing at least one intermediate network node (i.e., between a source and client) to generate and send packets that contain a linear combination of the portions of content available at the node. Such linear combinations may be created by the source and client using at least a portion of the original content file in either encoded or unencoded form. After the client has received enough linearly independent combinations of packets, the original content may be reconstructed. Further, security for network coding file distribution may be employed to maintain the efficiency and security of the content distribution mechanism. A security server may generate security information using a hashing algorithm including the property of producing security information for each block which survives the process of creating encoded blocks.

  • Patent number: 8108362
    Abstract: The invention describes a control node for a content distribution network and a method of automatically verifying content distributed over a network at a node in the network. In the method, a content description is received which comprises a content identifier, a publisher identifier, publisher authorization information and content checking information. The integrity and validity of this information are checked and if both the checks are passed, the content description is stored.

  • Patent number: 8090861
    Abstract: Managing content by influencing its distribution in the form of blocks or other units is crucial to the performance of a peer-to-peer content distribution system. We provide a content management module at each peer node to achieve this. The content management module implements a content request/response cycle in order to negotiate about blocks of content with other peer nodes. This cycle comprises an offer request, offer reply and a block request. These steps are preferably followed by data exchange and verification. The negotiation protocol used by our content management module provides a generic method that is advantageously used in conjunction with different encoding schemes such as full network coding and group network coding. In one embodiment we use group network coding and add information to the offer request and offer reply to facilitate efficient content distribution. Block request messages are selected to promote the use of on-the-fly decoding where possible.

  • Patent number: 7912948
    Abstract: A wire protocol is described which implements connection management and other methods to give enhanced peer-to-peer content distribution. Connections between nodes can be placed in a “notify” state when they are idle but may soon yield useful content. This notify state is also used together with a content request/response cycle to allow a peer to evaluate content available at a neighbour. If no suitable content is available a notify state is entered. When new content is later received at the neighbour it is able to inform the requesting node to allow it to restart the content request/response cycle.

  • Patent number: 7849196
    Abstract: A topology management process is implemented which involves removing or “tearing down” connections between nodes in certain situations in order to try to replace those connections with more optimal ones. Idle connections are torn down unless those are in a “notify” state; a notify state being one in which a request for content has been made to a neighbour but that neighbour has no available content as yet. Idle connections in a notify state are torn down only if they remain idle for a longer time than that required before an idle connection is torn down. To avoid problems caused by clusters of node forming and of loners being unable to join the cloud, network churn algorithms are taught. These involve requiring nodes to drop connections when specified conditions are met. Relative content distribution between connections is monitored and this information used to influence selection of those connections to drop.

  • Patent number: 7680937
    Abstract: Publishing content using a peer-to-peer content distribution system is described. A publisher is required to request authorization to publish from an authorization body. Resources such as tracker and seed nodes are allocated in a peer-to-peer content distribution system and pre-processing of content to be published is carried out. For example, a content description is generated for each item of content as well as a set of checksums or other items for validating blocks of content. Publication can be terminated in a variety of different ways. For example, by using expiry methods, by active revocation of publishers, authorization bodies, or individual items of content.
