  • Publication number: 20150121473
    Abstract: In the method an Access Point comprises aggregating spare bandwidth of at least another Access Point and capturing data traffic from at least one user computing device, said user computing device taking benefit of said aggregated spare bandwidth. The method: requesting, by said Access Point admission to a MPTcp server including proxy control functions or services, to make use of the latter; checking, by a control module of said MPTcp server, credentials information of said Access Point to allow the latter said admission; and upon said admission being authorized, checking, by said MPTcp server through a connection with a service subscription repository module, if at least one origin server is authorized for accessing said proxy control functions or services. The system is adapted to implement the method.

  • 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.
