The invention relates to a method of performing multicast admission control in a communications network (), comprising the steps of: a) receiving, at a first node (-) of the communications network (), a request () for a multicast channel () from a host system () communicatively coupled to the first node (-); b) sending, by the first node (-), a request () for the multicast channel () to a central admission controller () of the communications network (), the sending of the request () being triggered by receiving the request () from the host system (); c) determining, by the central admission controller (), if sufficient resources exist on nodes (-to-) and interconnecting links (to, T) of the communications network () to provide the requested multicast channel () from a source () to the host system (); and d) in case that sufficient resources exist, installing on the nodes (-to-) having sufficient resources to provide the requested multicast channel () to the host system (), a replication rule for the multicast channel (). The invention further relates to a central admission controller () and to a communications network ().

A method for reconstructing torrent content metadata, i.e. a torrent identifier, a segment length and an amount of segments of a torrent content file, without access to the torrent content metafile, comprises the steps of: A. obtaining the torrent content identifier from torrent signaling from a client; B. obtaining a torrent content file size from said torrent signaling from said client; C. obtaining a tracker address from said torrent signaling from said client: D. obtaining a peer address from a tracker; E. contacting a peer via the peer address; F. downloading sequential minimum size blocks of a full size segment from the peer in order to determine the segment length; G. calculating the amount of segments from the torrent content file size and the segment length.

The invention relates to providing network access to separate virtual private network. It relates to a method for proxying user authentication-authorization-and-accounting messages via a network access server (NAS) and at least two separated virtual private networks (VPNs), wherein a first VPN has it's own first authentication-authorization-and-accounting server (AAA server), and a second VPN has it's own second AAA server, comprising the steps of: Further it relates to a network access server, an authentication-authorization-and-accounting server, and computer software products for proxying user authentication-authorization-and-accounting messages via a network access server.

A method for deploying a service in a communication network by performing the steps of: invoking a service deployment engine by a request for the service, retrieval of deployment templates, retrieval of service deployment policies, determination of a current configuration of at least one network element involved in providing the service, and selection of a deployment template from the retrieved deployment templates based on the service deployment policies and configuration. Further, a method for configuring a network element via a network element controller through the intermediary of a network element proxy.

A method of establishing a voice/data call between at least two subscribers is disclosed. Prior to the establishment of the connection between subscriberand subscribervia exchanges, a first time window is inserted in which subscriberrequests specific execution of the call to be established.

A method for generating an updated video stream from an incoming video stream for use in image encoding applications includes the steps of replacing each predetermined reference frame amongst a second plurality with an updated reference frame, obtained by temporal filtering of a first plurality of frames from said incoming video stream at positions dependent on the position of said each predetermined reference frame. If afterwards encoded using an encoding algorithm using the updated reference frames as reference frames, the thus encoded updated video stream will show a reduced peak-to-mean bitrate ratio compared to the encoded original video stream. An apparatus for performing this method is described as well.
