摘要： Method to provide video chunks to a client entity (C) using a request-response protocol. Each video chunk is available at a server entity (S) as a plurality of encoded video chunks encoded according to respective quality levels. The method includes the steps of: —the server entity sending to the client entity information on the different quality levels, —the client entity making a selection of one quality level of the different quality levels based on criteria related to local transfer bandwidth related parameters, —the client entity requesting the server entity to transfer to it encoded chunks encoded in that one chunk quality level and —the server entity sending the encoded chunks encoded according to that one chunk quality level to said client entity, —the server entity sending to the client entity additional information related to a transfer time of the encoded chunks from the server entity to the client entity, and —the client entity in making the selection of the one quality level taking into account also the additional information.

摘要： The invention concerns a method of providing resource admission control to packet flows (11, 12, 50) associated with sessions in a communication network (2), and an access controller (21, 22) to execute this method. The communication network (2) handles packets according to priority levels assigned to the packets. The priority levels comprise at least a first and a second priority level wherein the first priority level is higher than the second priority level. First, a packet flow (12) associated with the new session is identified when packets of the packet flow (12) enter the communication network (2). Preferably, the new session is a real-time session. The second priority level is assigned to the identified packet flow and the packet flow (12) is handled according to the second priority level within the communication network (2). A congestion level is measured in the communication network (2). If the measured congestion level stays below a predefined threshold, the priority level of the packet flow (12) associated with the new session is upgraded from the second priority to the first priority within the communication network (2). Once upgraded, the packet flow (12) is handled according to the first priority level within the communication network (2) until the packet flow (12) is terminated.

摘要： A sending transmission control protocol (TCP) host is used in a first network node (106) to transmit TCP flows over a network segment to a receiving TCP host in a second network node (104). The sending TCP host comprises a TCP convergence module for aggregating all TCP flows through the network segment between the first network node (106) and the second network node (104) into an aggregate TCP flow (112). The receiving TCP host comprises a TCP convergence module for disaggregating the TCP flows from the aggregate TCP flow (112).

摘要： A method of providing an Internet protocol television service to a subscriber, and a network element to execute this method. At an acquisition tier, IPTV packets are generated from video stream data of one or more video channels and transmitted to a FCC server cluster at a client-facing tier. IPTV packets associated with one of the one or more video channels selected by the subscriber are delivered from the deliver server cluster to a receiver of the subscriber at a client tier wherein the IPTV packets associated with the one of the one or more video channels are reassembled at said receiver into a coherent video stream. Said generated IPTV packets are routed from a network (5) of a TV broadcaster to networks of one or more TV operators or from a network of a TV operator to networks of one or more TV operators by means of IPTV service routers installed at an intertwine tier arranged between the acquisition tier and the client-facing tier.
