Network device for transmitting packets having packet properties, including at least two input-output-buffers for queuing packets in the network device; a sojourn time calculator for calculating a sojourn related time for each head packet in the at least two input-output-buffers; a sojourn related time adaptor for, based on an adaptation function assigned to the corresponding input-output-buffer, adapting the sojourn related time into an adapted time for each head packet in the at least two input-output-buffers; and a scheduler for scheduling outgoing packets based on the adapted time.

Scheduling of packets in network devices

A method for queue management in a packet-switched network including at an intermediate node receiving first packets belonging to a first class associated with a first queue management mechanism and second packets belonging to a second class associated with a second queue management mechanism; marking or dropping of the first packets in accordance with the first queue management mechanism and marking or dropping of the second packets in accordance with the second queue management mechanism; and coupling the marking or dropping of the second packets to the marking or dropping of the first packets.

Method and system for queue management in a packet-switched network

A manner of managing congestion in a data-traffic network. In one embodiment a network node such as a bridge, switch, or router includes an AQM having a PI controller configured to calculate p' using the difference between Q and a Target Q, wherein p&#x2032; is pand p is the probability that a received packet will be dropped or marked, and some drop decision functions are configured to indicate that the node should drop a received packet by comparing p&#x2032; to two random values. A marking decision function may also be present and configured to indicate that the node should mark a received packet by comparing p&#x2032; to one random value. A congestion control classifier, which is in some embodiments an ECN classifier, is also present to classify a received packet and facilitate making the proper dropping or marking decision.

Method and apparatus for managing network congestion

The present invention is related to an intermediate node, an end node, and method for avoiding latency in a packet-switched network. According to the invention, the maximum bandwidth per flow is determined locally and transferred from the sending node to the receiving node. At each node, the information is updated if a lower local value is computed. By adjusting the transmission rate based on the maximum bandwidth per flow receiving at the receiving node, the link capacity can be optimally utilized and congestion can be minimized.

Intermediate node, an end node, and method for avoiding latency in a packet-switched network

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 () 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.
