摘要： A method of measuring network performance is disclosed. A payload packet is transmitted from a sending node to a receiving node via a communication network. A reference packet is transmitted to the receiving node in connection with sending of the payload packet. Receive information related to the payload packet and to the reference packet is generated, at the receiving node. Send information related to the payload packet and to the reference packet is received, by the receiving node. Network performance is estimated by utilizing the send and receive information.

摘要： The present invention relates to methods and arrangements to optimize bandwidth usage in a Multicast Services Control System (MSCS) for digital information transport. The system comprises a service provider (Server) and service receivers (STB1-STB5) able to receive multicast streams from the service provider along multicast trees in an IP network (A/MNW). The method comprises the following steps: —A multicast join is performed by the service receivers to a multicast group associated with the service of interest provided by the service provider. —Bandwidth is measured on paths in a joined multicast tree. —Each of the service receivers (STB1-STB5) join an optimal multicast group (D1, D2, D3), which joining is based on the measurements.

摘要： The present application discloses systems and methods for adapting the rate at which the packets are transmitted. In one embodiment, the method includes: (a) receiving a packet; (b) determining whether the packet is high priority packet or a low priority packet; and (c) determining whether a transmission rate value, which defines the maximum rate or maximum average rate at which the node should transmit the low priority packets, should be adjusted, wherein the determination is based, at least in part, on whether at least some number of high priority packets and/or bits was received since a point in time; and (d) adjusting the transmission rate value if it is determined in step (c) that the transmission rate value should be adjusted.

摘要： A method of identifying traffic flows is provided in a traffic generating node, where each traffic flow is being associated with an application process running on the traffic generating node. The method is configured to perform a mapping operation, such that an application process is being linked to a signature that uniquely identifies a traffic flow and an associated socket, and such that the obtained linked information is maintained in a list. The mapping operation is configured to be executed in response to recognising a change to a socket associated with the application process at the traffic generating node. Based on accumulated mapping information, one or more processing element located at the traffic generating node, or at another node, may classify and/or control traffic flows associated with any of the application processes of the traffic generating node.

摘要： The present invention relates to methods and devices (11, 12, 14) for transmitting a sequence of data packets in a network. To this end, a send rate with which the sequence is to be transmitted is selected. Then, a first set of data packets of the sequence is transmitted and the transmission is associated with a time stamp. Finally a last data packet of the sequence is transmitted after a predetermined time interval has elapsed from the time stamp associated with the first set of data packets, where said predetermined time interval is the time required for transmitting the sequence of data packets with the selected send rate.
