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： A method of enabling traffic flow classification on a node, which may be used for controlling the traffic flows on the same node or on another node of a communication network. A first mapping process is configured to manage an operation for linking an application process to a class, and a second mapping process is configured to manage an operation for linking an application process to a unique signature. A third mapping process is configured to manage a record of accumulated linking information, such that a traffic flows associated with an application process may be identified and such that a classification of the respective traffic flow can be recognised. The accumulated classification information may then be used for controlling purposes.

摘要： A probing method, arrangement, and system for estimating a condition, such as available bandwidth, of a data path in a communication network including multiple nodes are described. A probe-packet sender node transmits probe packets with a sent inter-packet separation and a time-to-live towards an intermediate node. Control message packets are generated by the intermediate node when the time-to-live expires. The probe-packet sender node receives the control message packets and calculates a received inter-packet separation. An estimate of the data path condition can be generated based on the sent inter-packet separation and the received inter-packet separation.

摘要： A system and method for determining end-to-end available bandwidth of a path in a packet-switched communication network. A multi-rate packet chirp injector injects probe traffic packets at different probing rates, u, into the network utilizing a probe chirp. A receiver samples time separation of the probe traffic packets to generate time-separation samples, which are used to calculate relative inter-packet separation strain, ε, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain ε samples and to estimate parameters of a line l2 representing a direct linear relationship between the probing rate and the inter-packet separation strain ε at probing rates greater than a break point. A filter such as, for example, a Kalman filter then determines the available bandwidth of the network path based on the estimated parameters of the line l2.
