    Abstract: A system, computer readable medium and method for providing to a user device (20) location information of a data device that provides a specific asset, where the user device (20) is present in a network (32) that includes at least a serving node (36) and an address of the user device (20) is indicative of a gateway node (35) that is different from the serving node (36). The method includes receiving at the serving node (36) a first message from the user device (20), the first message including a request for the specific asset; sending the first message from the serving node (36) to the gateway node (35); receiving at the serving node (36) a second message from the gateway node (35), the second message including a first location of a first data device (44) that provides the specific asset; modifying at the serving node (36) the second message to include an indication about a second location of a second data device (46) that provides the specific asset, where the first location is different from the second location; and sending the modified second message including the second location to the user device (20) for accessing the specific asset.

    Abstract: 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.

    Abstract: 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, epsilon, samples at different probing rates. An Expectation-Maximization, EM, analyzer utilizes an EM algorithm to identify useful strain epsilon samples and to estimate parameters of a line l2 representing a direct linear relationship between the probing rate and the inter-packet separation strain epsilon 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.

    Abstract: Un sistema y método para determinar anchura de banda disponible extremo a extremo de una trayectoria en una red de comunicación conmutada en paquete. Un inyector (12) de chirrido de paquete de múltiples regímenes inyecta paquetes de tráfico de sondeo a diferentes regímenes de sondeo, u, hacia una red que utiliza un chirrido de sondeo. Un receptor (16) muestra separación en tiempo de los paquetes de tráfico de sondeo para generar muestras de separación de tiempo, que se usan para calcular muestras de esfuerzo, e, de separación entre paquetes relativo, a regímenes de sondeo diferentes. Un analizador (17) de Maximización de Espera, EM, utiliza un algoritmo EM para identificar muestras de esfuerzo e útiles y para calcular parámetros de una línea /2 que representa una relación lineal directa entre el régimen de sondeo y el esfuerzo e de separación entre paquete a regímenes de sondeo mayores que un punto de ruptura. Un filtro, tal como por ejemplo, un filtro (18) Kalman luego determinar la anchura de banda disponible de la trayectoria de red basada en los parámetros calculados de la línea k-.
