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-.

Abstract: Information about virtual private networks—VPNs—in each domain of a multi-domain communications system is provided. By comparing a request for a configuration of a VPN with the provided information of other connected domains, a match can be found. VPN configuration can then be performed based on the outcome of the match. The provided domain VPN information is in one embodiment spread to other domains under constrictions put by SLAs between domain operators. The spreading of VPN information can be performed regularly or triggered by an external event. In another embodiment, the VPN configuration request is instead spread to different domains.
