Abstract: Methods, edge routers and an edge-router-refresh network signalling message used to update state information in edge routers. A data session is established on a path from a source towards a destination connected from the source via a plurality of Autonomous Systems (AS). The edge-router-refresh network signalling message is created by an edge router acting an an ingress edge router. The edge-router-refresh network signalling message comprises an identifier of the data session, an identifier of the edge router, which issued the edge-router-refresh message and an indication that the edge-router-refresh message is meant to be used by the edge routers present on the modified path. Optionally, the edge-router-refresh network signalling message further comprises a list of the plurality of AS traversed by the path before the modification.

Abstract: Un método de desmultiplexión de instancias de servicio de Provider Backbone Bridging Traffic Engineering, PBB-TE, comprendiendo el método las etapas de: monitorizar (500) instancias de servicio entre un primer puerto de puente y un segundo puerto de puente (56) intercambiando tramas a través de cada instancia de servicio; recibir (502) las tramas por medio del segundo puerto de puente (56) desde el primer puerto de puente, y caracterizado por desmultiplexar (504) las tramas recibidas en base a una Trayectoria Conmutada de Ethernet, ESP, de 3 tuplas, mediante, desmultiplexión de una Dirección MAC de Fuente de Backbone, B-SA, a partir de la trama recibida; desmultiplexión de una Dirección MAC de Destino de Backbone, B-DA, a partir de la trama recibida; desmultiplexión de un Identificador de VLAN de Backbone, B-VID, a partir de la trama recibida, y transmisión de las tramas a distintos destinos (58, 60) utilizando la B-SA, la B-DA y el B-VID desmultiplexados.

Abstract: A method and apparatus that operates two bridging protocols in a hybrid bridging node (204D) is described. The operation of the two bridging protocols in the hybrid node allows for an incremental transition of a provider bridging network from operating a legacy bridging protocol that shares MAC addresses to a bridging network that operates VPLS and or PBB bridging protocols. The hybrid bridging node selectively broadcasts address resolution packets and unicast packets with unknown MAC addresses from the nodes operating VPLS and or PBB to nodes operating a legacy bridging protocol.

Abstract: Se presenta un sistema, método y nodo para identificar planos de control de Protocolo de Árbol de Expansión No Múltiple. El método incluye los pasos de identificar una instancia específica de plano de control de Protocolo de Árbol de Expansión No Múltiple, asociar una identificación de Plano de Control General, GCPID, con la instancia de plano de control específica, en donde la GCPID enlaza un Identificador de Área local Virtual, VID, con el plano de control específico, y anunciar la GCPID para identificar la instancia de plano de control específica.

Abstract: A network node for reserving resources for data flows in a communication network. The node detects a request for resource reservation for a new data flow and computes an admission test count based on descriptors of the new data flow and reservation counts, which represent reservation functions of descriptors of previously admitted data flows and which specify resources of the admitted data flows. The new data flow is admitted if the admission test count is smaller than a maximum allowable count. The reservation counts are then updated based on the descriptors of the new data flow. A plurality of admission formulas may thus be used to maintain aggregated reservation counts for data flows, the number of counts being independent from the number of flows.

Abstract: A method is provided for use at a first node of a network. The first node (B) has an input path for receiving Ethernet frames destined for a second node of the network. The first node (B) also has a first output (working) path for forwarding the received Ethernet frames towards the second node. A failure along the first output (working) path is detected at the first node. Following such failure detection, the received Ethernet frames are caused, at the first node, to be re-routed along a second output (backup) path, different to the first output (working) path, towards the second node. The re-routing is performed by using (e.g. referring to and/or changing) respective indications (VLAN1) applied to the Ethernet frames to distinguish those Ethernet frames to be forwarded along the first output (working) path from those Ethernet frames to be forwarded along the second output (backup) path.
