摘要： A MPLS device which receives configuration data identifying a group of multi-labeled packets and desired EXP bits (even in the lower label entries of the label stack) for the group when forwarding the related packets. The MPLS device sets the EXP bits of even such lower label entries, and then forwards the multi-labeled packets. MPLS devices further down the path may provide different services for different multi-labeled packets depending on the EXP bit values. A service provider may configure a autonomous system border router (ASBR) to control service levels for while packets are forwarded further down the path (even in autonomous systems not related to the service provider) according to an aspect of the present invention.

摘要： A method and apparatus for routing packets through a multiport switch involves attaching indicators to packets (44) before the packets are passed through a switch fabric (40), and then using the indicators to look-up output port vectors after the packets have been passed through the switch fabric. In a preferred embodiment of a 64x64 port switch, an 8-bit output channel vector and a 15-bit output port index are attached to a packet and passed through the switch fabric. The 8-bit output channel vector directs the packet to the proper output packet processor(s) (72) and the 15-bit output port index is used to look-up an output port vector that identifies the output port(s) that will receive the packet. The method and system provide low packet overhead and flexible scaling.

摘要： Pour aiguiller sélectivement via une matrice de commutation des paquets en attente dans des modules d'entrée (IMi) vers des modules de sortie destinataires, une fonction d'arbitrage (CSC) sélectionne par cycles successifs, parmi l'ensemble des couples de modules d'entrée et de sortie, des sous-ensembles disjoints.
Chaque cycle comprend p phases successives (x) associées respectivement à p fonctions d'arbitrage.
Des unités de traitement (PUi) exécutent chacune les p fonctions, chaque fonction portant sur trois paramètres appelés "quantité requise résiduelle", "capacité d'entrée" et "capacité de sortie" dont les valeurs sont relatives à un même couple et sont initialisées en début de cycle.
Chaque phase est formée de N étapes (y) successives associées respectivement auxdits sous-ensembles, chaque étape étant exécutée en parallèle par les unités de traitement (PUi) pour calculer au moyen des fonctions d'arbitrage des valeurs de quantité admise "partielle" et pour réactualiser les paramètres pour l'étape suivante.
Application aux réseaux de télécommunication, notamment multiservice.

摘要： A monitor for and a method of examining packets passing through a connection point on a computer network. Each packets conforms to one or more protocols. The method includes receiving a packet from a packet acquisition device and performing one or more parsing/extraction operations on the packet to create a parser record comprising a function of selected portions of the packet. The parsing/extraction operations depend on one or more of the protocols to which the packet conforms. The method further includes looking up a flow-entry database containing flow-entries for previously encountered conversational flows. The lookup uses the selected packet portions and determining if the packet is of an existing flow. If the packet is of an existing flow, the method classifies the packet as belonging to the found existing flow, and if the packet is of a new flow, the method stores a new flow-entry for the new flow in the flow-entry database, including identifying information for future packets to be identified with the new flow-entry. For the packet of an existing flow, the method updates the flow-entry of the existing flow. Such updating may include storing one or more statistical measures. Any stage of a flow, state is maintained, and the method performs any state processing for an identified state to further the process of identifying the flow. The method thus examines each and every packet passing through the connection point in real time until the application program associated with the conversational flow is determined.

摘要： A method for provisioning resources in a communications network, comprising:
defining a target performance level for a specific traffic type in terms of one or more of: bandwidth, latency, security, and priority, with the target performance level being based on requirement information provided by a customer, and associating the target performance level with a user service class;
detecting a data transfer of the specific traffic type and user service class;
allocating resources to achieve the target performance level for the specific traffic type and user service class, with resource allocation including creating a virtual channel capable of satisfying the target performance level; and
transferring the data via the virtual channel to provide the defined target performance level.
