Title: Packet identifier (pid) aliasing for a broadband audio, video and data router
Inventor: KAKU VICKY B
IPC: H04N7/24
Filed: 2001-10-10
Abstract: An efficient, integrated solution for providing packet identifier (PID) aliasing for input transport streams, such as MPEG2 streams. MPEG packets with their original packet identifiers (PIDs) are encapsulated using a customized Internet Protocol (IP)-like scheme, and routed from an input circuit card to one or more various target processor cards in a chassis. The encapsulating packet includes a destination address field that provides source information regarding the received packet, such as a source slot and port, and the original PID. At the processor card, the source information is used by a router to look up a PID alias value, which is then inserted into another field of the encapsulating packet. The encapsulating packet is routed to a PID alias function, which replaces the original PID in the MPEG packet with the alias value. The MPEG packet is then decapsulated, e.g., for further processing on the card. The router may also look up a processing path to route the encapsulated packet on for the PID aliasing, decapsulation, and further processing, which are each provided in multiple available paths on the processor card.

Title: Delivering multicast services on a wavelength division multiplexed network using a configurable four-port wavelength selective crossbar switch
Inventor: FRIGO NICHOLAS J
IPC: H04Q11/00
Filed: 2002-01-25
Abstract: A method and a system in which selected wavelengths of a wavelength division multiplexed (WDM) signal are modulated with multicast data for multicasting data services on an optical network. The WDM signal is received from a hub node of the optical network, such as a unidirectional ring network or a bi-directional ring network. A four-port wavelength crossbar switch (4WCS) selectably switches selected wavelengths from the optical network to a modulator loop. The modulator loop includes a multicast modulator that modulates the selected plurality of wavelengths with the multicast data. Each modulated wavelength is then switched back to the optical network by the 4WCS switch, and sent to a plurality of subscriber nodes of the optical network. This architecture allows a facility provider to be physically separated from a content provider, and affords the flexibility of selectively delivering multicast content to individual subscribers.

Abstract: L'invention se rapporte à un système informatisé de fichiers qui est accessible aux utilisateurs sur l'Internet ou sur un autre type de réseau, dans lequel certains "événements déclenchants" relatifs à l'exploitation du système de fichiers génèrent automatiquement un message de notification à destination de certains des utilisateurs. Une fois qu'un utilisateur a été correctement authentifié, les droits d'accès de cet utilisateur sont évalués de manière à déterminer si l'utilisateur peut accéder aux fichiers en lecture, écriture ou lecture/écriture sur le serveur de fichiers du système de fichiers, ces droits déterminant également si l'utilisateur peut télécharger des fichiers depuis le serveur de fichiers ou à destination de celui-ci. Une fonction de notification automatique vérifie si un événement "déclenchant" est intervenu alors que l'utilisateur exécutait une tâche particulière. Cette fonction de notification automatique définit quel type exact d'événement peut devenir un événement déclenchant et définit également quelle sera l'action déclenchante, une fois que l'événement déclenchant a lieu, et elle enregistre cette information dans une base de données. Dans la réalisation préférée, ces messages de notification automatique sont transmis par courrier électronique. Grâce à l'utilisation de ces messages de type courrier électronique, le processus de notification peut être initialisé simultanément pour tous les utilisateurs qui doivent recevoir tout message de notification de ce type. La fonction d'auto-notification peut également comporter d'autres programmes qui sont lancés pour exécuter certaines tâches. Le type précis de message d'auto-notification est entièrement configurable pour chaque composant du système de fichiers. Il est possible de stocker plusieurs fichiers sous un même nom de fichier virtuel, dans la mesure où les utilisateurs individuels peuvent les déterminer. Le nom de fichier réel sur le serveur de fichiers est toujours unique pour chaque fichier individuel, et les noms de fichiers réels sont stockés dans une "table des fichiers" et les liens avec les fichiers le sont dans une base de données.
