Abstract: A method or corresponding apparatus in an exemplary embodiment of the present invention monitors an operational status of network links and retrieves or receives the operational status. The operational status is stored (e.g., within 50 msec) on an ongoing basis. The operational status corresponds to an operational LSP from among a primary LSP and secondary LSP(s) used to service traffic via the network links to maintain network connectivity via the LSPs. The secondary LSP(s) may be either a bypass LSP or a backup LSP, where each LSP is Fast Re-route (FRR) enabled. Further, correspondence between the primary LSP, secondary LSP(s), and the network links may be tracked. In order to deliver network traffic via the operational LSP known to service traffic between the source and destination, a link identifier may be used. The link identifier is determined from the source and destination information within the network traffic.

Abstract: L'invention concerne des procédés et un dispositif de stockage, de manipulation, d'extraction et d'acheminement d'état, par exemple, un contexte et d'autres informations, qui servent à prendre en charge des sessions de communication avec un ou plusieurs noeuds terminaux, notamment des dispositifs mobiles. Diverses caractéristiques concernent un noeud mobile qui commande le transfert d'état d'un premier noeud d'accès à un second noeud d'accès au cours d'une opération de transfert de manière à éliminer la nécessité de transmission des messages de transfert d'état entre le second noeud d'accès et le premier noeud d'accès lors du transfert. D'autres caractéristiques de l'invention concernent l'utilisation d'un noeud de réseau central pour stocker les informations d'état. L'accès et l'utilisation, par des noeuds d'accès, des informations d'état stockées dans le noeud central sont possibles dans le cas où un noeud mobile ne transmet pas un message de transfert d'état lors du transfert, par exemple, en raison de la perte de communication avec le premier noeud d'accès ou de l'absence de prise en charge de ce type de messages.

Abstract: Group communications methods and apparatus are described. Multicast operation is supported with the transmission characteristics (1003, 1052), e.g., transmission power level, coding rate, and/or modulation method being selected to reliably communicate information to the end nodes (134, 136, 144, 146, 154, 156) in the group but not necessarily to all end nodes within the cell or sector (138, 148, 158). Thus resources can be conserved by matching transmission requirements with information on the requirements of one or more group members. The requirements for reliably reaching the end node with the worst channel conditions can, and in some embodiments is, used to determine the group transmission requirements. Power level and other transmission resource allocations can change in response to changes in group membership and/or conditions corresponding to existing group members.

Abstract: The present invention relates to a method of and a corresponding system for reducing fuel consumption and environmental impact in a two-stroke engine, comprising the steps of obtaining system oil/consumable system oil (301') from at least one engine (300), adding (102) at least one friction modifier (101) to at least a part of the obtained system oil/consumable system oil (301'), where the addition of the at least one friction modifier (101) reduces the friction coefficient of the obtained system oil/consumable system oil (301'), resulting in a system oil/consumable system oil with reduced friction (301 "), and supplying said system oil/consumable system oil with reduced friction (301 ") to said at least one engine (300). In this way, frictional losses caused by contamination of the system oillconsumable system oil are avoided or minimised, which normally take place as the oil is used and which would otherwise cause a continuous decrease in engine efficiency resulting in increased fuel consumption and emissions. In addition, the present invention related to a method and a corresponding system to convert system oil/consumable system oil into cylinder oil. Finally, the present invention relates to a method to use a consumable system oil as it is being converted into cylinder oil. This furthermore allows for the consumable system oil to contain a lower performance additive package and/or additive treat rate. Thus great economical savings and environmental improvements are achieved.
