摘要： A network device includes a multi-chassis system in which each chassis includes a RSVP-TE protocol stack that may provide RSVP-TE services for LSP tunnels associated with each chassis. The multi-chassis system may include an administrative chassis. The administrative chassis may forward RSVP messages to other chassis of the network device. The administrative chassis may encapsulate the RSVP messages with a chassis address. The other chassis may de-encapsulate the RSVP messages and process the RSVP messages according to the RSVP-TE protocol. The administrative chassis may obtain session information associated with other chassis based on RSVP messages received. The administrative chassis may manage adjacency mechanisms and failure and recovery mechanisms. The multi-chassis system including the distributed RSVP-TE protocol stacks may minimize scalability issues and improve performance when high-capacity routing and/or switching services are needed.

摘要： A unit fuel injector (30) has a nozzle (36) providing axial guidance of a needle (72) at points proximal and distal to a needle feed cavity (81). The needle has a multi-lobular formation (200) providing distal guidance of the needle while allowing fuel from the needle feed cavity to flow past for injection from orifices (86) when the needle is unseated from a seat on a tapering surface (82). Fuel is delivered to the needle feed cavity through a slant passage (85) in the nozzle non-parallel to a longitudinal axis (AX) along which the needle is displaced. The orifices are arranged in a hemispherically contoured surface (83) distal to the seat and centered on a point on the longitudinal axis. The orifices have circular transverse cross sections. The axis of each orifice extends radially of the point on the longitudinal axis at an oblique angle to the longitudinal axis.

摘要： A check valve body (44) is disposed within the interior of a main body (32) of a fuel injector (30) and contains a continuous sealing ridge for sealing a perimeter of a cavity (124) between the proximal end face of the check valve body and the distal end face of an intensifier cartridge body (46). A spring cage (42) has a proximal end face disposed within the interior of the main body. An entry check (154) is disposed in an entry through-passage (132), and an exit check (156) is disposed in an exit through-passage (130). A continuous sealing ridge seals a perimeter of an exit cavity (140), and a discontinuous sealing ridge seals a portion of a perimeter of an entry cavity (144). The sealing ridges are asymmetric about a longitudinal axis AX.

摘要： Embodiments of the present invention provide a GMPLS fast re-route of packets within a network using a multicast address and a table comprising a list of alias IP addresses. According to various embodiments of the invention an alternate data path from a source node to a destination node allows a packet to traverse to the destination node without IP forwarding techniques being applied. In other words, a tunneling effect from a source node to a destination node allows other nodes in the network to ignore the packet and only read the multicast address within the header and immediately forward the packet to the destination node. A predetermined set of IP addresses are determined from network topology including all potential paths, for a packet to traverse, to a destination address.
