摘要:
To activate respective OSs separately through a network even in a virtual machine in which a plurality of OSs are installed, an M-packet acquiring unit acquires a received magic packet. An address detecting unit detects a MAC address that is stored in the magic packet. A control-list storage unit records correspondence between MAC addresses and guest OSs, and defines whether to activate the respective OSs by a remote operation. An activation determining unit refers to the control-list storage unit and determines whether to activate a guest OS that corresponds to the MAC address stored in the magic packet. A guest-OS control unit activates a guest OS that is determined to be activated by the activation determining unit.

Control messages for securing a communication quality are exchanged via a dedicated connection within an ATM network when a sending terminal in an IP network delivers data to a receiving terminal in another IP network via the ATM network. A resource reservation message sent from the receiving terminal is parsed by a boundary device located at the boundary between the IP and the ATM network, and a data transfer connection is established within the ATM network based on the information of the resource reservation message.

A storage unit includes an alarm state/timer table, an alarm state table, an alarm state OR-representation table, an alarm state change OR-representation table, an alarm state latch circuit, and a statistical information memory. A collection unit extracts the identifier and data from a cell that passes through a switching unit. An update unit updates associated data in the storage unit. A readout unit reads the updated data and sends it to a call processing processor. An address generation section selectively generates the address for data needing to be updated. An adjustment section forces the readout unit to wait until a cell slot arrives in which no data is updated.

Provided are a small-sized, low-cost, and easy-to-use laser optical path length difference detecting device, a laser optical path length difference detecting device, and a coherent optical coupling device. The laser optical path length difference detecting device detects an optical path length difference between propagation paths of a first laser beam (1) and a second laser beam (2), which are mutually coherent when the beams are propagated through two arbitrary optical paths of a plurality of laser beam optical paths. The laser optical path length difference detecting device is provided with an optical path length difference variable means (4) for changing the optical path length difference between the first laser beam (1) and the second laser beam (2), a wavefront inclination generating means (5) for inclining a wavefront of at least one of the first laser beam (1) and the second laser beam (2), and a two-dimensional detector (6) for detecting the interference light intensity distribution of the first laser beam (1) and the second laser beam (2) which have passed through the wavefront inclination generating means.

摘要:
A method and apparatus for selecting paths to route incoming traffic through a data communication network, which is capable of effectively dispersing the traffic load to the selected paths on the network and effectively optimizing the use of network resources. In a communication network, a plurality of label switched paths between an ingress node and an egress node are provided. Incoming traffic at the ingress node is labeled and delivered through the network to the egress node. In a method and apparatus for selecting paths to route the incoming traffic through the network, a plurality of forwarding equivalent class elements (FEC) of the incoming traffic at the ingress node are allocated for the plurality of label switched paths. The labeled traffic is delivered on the plurality of label switched paths on an FEC-element basis so as to route the labeled traffic through the network to the egress node. The traffic load on the respective label switched paths can be effectively dispersed and the sequence of data packets, sent by the same terminal, may be maintained.
摘要:
The rays of light from an object under observation are condensed by objective lens. The incident light from the objective lens is reflected by plane reflector mirror to form a focused image on a detector. The plane reflector mirror floats in at least three reflector mirror floating vessels and even if the telescope tilts, a surface of the fluid in the vessel remains leveled and the plane reflector mirror does not vibrate. Further, the plane reflector mirror includes at least three pads, each of the pads floating in a corresponding reflector mirror floating vessel.

A phase difference detecting device includes a splitter for splitting laser beams into a first group which will travel along a first path and a second group which will travel along a second path, a beam selection/extraction unit for selecting, as reference light, one beam from the first group to allow it to pass therethrough, a path length changing unit for changing the length of the first path, a combining unit for combining the reference light and beams which construct the second group to produce interference light, and a detector for detecting the intensity of the interference light. The device changes the length of the first path using the path length changing unit to detect a path length which maximizes the intensity of the interference light for each of the beams which construct the second group, and determines a phase difference among the beams from the detected path length.
