An optical multi-drop path is set to a downstream direction, an optical path between adjacent nodes is set to a upstream direction, a packet sorting unit is provided for appropriately controlling packet streams in the downstream direction and upstream direction, and one-to-one or one-to-N communication can be performed not only between servers and clients but also between the clients even when a multi-drop transmission is used in the downstream direction.

In a network wherein a data plane for communicating user data, and a control plane for managing data forwarders are configured of different media, the path teardown of the data plane which is forwarding the data is prevented when a fault has occurred in only the control plane. When the GMPLS controller of the control plane has detected refresh timeout with respect to an adjacent node (101 in FIG. 1), it checks whether or not a transmission equipment corresponding to a faulty controller has a fault (102), and it maintains a path state (103) in a case where the fault is limited to the control plane. Thus, the exchange of refresh messages with the adjacent node is continued without cleaning up the resources of the transmission equipment (104 through 107).

An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.

The proxy server notifies a client of the entry information instead of the server and includes means for obtaining from the server entry information used for accessing a function that the server can supply to the client according to the request from the client. The proxy server also includes means for creating entry information used for accessing a function enabled for the client to use, with reference to the obtained entry information. Also, the proxy server includes means for notifying the client of the created entry information. The proxy server may contain some functions that can be independently supplied to the client without involving the server.
摘要:
A method or system to change a display output by a program without modifying the program. The invention also provides a program or computer to accomplish this change in display output. The invention intercepts and converts a graphics display command into the desired configuration and also performs reverse conversion of input data in compliance with computer environment assumed from the program. Additionally the invention converts data exchanged between the program and computer system mutually as needed.

Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.

A method of help-information control for displaying help information on a display unit of an information processing system executing a plurality of application programs. A status management table for storing the executing status of application programs is provided as common to these programs. During execution of a given application program, the contents of the status information table are updated successively in accordance with the executing status. Whenever an operator makes a help request, the contents of the status management table in effect at that point in time are referenced. The table is searched for the help information corresponding to the request. When found and retrieved, the information is displayed. The search is performed using a program identifier, a message identifier, and a help message searching table that includes the position information containing the corresponding help data. Each application program is equipped with a control data part that makes it possible to reference help data of other application programs.
摘要:
Power consumption on GMPLS controlled networks can be reduced by cutting power consumption on spare paths that are not normally used. To achieve power consumption reduction, in the path setting process, a path is calculated while taking the power saving capability of each interface into account, and the applicable interface is set to the power-saving state when setting the spare path. When the spare path was set to the operating state, then the power-saving state on the applicable interface was canceled so that interface could operate normally.
