A method and a system using the method enabling to decrease required resource for the bandwidth reservation in an inter-site connection network used for communication between communication sites. The aggregation of bandwidth is considered for allocating bandwidth in the inter-site connection network. The network consists of a plurality of nodes each having a packet switch, and a plurality of user sites each constituted by a host or an internal network respectively connected to the plurality of nodes via access lines. With respect to the plurality of user sites, when one user site is to be connected to the other site through the network, a necessary and sufficient bandwidth for interconnecting between the user site and the other is calculated according to the bandwidth of the access line connecting the user site to the network considered as a minimal bandwidth. Based on the calculated result, the bandwidth is allocated to the plurality of nodes.

A small-scale wireless communication system offering advanced security level. An encryption key memory of an access point stores an encryption key list of a plurality of different encryption keys. A change information transmitter periodically transmits change information to a terminal by radio, the change information requesting the change of encryption key. An encryption key selector selects an encryption key from the encryption key list under a rule when the change information transmitter transmits the change information. A terminal-side encryption key memory of the terminal stores a terminal-side encryption key list which is the same as the encryption key list. A change information receiver receives the change information from the access point. Upon reception of the change information, a terminal-side encryption key selector selects an encryption key from the terminal-side encryption key list under a rule which is the same as the rule which the encryption key selector used to select the encryption key.

A thin-film filter which is uniform in thickness and has a smooth surface is provided. A filter forming liquid containing a ultrafine pigment, a photosensitive organic Si compound and a high-boiling polar solvent is coated on a glass substrate to form a filter film, which is subject to light exposure through a mask and then development, to thereby carry out patterning, followed by calcination of the glass substrate, leading to manufacturing of a color filter.

A testing apparatus includes a storage to store a communication log including a communication time and a response confirmation number of packets, and a processing circuit to generate an additional packet having a communication time and a response confirmation number between two consecutive packets having an interval greater than or equal to a threshold value in the communication log. The interval may be an interval of the communication times of or, an interval of the response confirmation numbers of the two consecutive packets. The testing apparatus also includes an interface unit to send the packets stored in the storage and the additional packet to a destination at a time interval based on communication times thereof.

In a moving picture decoding apparatus, a variable-length decoding circuit decodes motion vectors for each macroblock from a bit stream and stores the motion vectors. An error correction circuit calculates a reference vector for an error macroblock using the motion vectors to generate a corrected picture from a reference picture. An inverse-orthogonal transform circuit stores a difference value between direct-current (DC) components after Inverse Discrete Cosine Transform (IDCT) is performed thereon, in the memory for each macroblock. The error correction circuit further calculates a difference value of the DC component of the error macroblock using the difference values of DC components stored in the memory, to add the difference value calculated to the corrected picture generated from the reference picture.

A computer-readable non-transitory recording medium storing therein an information managing program causing a computer to execute extracting from among events that have occurred at objects under management and having dependence relations, combinations of a first event that has occurred at a source-of-dependence object and a second event that has occurred at a dependent object dependent on the source-of-dependence object; judging for each extracted combination, whether a dependence relation exists between the first event and the second event, by using the difference between the time of occurrence of the first event and that of the second event; determining from among the events and based on a judgment result obtained at the judging, an event that has occurred at an object that is a source-of-dependence object but not a dependent object, to be an event to be stored; and storing to a database, information related to the event to be stored.

When a server RM detects a failure in an operating server, a system resource manager selects a substitute server from a pool of a server domain to which a failed server belongs, based on information in a system resource DB, disconnects the failed server from a business network and a storage sub group and moves the failed server to a pool, and permits the substitute server to access a storage group to which the failed server had an access and to connect to the business network to which the failed server was connected, to boot up the substitute server from a SAN.
