Abstract:
Disclosed are a computer-readable recording medium which records communication programs, communication method and communication apparatus capable of easily performing selection and execution of communication units according to communication units of communication partners. A profile management unit manages specific information including a combination of device type information and user identification information in each communication unit, and user IDs associated with the combined information. An application controller, when a session using any one of communication units is established between users, refers to specific information and associates user IDs with the combined information in the communication unit. A collection unit collects presence information where state information indicating whether communication units are available is associated with the combined information in each communication unit. A presence management unit, when a user ID is specified, refers to presence information and reports presence information to client terminals of users where the session is established.
Abstract:
When a service apparatus receives a service request from a client apparatus, the service apparatus determines an access propriety based on whether the client apparatus is already registered in a list. If the client apparatus is not registered, the service apparatus acquires meta-information of the client apparatus in question and also other apparatuses. The service apparatus then determines an approving apparatus among the apparatuses based on the acquired meta-information. The approving apparatus is made to display the meta-information of the client apparatus in question and requests an approver to judge propriety of service provision.

Abstract:
In a delay time measuring apparatus a sequence number, data length, and receiving time of a data packet transmitted from a source unit to a destination unit are stored in a storage section. In addition, an ACK number and receiving time of an ACK packet returned from the destination unit to the source unit are stored in the storage section. After that, a calculation section obtains an ACK packet an ACK number of which is equal to a value obtained by adding data length of a second data packet of two successive data packets transmitted without waiting for the ACK packet to a sequence number of the second data packet of the two successive data packets from the storage section. Then the calculation section calculates round trip time from receiving time of the second data packet of the two successive data packets and receiving time of the ACK packet obtained.
Abstract:
A capacitor includes a dielectric substrate and a large number of filamentous conductors formed to penetrate through the dielectric substrate in a thickness direction thereof. An electrode is connected to only respective one ends of a plurality of filamentous conductors constituting one of groups each composed of a plurality of filamentous conductors.
