Abstract: In a transaction management system which is a distributed ledger system in which a business network is formed of a plurality of nodes, the node calculates an upper limit of the number of transactions that can be issued by each of a plurality of organizations according to a calculation rule shared among the nodes, and refuses to accept the transaction from an organization of the organizations of which the number of transactions in past exceeds the upper limit of the number of transactions.

Abstract: It is made possible to realize bidirectional communication safely on the cloud side, and on-premises side in a job execution system. It is checked whether or not there is an agent with the same logical name at time of agent registration. In a case that there is the same logical name, transfer performance required of each agent is checked, and communication is performed by rewriting a logical name during transfer by using an existing logical name for an agent required of the highest transfer performance, and using a logical name which is a new unique alias for the other agent.

Abstract: An injector failure diagnostic device 1 diagnoses injector failures for a multi-cylinder internal combustion engine 2 having injectors 21 to 24, each injector injects fuel to the corresponding cylinder. The injector failure diagnostic device 1 includes: an operating sound obtainment unit 12 configured to obtain current operating sound that is operating sound when all of the injectors operate, and obtain pseudo-failure operating sound sequentially for each of the injectors, the pseudo-failure sound being operating sound generated by stopping the fuel injection from one injector while maintaining the operation of the remaining injectors; and a faulty injector identification unit 13 configured to determine whether or not the pseudo-failure operating sound of each injector obtained by the operating sound obtainment unit 12 is similar to the current operating sound to identify a faulty injector.

Abstract: The data center (DC) linking system provides a line under specified communication conditions to each tenant, wherein in each DC, a virtual network identifier (i) and/or (ii) serving as a communication type identifier which separates communications of each tenant of each of a plurality of DCs and a virtual network identifier (iii) which is provided by a carrier and serves as a line identifier which separates a plurality of communications having different communication conditions are identified and managed in association with each other; and the communications of each tenant are identified on the basis of the communication type identifier. Any one line identifier for allocating a line having a communication condition desired by a tenant is assigned to each communication identified on the basis of communication content in a transmitting side DC.

Abstract: In a traffic information collection system in which a collection node collecting collection information regarding traffic acquired by nodes on a network identifies a collection point of the collection information, a transmission node to transmit the collection information from a designated transmission port and a collection control node are included. The collection control node manages a connection relation of the transmission port of the transmission node and a reception IF of the collection node. The collection control node determines the reception IF of the collection node receiving the collection information acquired at a designated collection point of any node. The collection control node designates the transmission port connected to the determined reception IF with respect to the transmission node and outputs the collection information from the designated transmission port. The collection control node informs the collection node of correspondence information of the collection point and the reception IF.

Abstract: A congestion control system is provided between a terminal and a server device to avoid a congestion state in the server device by preferentially regulating the request with a high load on the server device. The congestion control system estimates the load of the request from the terminal to be placed on the server device for the next communication sequence, based on the response from the server device to the request from the terminal, and adds the estimated load information to the response to the terminal. Subsequently, the request from the terminal includes the load information, so that the congestion control system controls the regulation of the request from the terminal based on the load information included in the request.

Abstract: A relay apparatus adds a program location indicating a source of a correction program, to a response from a server requested of to acquire contents by the client, and transmits a response to the client. The program location contains tags identifying a response transmitting server and the relay apparatus as parameters. Upon receiving the response from the server via the relay apparatus, the client transmits a correction program acquisition request containing the parameters to a destination (management server) indicated by the program location. Upon receiving the request, the management server generates a correction program which rewrites a contents link, based on the parameters included in the request and transmits it to the client as a response. The client rewrites a contents link destination on the basis of the acquired correction program.

Abstract: When communication traffic between communication devices is shaped by a relay device on a network, the communication speed of a transport layer is prevented from being dramatically reduced as compared to the shaped traffic on a network with a high error rate. On the basis of the SID of data received from a communication device and a data size, a relay device predicts the SID expected to be received for the next time in the same communication, compares the predicted SID with another SID included in data received for the next time, and releases the shaped traffic for the data if the received SID is smaller than the predicted SID. Further, when consecutively receiving a given number or larger of pieces of data which are larger than the predicted SID, the relay device releases the shaped traffic for the data.

Abstract: To inform a terminal whether linked URLs contained in a browsed Web page are subject to browsing restriction, without placing a high load on a URL information database, a relay apparatus acquires a Web page from a Web server in accordance with a request from a terminal, queries a URL database as to a linked URL contained in the Web page, creates link information containing a restriction level to which a linked Web page belongs and the in-page location of a link display, determines a link subject to browsing restriction based on the link information and a predetermined restriction level of the requesting terminal, changes the link display, and sends the Web page with the changed link display to the terminal. Further, the relay apparatus caches the link information. If link information about a Web page acquired in accordance with a request from the terminal exists in a cache, the relay apparatus does not query URL information but uses the link information.

Abstract: The present invention provides an e-mail-based chat system that is available from a terminal without a push architecture and can be used with an existing server. The invention relates to a relay apparatus to be installed on communication lines between terminals and servers consisting of a transmission server and a retrieval server. The relay apparatus puts on hold data retrieval requests received from the terminals without relaying the data retrieval requests to the retrieval server and withholds responses to the terminals. When the relay apparatus receives chat message data from a terminal, it relays the data to the transmission server. Right after the relaying of the data, the relay apparatus acquires the data from the transmission server via the retrieval server and creates response data from the acquired data, thus responding to the data retrieval requests on hold with the response data.
