Abstract:
Provided herein a method and apparatus for determining a QoS (quality of service) profile in the data distribution service, the method including determining network environment information; and determining the QoSProfile based on the network environment information, wherein the QoSProfile includes a QoSFunction, QoSMatching, QoSStatement, QoSConstraint, and QoSCharacteristic.
Abstract:
A communication connecting method between nodes through a network, includes: storing communication connection information acquired through searching for communication entities of other nodes; determining whether communication connection information on a communication entity of a connection target node exists by searching for the stored communication connection information; and configuring communication connection with the communication entity of the connection target node based on the determination result.
Abstract:
Provided herein is a method and apparatus for generating a virtual object for DDS (Data Distribution Service) communication in multiple network domains, the apparatus including: a communicator for receiving EDP (Endpoint Discovery Protocol) information on a remote Endpoint from a remote network domain separated physically or logically; and a virtual object generator for matching the EDP information on the remote Endpoint and information included in the remote network domain prestored in a database, and for generating a virtual object corresponding to the remote Endpoint.
Abstract:
An apparatus for monitoring a data distribution service (DDS), and a method thereof are disclosed. A DDS monitoring apparatus monitoring a data distribution service (DDS) includes: a monitoring participant configured to receive a monitoring topic from a DDS node, wherein the monitoring topic is status information of the DDS node; a monitoring data collector configured to collect the monitoring topic, and to determine whether or not the monitoring topic is urgent; and a monitoring data analyzer configured to analyze the monitoring topic according to whether or not the monitoring topic is urgent to determine whether to create DDS status information corresponding to the status of the DDS node. Accordingly, it is possible to monitor a DDS in real time.
Abstract:
A gateway for interconnection of heterogeneous middleware includes a high level architecture (HLA) federate; a data distribution service (DDS) participant; a clock federate for a wall clock; and a time manger configured to synchronize times of the HLA federate and the DDS participant to the wall clock provided by the clock federate.
Abstract:
Disclosed is an apparatus for modeling of a hybrid system and the apparatus includes: a model configuring unit modeling ports, structures, and constraints for one or more cyber physical systems implemented in the hybrid system and constituting a core model including a port model, a structure model, and a constraint model constituted for each cyber physical system; and a model setting unit setting a connection relationship of the port model, the structure model, and the constraint model for each core model and defining a discrete component and a continuous component for each model.
Abstract:
Provided are a method for updating a system and a system thereof that can simultaneously update a new-version application program and a device driver without interruption or restarting of the system which is developed and operating.
Abstract:
Disclosed are a computing apparatus for providing an entity search means so as to perform data communication between different entities of a Data Distribution Service (DDS) in a multi-network domain environment, and a method of operating the same. A method of operating a computing system for a Data Distribution Service (DDS) service in a DDS system including a first network domain and a second network domain includes: searching for search information of DDS entities included in the first network domain; determining at least a DDS entity among the DDS entities as a representative entity of the first network domain; and providing the search information of the DDS entities to a representative entity of the second network domain through the representative entity of the first network domain.
Abstract:
Provided herein a method and apparatus for generating a data distribution service application, the method including syntax-analyzing an IDL (interface description language) file; determining a topic model to be used in the data distribution service application based on a result of the syntax-analyzing of an IDL (interface description language) file; receiving QoS information and determining a QoS model by a QoS (quality of service) modeler; determining a DDS application model based on the topic model and QoS model by a DDS (data distribution service) application modeler; and generating a source code based on the topic model, QoS model and DDS application model.
Abstract:
Disclosed is a modularizing apparatus modularizing a function module in DDS middleware, including: a DCPS module providing an interface with an application program; and a library module initializing and creating the function module, classifying the created function module for each function and storing the classified function module, and providing a function module corresponding to a request by the DCPS module to the DCPS module.
