In order to meet the real communication situation of the train, we make data request for train handover to test the network communication performance.
The data were requested for the time period 2000 2005; however, if data were only available for part of the study period, responses were still included in the study.
Rtr7 represents the server; Rtr1, Rtr2, Rtr3, Rtr4, Rtr5, and Rtr6 represent NDN routers; Src1, Src2, Src3, Src4, Src5, Src6, Src7, Src8, and Src9 represent data requests for the high-speed train in NDN-GSM-R, namely, the data applicants; and Dst1, Dst2, Dst3, Dst4, Dst5, Dst6, Dst7, Dst8, and Dst9 represent data which are provided for the high-speed train in NDN-GSM-R, namely, the data providers.
Data were requested for the research group and the Regional Health Departments transferred them with the corresponding permission to use in the Grupo de Investigación en Utilización de Medicamentos en el Sistema Nacional de Salud (Drug Utilization in the Spanish National Health System Research Group) projects.
The data request for this study specified routinely collected data to prevent specific data retrieval from the Patient Administration System (PAS).
These data will be requested for the patients included in the study.
However, it may prove difficult to validate particular methods prior to access being granted to the data requested, particularly for DE searching for unforeseen correlations across aggregated datasets.
There were 1480 responses that included the full data requested (provided the data were available) for 1732 requests made, representing a response rate of 86%.
A guard to ensure that the classification of the data items requested for access matches the consumer's security clearance (sys. req. 9): begin{aligned} {mathbf{grd7:}}&quad security_clearance {consumer} = classified {data_items} end{aligned}.
