IDC Re-Engineering Phase 2 Iteration E2 Use Case Realizations

Harris, James M.; Burns, John F.; Hamlet, Benjamin R.; Lober, Randy R.; Vickers, James W.

This architecturally significant use case describes how the System acquires meteorological data to build atmospheric models used in automatic and interactive processing of infrasound data. The System requests the latest available high-resolution global meteorological data from external data centers and puts it into the correct formats for generation of infrasound propagation models. The system moves the meteorological data from Data Acquisition Partition to the Data Processing Partition and stores the meteorological data. The System builds a new atmospheric model based on the meteorological data. This use case is architecturally significant because it describes acquiring meteorological data from various sources and creating dynamic atmospheric transmission model to support the prediction of infrasonic signal detection

US NDC Modernization: Service Oriented Architecture Study Status

Hamlet, Benjamin R.; Encarnacao, Andre V.; Harris, James M.; Young, Christopher J.

This report is a progress update on the USNDC Modernization Service Oriented Architecture (SOA) study describing results from Inception Iteration 1, which occurred between October 2012 and March 2013. The goals during this phase are 1) discovering components of the system that have potential service implementations, 2) identifying applicable SOA patterns for data access, service interfaces, and service orchestration/choreography, and 3) understanding performance tradeoffs for various SOA patterns

US NDC Modernization: Service Oriented Architecture Proof of Concept

Hamlet, Benjamin R.; Encarnacao, Andre V.; Jackson, Keilan R.; Hays, Ian A.; Barron, Nathan E.; Simon, Luke B.; Harris, James M.; Young, Christopher J.

This report is a progress update on the US NDC Modernization Service Oriented Architecture (SOA) study describing results from a proof of concept project completed from May through September 2013. Goals for this proof of concept are 1) gain experience configuring, using, and running an Enterprise Service Bus (ESB), 2) understand the implications of wrapping existing software in standardized interfaces for use as web services, and 3) gather performance metrics for a notional seismic event monitoring pipeline implemented using services with various data access and communication patterns. The proof of concept is a follow on to a previous SOA performance study. Work was performed by four undergraduate summer student interns under the guidance of Sandia staff.

US NDC Modernization Iteration E1 Prototyping Report: Processing Control Framework

Prescott, Ryan M.; Hamlet, Benjamin R.

During the first iteration of the US NDC Modernization Elaboration phase (E1), the SNL US NDC modernization project team developed an initial survey of applicable COTS solutions, and established exploratory prototyping related to the processing control framework in support of system architecture definition. This report summarizes these activities and discusses planned follow-on work.
