Mark Swick presented on two key approaches for architecting radar systems: 1) Create an architecture consistent with the long life cycle of radar systems by using open standards and a data-centric design to enable technical refreshes over time; and 2) Focus domain expertise on areas like algorithms and hardware while using middleware to isolate system software from changes to processors and networks that will inevitably occur throughout the life cycle. The presentation provided background on radar systems and components and discussed how data distribution service (DDS) patterns are well-suited for radar data requirements by providing interoperability, flexibility, and isolation from infrastructure changes.

Repeat Success, Not Mistakes; Use DDS Best Practices to Design Your Complex Distributed Systems
RTI Connext DDS is a powerful tool that lets you efficiently build and integrate complex distributed systems like no other technology – if you use it right. Be aware of how to get the most out of DDS and how to avoid common pitfalls when developing your system. We've developed RTI Connext best practices over the course of hundreds of customer projects and many years. In this webinar, you will learn how to apply the best practices we have developed to use RTI Connext DDS in ways that will enable your system to scale effectively with optimal performance, while avoiding missteps that will cause poor performance, non-determinism and scalability problems.
Communication Patterns Using Data-Centric Publish/SubscribeSumant Tambe
Fundamental to any distributed system are communication patterns: point-to-point, request-reply, transactional queues, and publish-subscribe. Large distributed systems often employ two or more communication patterns. Using a single middleware that supports multiple communication patterns is a very cost-effective way of developing and maintaining large distributed systems. This talk will begin with an introduction of Data Distribution Service (DDS) – an OMG standard – that supports data-centric publish-subscribe communication for real-time distributed systems. DDS separates state management and distribution from application logic and supports discoverable data models. The talk will then describe how RTI Connext Messaging goes beyond vanilla DDS and implements various communication patterns including request-reply, command-response, and guaranteed delivery. You will also learn how these patterns can be combined to create interesting variations when the underlying substrate is as powerful as DDS. We’ll also discuss APIs for creating high-performance applications using the request-reply communication pattern.
This whitepaper focuses on “real-world” systems, that is, systems that interact with the external physical world and must live within the constraints imposed by real-world physics. Good examples include air-traffic control systems, real-time stock trading, command and control (C2) systems, unmanned vehicles, robotic and vetronics, and Supervisory Control and Data Acquisition (SCADA) systems.
More and more these “real-world” systems are integrated using a Data-Centric Publish- Subscribe approach, specifically the programming model defined by the Object Management Group (OMG) Data Distribution Service (DDS) specification.
This whitepaper describes the basic characteristics of real-world systems programming, reasons why DDS is the best standard middleware technology to use to integrate these systems, and a set of “best practices” guidelines that should be applied when using DDS to implement these systems.

DDS in SCADA, Utilities, Smart Grid and Smart CitiesAngelo Corsaro
This presentation introduces the challenges faced by next generation SCADA, Utilities, and Smart-* applications and show how OpenSplice DDS addresses theses. The presentation also showcases the use of OpenSplice DDS in some relevan use cases.
The design of modern Unmanned Aircraft Systems (UAS) includes many safety-critical components, including processors, operating systems, communication infrastructure and application software. The integration of UAS in the National Airspace System (NAS) is starting to put more weight on implementation of safety-certification guidelines such as DO-178, making the design of these systems even more demanding.
The OMG Data Distribution Service (DDS) standard is widely adopted for system integration in Aerospace and Defense. Its high level of decoupling between system components, real-time interfaces and end-to-end support for Quality of Service (QoS) makes DDS well suited for implementation within UAS.
In this webinar, learn how a safety-certifiable implementation of DDS can reduce certification costs of your project by at least $2 million. We will also discuss testability of distributed systems, how to avoid sources of non-determinism, design alternatives to reliable communication, and more. The certification package that makes it all possible will be available soon. As a project manager, system architect or software engineer, learn all about it in this webinar first.
This presentation introduces the key concepts at the foundation of DDS, the data distribution service for real-time systems. Wether you are a new to DDS or a relatively experienced user, you'll find this presentation a good source of information.

To dramatically reduce defense costs, Open Architecture (OA) offers a vision of complex systems of systems built from composable, replaceable modules.
From its origins with the Navy's OA program for ship systems nearly 10 years ago, this design philosophy is spreading to military programs worldwide, including the the Future Architecture Computing Environment (FACE) for avionics, the Unmanned Air Segment Control Segment (UCS) for ground stations, the Army's Common Operating Environment (COE) and the UK's Generic Vehicle Architecture (GVA). These programs are defining technology and acquisition policy for the next generation of defense systems.

The exciting potential of the Industrial Internet of Things (IIoT) is to create bold new intelligent machines and vast distributed systems. The IIoT will change the world across many industries. These applications define the future: renewable energy, cars that drive themselves, planes that fly themselves, smart medical devices, and connected hospitals.
DDS is the standard designed for the Industrial Internet. RTI's Connext communications platform is the leading DDS implementation, proven on real systems representing the breadth of the IIoT.
This webinar will overview some of RTI's real-world applications in the Industrial Internet. Our 750+ projects include applications in Energy (Siemens Wind Power, Toronto Hydro microgrids), Medical (GE Healthcare, BK Medical ultrasound, Harvard-led device connectivity standard), Automotive (Audi, VW), Industrial (Schneider, Joy), and Transportation (Canadian air traffic control, VW, Audi).
Come see why the DDS standard is the communication standard for the Industrial Internet. Based on our leading product and architectural impact, RTI was recently named the #1 most influential company in the Industrial Internet of Things by Appinions as published in Forbes and Reuters.
Speaker: Stan Schneider, CEO of RTI, and a member of the Industrial Internet Steering Committee along with GE, Cisco, Intel, AT&T, IBM, Accenture, and Fujitsu.
Interoperability is a key requirement for the IoT but what does it really mean? Standard protocols for different vendor's devices to interact with each other? Connection between different languages and operating systems? Wireless technology choice? A way for devices to interact with the cloud? Does it include data syntax? Must we model semantics? Can security interoperate? RTI, the world's largest embedded middleware company, participates in about 15 different "interoperability" efforts, including FACE (avionics), GVA (European vehicle architecture), SGIP (smart grid) and ICE (medical systems). We are leaders in the Industrial IoT and its leading consortium, the Industrial Internet Consortium (IIC). This session will examine the depth of the interoperability problem and explore solutions.

Even though the U.S. Department of Defense budget is shrinking and the country's military footprint worldwide is receding the need for the warfighter to have accurate and actionable intelligence has never been more critical. Data from Intelligence, Surveillance, and Reconnaissance (C4ISR) systems such as radar, image processing payloads on Unmanned Aerial Vehicles, and more will be used and fused together to provide commanders with real-time situational awareness. Each system will also need to embrace open architectures and the latest commercial standards to meet the DoD's performance, size, and cost requirements. This e-cast will discuss how embedded defense suppliers are meeting these challenges.
A NEW ARCHITECTURE PROPOSAL TO INTEGRATE OPC UA, DDS & TSN.
Suppliers and end users need a complete solution to address the complexity of future industrial automation systems. These systems require:
• Interoperability to allow devices and independent software applications from multiple suppliers to work together seamlessly
• Extensibility to incorporate future large or intelligent systems
• Performance and flexibility to handle challenging deployments and use cases
• Robustness to guarantee continuity of operation despite partial failures
• Integrity and fine-grained security to protect against cyber attacks
• Widespread support for an industry standard
This document proposes a new technical architecture to build this future. The design combines the best of the OPC Unified Architecture (OPC UA), Data Distribution Service (DDS), and Time-Sensitive Networking (TSN) standards. It will connect the factory floor to the enterprise, sensors to cloud, and real-time devices to work cells. This proposal aims to define and standardize the architecture to unify the industry.

Globus Connect Server Deep Dive - GlobusWorld 2024Globus
We explore the Globus Connect Server (GCS) architecture and experiment with advanced configuration options and use cases. This content is targeted at system administrators who are familiar with GCS and currently operate—or are planning to operate—broader deployments at their institution.
Listen to the keynote address and hear about the latest developments from Rachana Ananthakrishnan and Ian Foster who review the updates to the Globus Platform and Service, and the relevance of Globus to the scientific community as an automation platform to accelerate scientific discovery.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

The U.S. Geological Survey (USGS) has made substantial investments in meeting evolving scientific, technical, and policy driven demands on storing, managing, and delivering data. As these demands continue to grow in complexity and scale, the USGS must continue to explore innovative solutions to improve its management, curation, sharing, delivering, and preservation approaches for large-scale research data. Supporting these needs, the USGS has partnered with the University of Chicago-Globus to research and develop advanced repository components and workflows leveraging its current investment in Globus. The primary outcome of this partnership includes the development of a prototype enterprise repository, driven by USGS Data Release requirements, through exploration and implementation of the entire suite of the Globus platform offerings, including Globus Flow, Globus Auth, Globus Transfer, and Globus Search. This presentation will provide insights into this research partnership, introduce the unique requirements and challenges being addressed and provide relevant project progress.

Editor's Notes
Interoperability and Open Architecture
Current practice but…
What is it really?
Why is it hard?
This illustration was originally created by the U.S. Navy, who chose NDDS for its Open Architecture Computing Environment. Of all the software, only NDDS covers the full range of performance requirements from non-real-time to extreme real-time.
Non-real time: business layer apps
Soft real time: C2, display & decision support
Hard real time: e.g. sensor & weapon control
Extreme real-time: e.g. signal processing
A data-centric integration solution to achieve semantic interoperability is important and achievable.
It is important because… One of the only things I can guarantee in a SOS is that it will change. At some point, it will. And when that change happens, rather than have your system be broken by it, why not survive it? If I architect my data in a rigorous and formal manner, and since data is what the systems operate on, then any changes in the system are easily accommodated, because they’d manifest as changes to the information present in the SOS. If the changes are made in a rigorous and repeatable way, then by knowing the rules for formation and the abstract data model that all things in the SOS come from, I can simply transform it and understand it if need be. The data will have meaning. It will have context. It will be usable and understood.
Letting your system be broken by something that is inevitable seems a bit silly, especially since we can anticipate that change and accommodate it by making some intelligent architecture and design decisions upfront.
Here we can see legacy, future and current systems – which is a reality – they can technically interoperate via a protocol using a common infrastructure. We know how to do that. They can syntactically interoperate by using a common data structure. But how do we accommodate the systems where can can’t change the interfaces? When they are incompatible? We need a mediation component. Achieving semantic interoperability relies on components such as this, especially since one of our requirements was that we needed to be able to accommodate change and not be broken by it (have to make changes to existing interfaces).
The TSS includes a mapping of the TS API to DDS, per the FACE Technical Standard.
Standard and open interfaces:
TS API
RTI Transport API (called NETIO)
DDS-RTPS wire protocol
FACE OS security profile
Internally DDS API
A model is anything used in any way to represent something else. We use models to observe the effect on manipulating the original, without actually having to manipulate it. A really good model will capture all of the details we need to manipulate the original, and no more.
On the left we have a picture of an actual 1967 ford mustang gt, and on the right a model of that same car. Let’s say you have a child that is going through a phase where they’re really into cars. And this child wants nothing more than what his dad has – a 1967 ford mustang gt. Now, I love my kids and I want to give them everything just so I could see what marvelous things they’d do with it. However, I am not about to hand over the key to a car to my toddler. I would give them a scaled, fit for purpose version, such as the model toy on the right. It has very little in the way of extras, but it is entirely sufficient AND safe to entertain my toddler.
A data model is a representation that describes the data about the things that exist in your domain.
If you have a system – since systems operate on data – well, then you have a data model. If you’re a system integrator, you deal with data models during your integration activities. Data models come in many different representations, they express many different things in varying degrees of explicitness. Some data models capture information very unambiguously and others don’t. But no matter where your data model falls on the spectrum, you can work with it to make it better.
Data models come in many flavors, and they’re not all equal. Which is best for you is going to depend on your systems requirements, and the function of the system, or component that will use that data. Here we have three examples of models many people have some familiarity with at least two of them.
The dictionary is a list of terms for a particular domain of knowledge. It contains a list of terms, as well as the definitions and pronunciations for those terms. Using a representation such as this, words alongside their meaning, we can communicate about the things that exist in our domain and the meaning of those expressions, the words, is understood to those who use the same dictionary.
The linnean taxonomy is an example of a hierarchical data model - it shows us the conception, naming, and classification of organism groups. It represents information in a hierarchical format, such a classification or categorization schema. Using a representation structure such as this, I can express that “this” is one of “those”.
The last example is the periodic table of elements. From this we can tell that Gold has a weight and a certain number of protons… but I don’t know if 2 elements will bond, and if they will what they will form, simply by looking at this table.
Per our requirements, we define a good data model to be one that captures, among other things, the semantics, or meaning, of the things that is represents in an unambiguous way.
The process by which you generate a data model is something you need to consider… Especially if you need that data model that helps you meet your key non-functional requirements.
