The Data Distribution Service for Real-Time Systems (DDS) is an Object Management Group (OMG) standard for publish/subscribe designed to address the needs of a large class of mission- and business-critical distributed real-time systems and system of systems. The DDS standard was formally adopted in 2004 and in less than five years from its inception has experienced swift adoption in a wide variety of application domains. These application domains are characterized by the need to distribute high volumes of data with predictable low latencies, such as, Radar Processors, Flying and Land Drones, Combat Management Systems, Air Traffic Management, High Performance Telemetry, Large Scale Supervisory Systems, and Automated Stocks and Options Trading. Along with wide commercial adoption, the DDS Standard has been recommended and mandated as the technology for real-time data distribution by key administrations worldwide such as the US Navy, the DoD Information-Technology Standards Registry (DISR), the UK MoD, and EUROCONTROL.
This two-part Tutorial will cover most of the key aspects of DDS to ensure that you can proficiently start using it for designing or developing your next system. In brief this tutorial will get you jump-started into DDS.
The Data Distribution Service (DDS) is a standard for efficient and ubiquitous data sharing built upon the concept of a, strongly typed, distributed data space. The ability to scale from resource constrained embedded systems to ultra-large scale distributed systems, has made DDS the technology of choice for applications, such as, Power Generation, Large Scale SCADA, Air Traffic Control and Management, Smart Cities, Smart Grids, Vehicles, Medical Devices, Simulation, Aerospace, Defense and Financial Trading.
This two part webcast provides an in depth introduction to DDS ā the universal data sharing technology. Specifically, we will introduce (1) the DDS conceptual model and data-centric design, (2) DDS data modeling fundamentals, (3) the complete set of C++ and Java API, (4) the most important programming, data modeling and QoS Idioms, and (5) the integration between DDS and web applications.
After attending this webcast you will understand how to exploit DDS architectural features when designing your next system, how to write idiomatic DDS applications in C++ and Java and what are the fundamental patterns that you should adopt in your applications.
Introduced in 2004, the Data Distribution Service (DDS) has been steadily growing in popularity and adoption. Today, DDS is at the heart of a large number of mission and business critical systems, such as, Air Traffic Control and Management, Train Control Systems, Energy Production Systems, Medical Devices, Autonomous Vehicles, Smart Cities and NASAās Kennedy Space Centre Launch System.
Considered the technological trends toward data-centricity and the rate of adoption, tomorrow, DDS will be at the at the heart of an incredible number of Industrial IoT systems.
To help you become an expert in DDS and exploit your skills in the growing DDS market, we have designed the DDS in Action webcast series. This series is a learning journey through which you will (1) discover the essence of DDS, (2) understand how to effectively exploit DDS to architect and program distributed applications that perform and scale, (3) learn the key DDS programming idioms and architectural patterns, (4) understand how to characterise DDS performances and configure for optimal latency/throughput, (5) grow your system to Internet scale, and (6) secure you DDS system.

DDS is a very powerful technology built around a few simple and orthogonal concepts. If you understand the core concepts then you can really quickly get up to speed and start exploiting all of its power. On the other hand, if you havenāt grasped the key abstractions you might not be able to exploit all the benefits that DDS can bring.
This presentation provides you with an introduction to the core DDS concepts and illustrates how to program DDS applications. The new C++ and Java API will be explained and used throughout the webcast for coding examples thus giving you a chance to learn the new API from one of the main authors!
The DDS specification provides fine-grained control over the real-time behaviour, dependability, and performance of DDS applications by means of a rich set of QoS Policies. The challenge for many DDS users is that the specifications explains very clearly how each QoS allows to control very specific aspects of data distribution yet it provides no hints on how different QoS should be composed to control complex properties such as the consistency model, or to impose end-to-end real-time scheduling decision. This half-day tutorial will fill this gap by providing attendees with (1) an explanation of how the various QoS compose, and (2) providing attendees with a series of QoS-composition Patters that can be used to control macro-properties of an application, such as the consistency model.

DDS Advanced Tutorial - OMG June 2013 Berlin MeetingJaime Martin Losa
Ā
An extended, in-depth tutorial explaining how to fully exploit the standard's unique communication capabilities.Presented at the OMG June 2013 Berlin Meeting.
Users upgrading to DDS from a homegrown solution or a legacy-messaging infrastructure often limit themselves to using its most basic publish-subscribe features. This allows applications to take advantage of reliable multicast and other performance and scalability features of the DDS wire protocol, as well as the enhanced robustness of the DDS peer-to-peer architecture. However, applications that do not use DDS's data-centricity do not take advantage of many of its QoS-related, scalability and availability features, such as the KeepLast History Cache, Instance Ownership and Deadline Monitoring. As a consequence some developers duplicate these features in custom application code, resulting in increased costs, lower performance, and compromised portability and interoperability.
This tutorial will formally define the data-centric publish-subscribe model as specified in the OMG DDS specification and define a set of best-practice guidelines and patterns for the design and implementation of systems based on DDS.
The Data Distribution Service (DDS) is a standard for ubiquitous, interoperable, secure, platform independent, and real-time data sharing across network connected devices. DDS is today used in a large class of applications, such as, Power Generation, Large Scale SCADA, Air Traffic Control and Management, Smart Cities, Smart Grids, Vehicles, Medical Devices, Simulation, Aerospace, Defense and Financial Trading.
Differently from traditional message-centric technologies, DDS is data-centric ā the accent is on seamless (user-defined) data sharing as opposed to message delivery. Therefore, when embracing DDS and data-centricity, data modeling becomes a key step in the design of a distributed system.
This webcast will (1) explain the role and scope of data modeling in DDS, (2) introduce the techniques at the foundation of effective and extensible Data Models, and (3) summarize the most common DDS Data Modeling Idioms.
Making the right data available at the right time, at the right place, securely, efficiently, whilst promoting interoperability, is a key need for virtually any IoT application. After all, IoT is about leveraging access data ā that used to be unavailable ā in order to improve the ability to react, manage, predict and preserve a cyber-physical system.
The Data Distribution Service (DDS) is a standard for interoperable, secure, and efficient data sharing, used at the foundation of some of the most challenging Consumer and Industrial IoT applications, such as Smart Cities, Autonomous Vehicles, Smart Grids, Smart Farming, Home Automation and Connected Medical Devices.

Multiple protocols have been positioned as ātheā application-layer messaging protocol for the Internet of Things (IoT) and Machine-to-Machine (M2M) communication. In fact, these protocols address different aspects of IoT messaging and are complementary more than competitive (other than for mindshare). This presentation compares two of these protocols, MQTT and DDS, and shows how they are designed and optimized for different communication requirements.
RUSTing is not a tutorial on the Rust programming language.
I decided to create the RUSTing series as a way to document and share programming idioms and techniques.
From time to time Iāll draw parallels with Haskell and Scala, having some familiarity with one of them is useful but not indispensable.
The OMG DDS (Data Distribution Service) is a standard for data
distribution which is widely used as the foundation for operational
systems such as air traffic control and management, combat systems,
distributed telemetry and control, etc. On the other hand, HLA (High
Level Architecture) is a communication and coordination standard which
is widely adopted in the distributed simulation community.
DDS is increasingly gaining adoption in distributed simulation,
especially for those systems that require high throughput, low
latencies and scalability. In addition, the use of DDS in simulation
provides native interoperability between operational and simulated
systems, thus eliminating integration overhead and complexities.
This presentation introduces DDS and HLA, provide an apple-to-apple
comparison between the two standards and show how DDS and HLA systems
can be seamlessly integrated together.
OpenSplice DDS enables seamless, timely, scalable and dependable data sharing between distributed applications and network-connected devices. Its technical and operational benefits have propelled adoption across multiple industries, such as Defence and Aerospace, SCADA, Gaming, Cloud Computing, Automotive, etc.
If you want to learn about OpenSplice DDS or discover some of its advanced features, this webcast is for you!
In this two-parts webcast we will cover all the aspects tied to architecting and developing OpenSplice DDS systems. We will look into Quality of Services, data selectors concurrency and scalability concerns.
We will present the brand-new, and recently finalized, C++ and Java APIs for DDS, including examples of how this can be used with C++11 features. We will show how, increasingly popular, functional languages such as Scala can be used to efficiently and elegantly exploit the massive HW parallelism provided by modern multi-core processors.
Finally we will present some OpenSplice specific extensions for dealing very high-volumes of data ā meaning several millions of messages per seconds.
This presentations explains the foundations of Stream Processing and shows how elegant Stream Processing Architectures can be built by using in synergy DDS and CEP.
This presentation introduced Vortex by means of a running example. Throughout the presentation we will show how Vortex makes it easy to build a micro-blogging platform a la Twitter.
Vortex is a platform that provides seamless, ubiquitous, efficient and timely data sharing across mobile, embedded, desktop, cloud and web applications. Today Vortex is the enabling technology at the core the most innovative Internet of Things and Industrial Internet applications, such as Smart Cities, Smart Grids, and Smart Traffic.
This two parts tutorial (1) introduces the key concepts of Vortex, (2) gets you started with using Vortex to efficiently exchange data across mobile, embedded, desktop, cloud and web applications, and (3) provides a series of best practices, patterns and idiom to get the best our of Vortex.
The only prerequisite to fully exploit this tutorial is a basic understanding of Java, C++ and JavaScript. Some knowledge of Scala and CoffeScript will be a plus.
Building Real-Time Web Applications with Vortex-WebAngelo Corsaro
Ā
The Real-Time Web is rapidly growing and as a consequence an increasing number of applications require soft-real time interactions with the server-side as well as with peer web applications. In addition, real-time web technologies are experiencing swift adoption in traditional systems as a means of providing portable and ubiquitously accessible thin client applications.
In spite of this trend, few high level communication frameworks exist that allow efficient and timely data exchange between web applications as well as with the server-side and the back-end system. Vortex Web is one of the first technologies to bring the powerful OMG Data Distribution Service (DDS) abstractions to the world of HTML5 / JavaScript applications. With Vortex Web, HTML5 / JavaScript applications can seamlessly and efficiently share data in a timely manner amongst themselves as well as with any other kind of device or system that supports the standard DDS Interoperability wire protocol (DDSI).
This presentation will (1) introduce the key abstractions provided by Vortex Web, (2) provide an overview of its architecture and explain how Vortex Web uses Web Sockets and Web Workers to provide low latency and high throughput, and (3) get you started developing real-time web applications.

Connected Mobile and Web Applications with VortexAngelo Corsaro
Ā
The widespread availability of high-end mobile devices such as smart-phones, tablets and phablets, along with the availability of browser enabled devices, has imposed these platforms as one of the main target for user interfaces. As a result mobile and web applications need now to be easily āconnectedāto the rest of the system.
This presentations will (1) showcase how the the Vortex Data Sharing Platform can be effectively and productively used to create connected mobile and web-applications, (2) take you through the steps required to use Vortex in mobile and web applications.
Reactive architectures are emerging as the way to build systems that are responsive, scalable, resilient and event-driven. In other terms, systems that deliver highly responsive user experiences with a real-time feel, that are scalable, resilient, and ready to be deployed on multicore and cloud computing architectures. The Reactive Manifesto (see http://www.reactivemanifesto.org/) captures the key traits that characterize reactive architectures.
The Data Distribution Service (DDS) incarnates the principles enumerated by the reactive manifesto and provides a very good platform for building reactive systems. In this webcast I will (1) introduce the key principles of Reactive Architectures, (2) explain the DDS features that are essential to build reactive systems, and (3) introduce some programming techniques that remove inversion of control while maintaining applications even-driven.
This presentation introduces the coordination model at the foundation of Vortex and explains its foundational concepts and features. Then it provides an overview of the various technological element that implement the model and how they are deployed in IoT applications such as connected vehicles, smart cities, smart grids and connected medical devices.
Vortex Lite brings DDS connectivity to resource constrained embedded systems. As a a first class citizen of the Vortex platform it can be used for peer-to-peer fog/edge computing between embedded devices as well as gateways and well as for very efficient device to cloud data sharing. Vortex Lite has been designed with efficiency and portability in mind. This makes it the fastest DDS implementation on the market on enterprise grade hardware and the most lightweight on embedded targets. Likewise its architecture structurally facilitates porting across computing and networking stacks.
This presentation introduces Vortex Lite , provides an overview of its architecture, its design choices as well as report about its performance. The webcast will also explain the role played by Lite within the Vortex family and how it can be used for both device-to-device (fog/edge computing) as well as device-to-cloud.
Middleware technologies today play a key role in the vast majority of mission- and business-critical systems. Choosing the right middleware infrastructure for these systems is a non-trivial task that must take into account many different dimensions ranging from the purely technical to tactical and strategic aspects. This Webcast will compare and contrast the Data Distribution Service for Real-Time Systems (DDS) against the Advanced Message Queuing Protocol (AMQP). The comparison will provide an in depth analysis of the technical differences between the two standards and will detail their technology management and technology strategy standpoints.
The OMG has recently standardized a UML Profile for DDS. This brief tutorial, which was presented at the OMG RTWS 2009, provides you with an introduction to the standard.

The OMG Data Distribution Service (DDS) has brought a disruptive wave of innovation into what is commonly referred to as āMessagingā technology. DDS raises the abstraction level from unstructured, or loosely structured, messages to sound data types that allow architects and application developers to deal with concepts close to their problem space as opposed to having to worry about āplumbingā -- as it happens as with many messaging technologies. As it is common for disruptive innovations to take some time to be digested, many people still see DDS as an ultra-fast real-time messaging -- yet this is only the tip of the iceberg.
This presentation will explain how Data Distribution is different from Messaging and as a result how DDS differs from messaging technologies such as JMS. The webcast will cover the architectural benefits brought by data centricity as well as how the features introduced by the recently adopted DDS specification on Dynamic and Extensible Topic Types will support the design of efficient, extensible and evolvable systems.
Presentation of the DDS Interoperability demo performed in Washington DC between RTI, TwinOaks and PrismTech.
This demonstration shows the use of the DDS-RTPS interoperability protocol in 9 different scenarios.
The OMG DDS standard has recently received an incredible level of attention and press coverage due to its relevance for Consumer and Industrial IoT applications and its adoption as part of the Industrial Internet Consortium Reference Architecture. The main reason for the excitement in DDS stems from its data-centricity, efficiency, Internet-wide scalability, high-availability and configurability.
Although DDS provides a very feature rich platform for architecting distributed systems, it focuses on doing one thing well ā namely data-sharing. As such it does not provide first-class support for abstractions such as distributed mutual exclusion, distributed barriers, leader election, consensus, atomic multicast, distributed queues, etc.
As a result, many architects tend to devise by themselves ā assuming the DDS primitives as a foundation ā the (hopefully correct) algorithms for classical problems such as fault-detection, leader election, consensus, distributed mutual exclusion, distributed barriers, atomic multicast, distributed queues, etc.
This Webcast explores DDS-based distributed algorithms for many classical, yet fundamental, problems in distributed systems. By attending the webcast you will learn how recurring problems arising in the design of distributed systems can be addressed using algorithm that are correct and perform well.
SimD is a safe, productive and efficient C++ API for the OMG DDS. This presentation introduces the basic concepts of SimD and guides you through the steps required to write your first SimD application.

Ā An increasing number of Software Architects realise that data is the most important asset of a system and start embracing the Data-Centric revolution (datacentricmanifesto.org) - setting data at the centre of their architecture and modelling applications as "visitors" to the data. At the same time, architects have also realised how reactive architectures (reactivemanifesto.org) facilitate the design of scalable, fault-tolerant and high performance systems.Ā Few architects have yet realised how reactive and data-centric architectures are two sides of the same coin and as such should always go together.Ā This presentation explains why reactive data-centric architecture is the future and how the OMG DDS Standard is uniquely positioned to support this paradigm shift. A series of case studies will highlight how the data-centric revolution is being applied in practice and what measurable benefits it is providing.
This was the opening presentation of the Zenoh Summit in June 2022. The presentation goes through the motivations that lead to the design of the zenoh protocol and provides an introduction of its core concepts. This is the place to start to understand why you should care about zenoh and the way in which is disrupts existing technologies.

Zenoh is rapidly growing Eclipse project that unifies data in motion, data at rest and computations. It elegantly blends traditional pub/sub with geo distributed storage, queries and computations, while retaining a level of time and space efficiency that is well beyond any of the mainstream stacks. This presentation will provide an introduction to Eclipse Zenoh along with a crisp explanation of the challenges that motivated the creation of this project. We will go through a series of real-world use cases that demonstrate the advantages brought by Zenoh in enabling and optimising typical edge scenarios and in simplifying the development of any scale distributed applications.

Fog computing aims at providing horizontal, system-level, abstractions to distribute computing, storage, control and networking functions closer to the user along a cloud-to-thing continuum. Whilst fog computing is increasingly recognised as the key paradigm at the foundation of Consumer and Industrial Internet of Things (IoT), most of the initiatives on fog computing focus on extending cloud infrastructure. As a consequence, these infrastructure fall short in addressing heterogeneity and resource constraints characteristics of fog computing environments.
fogā5 (read as fog O-five or fog OS) is an Eclipse IoT Project that is building a fog computing infrastructure from first principle. In other terms, fogā5 has been designed to address the challenges induced by fog computing in terms of heterogeneity, decentralisation, resource constraints, geographical scale and security.
This webcast will introduce fogā5, motivate its architecture and building blocks as well as provide a demonstration of fogā5 provisioning applications that span from the cloud to the things.
The video recording for this presentation is available at https://www.youtube.com/watch?v=Osl3O5DxHF8
Fog Computing is a paradigm that complements and extends cloud computing by providing an end-to-end virtualisation of computing, storage and communication resources. As such, fog computing allow applications to be transparently provisioned and managed end-to-end. This presentation first motivates the need for fog computing, then introduced fog05 the first and only Open Source fog computing platform!
Data Sharing in Extremely Resource Constrained EnvionrmentsAngelo Corsaro
Ā
This presentation introduces XRCE a new protocol for very efficiently distributing data in resource constrained (power, network, computation, and storage) environments. XRCE greatly improves the wire efficiency of existing protocol and in many cases provides higher level abstractions.
Vortex II -- The Industrial IoT Connectivity StandardAngelo Corsaro
Ā
The large majority of commercial IoT platforms target consumer applications and fall short in addressing the requirements characteristic of Industrial IoT. Vortex has always focused on addressing the challenges characteristic of Industrial IoT systems and with 2.4 release sets a the a new standard!
This presentation will (1) introduce the new features introduced in with Vortex 2.4, (2) explain how Vortex 2.4 addresses the requirements of Industrial Internet of Things application better than any other existing platform, and (3)showcase how innovative companies are using Vortex for building leading edge Industrial Internet of Things applications.
Fog computing has emerged as a new paradigm for architecting IoT applications that require greater scalability, performance and security. This talk will motivate the need to Fog Computing and explain what it is and how it differs from other initiatives in Telco such as Mobile/Multiple-Access Edge Computing.
The Object Management Group (OMG) Data Distribution Service (DDS) and the OPC Foundation OLE for Process Control Unified Architecture (OPC-UA) are commonly considered as two of the most relevant technologies for data and information management in the Industrial Internet of Things. Although several articles and quotes on the two technologies have appeared on various medias in the past six months, there is still an incredible confusion on how the two technology compare and whatās their applicability.
This presentation, was motivated by the author's frustration with reading and hearing so many mis-conceptions as well as āapple-to-orangesā comparisons. Thus to contribute to clarity and help with positioning and applicability this webcast will (1) explain the key concepts behind DDS and OPC-UA and relate them with the reason why these technologies were created in the first place, (2) clarify the differences and applicability in IoT for DDS and OPC-UA, and (3) report on the ongoing standardisation activities that are looking at DDS/OPC-UA inter-working.
The Cloudy, Foggy and Misty Internet of Things -- Toward Fluid IoT Architect...Angelo Corsaro
Ā
Early Internet of Things(IoT) applications have been build around cloud-centric architectures where information generated at the edge by the āthingsā in conveyed and processed in a cloud infrastructure. These architectures centralise processing and decision on the data-centre assuming sufficient connectivity, bandwidth and latency.
As applications of the Internet of Things extend to industrial and more demanding consumer applications, the assumptions underlying cloud-centric architectures start to be violated as, ā for several of these applications ā connectivity, bandwidth and latency to the data-centre are a challenge.
Fog and Mist computing have emerged as forms of āCloud Computingā closer to the āEdgeā and to the āThingsā that should alleviate the connectivity, bandwidth and latency challenges faced by Industrial and extremely demanding Consumer Internet of Things Applications.
This presentation, will (1) introduce Cloud, Fog and Mist Computing architectures for the Internet of Things, (2) motivate their need and explain their applicability with real-world use cases, and (3) introduce the concept of fluid IoT architectures and explain how these can be architected and built.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
Ā
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
Ā
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
