eProsima RPC over DDS - OMG June 2013 Berlin MeetingJaime Martin Losa
DDS is being increasingly selected as the foundation of many mission- and business-critical systems. Some of these systems are designed to be completely data-centric and asynchronous, while others prefer to maintain some interactions (such as placing an order, performing a computation, etc.) as traditional client/server, request/reply, interactions. As such, many DDS users would like to define Services as a collection of operations/methods, and invoke methods using DDS as the transport for requests, replies and exceptions.
This talk will introduce eProsima RPC for DDS, a high performance Remote Procedure Call framework based on DDS, 100% standards-based and open source.

DDS Advanced Tutorial - OMG June 2013 Berlin MeetingJaime Martin Losa
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.

TRUST BASED ROUTING METRIC FOR RPL ROUTING PROTOCOL IN THE INTERNET OF THINGSpijans
While smart factories are becoming widely recognized as a fundamental concept of Industry 4.0, their implementation has posed several challenges insofar that they generate and process vast amounts of security critical and privacy sensitive data, in addition to the fact that they deploy IoT heterogeneous and constrained devices communicating with each other and being accessed ubiquitously through lossy networks. In this scenario, the routing of data is a specific area of concern especially with the inherent constraints and limiting properties of such devices like processing resources, memory capacity and battery life. To suit these constraints and to provide the required connectivity, the IETF has developed several standards, among them the RPL routing protocol for Low powerand Lossy Networks (LLNs). However, and even though RPL provides support for integrity and confidentiality of messages, its security may be compromised by several threats and attacks. We propose in this work TRM-RPL, a Trust based Routing Metric for the RPL protocol in an IIoT based environments. TRM-RPL uses a trust management mechanism to detect malicious behaviors and resist routing attacks while providing QoS guarantees. In addition, our model addresses both node and link trust and follows a multidimensional approach to enable
an accurate trust assessment for IoT entities. TRM-RPL is implemented, successfully tested and compared with the standard RPL protocol where its effectiveniness and resilience to attacks has been proved to be better.
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.

FIWARE Wednesday Webinars - The Use of DDS Middleware in Robotics (Part 1)FIWARE
The Use of DDS Middleware in Robotics - 17 June 202
Corresponding webinar recording: https://youtu.be/pTkZk4VF0gY
This webinar, in cooperation with FIWARE Foundation Gold Member eProsima, will provide an introduction to core real-time technologies: FAST DDS, the most complete Open Source DDS for ROS 2, and Micro XRCE-DDS, the middleware for microcontrollers and micro-ROS.
Chapter: Robotics
Difficulty: 3
Audience: Technical Domain Specific
Speakers: Jaime Martin Losa (CEO, eProsima) and Francesca Finocchiaro (Team Manager micro-ROS, eProsima)
SDN programming and operations requires continuous monitoring of network and application state as well as consistent configuration and update of (forwarding) policies across heterogeneous devices. This is resulting in significant challenges.
Multiple open protocols such as OpenFlow, OF-CONFIG, OnePK , etc. are being adopted by different vendors causing an integration problem for developers.
Internet of Things applications are pushing the size and volume of data handled by SDN systems demanding more efficient and scalable protocols for information distribution and coordination of SDN devices.
This presentation will describe these and other SDN challenges and ways in which various open protocols, such as DDS, XMPP, AMQP, are being used to address them.
One of the most important challenges that system designers and system integrators face when deploying complex Industrial Internet of Things (IoT) systems is the integration of different connectivity solutions and standards. At RTI, we are constantly working to accelerate the Industrial IoT revolution. Over the past few years, we have developed standard connectivity gateways to ensure that DDS systems can easily integrate with other core connectivity frameworks.
This year, we developed a standard OPC UA/DDS Gateway, a bridge between two of the most well-known Industrial IoT connectivity frameworks. We are excited to announce that the gateway was just adopted by the Object Management Group (OMG).
In this webinar, we will dive deeper into the importance of choosing a baseline core connectivity standard for the Industrial IoT and how to ensure all system components are fully integrated. Attendees will also learn:
How the OPC UA/DDS Gateway specification was developed and how it works
How to leverage the Gateway to enable DDS and OPC UA applications to interoperate transparently
About the first standard connectivity gateway released with RTI Web Integration Service in Connext DDS 5.3
Gateways are a critical component of system interoperability and we will keep working to help companies accelerate Industrial IoT adoption.

Similar to Fiware - communicating with ROS robots using Fast RTPS (20)
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.

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?

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

18. DDS
DDS (Data Distribution Service for Real-Time Systems) is
a OMG specification for a pub/sub data centric model
(DCPS, Data Centric Publish/Subscribe) for Real-Time
data comms in distributed systems.
DDS is a networking middleware that:
• Simplifies and Standardizes data flows in distributed real-time
systems.
• Provides robust comms (no single point of failure) and efficient
(minimum latency)
• Provides all kind of QoS to shape the data flows and deliver
predictable results.

19. DDS
DDS uses the concept of Global Data Space. In this Space we define
topics of data, and the publishers publish samples of these topics.
DDS distributes these samples to all the subscribers of those topics.
Any node can be a publisher or a subscriber.
18
20. Why DDS? Decoupled model
Space (location)
• Automatic Discovery ensures network topology independence
Redundancy:
• It is possible to configure redundant publishers and subscribers,
primary/secundary and takeover schemas supported
Time:
• The reception of data does not need to be synchronous with the writing. A
subscriber may, if so configured, receive data that was written even before the
subscriber joined the network.
Platform:
• Applications do not have to worry about data representation, processor
architecture, Operating System, or even programming language on the other side
Implementation:
• DDS Protocol is also an standard. Different implementations interoperate.

• Standard API for
portability.
• RTPS can be
implemented over
any transport
• No central

24. Topics, Instances and Keys
• Topic: A set of similar objects, sharing a common
Data Type
• Instance: A particular object of the set
• Key: Fields of the Data Type to identify an object.

25. Demo
const long STR_LEN=24;
struct ShapeType {
string<MSG_LEN> color; //@key
long x;
long y;
long shapesize;
};
• 3 Topics:
• Square, Circle,
Triangle
• Color is the KEY
28. Example #1 - Hello World
We will use this data-type :
const long MSG_LEN=256;
struct HelloMsg {
string<MSG_LEN> user; //@key
string<MSG_LEN> msg;
};
29. Generate type support (for C++)
[Windows]
• Look at the directory you should see:
– solution-x64Win64VS2015.sln
– And Several other files…
• Open the Solution:
• Compile from visual studio
fastrtpsgen HelloMsg.idl -example x64Win64VS2015
-replace -ppDisable
30. Execute the program [Windows]
• C++:
– On one window run:
• binx64Win64VS2015HelloMsgPublisherSubscriberd.exe publisher
– On another window run:
• binx64Win64VS2015HelloMsgPublisherSubscriberd.exe subscriber
• You should see the subscribers getting an empty string…
31. Writting some data
• Modify HelloMsgPublisher.cxx:
/* Main loop */
do
{
if(ch == 'y')
{
st.msg() = std::string("Hello using cpp ") +
std::to_string(msgsent);
mp_publisher->write(&st); ++msgsent;
cout << "Sending sample, count=" << msgsent <<
",send another sample?(y-yes,n-stop): ";
}
32. How to Get Data? (Listener-Based)
// Listener code
void HelloMsgSubscriber::SubListener::onNewDataMessage(Subscriber* sub)
{
// Take data
HelloMsg st;
if(sub->takeNextData(&st, &m_info))
{
if(m_info.sampleKind == ALIVE)
{
// Print your structure data here.
++n_msg;
cout << "Sample received, count=" << n_msg << endl;
cout << " " << st.msg() << endl;
}
}
}
