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.
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 – 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.
Getting Started with OpenSplice DDS Community Ed.Angelo Corsaro
This document discusses OpenSplice DDS, a data distribution service (DDS) implementation that delivers performance, openness, and freedom. It provides an overview of key DDS concepts including topics, which define the type and quality of service of distributed data, and partitions, which organize communication within a domain. The document also touches on features like content filtering, local queries, and quality of service settings that control aspects of data delivery.
This presentation provides 10 reasons why you should choose OpenSplice DDS as you OMG DDS compliant technology. It analyzes standard compliance, technology, service, use cases and pedigree.
OpenSplice DDS v6 is a major leap forward with respect to the state of the art of DDS implementations; v6 is the first DDS implementation on the market to introduce (1) multiple deployment options, namely daemon-based and library-based, and (2) multiple programming paradigms, such as Pub/Sub, Distributed Object Caches and Client/Server, (3) universal connectivity to over 80 communication technologies via the new OpenSplice Gateway. All of this combined with an Open Source model, an active community and a strong technology ecosystem.
The OMG DDS standard has been witnessing a very strong adoption as the distribution middleware of choice for a large class of mission and business critical systems, such as Air Traffic Control, Automated Trading, SCADA, Smart Energy, etc.
The main reason for choosing DDS lies in its efficiency, scalability, high-availability and configurability -- through the 20+ QoS policy. Yet, all of these nice properties come at the cost of a relaxed consistency model no strong guarantees over global invariants.
As a result, many architects have to devise, by themselves – assuming the DDS primitives as a foundation – the correct algorithms for classical problems such as fault-detection, leader election, consensus, distributed mutual exclusion, atomic multicast, distributed queues, etc.
In this presentation we will explore DDS-based distributed algorithms for many classical, yet fundamental, problems in distributed systems. For simplicity, we'll start with algorithms that ignore the presence of failures. Then we will (1) demonstrate how these algorithms can be extended to deal with failures, and (2) introduce Paxos as one of the fundamental algorithm for consensus and atomic broadcast.
Finally, we'll show how these classical algorithms can be used to implement useful extensions of the DDS semantics, such as multi-writer / multi-reader distributed queues.
The document contains 30 questions and answers about Active Directory concepts. It discusses topics like the global catalog server, SysVol folder, replication between domain controllers, group policy order of processing, and the Windows startup process.

Why Implement DNSSEC?
Champika Wijayatunga from ICANN discusses the importance of implementing DNSSEC. DNSSEC introduces digital signatures to cryptographically secure DNS data and protect against threats like cache poisoning, spoofing, and man-in-the-middle attacks. While DNSSEC does not protect server threats or ensure data correctness, it does establish the authenticity and integrity of DNS data retrieved. Fully implementing DNSSEC allows businesses and users to be confident they are receiving unmodified DNS information. However, more needs to be done to increase awareness and provide turnkey solutions in order for widespread DNSSEC adoption.

September 2017 - Aftab Siddiqui presents on the Mutually Agreed Norms for Routing Security (MANRS), and how we can work together to improve the security and resiliency of the Internet's routing system.
18 September 2017 - ION Malta
What’s happening at the Internet Engineering Task Force (IETF)? What RFCs and Internet-Drafts are in progress related to IPv6, DNSSEC, Routing Security/Resiliency, and other key topics? We’ll give an overview of the ongoing discussions in several working groups and discuss the outcomes of recent Birds-of-a-Feather (BoF) sessions, and provide a preview of what to expect in future discussions.
Collaboration and shared responsibility are two pillars supporting the Internet’s growth and success. While the global routing system has worked well, it has significant security challenges that we must address. In this panel, security experts will discuss how we can create a culture of collective responsibility and improve the global routing system, including an introduction to the “Mutually Agreed Norms for Routing Security” (MANRS).
18 September 2017 - ION Malta
DNSSEC helps prevent attackers from subverting and modifying DNS messages and sending users to wrong (and potentially malicious) sites. So what needs to be done for DNSSEC to be deployed on a large scale? We’ll discuss the reasons for deploying DNSSEC, examine some of the challenges operators have faced, and address those challenges and move deployment forward.
18 September 2017 - Rick Lamb, ICANN, on DANE:
If you connect to a “secure” server using TLS/SSL (such as a web server, email server or xmpp server), how do you know you are using the correct certificate? With DNSSEC now being deployed, “DANE” (“DNS-Based Authentication of Named Entities”) has emerged allowing you to securely specify exactly which TLS/SSL certificate an application should use to connect to your site. DANE has great potential to make the Internet much more secure by marrying the strong integrity protection of DNSSEC with the confidentiality of SSL/TLS certificates. In this session, we will explain how DANE works and how you can use it to secure your websites, email, XMPP, VoIP, and other web services.
18 September 2017 - At ION Malta, Adam Peake discusses the IANA transition:
The IANA transition was successfully completed in October 2016 creating strengthened relationships between the IETF (Internet protocols and standards), Regional Internet Registries RIRs (IP addresses), and ccTLD and gTLD operators and TLD community and ICANN. A new organisation, Public Technical Identifiers (PTI), an affiliate of ICANN, is now responsible for performing the IANA functions and delivering the IANA Services on behalf of ICANN. The session will discuss these new arrangements and how they have enhanced ICANN’s accountability and transparency to the global Internet community. The session will also describe how ICANN is preparing for the Root KSK Rollover.
This document summarizes Finland's efforts to promote IPv6 adoption. It discusses the formation of the Finnish IPv6 Task Force to develop recommendations for IPv6 implementation. It also describes Finland's national IPv6 launch in 2015, where major ISPs enabled IPv6 for over 5 million broadband subscriptions. As a result, IPv6 usage increased significantly. The document discusses challenges faced during the transition like upgrading network equipment and changing attitudes. It concludes that while work remains, the launch was successful and IPv6 introduction costs can be limited by starting with easier implementations.
The document discusses Marco d'Itri's thoughts on the transition to IPv6. It describes the transition as ongoing, with no flag days, as IPv6 adoption grows. It notes that while IPv4 NAT is easy for access networks, it is difficult for servers. Many large content providers already use IPv6. The transition involves steps before IPv4 addresses ran out, the current transition period, and after the transition when IPv4 will be optional. IPv6 adoption is growing in several countries like Belgium and the US. Eventually IPv4-only islands will need to make themselves accessible over IPv6. The document provides advice on starting an IPv6 transition and offers a simple IPv6 addressing plan.
MANRS protects networks and reputations by preventing BGP leaks and spoofing that can saturate networks or attack infrastructure. Implementing MANRS filtering of BGP customers and spoofed traffic helps avoid these issues. It also allows other networks to filter your routes to prevent leaks. While RPSL is complex, registering autonomous systems and routes in the RIPE database through simple objects helps third parties and saves time for automation. Overall, MANRS establishes basic management practices that benefit networks by improving stability and security.
The document provides information about celebrating 25 years of the Internet Society and getting involved in various initiatives. It encourages readers to help shape the future of the internet, visit websites for more resources, follow social media accounts, and find presentation archives from a past conference. Contact details are also listed.
The document summarizes Thato Mfikwe's presentation at the ION Conference 2017 in Durban about the ISOC South Africa Gauteng Chapter. It provides details about the chapter's establishment, vision, pillars, membership reach across Africa and Europe, and projects from 2014-2016 and planned for 2017 focusing on community networks, policy engagement, outreach, and training. It also discusses ICT, internet governance landscape, topics at the ION conference including DNS, IPv6, cyber threats, and secure routing.

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
