RTI Invests in Standards

DDS: The Interoperability Standard for Mission Critical Systems• Data Distribution Service from OMG• OMG: world’s largest systems

software standards org– 470+ members– UML, DDS, CORBA, more

• No vendor lock-in– ~12 implementations– Proven interoperability– Choice of middleware vendors– Choice of subsystem vendors

Navy Embraces OA

• Next-generation of the U.S. Navy Aegis Weapon System, by Lockheed

• Highly distributed system including radar, weapons, displays and controls

• Standards-based, high-performance middleware avoids vendor lock-in and future-proofs the architectural design

Government Adopts Standards

• Dominant in military– DISA: DISR mandated– Navy: Open Architecture,

FORCEnet– Air Force, Navy and DISA: NESI– Army, OSD: UCS– NATO, UK MOD, South Korea,

many more• Many other applications

– Air traffic control, industrial automation, transportation, medical

• Hundreds of active programs– Multiple interoperable

implementations

New Government Standards

Working as One™

Agenda

• DDS standard– Motivation– Applicability

• RTI Connext– Overview– What’s new

• RTI’s Infrastructure Community (IC) model– RTI DDS free as Open Community Source– Low-cost commercial licenses and support

Trend: Increasing System ScaleDrivers• Increased situational awareness,

information sharing• Responsiveness, timeliness,

speed of command

Implications• More CPUs, nodes, apps, data• More developers, teams,

suppliers, integration

System of systems

Cost Constrains ScaleLimits Information Sharing & Connectivity

O(n2)

Challenges

• Business– Cost reduction: lifecycle and procurement

Development, integration, maintenance, upgradesLegacy system integration and modernization

– Agility: timely fielding of new capabilities• Technical

– Scalability: information volume– Reliability and availability

Solution

• Interoperability– Easily share data across (sub)systems– Minimize need for integration– Goal: “plug and play”

• Modularity– Decompose systems into interoperable

components– Components can evolve and be competed

independently– Reduces complexity

• Decentralization– Systems of systems are inherently

distributed, span organizations– Eliminates performance bottlenecks

?

Achieving Interoperability

• Communicate via explicit, well-defined interfaces– Independent of:

• Implementation• Programming language• Platform (operating system, CPU type)• Physical location, proximity (edge, data center, cloud, same server)

– Standard network protocol• Integration requires no knowledge of internals

– No need for reverse engineering, code inspection• A lingua franca

– Integration effort is O(1) to O(n), not O(n2)• Components are evolvable, interchangeable, swappable,

shareable, reusable• Foundation of SOA, OA

DDS Enables Interoperability

Paradigm:Data-Centric Publish/Subscribe

• Components:– Publish the data they produce– Subscribe to the data they consume

• DDS middleware:– Routes data between matching publishers and subscribers– Maintains consistent shared state

DDS Data Centricity

Like a database• Simple integration

– Data and schema are discoverable– Producers and consumers are decoupled– New components don’t impact existing ones– Standard, application-independent CRUD operations: Create, Read, Update, Delete– …not specific to data source, type of processing/algorithms, or business processes

• Fosters information sharing• Single source of truth

– Robust– Temporal decoupling– Automatic state synchronization

DDS Data Centricity

Unlike a database• Event driven for real-time and low-latency processing• Decentralized

– Highly scalable: no performance bottlenecks or expensive servers– No single point of failure: non stop availability‑– Peer-to-peer communication: low latency

• Data cached locally for instant access

DDS Quality of Service

• Each component specifies its QoS capabilities and requirements– Data volatility: Durability, History, Lifespan– Data delivery: Reliability, Time based filter, Content filter, Deadline– High availability: Liveliness, Ownership, Ownership Strength

• DDS implements and enforces contracts

DDS QoS Benefits

• Reduces complexity and associated lifecycle costs

– Decoupling: publishers don’t need to know subscribers’ requirements

– Disparate subscribers almost always have different requirements

– Moves logic from applications to DDS middleware

• Efficiently scales with data volumes– Only required data is distributed, delivered– Reduces network and processor overhead

• Fault tolerance– Redundancy management– Components notified if QoS not satisfied or

connectivity lost– Can take remedial action
