OpenSplice v6 Objective

OpenSplice v6 has a very simple goal:

☐ Making it easier to build, test, integrate, and deploy high-performance, scalable, and fault-tolerant distributed systems

☐ v6 makes this the art of the possible with the introduction of several ground breaking innovations

An Open TechnologyOpen Source☐ OpenSplice v6 Commercial Edition is available under both Open

Source (LGPLv3) and PrismTech Commercial Licenses. Our ongoing commitment to Open Source gives you complete security of supply and straightforward pricing; featuring no-cost deployment licenses for Core LGPLv3 functionality

Open Standards Compliant☐ OpenSplice DDS is the strictest implementation of the DDS OMG

Open Standard guaranteeing portability and interoperability across competing DDS implementations. The DDS standard is safe in our hands - our people invented DDS and are leading the way in its future evolution.

Headlines☐ The OpenSplice ‘Core’ Product for both Community and

Commercial Editions are licensed under LGPLv3 but the Commercial Edition (most up to date code base) requires an active subscription or commercial license

☐ No Run-Time fees for ‘Core’ Product

☐ V6 comes with a set of optional (but highly desirable) Commercial ‘Add-ons’ available under commercial license or subscription

Key InnovationsMultiple Architectures☐ Unique configurable Federated or Standalone deployment options

allow you to match performance, scalability and fault tolerance characteristics to evolving system needs; reducing both initial and lifetime development costs

Multiple Paradigms☐ OpenSplice v6 delivers the right solution to the right problem

through an expanding range of ‘interaction patterns’ including: Publish/Subscribe, Distributed Object Caches and Remote Method Invocation (RMI)

Key InnovationsUnrivalled Connectivity☐ The new OpenSplice Gateway delivers integration

support for over 80 connectors to other messaging technologies (e.g. JMS & AMQP), proprietary, and Web Technologies (e.g. W3C Web Services & RESTful)

Tools☐ The new OpenSplice Tester greatly simplifies the testing

of testing DDS-based distributed systems

The Grand Coulee Dam

☐ One of the first customers to benefit from OpenSplice DDS v6 has been the US Army Corps of Engineers (USACE) who have been using it for a major upgrade to the control system at the massive Grand Coulee Hydroelectric Dam project

☐ Grand Coulee is the largest power plant in North America, fifth largest in the world, with a total generating capacity of 6,809 megawatts via four different power houses containing 33 hydroelectric generators

The US Army Core Of Engineers on v6“Around two years ago we selected DDS as the real-time publish/subscribe messaging middleware for the dam upgrade program, convinced that it was the right technology for our needs.

OpenSplice DDS met all our rigorous performance and acceptance criteria. We went with the library based version of OpenSplice DDS v6 because of our need for an application solution that is simple to deploy. The Grand Coulee Hydroelectric Dam project uses about 150 computers which makes ease of deployment very important to us.

Although we do not currently use the shared memory deployment model in our architecture we are encouraged in knowing that OpenSplice DDS v6 provides a stable, uniquely switchable shared memory option should we desire to change our architecture characteristics.”

“To sum up: PrismTech provided us with a toolkit product – not consulting; their people listened, understood our unique application needs and supplied us with a DDS product solution that enabled us to deliver a state-of-the-art distributed control system.”

Dave Brown, Chief Architect Generic Data Acquisition and Control System (GDACS) US Army Hydroelectric Design Center

Deployment Options☐ OpenSplice DDS v6.x introduces a runtime

configuration parameter to select between a federated and standalone deployment option

☐ When deployed standalone OpenSplice DDS is a library that manages application-wide communication

☐ When deployed federated OpenSplice DDS is a set of libraries and daemons that manage node-wide communication

☐ The deployment options can be mixed at will (even within a single computing node)

☐ The same application can be deployed in federated and standalone mode (even on the same system)

“Simple when Sufficient.Performant when Required”

With OpenSplice DDS you can choose the

deployment architecture that makes

the most sense for your use case.

struct Region { long x0; long y0; long width; long height;};

local interface RobotCommands : ::DDS_RMI::Services { void start(); void stop(); void setSpeed(in long s); long getSpeed(); void setRegion(in Region r); Region getRegion(); };
