☐ Some of the key challenges in
enabling the smart city vision are:
☐ The ability to gather data from a
dynamic environment
☐ The necessity to distribute and
process potentially very large
volumes of data
☐ Security

OpenSplice has a very simple goal:
☐ Making it easier to build, test, integrate, and deploy
high-performance, scalable, and fault-tolerant
OpenSplice DDS

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

Key Innovations[1/2]
Multiple 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
OpenSplice DDS

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 Innovations[2/2]
Unrivalled Connectivity

Copyright

☐ The new OpenSplice Gateway delivers integration
support for over 80 connectors to other messaging
technologies (e.g. JMS & AMQP), proprietary, and Web
OpenSplice DDS

Technologies (e.g. W3C Web Services & RESTful)

Tools
☐ The new OpenSplice Tester greatly simplifies the testing
of testing DDS-based distributed systems

with vehicle monitoring

☐ For instance we might want to pilot autonomous vehicles, or
perhaps we are interested in road safety, etc
OpenSplice DDS

☐ Too keep the application simple let’s focus on the following
aspects:
☐ Vehicle Status, e.g., where is the vehicle, how fast is it moving, in
which direction, etc.
☐ Collision Alert, e.g. is my vehicle about to hit something?

Data Model
☐ Based on the problem description we can easily figure out that

we need at least two different topics. One to represent the
vehicle status another to alert about possible collision
