Q. Why should I choose OpenSplice DDS?
A. That’s an easy question as it happens to be
much harder to find reasons why not to do so. I am
going to give you 10 good reasons to choose
OpenSplice DDS -- ready to go?

Reason #1
• Splice, OpenSplice DDS’ father, was the technology
from which the OMG DDS was most influenced
and from which inherited the Data-Centric
paradigm

Reason #2
• OpenSplice DDS is the most complete, and
strictly compliant, implementation of the OMG
DDS Standard on the Market.

Addressing Data Distribution Challenges
DDS is standard designed to address the data-distribution challenges across
The OMG DDS Standard a wide class of Defense and Aerospace Applications
‣ Introduced in 2004 to address the Data
Distribution challenges faced by a wide class
of Defense and Aerospace Applications
‣ Key requirement for the standard were its

ability to deliver very high performance while
seamlessly scaling from embedded to ultra-
large-scale deployments
‣ Today recommended by key administration
worldwide and widely adopted across several
different application domains, such as,
Automated Trading, Simulations, SCADA,
Telemetry, etc.
