1. RTI Connext 5.2.0
The Real-time Connectivity Platform for the Industrial Internet of Things
Jan Van Bruaene - VP of Engineering
Vien Chan – Senior Product Manager

2. Codename “Eddy”

3. What we’ll cover
• What’s in the box
• Customer feedback
• Supporting new use cases
• The big boulders of this release
• Interoperability
• Transitioning to 5.2.0

5. New RTI Connext bundling
• Host bundle: all non-compiler specific files,
such as documentation, header files, tools,
services executables (e.g., Routing Service or
Persistence Service).
• Target bundle: libraries. Target bundles are
shipped in a new RTI packaging format.

6. New RTI Connext bundling – Cont.
• Package types: Core, Basic, Pro, Eval, and add-ons
– Core package includes basic libs,
does not include RTI applications/
services products.
– Basic, Pro and Eval all have
the same functionality.
The bundles differ in which
components are license
managed.
– Installers are now available
for all host package types.
– Targets are installed through
the new RTI package mgr.

7. New RTI Package Manager
The RTI package file (.rtipkg) is a compressed file containing:
– package.properties (file) describing the package
– MANIFEST.xml (file) containing a list of files to be installed.
– Compressed files and directory structure to be installed
The package manager handles backups and patch installations.
Use the RTI Package Manager (bin/rtipkginstall, or
from the Launcher GUI) to install target bundles,
patches, ports and feature accelerations.

8. New Directory
Structure
“SDK”
RunTime resources:
Resources used by
the RTI provided
tools, applications
and services.
Startup Scripts
Creation of a
User Workspace
When you start any
RTI application

12. Addressing customer use cases
Better support for large data or variable sized samples
• Enable the number of elements in a Sequence to be unbounded.
• Enable the number bytes in a String to be unbounded
• Support unbounded Sequences and Strings for key fields
• Support use of Content Filter with unbounded sequence and strings
• Support in the following languages: C, C++/CLI, .NET, Dynamic Data and Built-
in-types
• Limitations:
• Does not support Java (yet) (for generated Java Code. It is supported in Dyn Data.)
• Persistence Service does not support unbounded sequence/strings out-of-the-box.
• Recorder supports only serialized recording of variable sized samples.
• Excel currently already disallows work with unbounded types.
• Does not support Database Integration Service

13. Addressing customer use cases
Ability to serialize sample into buffer and deserialize sample
from buffer
• Two new TypeSupport operations to serialize a sample into a
buffer and deserialize a sample from a buffer.
• The sample serialization/deserialization uses CDR
representation.
• Supported in the following languages:
– Generated Code: C, C++, Java and .NET
– Dynamic Data: C, C++ (traditional and modern)

14. Addressing customer use cases
• TCP transport support for load balancers, tested with F5 hardware LB.
• New option to release the resources associated to a disposed instance. We
now also support the standard service_cleanup delay in PS.
• Several TCP and TLS enhancements: more scalable and robust
• Ability to supervise the end-point discovery provides additional level of control
of who can be discovered.
• Ability to Add Metadata Flags to Samples
• Allow out-of-order type definitions in XML configuration files
• Enable user to attach response to an application acknowledgement message
and notify the writer.
• Enable users to provide user-managed threads to the middleware.
… and tons more.
Please check the Release Notes for more details.

15. Stable connectivity platform for IIoT
Addressing product issues
• Better TCP transport! More robust and more scalable.
• Resolved communication issue for two participants on the same node when
one has SHMEM transport disabled.
• Resolved memory growth issues in more dynamic environments
• Dynamic Data API fixes
• DW/DR Liveliness QoS Policy fixes
• Resolved interoperability issue when using UDPv6 transport
• Large data sample repair fix
• Domain Participant creation fixes related when no shared memory segment
is available, or when no unique IP address is available (MacOS)
• Resolved issues related to DDS entity destruction.
Please check the Release Notes for a description of all bug fixes. We’ve spent a lot of effort
addressing product issues to make this a very stable release.

16. Big boulders
• Rtiddsgen2.0
• C++ PSM
• Queuing Service
• Data Visualization
• New Launcher

17. Code generation

18. Why a new code generator?
up to 10x faster
Code generation
Customizable
templates

19. Rtiddsgen2.0 - Continued
• Obfuscate option to share IDL with others
• New generation options (-create, -update) to avoid erroneously
overwriting previously generated example, type or make files
Rtiddsgen2.0 Limitations
• XSD-based code generation to be supported after 5.2 release
• No support for bitfields
• -corba, -metp  use the rtiddsgen1.0-based code generator. This
capability is provided through corresponding add-on products.

20. New C++ language binding

21. C++ PSM (Platform Specific Model)
• A New C++ API for C++03 and C++11
– A modern C++ API which works well with the
standard library
– An API that is efficient, expressive, easy-to-use,
and easy-to-learn.
– Generic programming, automatic resource
management, use of exceptions, C++11
features such as move operations.
• Same feature support as the other RTI
supported language APIs, including RTI
extensions and XML application creation.
Note: Traditional C++ PSM
is still supported

22. A P2P
distributed
application in
under 35 lines
of C++11 Code
(see blog post)

42. Interoperability
• UDPv6 class ID is now RTPS spec compliant
– Admin console will help you identify the compatibility issue
– Connext 5.1 backward compatibility mode
(dds.transport.use_510_compatible_locator_kinds property)
• Issue when using built-in topics to monitor Routing Service, Queuing
Service or Data Integration Service while mixing 5.1 / 5.2 versions
• Monitoring types are not backwards compatible
• Solaris Sparc Shared memory compatibility issue

43. New QoS values for
• New defaults for
– DDS_DynamicDataProperty_t.buffer_max_size
– DiscoveryConfig Built-In Writer
autopurge_unregistered_instances_delay
– DataReader Resource Limits:
dynamically_allocate_fragmented_samples and
max_fragments_per_sample
• HighThroughput and AutoTuning built-in QoS profiles
changed to resolve an issue where communication may
fail when writing small samples

44. Transitioning from 5.1 to 5.2
• Regenerate and recompile
• Automation scripts will need to be updated
due the new directory structure
– Change scripts which launch applications like rtiddsgen,
routing_service, etc.
– Change the build path to point to the new SDK directory
– Change library path to point to the new directory
