Developing software running in resource-limited devices? Or are
you building systems that requirecertification? Connext Micro
provides a small-footprint communications infrastructure for
appli-cations where size matters. It helps your applications meet
stringent Size, Weight and Power (SWaP)requirements well beyond the
reach of traditional messaging middleware. With its small code
sizeConnext Micro also serves as the foundation for a certifiable
component in high-assurance systems.
RTI Connext MicroSmall-Footprint Messaging Software for
Resource-Constrainedand/or Certifiable Applications
Today almost any kind of device can be transformed into
an intelligent system that generates valuable information
for the enterprise. We have embedded devices in cars,
production-line environments and medical equipment andthey all
connect to a network or even the Internet. System
developers are faced with the challenge of making the data
produced by the wide range of embedded devices available
in real time to the enterprise for enhanced business insight
and intelligence.
Connext Micro provides a small-footprint modular
messaging solution for resource-limited devices that have
minimal memory, Flash, CPU power or no operating system.
By abstracting out low-level networking and communica-
tion details and providing a exible integration framework,
Connext Micro minimizes the amount of device or applica-
tion specic code that has to be created and reduces
development costs.
Additionally, Connext Micro is designed to become a certi-
able component in high-assurance systems. Connext Micro
satises the demanding real-time performance requirements,
stringent resource constraints, and certication processes
required by avionics and medical systems. By providing a
high-level and standards-compliant alternative to in-house
development, Connext Micro signicantly reduces the
development and certication costs and oers a lower-risk
solution.

Comprehensive Messaging Solution
Peer-to-peer communication
Connext Micro is an innovative, completely decentralized
architecture
that delivers consistent low-latency, high throughput and
scalability.
Applications directly exchange data in a true peer-to-peer
manner
no servers, message brokers or daemon processes act as
bottle-
necks or single points of failure.
Plug-and-play communication
Devices and applications are automatically discovered and
connected
at run-time. No system administration or directory service is
required,
allowing use in autonomous, dynamic and ad hoc systems.
Real-time Quality of Service (QoS)
Applications have comprehensive control over and visibility into
real-
time behavior, including timing, deadlines, resource utilization
and
system state. QoS can be specied per-topic and
per-subscriber.
Optimized publish/subscribe
Data can be multicast to multiple applications and devices
for
extremely ecient streaming data distribution. Messages are
routed
and ltered by the switch, not by software.
Wire eciency
The Real-Time Publish-Subscribe (RTPS) protocol is extremely
wireecient. Data is sent in a compact binary representation.
Most
metadata is only exchanged once, at discovery time.
Optimized for Small-Footprint Applications
Low memory requirement
Connext Micro is a library that links with your application. The
library
size is optimized for small footprint applications and memory
alloca-
tion is kept to a minimum.
Highly portable
Bundled source code enables developers to port Connext Micro
to
new operating systems, compilers or processor architectures.
RTI
Connext Micro has no built-in dependency on operating system
services. Applications can be implemented on platforms with
minimal operating system capabilities or no operating system at
all.
Processor support ranges from 16-bit microcontrollers with
32-bit
integer support to multicore Intel and PowerPC CPUs. Leading
enterprise operating systems, including Linux and Windows,
are
supported as well to ease application development and
testing.
Modular and user-congurable architecture
A small kernel provides the baseline capabilities for
publish-
subscribe messaging. By rebuilding the kernel from source
code,
additional features such as asynchronous notication,
reliable
communication and ltering can be compiled in, allowing
applica-
tion-specic trade-os between available features and
footprint.
Modular user-congurable architecture enables developers to
tradeoff available features and footprint.
Designed for High-Assurance Applications
Safety certication
RTI Connext Micro is designed to become certiable as a
component
of a complete system undergoing certication to RTCA/
DO-178B/C
(EUROCAE ED-12B/C). RTI provides services to support
certication
eorts by developing the necessary certication artifacts,
including
software development, verication, and conguration management
plans and software requirements, design and code standards.
Security certication
RTI Connext Micro is also well suited to certication under high
assurance
standards such the Common Criteria for IT Security (ISO/IEC
15408).
Small code size
With minimized lines of source code, Connext Micro provides
a
cost-eective foundation for rigorous certications.
Deterministic behavior
The code is developed using process guidelines that ensure
deterministic behavior. All memory allocation is done at startup
andno memory is freed at run-time.
Complementary Products
Connext Messaging is a universal communications backbone for
operational and enterprise applications. Combined, Connext
Micro
and Connext Messaging provide an integrated messaging
infrastruc-
ture spanning from small-footprint embedded devices to
high-end
enterprise servers.
Connext DDS is the most popular implementation of the DDS
stan-
dard, augmented with many powerful tools and run-time
services.
Connext Micro implements a subset of the DDS API and RTPS
wire
protocol for portability and interoperability with Connext
DDS.
