High-Performance Embedded Web Server For QNX

Real Time Logic Announces High-Performance Embedded Web Server For QNX
Real-Time OS

RealTime Logic’s Barracuda web server simplifies remote real-time
monitoring and control of distributed embedded systems

March 3, 2006 - Real Time Logic, the world leader in device management
software for telecommunications, medical and automotive applications,
today announced the availability of the industry’s most powerful
embedded web server for the QNX real-time operating system. The web
server makes it easy to remotely monitor, control, and configure
embedded applications running on the QNX real-time operating system.
Barracuda is particularly effective for complex distributed systems,
enabling browser clients to monitor and control multiple devices at the
same time with full authentication, authorization, and encryption

“Barracuda is an industrial strength embedded web server, optimized for
sophisticated distributed processing applications”. “Barracuda extends
the distributed processing capabilities of the QNX real-time operating
system, making it easy to monitor and control multiple QNX nodes in real
time from the same remote browser.”

Barracuda utilizes the standard HTTP protocol to facilitate secure
transfers of user data, firmware, and application control data between
clients and servers. Unlike conventional HTTP-based clients, Barracuda
provides an EventHandler that enables HTTP- and Java-based clients to
monitor and control multiple event-driven embedded applications residing
on multiple devices in real time. The full-duplex, asynchronous
EventHandler protocol stack, which sits on top of HTTP, gives
EventHandler clients the same benefits as regular HTTP clients,
including the ability to bypass proxies and firewalls.

The EventHandler uses a compact (32 kbytes), real-time, Secure Socket
Layer stack (SharkSSL), which supports hardware crypto encoding and
decoding for common hardware crypto engines, to establish secure
client-server communications.

Barracuda’s EventHandler features install-on-demand technology that
enhances device efficiency and reduces memory requirements by minimizing
the amount of application code that must be stored in local device
memory. With Barracuda, users can store their device application code on
a remote server. When the user activates an URL to an EventHandler-based
application, Barracuda installs the DHTML browser application on demand.
Barracuda also supports Sun’s Web Start Technology, which enables
remotely hosted Java applications to be installed on demand, in the same
way that Java applets are downloaded on demand to PCs.

Barracuda’s CSP language (similar to Active Server Pages) makes it easy
to generate traditional server web-applications. With CSP, developers
can embed C or C++ programs directly into an HTML template page created
by an HTML designer. The rich C and C++ API, modeled after enterprise
server APIs, provides methods that make it easy to design applications
based on the common Model-View-Controller paradigm. The object oriented
virtual file system makes it possible to delegate user requests, such as
HTTP GET and HTTP POST, to any resource or resource collection.

Barracuda comes with a number of ready to use resource collections,
including the ability for clients to read and write files to any
directory in an embedded file system, and read files directly from
within ZIP files. Resources can be dynamically installed and removed
during runtime. Thus, a ZIP file can be uploaded using HTTP(S) and
dynamically installed on the virtual file system.

Barracuda provides a number of advanced plug-ins, including web
services, such as SOAP, and a web interface to any SNMP MIB. Barracuda’s
host tools include a graphical MIB editor and compiler, Interface
Definition Language (IDL) compiler for the EventHandler, and a
compiler/linker for the CSP scripting language. Barracuda also provides
a host simulation environment that enables designers to develop, run and
test their code on any Unix or Windows machine without requiring target
