How Embedded Connectivity Software from Axiros Works?

The client software is designed to be integrated into any kind of device, application or operating system. The connectivity towards the management/monitoring system is then provided by an intelligent and standards compliant data transport layer which can connect almost any kind of device via any kind of network and protocol to the required systems.

In short, the client software makes sure that the data transport layer can connect to the management/monitoring system, regardless of the underlying network or protocols.

Axiros’ embedded connectivity software is based on a modular and extendable architecture, which allows it to be easily integrated into any kind of device, application or operating system. The software consists of two main components: the client software and the data transport layer.

The client software is responsible for establishing and maintaining the connection to the management/monitoring system. It uses a plug-in system to support different protocols and networks, so that it can connect almost any kind of device to the required systems.

The data transport layer is responsible for transporting data between the client software and the management/monitoring system. It uses an intelligent routing algorithm to find the best path through the network, regardless of the underlying protocols or networks

AXACT Features & Functionalities

The Axiros AXACT CWMP client is used to provide TR-069 | TR-369 functionality to almost any kind of device. AXACT provides a fully Broadband Forum (“BBF”) standards compliant TR-069 | TR-369 protocol implementation together with a highly customizable data model, which allows a TR-069 ACS or USP Controller to configure and monitor every feature supported by the device.

  • Always supplied in C source code (C90/C99), C++ compatible

  • Comes with extensive documentation, example applications and testing support

  • Works on every POSIX1.b compliant system

  • Single process (non-threaded) event driven engine

  • May be integrated into existing applications, OS processes or tasks

  • Modular design for easy customization

  • Supports any TR-106 compliant model via automatic code generation

  • IPv6 and IPv4 operation supported

  • TLS 1.2/1.3 capable with extensive out of the box certificate handling

  • Libre-, OpenSSL, and mbedTLS support or custom implementation

  • UTF-8 support

  • Embeddable Lua interpreter and bindings for scripting functionality

  • Lightweight at around 150-400 kB binary size

  • Relies on libevent 2.x for communication, timers and buffer management

Concurrent USP and TR-069 Protocol Support

AXACT is the only offering on the market supporting both TR-069 and USP protocols within a single implementation, concurrently and without additional effort. This is ideal for migration scenarios or if you are a device vendor and want to appeal to customers with both traditional and the most-up-to-date infrastructure.

Highly Portable Source Code

AXACT is always delivered as source code and we take great care and pride in the fact that when it comes to portability in a device management stack, it really is second to none. The devices targeted by our customers are as diverse as nature: Linux, BSD, macOS, Windows, Android, iOS, proprietary OSes — out-of-the-box AXACT runs pretty much on any system with a POSIX compatible environment and for which a C (cross-)compiler exists. We also rely on the great CMake build system to make (cross-)compilation as seamless and comfortable as possible.

Integration into Existing Software

You don’t want to run your management protocols in a standalone application but need to integrate it with other software or directly into the operating system? AXACT is flexible: the main code compiles into a library which can easily interface with other programming languages (Lua, C++, Python, Java, Swift, Objective-C, Rust are some our customers frequently use) and integrate into your software, whether into a smartphone app, desktop application, device configuration/service manager or operating system.

Quality Assurance

All source code handed out by Axiros is extensively tested and packaged by our continuous integration system. Not only do we compile and run unit tests on a variety of Linux distributions in different versions, we also cross-compile to Windows and 32bit systems, have a number of additional functional tests and an array of source code analysis tools mercilessly flagging even just a hint of trouble with every change before allowing the packing process to create an archive. We’re happy to provide our customers with a summary report of this process for each archive we hand out.
