Network Infrastructure

The connectivity requirements of our modern world are still rising and so is the need for more complex and more reliable network infrastructure. The reliability of the wireless router at home becomes as important as the nearest UMTS base station because wireless IP telephony lies ahead. Beyond reliability for these devices, their security mechanism are critical as well, because it is critical to secure personal data that is continuously sent across networks.

Embedded Linux –
Over the last decade, embedded technology has advanced and evolved, almost beyond recognition. Where devices once stood alone and offered point functionality, today they are highly connected, extensible platforms.
Microkernel –
Microkernels have been receiving new attention during the recent years. After being discarded in the mid 1990s on the grounds of causing too much performance impact, the approach seems to be the answer to today’s computer problems: Today, computers generally do not suffer from lack of performance, but they often have severe reliability problems.
Paravirtualization –
Paravirtualization is the most common and widely used approach in the embedded industry. Paravirtualization requires a slight adaptation of the hosted environment to run on the virtualization layer, often refered to as hypervisor.
POSIX –
The portable operating system interface (POSIX) was developed due to the increasing need of application portability over several OSes. The first implementation was based on Desktop or Workstation OSes like Unix. But POSIX has already made its way in the embedded space.
Real-time –
Embedded applications present a range of requirements for performance, including real-time responsiveness. Intelligent devices may need to respond to external and internal events or generate their own time-based output to meet "hard" deadlines or merely to be "fast enough".
