Linux gains real-time networking stack

Jun 25, 2007 — by LinuxDevices Staff — from the LinuxDevices Archive — 1 views

An Austrian vendor of real-time networking stacks for automotive, off-highway, and aeronautics use has pledged to port its flagship technology to Wind River Linux. TTTech's claims its “Time-Triggered Architecture” (TTA) offers better safety, cost, and developer productivity, compared to event-driven architectures such as the CAN (controller-area network) fieldbus.

TTech said the move will allow developers of fault-tolerant distributed embedded computing systems to use Wind River's tools and target platforms. In particular, the port targets developers of distributed IMA (integrated modular avionics) systems that use ARINC 653 scheduling. According to TTTech, IMA reduces system complexity, weight, and lifecycle costs compared to system designs based on “many centralized modules.”


TTTech plans to support all of Wind River's OS platforms, including the General Purpose Platform, Linux Edition. The time-triggered technology will also be available with DO-178B Level A certification documentation, and support for Wind River's DO-178B certifiable version of VxWorks.

Delivery timeframes and pricing were not announced.
