Certifiable networking stack for safety-critical embedded systems
Tuxera SafeTCPIP is a complete embedded TCP/IP v4 network stack developed to the ISO 26262 Automotive Safety Integrity Level (ASIL) B standard. The stack is suitable for integration with any system that requires a high level of safety-integrity and is mappable to other standards such as IEC 61508 and ISO 62304.
To guarantee the quality of the networking, automotive software developers may require a certifiable TCP/IP stack for integration into a safety product or environment. The de facto network standard for connected cars and in-vehicle safety systems is TCP/IP, but commercially available products are rarely developed to meet safety standards, are only partially certified, or are tightly integrated to a single vendor’s development system and RTOS.
Tuxera SafeTCPIP is an independently designed, off-the-shelf networking software stack that fills a critical market for automotive, industrial, or medical applications. It works on virtually all modern microcontrollers, with or without RTOS. Plus, it also includes a test suite to validate the RTOS resources required by the network stack.
SafeTCPIP is developed to full ISO 26262 Section 6 processes for integration with automotive systems that require a high safety-integrity level. It is supported by an independent software life cycle for maintenance. The exact verified product can be maintained and modified to safety standards independent of any other project that integrates SafeTCPIP.
The stack is built as a set of safety elements out of context (SEooC) as defined in ISO 26262-10, and deliverable as a distinct safety project with full life cycle maintenance. The reusability of the TCP/IP stack contributes to long-term stability and reduces development costs.
