WIND RIVER SUPPORT WITH VXWORKS Mission-critical systems increasingly rely on Ethernet connectivity betweenmodules or devices. Traditional Ethernet (IEEE 802.3 and 802.1Q) had no conceptof time regarding data delivery, and thus it was not possible to ensure that allreal-time data would arrive at its destination on time — especially as data loadsincreased. Deterministic system behavior thus could not be achieved. VXWORKS VxWorks is the world’s mostwidely deployed real-timeoperating system (RTOS).It enables the cost-effectivedevelopment of high-performance, reliable, secure,robust, safety-certifiedmission-critical systems,leveraging the latestprocessor advancements. Time-Sensitive Networking (TSN) addresses this problem, guaranteeing minimalnetwork latency and jitter, and it provides for bounded end-to-end delay and guar-anteed message delivery time. TSN also allows the transmission of time-sensitiveand non–time-sensitive data on the same network. The VxWorks®real-time operating system (RTOS) brings this TSN capability toembedded systems software developers natively — meaning without the needfor third-party add-ons. Further, VxWorks running as a guest OS on Wind River®Helix™ Virtualization Platform brings TSN capability to virtualized deployments. Development teams canuse popular programminglanguages and integratewith the Wind River StudioDevSecOps solution forhighly efficient developmentand testing. Deployment andupdates can be deliveredvia OCI-compliant softwarecontainer technology. Theseindustry-leading capabilitiessignificantly reduce time-to-market and drive innovation,new business, and revenue. >> Learn More About Time-Sensitive Networking ADDRESSING DIVERSE INDUSTRY USE CASES Industry-specific IEEE TSN profiles have been defined, enabling organizationsto more easily navigate the evolving TSN landscape by using those standardsapplicable to their markets.
