摘要： In a system that uses a switched network and virtual links (for example, an AFDX, TT-ETHERNET, or TT-Gigabit ETHERNET switched ETHERNET network), the system is configured so that, for at least one virtual link, the end system that sources frames for that virtual link can change (for example, when an end system that was previously sourcing frames for that virtual link fails). The switches used in such a system are configured to be able to accept frames if there is such a change.

摘要： Methods and systems for a scalable self-checking processing platform are described herein. According to one embodiment, during an execution frame, a first processing element executes both a high-criticality application and a first low-criticality application. During that same execution frame, a second processing element executes both the high-criticality application and a second low-criticality application. The high-criticality application output from the first processing element is compared with that from the second processing element before the next execution frame, and a fault occurs when the output does not match. The low-criticality application is not duplicated or compared. This and other embodiments allow high-criticality applications to be appropriated checked while avoiding the over-dedication of resources to low-criticality applications that do not warrant self-checking.
