Fault Tolerance Application Monitor
|
|
Description:
|
The FT application monitor component, named ftappmon, is a higher level component that analyzes possible consequences of an abnormal event on application threads and activates application mode change if required. The FT application monitor component provides a particular FT API interface to the application. The FT application monitor component is in relation with the FT controller component.

Fault Tolerance Controller
|
|
Description:
|
The FT controller component, named ftcontroller, is a low level component that handles abnormal situations (timing errors and/or abortion) and provides replacement behaviour for the faulty thread. Actually, the FT controller component is in relation with the POSIX Trace component by using a kernel stream trace in order to get system events related notably to application threads. After analysing and filtering of some particular event (PTHREAD_KILL), a decision making on the abnormal detected thread implies a transition from the normal behavior thread to the degraded behavior thread.
