Detailed Description

The XMR (XIAN Metric Repository) Module - xmr.c.

The XMR - XIAN Metric Repository Module has the functionnalities of a database. It is responsible of recording the calculated values of the new cross-layer metrics introduced withinthe XIAN framework. It enables to update, to delete a value of a metric and to give accessible the metrics to the other system components
