Goal

There are parameters in Diameter Common -> MPs -> Profiles that we are allowed to change. But we cannot actually figure out how do they work. They are:

• CL1 Discard Percent (%)
• CL2 Discard Percent (%)
• CL3 Discard Percent (%)
• DOC Message Discard Percentage (%)

We Know which CPU load levels correspond to Danger of Congestion (DoC), CL1, CL2, CL3 (they are set in IDB table SysMetricThreshold). And parameters in question determine how many messages are shed at each level.

This document explains how message drop amount depends on this parameters (how DSR acts at each load level depending on them)?
