20.7.6 Operation principle
The Denial of service functions (DOSFRNT, DOSLANAB and DOSLANCD) measures the IED load
from communication and, if necessary, limit it for not jeopardizing the IEDs control and protection
functionality due to high CPU load. The function has the following outputs:
• LINKUP indicates the Ethernet link status
• WARNING indicates that communication (frame rate) is higher than normal
• ALARM indicates that the IED limits communication
