The Denial of service functions (DOSLAN1 and DOSFRNT) 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
