What tasks the system solves

The fines system performs the following functions:

• Generating fines
• Determining the number of fines
• IP address blocking

The fines generating function has the following parameters:

• The lifetime (ttl) of each fine point is fixed and is equal to 10 minutes.
• The storage time of fines for IP addresses that are not blocked is equal to 30 minutes from the date of the last fine point accrual.
• The fines are not accumulated for blocked IP addresses.

The function of determining the number of fines has the following parameters:

• The total number of fines can be positive or negative.
• If the total number of fines becomes less than 0, the accrual of fines will be temporarily blocked and the IP address will become trusted for a while.

IP address blocking function has the following parameters:

• The IP address will be blocked if the total number of its fines exceeds the threshold of 50 units.
• The IP address will be unblocked if the total number of its fines becomes less than 50 units.

Not to allow traffic from blocked IP addresses, resource traffic must pass through KDP Scrubbing Centers.
