6.7.8. PacketLimit

A rate limit solution based on packet numbers. The following parameters have to be specified:

PacketLimit settings

Figure 6.67. PacketLimit settings

  • time_unit: Time quantum for rate limitation time dimension.

  • packet_number: Maximum allowed packet rate in the given time quantum. It determines the speed or frequency at which packages can arrive

    Example 6.11. PacketLimit example settings
    • If the limit is 10/minute, and 5 packets arrive in one second, then only the first one will be accepted.

    • If the limit is 10/minute and 100 packets arrive in one minute, then approximately every tenth will be accepted evenly.

  • burst_number: Maximum initial number of packets to treated together when calculating the rate limit.

  • loglimit_time_unit: Time quantum for logging rate limitation.

  • logging_limit: The rate of dropped packets before logging is triggered.
