# the netfilter uses the 'token bucket algorithm'
# it sometimes can be a bit 'unintuitive' how this rate-limit-algorithm works
#   the algorithm expects the packets, as defined by the limit, to be somewhat spread over the whole timewindow (second/minute/..)
#   token bucket punishes short-term overages beyond the burst capacity
# limit source code: https://github.com/torvalds/linux/blob/master/net/netfilter/nft_limit.c
# this script provides a way to easily test "rate-limit + burst" configurations
#   to get practical data you can simply run "tcpdump" on your target system and extract the packet-times from its output
