###########################################################################################
# Bucket Ratio
# Default 1
#
# Upload and Download bucket ratios can be defined. These are used to calulate the
# "bucket size" or "queue length" (in packets) to be used for buffering upload and
# download traffic to facilitate rate restrictions defined in this config file or
# by FAS for individual clients.
# If a bucket becomes full, packets will overflow and be dropped to maintain the rate limit.
#
# To minimise the number of dropped packets the bucket ratio can be increased whilst
# still maintaining the configured rate restriction.
#
# ***CAUTION*** Large values will consume large amounts of memory per client.
#
# Consumed memory = (rate(in Kb/s) * bucket-ratio)KB per client bucket per direction.
#
# Eg. The maximum memory consumed per client for a downloadrate of 1000Kb/s and a
# Bucket Ratio of 100 will be: 1000 * 100 = 100000KB ie 100MB
# If 10 clients log in then potentially 1GB would be required if all of them became rate limited.
#
# If the client's average rate does not exceed its configured value within the
# ratecheck window interval (See RateCheckWindow option), no memory is consumed.
#
# If the rate is set to 0, the Bucket Ratio setting has no meaning
# and no memory is consumed.

# RateCheckWindow
# Default 2
#
# The client data rate is calculated using a moving average.
#
# This allows clients to burst at maximum possible rate, only blocking if the moving average
# exceeds the specified upload or download rate.
# This allows clients to burst at maximum possible rate, only enabling rate limiting if the
# moving average exceeds the specified upload or download rate.
#
# The moving average window size is equal to ratecheckwindow times checkinterval (seconds)
