SQUID DELAY POOLS

This defines the parameters for a delay pool.  Each delay pool has
 a number of "buckets" associated with it, as explained in the
 description of delay_class.

 For a class 1 delay pool, the syntax is:
  delay_pools pool 1
  delay_parameters pool aggregate

 For a class 2 delay pool:
  delay_pools pool 2
  delay_parameters pool aggregate individual

 For a class 3 delay pool:
  delay_pools pool 3
  delay_parameters pool aggregate network individual

 For a class 4 delay pool:
  delay_pools pool 4
  delay_parameters pool aggregate network individual user

 For a class 5 delay pool:
  delay_pools pool 5
  delay_parameters pool tagrate

 The option variables are:

  pool  a pool number - ie, a number between 1 and the
    number specified in delay_pools as used in
    delay_class lines.

  aggregate the speed limit parameters for the aggregate bucket
    (class 1, 2, 3).

  individual the speed limit parameters for the individual
    buckets (class 2, 3).

  network  the speed limit parameters for the network buckets
    (class 3).

  user  the speed limit parameters for the user buckets
    (class 4).

  tagrate  the speed limit parameters for the tag buckets
    (class 5).

 A pair of delay parameters is written restore/maximum, where restore is
 the number of bytes (not bits - modem and network speeds are usually
 quoted in bits) per second placed into the bucket, and maximum is the
 maximum number of bytes which can be in the bucket at any time.

 There must be one delay_parameters line for each delay pool.

 For example, if delay pool number 1 is a class 2 delay pool as in the
 above example, and is being used to strictly limit each host to 64Kbit/sec
 (plus overheads), with no overall limit, the line is:

  delay_parameters 1 -1/-1 8000/8000

 Note that 8 x 8000 KByte/sec -> 64Kbit/sec.

 Note that the figure -1 is used to represent "unlimited".

 And, if delay pool number 2 is a class 3 delay pool as in the above
 example, and you want to limit it to a total of 256Kbit/sec (strict limit)
 with each 8-bit network permitted 64Kbit/sec (strict limit) and each
 individual host permitted 4800bit/sec with a bucket maximum size of 64Kbits
 to permit a decent web page to be downloaded at a decent speed
 (if the network is not being limited due to overuse) but slow down
 large downloads more significantly:

  delay_parameters 2 32000/32000 8000/8000 600/8000

 Note that 8 x 32000 KByte/sec -> 256Kbit/sec.
    8 x  8000 KByte/sec ->  64Kbit/sec.
    8 x   600 Byte/sec  -> 4800bit/sec.

 Finally, for a class 4 delay pool as in the example - each user will
 be limited to 128Kbits/sec no matter how many workstations they are logged into.:

  delay_parameters 4 32000/32000 8000/8000 600/64000 16000/16000
