Rate Type: 2 types are provided:
Limited (Maximum): specify a limited data rate for this policy. It also is the maximal
rate for this policy. As above FTP server example, you may want to "throttle" the outgoing
FTP speed to 20% of 256K and limit to it, you may use this type.
Guaranteed (Minimum): specify a minimal data rate for this policy. For example,
you want to provide a guaranteed data rate for your outside customers to access your
internal FTP server with, say at least, 20% of your total bandwidth. You can use this type.
Then, if there is available bandwidth that is not used, it will be given to this policy by
following priority assignment.
Ratio: Assign the data ratio for this policy to be controlled. For examples, we want to
only allow 20% of the total data transfer rate for the LAN-to-WAN direction to be used for
FTP server. Then we can specify here with data ratio = 20. If you have ADSL LINE with
256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps.
(For 0.9 is an estimated factor for the effective data transfer rate for a ADSL LINE from LAN
to WAN. For WAN-to-LAN, it is 0.85 to 0.8).
