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.
Priority: Specify the priority for the bandwidth that is not used. For examples, you may specify two
different QoS policies for different applications. Both applications need a minimal bandwidth and
need more bandwidth, beside the assigned one, if there is any available/non-used one available.
So, you may specify which application can have higher priority to acquire the non-used bandwidth.
High
Normal: The default is normal priority.
Low
For the sample priority assignment for different policies, it is served in a First-In-First-Out way.
