DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte.
DSCP Marking allows users to classify the traffic of the application to be executed according to
the DSCP value. See
Note: Make sure that the router(s) in the network backbone are capable to execute and check
the DSCP throughout the QoS network.

Rate Type: Two types are provided:
Limited (Maximum): Specify a limited data rate for this policy. It is the maximal rate for this
policy. As above FTP server example shows, if you want to "throttle" the outgoing FTP speed
to 20% of 100M and limit to it, please choose this type.
Guaranteed (Minimum): Specify a minimal data rate for this policy. For example, if 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 bandwidthm, please choose this type. Then, if the available
bandwidth 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, when we want to allow
only 20% of the total data transfer rate for the LAN-to-WAN direction to be used for FTP server, we
can specify here with data ratio = 20. If you have VDSL LINE with 100M/bps.rate, the estimated
data rate, in kbps, for this rule is 20%*100*0.9 = 20Mbps. (For 0.9 is an estimated factor for the
effective data transfer rate for a VDSL LINE from LAN to WAN. For WAN-to-LAN, it is 0.85 to 0.8).
Priority: The priority given to each policy/application. You may adjust this setting to fit your policy
/ application. For examples, you are allowed to specify two different QoS policies for different
applications. Both applications need minimal or higher bandwidth, besides the assigned one, if
there is any available/non-used one available, you can specify which application can have higher
priority by acquiring the non-used bandwidth.
High
Normal: The default is set to normal.
Low
For the sample priority assignment for different policies, it is served in a First-In-First-Out way.
