Assign the classifiers to flow groups and the flow groups to traffic
classes, with a different traffic class for each DiffServ code point
grouping within the DiffServ domain.
Give each traffic class the priority and/or bandwidth limiting
controls that are required for that type of packet within this part of
the domain. These QoS controls need not be the same for each
switch.
3. As packets leave the DiffServ domain, classify them according to the
DSCP values.
Assign the classifiers to flow groups and the flow groups to traffic
classes, with a different traffic class for each DiffServ code point
grouping within the DiffServ domain.
Give each traffic class the priority and/or bandwidth limiting
controls required for transmission of that type of packet to its next
destination, in accordance with any Service Level Agreement
(SLA) with the providers of that destination.
If necessary, assign a different DSCP value to each traffic class, to
be written into the TOS field of the packet header, to match the
DSCP or TOS priority values of the destination network.
Examples
The following examples demonstrate how to implement QoS in three
situations:
