Up to 8 classes can be assigned in total, which SSG can use to mark packets either in the DSCP/TOS field of IP headers or in the VLAN/MPLS priority field. After that, QoS can be managed by an external platform. But we will consider the case when the SSG does it on its own. | + | Let’s divide the traffic into classes based on the protocol used.

| There are exist two approaches for limiting traffic for each class: to limit the maximum bandwidth that the traffic of corresponding class can occupy, or rely upon the mechanism originally provided by the SSG allowing to borrow bandwidth automatically. In the latter case, the SSG will begin to limit traffic based on classes only when the usage of the incoming traffic bandwidth approaches its threshold value.
