Defining the access control list profile
Packet classification
The basis for providing any QoS lies in the ability of a network device to identify and group specific packets.
This identification process is called packet classification. In IPLink access control lists are used for packet classi-
fication.
An access control list in IPLink consists of a series of packet descriptions like “addressed to xyz”. Those descrip-
tions are called rules. For each packet the list of descriptions is sequentially checked and the first rule that
matches decides what happens to the packet. As far as filtering is concerned the rule decides if the packet is dis-
carded (“deny”) or passed on (“permit”). You can also add a traffic-class to the rule and if this rule is the first
matching rule for a packet it is tagged with the traffic-class name.

Profile
The service-policy profile
defines the arbitration
mode and order in which
packets of different
classes are served.
This interface is used as
access link and normally
represents the bottleneck
of the system.
