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 SmartWare access control lists are used for packet 
classification.

An access control list in SmartWare consists of a series of packet descriptions like “addressed to xyz”. Those 
descriptions 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 
discarded (“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. 

Some types of packets you do not have to tag with ACL. Voice and data packets from of for the SmartNode 
itself are automatically tagged with predefined traffic-class names: Predefined internal classes for voice and 
other data are:

local-voice—VoIP packets that originate from the SmartNode itself.
