QoS Features and Components
The QoS feature is used to optimize network performance.
QoS provides the following:
QoS includes the following:
- Traffic Classification--Classifies each incoming packet as belonging to a specific traffic flow, based on the packet contents and/or the port.The classification is done by ACL (Access Control List), and only traffic that meets the ACL criteria is subject to CoS or QoS classification
- Assignment to Hardware Queues--Assigns incoming packets to forwarding queues. Packets are sent to a particular queue for handling as a function of the traffic class to which they belong.
- Other Traffic Class-Handling Attribute--Applies QoS mechanisms to various classes, including bandwidth management.
