General Quality of Service (QoS) Settings on ISA500 Series Integrated Security Appliances

Objective

The configuration of QoS provides optimized throughput and better performance by use of different priority values to the egress (outgoing) LAN, WAN or wireless differentiated traffic, such as Voice-over-IP (VoIP), other types of audio, video, streaming media, and the traditional IP data from the LAN. The preference is given to the highest priority data packets. This article explains how to enable QoS for the WAN, LAN and wireless traffic on the ISA500 Series Integrated Security Appliances.

Applicable Devices
