Introduction to Quality of Service for HP EFS
WAN Accelerators
You can configure QoS on HP EFS WAN Accelerators to control the prioritization of
different types of network traffic and to ensure that HP EFS WAN Accelerators give
certain network traffic (for instance Voice Over Internet Protocol) higher priority than
other network traffic.
QoS allows you to specify priorities for various classes of traffic and properly
distributes excess bandwidth among classes.
