82 CONFIGURING THE HP EFS WAN ACCELERATOR
QoS allows you to specify priorities for various classes of traffic and properly
distributes excess bandwidth among classes. The HP EFS WAN Accelerator allows
you to decouple priority (in terms of delay) from the bandwidth allocation. This
provides the flexibility needed to support varying degrees of priority and bandwidth
traffic patterns, such as high-priority, low-bandwidth traffic patterns (for example,
Telnet). Many QoS schemes use the term priority to specify how to control the
excessive bandwidth among different classes. In the HP EFS WAN Accelerator,
priority actually refers to traffic delays and excessive bandwidth is shared,
proportional to the minimum bandwidth guaranteed for a specific class.
Enabling this feature is optional.
