Methods and apparatus are provided for improving the configuration,
management, and distribution of quality of service information in a fibre
channel fabric using zoning mechanisms. Configuration of Quality of
Service (QoS) information is made easy by using zones as a classifier for
flows. QoS information is included in zone objects, thereby using the
existing zone distribution mechanism to distribute QoS information.
Devices not part of any zones are placed automatically in the default
zone with a default QoS priority level. QoS information for a particular
packet is available as soon as the zoning information is obtained.
