Gigabit Ethernet offers built-in quality-of-service mechanisms that help
ensure that the most important data is delivered first. QOS improves network
service quality by providing different data service levels by data type.
QOS mechanisms offer the ability to define the available bandwidth, allowing
agencies to assign preferences to specific traffic types, applications or
users. With QOS, higher priority data types receive higher priority access
to bandwidth. For example, many shops will use QOS to prioritize data traffic
generated by voice-over-IP applications.
"If you want to make voice a higher priority than the rest of [your]
traffic, you can configure the device to do that based on the traffic itself,
or at the port," said Marshall Eisenberg, director of product marketing
at Foundry Networks Inc.
