network where bandwidth is plentiful. As applications like IP telephony and video-conferencing, and
mission-critical data applications have been implemented in the campus, it has become evident that
buffer management, not just bandwidth, is an issue that must be addressed. QoS functions, such as
classification, scheduling, and provisioning, are required to manage bandwidth and buffers to minimize
loss, delay, and delay variation.
variation because it is easy to illustrate how network performance can adversely affect voice quality.
Delay-sensitive applications, like video-conferencing over IP, and mission critical applications, like
ERP applications or mainframe SNA applications, have similar requirements of the network and are
adversely affected by packet loss, delay, and delay variation.
