SUMMARY
With the continued convergence of multiple technologies on IP networks, QoS is becoming more important in the successful operation of customer
networks. As a collection of technologies, distinct QoS features can be applied in different combinations to solve an assortment of problems in
a network. The richness of the QoS feature set on the Cisco Catalyst 6500 provides network managers with a means to facilitate convergence and
prioritize mission-critical application data. More importantly, the nature of the Cisco Catalyst 6500 platform means that incremental changes in
QoS features can be accommodated, allowing the platform to grow to meet the new demands of the networks of the future.
