Quality of Service is expected to become the most importantcommunications topic in the new millennium.

The acclaimed author, Gilbert Held, provides a comprehensive guideto obtaining a Quality of Service (QoS) capability in a Ciscohardware environment.

Today there are many aspects of the QoS 'puzzle' and Cisco isproviding users with a wide range of solutions. Some solutions arewell known but do not scale for use on the Internet or on a largecorporate Intranet. Other solutions must be used in conjunctionwith different schemes for true end-to-end QoS. That is where thisbook comes in, providing a guide to the various pieces of the QoSpuzzle.

Quality of Service in a Cisco Networking Environment:
* Is a one-stop location to obtain complete and concise informationabout achieving QoS for applications transported over local andwireless area networks.

* Provides a tutorial on the operation of different QoS techniques(IEEE 802.1p, 802.1Q, Differentiated Services, and RSVP).

* Describes Cisco Router QoS and Switch QoS commands.

* Gives examples of QoS configurations.

* Includes a series of easy to implement IP and Frame Relay trafficenhancement techniques.
Written for the local and wide area network planners and managers,local area network administrators and router administrators, everychapter initially guides the reader through the theory behind aspecific QoS technique. This information is then followed with aseries of Cisco command examples tailored to a specific QoStechnique. Readers learn both how a QoS technique operates and howto place it into effect in a Cisco environment.
