Implementation Example

An example of managing QoS across the network is to define traffic classes and manage these on a network-wide basis. The four classes and their priorities might look like those outlined in Table�180.

Note: For information about DSCP (DiffServ Code Point), see "Diffserv" later in this chapter.

Table�180:�Examples of Classes of Service �
Service Class	Priority	DSCP Value	Type of Traffic
Highest Priority	7	56	Network Management Traffic, OSPF, Spanning Tree, etc.
Time Sensitive Traffic	5	40	Real-time voice, video conferences.
High Priority Data	1	8	SAP, Web, etc. Dependent upon your business.
Best Effort	0	0	Everything else.
