A.Over leased lines，use the multilink ppp command to reduce latency and jitter，and to create Distributed Link Fragmentation and interleaving.
B.Use the service-policy command to attach a traffic flow to an interface on the router.
C.Use the ip rsvp bandwidth command to set a strict upper limit on the bandwidth NBAR uses，and toguarantee admission of any flows.
D.Use the policy-map command to define one or more QoS policies （such as shaping，policing，and so on） to apply to traffic defined by a class map.
E.Use the random-detect dscp command to modify the default minimum and maximum thresholds for the DSCP value.
F.Use the class-map command to define one or more traffic classes by specifying the criteria by which traffic is classified.
