Differentiated Services (DiffServ)

set diffserv option [ off | on ]
Turns the DiffServ option off (default) or on. on enables the service and IP TOS bits are used, even if no
flows are defined. Consequently, if the end-point nodes provide TOS settings from an application that can
be interpreted as one of the supported states, the Gateway will handle it as if it actively marked the TOS
field itself.
☛
NOTE:
The Gateway itself will not override TOS bit settings made by the endpoints. Support for
source-provided IP TOS priorities within the Gateway is achieved simply by turning the Diff-
Serve option "on" and by setting the lohi-asymmetry to adjust the behavior of the Gateway's
internal queues.
set diffserv lohi-ratio [ 60 - 100 percent ]
Sets a percentage between 60 and 100 used to regulate the level of packets allowed to be pending in the
low priority queue. The default is 92. It can be used in some degree to adjust the relative throughput band-
width for low- versus high-priority traffic.
☛
NOTE:
diffserv lohi-ratio has been removed for VDSL, ADSL bonded units.
