This mechanism allows to safeguard the buffer system, preventing higher 
priority   packages   run   out   space   with   lower   priority   waiting   to   be 

transmitted. 

It is necessary to take into account that if the thresholds for priority are 

not activated, there will be a single buffer to store packets of all priorities, 
so when buffer is full packets are discarded regardless of their priority. If 

you   want   higher   priority   packets   have   a   reserved   space   in   the   buffer, 
enable this option.

Bandwidth Limit

The bandwidth limit can set a limit on the total transmitted/received data rate, regardless of the priority 
assigned   to   them.  This  limit   is   activated   only   when   operating  mode   is  MDU.  The   minimum   value   is 
64Kbps and maximum 16Mbps in increments of 64 Kbps. 

Upstream Limit:  

Limits the traffic transmitted by a host device, ie , from host (Ethernet) to the 

coaxial. 

Downstream Limit

: Limits the traffic received by the Ethernet hosts of device, ie ,  from the traffic 

received by the coaxial towards hosts (Ethernet). 

Bandwidth limit is a feature that can be used in MDU distributions where 

the   installer   wishes   to   set   a   limit   on   the   bandwidth   used   by   users, 
programming   limit   on   slave   modems.   This   option   is   ignored   on    Home 

Networking mode.

Bandwidth limit overrides QoS priority. all packets are dropped if exceed 

limit, regardless of its priority

Bandwidth Limit with QoS

Bandwidth Limit allows operators/installers configure CoaxDATA™ products so that users can only use a 
certain bandwidth that have hired. However, this functionality can not preserve established QoS settings 
for data flows, ie, limit of bandwidth is for all traffic without distinguishing the priority of the packets.

To  ensure  QoS   parameters  are  preserved  even   if   there  is  bandwidth  limit  on  devices,  a  new   option 
named 

QoS For Bandwidth Limit

 is provided, which allows bandwidth limit setting considering QoS for 

flows transmitted, thereby providing important quality of service for certain applications such as video or 
voice transmission.

Limits the bandwidth used by users

, considering the priority of flows, so that the limit applies 

taking into account packets priority and those lower priority flows are discarded first.

Limitation of bandwidth occurs in the internal switch of device, which provides two output ethernet 
ports.   Therefore  

only   devices   that   have   an   internal   switch  

allow   you   to   implement   this 

functionality.
