Chapter 7 Quality of Service (QoS)

LTE6100 User’s Guide

CoS technology includes DiffServ (Differentiated Services or DS). DiffServ is a new protocol and 
defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header. 

In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value in 
a matched packet. When the packet passes through a compatible network, the networking device, 
such as a backbone switch, can provide specific treatment or service based on the tag or marker.

Use this screen to enable or disable QoS, set the bandwidth, and select to have the LTE Device 
automatically assign priority to upstream traffic according to the IP precedence or packet length.

Click Network Setting > QoS to open the General screen.  

Network Setting > QoS > General

The following table describes the labels in this screen. 

Network Setting > QoS > General

Active QoS

Select the check box to turn on QoS to improve your network performance. 

You can give priority to traffic that the LTE Device forwards out through the WAN interface. 
Give high priority to voice and video to make them run more smoothly. Similarly, give low 
priority to many large file downloads so that they do not reduce the quality of other 
applications.
