LTE QoS is based on a traffic flow template pushed to the end device’s LTE modem from the network. Historically, the flow
template was based on a 5-tuple (source and destination IP addresses, protocol, source and destination port numbers). A
use case is streaming of pay-per-view video. This method of classification is limiting for enterprise LTE QoS usage.
Verizon and Cisco have partnered to leverage LTE technology for mobile device connectivity with Private Network Traffic
Management. The efforts include deployment options, network enhancements, and testing, which meet today’s LTE open
3GPP standards. Below are the key characteristics:
-
Verizon offers two bearer channels across an LTE Private Network connection. Both bearers are part of a
single logical connection. The service rate options are 0.5Mbps or 2Mbps for the bearer supporting
Mission Critical Class-of-Service (CoS).
-
Traffic is classified and placed onto the appropriate LTE bearer based on the ToS byte of an IP packet
(e.g. DSCP value). This allows integration with an organization’s existing QoS model per generally
accepted practices (mark DSCP close to the source and treat traffic across the network based on DSCP
in each packet). Multiple applications can map to the bearer offering enhanced QoS.
-
The PNTM bearers include the dedicated bearer (supports all packets marked DSCP CS3, AF3x, CS4,
AF4x, CS5, EF), and the default bearer (supports all other packet markings). The default bearer provides
best effort service, while the dedicated bearer provides preferential treatment (Mission Critical CoS) up to
the service rate. Traffic above the service rate in the dedicated bearer is dropped.
