# HNCOST06-BP01 Implement QoS policies for traffic prioritization
<a name="hncost06-bp01"></a>

 Configure QoS rules on on-premises routers to prioritize latency-sensitive traffic such as voice and video over bulk transfers such as data syncs. 

 **Desired outcome:** Guaranteed performance for critical workloads while optimizing bandwidth costs. 

 **Level of risk exposed if this best practice is not established:** Medium 

 **Benefits of establishing this best practice:** 
+  Prevents costly performance degradation for high-priority traffic 
+  Enables oversubscription of links without impacting critical workloads 
+  Aligns network costs with business value 

## Implementation guidance

+  Tag traffic with DSCP markers for on-premises traffic classification 
+  Apply shapers or queues on on-premises routers
