HNCOST06-BP01 Implement QoS policies for traffic prioritization

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
