Accelerated Networking Diagram

Benefits

The benefits of accelerated networking are:

  • Utilization of CPU will be decreased because the virtual switch is bypassed.
  • Lower latency, by removing the virtual switch from the datapath removes the time packets spend in the host for policy processing.
  • Reduced jitter, offloading the policy enforcement to the hardware removes that variability by delivering packets directly to the VM.

Limitations

There are three limitations for this capability :

  • It cannot be enabled for an existing NIC, we need to create a new one
  • We cannot attach the NIC on an existing VM, we need to deploy a new one.
  • This capability is only available for ARM deployments
