Abstract
With accelerated networking, network traffic arrives at the VM's network interface (NIC) and is then forwarded to the VM. All network policies that the virtual switch applies are now offloaded and applied in hardware. Because policy is applied in hardware, the NIC can forward network traffic directly to the VM. The NIC bypasses the host and the virtual switch, while it maintains all the policy it applied in the host.
Based on the documentation there are 2 notes to take care of:
- Only certain Virtual Machine sizes are supported for Accelerated Networking - more information can be found in this document.
- To use Accelerated Networking in an Availability Set, the Availability Set must be deployed onto an Accelerated Networking enabled cluster.
