With this feature, an administrator can increase the size of network frames beyond 1500 bytes, which leads to a significant increase in network performance.
VLAN tagging and trunking
This feature allows you to configure virtual LAN (VLAN) traffic for virtual machines.
Live Migration
With this feature, you can migrate a virtual machine from one host to another host.
Static IP Injection
With this feature, you can replicate the static IP address of a virtual machine after it has been failed over to its replica on a different host. Such IP replication ensures that network workloads continue to work seamlessly after a failover event.
vRSS (Virtual Receive Side Scaling)
Spreads the load from a virtual network adapter across multiple virtual processors in a virtual machine. For more information, see Receive Side Scaling on Azure.
TCP Segmentation and Checksum Offloads
Transfers segmentation and checksum work from the guest CPU to the host virtual switch or network adapter during network data transfers. For more information, see Acceleration Mechanisms on NVIDIA ConnectX-5 NICs.
Large Receive Offload (LRO)
Increases inbound throughput of high-bandwidth connections by aggregating multiple packets into a larger buffer, decreasing CPU overhead. The feature is enabled by default on VMs running on Windows Server 2019 and later. For more information, see Acceleration Mechanisms on NVIDIA ConnectX-5 NICs.
SR-IOV
Single Root I/O devices use DDA to allow guests access to portions of specific NIC cards allowing for reduced latency and increased throughput. SR-IOV requires up to date physical function (PF) drivers on the host and virtual function (VF) drivers on the guest. For more information, see also Azure Accelerated Networking.
