Quick Tip: What is Accelerated Networking?
The accelerated networking provides consistent ultra low network latency via Azure’s in-house programmable hardware and technologies such like SR-IOV. By using Azure’s software defined networking stack, packets are offloaded from the VM CPU’s to the FPGA-based Smart NICs, thereby leading to compute cycles being reclaimed by end user applications running on the VM, putting less load on the VM, decreasing jitter and inconsistency in latency.
Starting with NDIS 6.30, the SR-IOV interface supports Microsoft Hyper-V performance improvements for virtualized networks on Windows Server 2012 and later versions of Windows Server.
The SR-IOV specification from PCI-SIG defines the extensions to the PCI Express (PCIe) specification suite that enable multiple virtual machines (VMs) to share the same PCIe physical hardware resources.
