In today’s modern computing world, high-speed networks with lower latency and reduced CPU utilization is essential when hosting modernized applications like streaming or real-time applications in which data should stream and real-time updates should happen smoothly. In this test, I’ll make VM1 the sender and VM2 the receiver. We present Azure Accelerated Networking (AccelNet), our solution for offloading host networking to hardware, using custom Azure SmartNICs based on FPGAs. The tool let’s you run it in single threaded and multi threaded mode. Accelerated Networking bypasses Azure's host and virtual switch to speed up network traffic for VMs (see diagram). Microsoft is promising that the use of Accelerated Networking with Azure VMs will "provide up to 30Gbps in networking throughput, free of charge!" AN provides consistent ultra-low network latency via Azure's in-house programmable hardware and technologies such as SR-IOV. In this blog post I’ve walked you through the improvement in the performance of the virtual machine with the reduction in latency and improvement of throughput when constrained by the choice of routing within our private vnet. AN provides consistent ultra-low network latency via Azure's in-house programmable hardware and technologies such as SR-IOV. Many of the latest Linux images available in the Azure Marketplace, including Ubuntu 16.04, Red Hat Enterprise Linux 7.4, CentOS 7.4 (distributed by Rogue Wave Software), and SUSE Linux Enterprise Server 12 SP3, work out of the box with no further setup steps needed. Accelerated Networking is a feature that significantly enhances the performance you get out of a virtual machine. The tool allows you to specify the packet size and the duration of execution, as well as advanced features of warm up and cooldown as well as buffering. Though this article provides steps to create a virtual machine with accelerated networking using the Azure CLI, you can also create a virtual machine with accelerated networking using the Azure portal.

For well-specified, non-evolving The steps are quite well documented in Microsoft docs. To put this in perspective, I am going to use the PsPing and NTttcp,exe to test latency and throughput to show you how poor the traffic flow is between the region pair for us at the moment. Reading Time: 2 minutes Back in January, we ran networking benchmarks across all of Azure’s instances. It confuses me why Microsoft doesn’t have accelerated networking enabled as default on all machines, but if you haven’t already set this up on your own virtual machines for even better performance. Get Azure innovation everywhere—bring the agility and innovation of cloud computing to your on-premises workloads. I’ll run the same test to gauge latency and throughput with the same parameters on the same size VMs, the only difference being that the machines now have accelerated networking enabled…, Histogram of distribution in latency of data transfer during the test,… As you can in the chart below over 99% of calls had < 300 ms of latency…, Let’s now look at these numbers with respect to the previous run…, Let’s now look at the throughput with respect to the previous run…. The deployment experience for AN has also been improved since public preview. I recently worked with my colleague Julien Stroheker delivering an AKS workshop for a customer. Accelerated networking can improve performance and reduce jitter, latency, and CPU utilization.” According to Kaushansky – and depending on workload and VM size – Check Point and customers have observed at least a 2-3 times increase in throughput thanks to Azure accelerated networking. To crunch this in layman terms, Accelerated Networking is processing your data in motion right at the virtual network card, which intern allows for greater throughput and lower latency in transit. We show that FPGAs are the best In addition to those noted, the performance and capacities listed in the following table have been generated under controlled lab conditions, using the recommended
