Introduction In today's virtual environments, many VMware® customers are seeking a network virtualization solution that brings flexibility to data center networks. Virtual eXtensible Local Area Network (VXLAN), part of VMware vCloud® Networking and Security™, addresses this networking challenge. VXLAN creates logical networks for virtual machines across different physical networks by encapsulating Ethernet frames in a user datagram protocol (UDP) VXLAN header. By encapsulating layer 2 packets, VXLAN effectively creates layer 2 networks on top of layer 3 networks. In addition, VXLAN can support 16 million layer 2 networks compared to VLAN, which supports only 4,096 networks. This chapter describes the hardware and software configuration for a sample network, and illustrates the benefits of VXLAN offloading through the use of a network simulation using Ixia® IxChariot®. Chapter 2 describes how to configure VXLAN offloading on the sample network.
System Description and Topology Table 1-1 describes the hardware and software elements for the sample network.

1–Introduction Benefits of VXLAN Offloading
Benefits of VXLAN Offloading The additional encapsulation required in VXLAN increases the packet processing load on the CPU, which decreases network performance. The ProductName includes stateless hardware offload, which moves VXLAN packet processing to the adapter hardware, freeing the CPU for other critical host and VM processing. The benefits of VXLAN offloading become evident when the network is simulated using Ixia IxChariot. IxChariot is a widely-used network tool for simulating real-world applications to predict device and system performance under load conditions. IxChariot assesses the performance characteristics of any application running on wired and wireless networks. Table 1-2 describes the simulation details.

1–Introduction Benefits of VXLAN Offloading
Figure 1-2 shows the simulation results where the average increase in throughput across all I/O sizes for VXLAN offload over no offload is 16 percent. This increase ranges from 7 percent at 1K bytes to 24 percent at 64K bytes. In networks with lesser-equipped servers (fewer or slower processors), the increase in throughput may be greater. The VXLAN offload feature optimizes network traffic, thereby increasing performance across all I/O sizes.
