VXLAN (Virtual Extensible LAN, virtual extended local area network) is a network virtualization technology, which is a two-layer VPN (Virtual Private Network ) technology based on an IP network and adopting a "MAC in UDP" encapsulation form. VXLAN can provide two-layer interconnection for decentralized physical devices based on existing service providers or enterprise IP networks, and can provide traffic isolation for different devices. VXLAN technology creates a large number of virtual extensible local area networks on existing network architectures by establishing VXLAN tunnels, with different virtual extensible local area networks identified using VNIs (VXLAN Network Identifier, virtual extensible local area network identifiers). At present, the Header of the message of the VXLAN has 24 bits, and can support the number of VNIs to the 24 th power of 2. The VXLAN technology has the following three main characteristics:

(3) Better utilization of network paths in the infrastructure, VLAN use STP (Spanning Tree Protocol ) to prevent loops and eventually do not use network links in the network to semi-block redundant paths, whereas VXLAN packets based on a three-layer header can fully utilize three-layer routing, ECMP (Equal-cost-Cost Multipath Routing) and link aggregation protocols to use all available paths.
