Problems solved by technology

[0003] In the traditional network, VLAN (Virtual Local Area Network) technology is used to realize the isolation of tenant communication, but the VLAN ID is only 12 digits, which can only realize the isolation of 4096 tenants, which is far from enough for the network environment of cloud computing

Embodiment Construction

[0023] In a networking structure, a VM (Virtual Machine, virtual machine) on a server accesses a VXLAN network through a VTEP (VXLAN Tunnel End Point, VXLAN Tunnel End Point). Multiple virtual machines can be created on one server, and different virtual machines can be connected to the same or different VXLAN instances. A VXLAN instance is an independent forwarding entity in the VXLAN network. VMs connected to the same VXLAN instance belong to the same logical Layer 2 network and communicate with each other at Layer 2. Layer 2 forwarding between VMs connected to different VXLAN instances is isolated from each other. A VXLAN instance can be used as a method to distinguish different tenants, and a VXLAN instance is created for each tenant. VXLAN instances are usually distinguished from each other by identifier (ID, IDentity). The identifier of a VXLAN instance can be specified by the network administrator, or can be automatically generated when the VXLAN instance is created. The...

Abstract

The invention provides a method for disposing a VXLAN. The method is applied to a VTEP. The VTEP and other VTEPs in a network where the VTEP is located are neighbors. The method comprises steps of: sending a VXLAN information notification message to the neighbor VTEPs, wherein the VXLAN information notification message carries the identifier of a VXLAN case configured in the VTEP; establishing a tunnel to a certain neighbor VTEP if the same VXLAN cases are configured in the neighbor VTEP and the VETP; and associating the established tunnel with the VXLAN cases commonly configured in the VETP and the neighbor VTEP. The method and device automatically discover the VXLAN, relieve the burden of a network administrator, and reduce network maintenance cost.

Description

technical field [0001] The present application relates to the technical field of network communication, and in particular to a method and device for deploying a VXLAN (VirtualExtensibleLocalAreaNetwork, Virtual Extended Local Area Network). Background technique [0002] In recent years, data centers have become the first choice for enterprises in information technology construction. A large number of cloud computing networks are deployed in data centers, and virtualization has almost become a basic technical model in cloud computing, including server virtualization, storage virtualization and network virtualization. In a virtualized environment, many tenants share cloud services and resources. Taking the public cloud as an example, the application system designed by the cloud service provider will accommodate many tenants in the same environment. The virtualization resources of different tenants are independent and isolated from each other, which can better protect the pri...
