Embodiment 1

[0047] This embodiment is aimed at a Layer 2 virtual network VLAN (Virtual Local Area Network, virtual local area network). In the layer-2 virtual network, the virtual switch realizes the communication between VMs according to the MAC address of the VM. The network configuration verification method provided in this embodiment is used to verify whether the MAC address configured for the VM is correct, therefore, the verification content is the MAC address (physical address) of the VM.

[0048] It should be noted that the number of virtual switches in the VM and the virtual network is set according to the scale of the virtual network. For simplicity, this application uses a virtual network composed of two virtual switches and three VMs connected to the virtual network as an example for illustration. Of course, in practical applications, the virtual network may include multiple virtual switches, and a large number of VMs may communicate through the virtual network, and the netwo...

Embodiment 2

[0093] This embodiment is aimed at a layer-3 virtual network. In the three-layer virtual network, the virtual router forwards the route by identifying the IP address in the data packet sent by the VM according to the routing table, so as to realize the communication between the VMs. The network configuration verification method provided in this embodiment is used to verify whether the IP address configured for the VM is correct, therefore, the verification content is the IP address (network address) of the VM.

[0094] Same as Embodiment 1, in order to simplify the description, this embodiment uses Figure 5 The shown virtual network with a simple structure is an introduction to the solution of this embodiment. Such as Figure 5 As shown, the virtual network includes two virtual switches br-int and one virtual router. The network card device tap1 of the virtual machine VM1 is connected to the virtual switch br-int1, and the network card device tap2 of the virtual machine VM...

Abstract

The invention relates to the technical field of check on network configuration, and particularly provides a check system for network configuration under a cloud environment. In the check system, a configuration analysis module is arranged on each host where each piece of network equipment is located, only configuration information related to specific check content is uploaded to the configuration analysis module, the configuration analysis module summarizes each piece of configuration information into a forwarding vector and sends the forwarding vector to a comparison module for comparing; and during such a process, transmission and comparison data amounts are small, and check efficiency is high. In addition, the invention also provides a network configuration check method based on the cloud environment, the host capable of achieving the function of a configuration analysis module, and the other host capable of achieving functions of a scheduler, a configuration search module and a configuration comparison module.

Description

technical field [0001] The present application relates to the technical field of network configuration verification, and more specifically, to a network configuration verification method and related equipment in a cloud environment. Background technique [0002] Tenants can apply for network resources from the cloud platform, and the cloud platform builds a virtual network with a corresponding structure according to the needs of the tenant. A virtual network includes various devices like a physical network, but the network devices in a virtual network are virtual devices, such as virtual switches and virtual routers. VMs (Virtual Manufacturing, virtual host) connected to the same virtual network can communicate through virtual network devices. [0003] The cloud platform is a complex distributed system, which may cause errors in the configuration of virtual network devices due to system and other reasons, resulting in problems such as the inability of VMs to communicate wit...
