This article shows you what vmware's network architecture means. It's concise and easy to understand. It will definitely make your eyes shine. I hope you can gain something from the detailed introduction of this article.

overview

The network view displays a set of network objects available on vCenter. Network View enables you to create and manage network connections to vSphere Distributed Switches and view network connections to standard switch configurations.

vSphere provides two types of network architectures. vSphere Distributed Switch networks are used to manage virtual machines and host networks at the data center level, while standard switch networks are used to manage virtual machines and host networks at the host level.

standard switch

Standard switch networks are driven from the host level. A standard switch works like a network switch, detecting which virtual machine each virtual port is connected to and using that information to forward traffic to the correct virtual machine. Connect one or more port groups to the switch and specify port configuration options such as bandwidth and vlan labeling policies that apply to each member port. Each virtual machine NIC can be assigned to a port group. The architecture reference figure is as follows:

Uplink port groups connect a distributed switch to physical network adapters on associated hosts. For each uplink port on the vSphere Distributed Switch, each host can connect one physical network adapter to the vSphere Distributed Switch. The number of uplink port groups for vSphere Distributed Switch is equal to the maximum number of physical connections allowed per host to vSphere Distributed Switch.

A distributed port group is a port group associated with a vSphere Distributed Switch that specifies port configuration options for each member port. Distributed port groups define how to connect to the network through vSphere Distributed Switch.

Virtual machine networks connect to vSphere Distributed Switches through distributed port groups, which aggregate multiple ports into a common configuration and provide a stable anchor point for virtual machines to connect to identified networks.

A distributed virtual network consists of three parts

The level at which this occurs in the data is the level at which the vSphere Distributed Switch is created and hosts and distributed port groups are added to the distributed network.

Happens at the host level, which is the level at which host ports and network services are associated with a distributed network either through stand-alone host network configuration or through the use of host profiles.

This occurs at the virtual machine level, where virtual machine network cards are connected to distributed port groups either through standalone virtual machine network card configurations or by migrating virtual machine networks from the distributed network itself.

port group

Port groups are a concept specific to virtual environments and a mechanism for setting policies that govern the networks connected to port groups. Instead of connecting its vNIC to a specific port on the vSwitch, a virtual machine connects to a group of ports. A vSwitch can have multiple port groups. All virtual machines connected to the same port group belong to the same network within the virtual environment, even if they belong to different physical servers. Port groups can be configured to enforce policies to provide enhanced network security, network segmentation, better performance, high availability, and traffic management.
