Background (Why I want to do this)

My computer is connected to a flow control switch.The switch will limit the speed of each accessed IP to 10mbps.So I want to access multiple IPs and merge them to improve the network speed

What I have done so far

I refer to these articles:

  1. Windows-Creating Virtual Interface Over a Single Physical Interface
  2. Force an application to use a specific network interface
  3. https://www.altaro.com/hyper-v/hyper-v-network-teaming-understanding-link-speed/
  4. https://learn.microsoft.com/en-us/powershell/module/netswitchteam/new-netswitchteam?view=windowsserver2022-ps
  5. http://woshub.com/configure-nic-teaming-windows/

Now I have access to multiple IPs, and can reach the peak network speed of each network card through the curl command

all vEthernet can work

But I can't combine their network speeds to one network card through NIC Teaming

I try run New-NetSwitchTeam -Name "SwitchTeam01" -TeamMembers "vEthernet (net1)","vEthernet (net2)","vEthernet (net3)","vEthernet (net4)"

But I got a 10mbps vEthernet

SwitchTeam01 10mbps

What I need help with

  1. How to aggregate these virtual network cards and improve the speed?
  2. Is there any easier way to achieve what I am trying to do?

Network adapter Teaming does not aggregate bandwidth. Adapter teams are not created for bandwidth aggregation, but rather for load-balancing and fail-over.

This is because a network connection can only have one route connecting one network physical connection on each side of the connection.

You may create a team on four gigabit adapters, see that link speed report of 4 gigabits, and believe that you've created a 4 gigabit pipe. But in fact you have made a link aggregation of four gigabit adapters that act as one logical unit.

For more explanations, see this article.

When multiple physical paths are available, some technologies can make use of that to increase transmission speed. However, not adapter teaming. Some technologies, such as MPIO and SMB multichannel, work better when you leave adapters unteamed.

For more information, see the article Hyper-V and Network Teaming: Understanding the Link Speed.
