![]() ![]() Any client-server will be able to do that. Testing for LoopBack If you are reading this, it is probably because you already know loopback is not working and clicked the Help menu to get here. Network adapter MS NDIS 6.0 LoopBack Driver on local host. The loopback adapter lets a viewer on the server reach itself, as the loopback via the router is not functioning. You can fire up the client-server examples in LabVIEW and run those with localhost, as long as the machine happens to have a single NIC installed. I installed loopback adapters of Microsoft on my PC (Running Windows 10) and unfortunately. ![]() ![]() The local TCP traffic never passes through any adapter anyway.Īs described in the first sentence here (where the need for loopback is in place because they want to capture the truly local traffic): If this was a serial link, then sure - you would need a physical or virtual null modem installed. Passing data between executables on the same machine that happens to have the TCP stack loaded because it has a network interface anyway does normally not require a loopback adapter (unless any of the requirements I listed are in effect). Can you explain more what you mean by "link could be fully local"? The machine has 2- 1G and 4- 10G physical network adapters. The point of the loopback adapter is to use TCP to communicates to pass data between two different executables ( one C and one LV) on the same machine. LOOPBACK ADAPTER INSTALLStep by step : Install a loopback adapter on.

We've tried everything the web seems to offer, including a lot of things that have been supposedly deprecated. LOOPBACK ADAPTER HOW TOSo it's not the code, and we know how to configure hardware NICs for large data thruput. Resolution When using the Add Hardware Wizard to manually add a network adapter, choose Manufacturer 'Microsoft' and choose network adapter 'Microsoft KM-TEST Loopback Adapter'. The new name is 'Microsoft KM-TEST Loopback Adapter'. If we switch from internal TCP to connecting two 10G NICs in the same box, the data gets passed with no problem. The Microsoft Loopback Adapter was renamed in Windows 8 and Windows Server 2012. The loopback adapter is topping out somewhere around 500MB/s. The new system, however, needs a much higher continuous data thruput - somewhere in the neighborhood of 900 MB/s. Past iterations have worked great (after that little bug in LV11 was fixed). We'll see how long that lasts.Ī C developer and I are sending data via a MS loopback adapter between a C app and a LV app on the same machine (Windows 10). I'm supposedly retired, but then decided to go over to the Dark Side and become a contractor. ![]()
