What does it mean for netstat -t

I see the help of netstat -t option says Displays the current connection offload state.

And I tried it in the windows command console.

The Offload State value display InHost.

What does Offload means to netstat?

Thanks.

Solution 1:

It refers to the TCP Chimney Offload feature which you can enable and disable on a network adapter. InHost means that the feature is disabled and offloading is not occuring. Offload means that TCP Chimney Offload is enabled on the NIC on which that connection is established.

TCP Chimney Offload overview

TCP Chimney Offload is a networking technology that helps transfer the workload from the CPU to a network adapter during network data transfer. In Windows Server 2008, TCP Chimney Offload enables the Windows networking subsystem to offload the processing of a TCP/IP connection to a network adapter that includes special support for TCP/IP offload processing.
