Newbie NDIS question

NTDEV

Hi,

I am about to start writing a network port aggregation driver for Win2k. I
assume that I need to write a NDIS intermediate driver with a miniport
interface and a protocol interface. However, while talking to a Microsoft
driver tester, he mentioned that in Win2k there is a NDIS API that
configures NDIS to do port aggregation. It sounded like I could write an
application that configures NDIS, game over. I have been trying to find
documentation for this, but I can’t find any.

Help anyone?

Thanks,
John

By port aggregation, do you mean bundling adapters to balance the work load
that each miniport adapter carries and to enable a secondary miniport
adapter to take over work if the primary miniport adapter fails?

If yes, then read the reference doc of
NdisMPromoteMiniport/NdisMSetMiniportSecondary functions. Intermediate
drivers or miniports have to use these API to do something like that. There
is no magic user-mode interface that can ask any miniport to do that. Check
out the PASSTHRU sample to learn the usage of these functions.
