- Is SNP broken?
- Posted by Pavel A. on May 15th, 2008
Just noticed this KB article -
http://support.microsoft.com/kb/948496
So what does this mean? are RSS and toe broken somewhere in NDIS or IP
stack, or the issues are caused by netcard drivers?

I think that this is saying:
IF you have TCP/IP Offload-enabled network adapter, then there is a
lot of software that doesn't know how to deal with TOE adapters with
the SNP. In fact, some TOE operations are implemented using a TCP/Ip
engine in the adapter itself and may not even be observable by various
filters. Hence - they break.
If you want the features of the non-TOE-aware services, then turn off
SNP.
Your thoughts?

No, I think it is the other way.
In the workarounds section, the "Method 1" says "The driver must meet
Network Driver Interface Specification (NDIS) 5.2 or a later version of this
specification."
This means if the Network Card has NDIS 5.2 driver, it works fine and you
don't need to turn off SNP.
Am I reading it right?

Hmm. We could assume that there is a ndistest suite for TOE, and all
shipping 3rd party drivers
have passed the formal and functional tests, and also some interop testing.
I'd rather agree with Thomas, but the KB article does not say anything
about any other software, besides of MS own components (dhcp, rdp client...)

Surely it doesn't make much sense. If the SNP is added and depends on
NDIS 5.2 miniports, then surely it should be bright enough to detect
whether NDIS 5.2 support is present. IIRC, there are OIDs for this
purpose.

Can someone from Microsoft clarify if SNP is still supported on Win2K3?

I've asked this because several approaches are developing to accelerate
tcp/ip processing - varying from filtering and "pre-cooking" L2 packets
before
they reach the OS (which uses standard drivers and IP stack), to
solutions that intercept sockets API in usermode and completely
bypass everything below it.
So if the 3rd party (or even MS) software can not cope with MS own IP
acceleration solution, are all these attempts doomed too?
