High Throughput Ethernet

[The 2nd Nin]

I am looking to produce a C++ program capable of sending relatively
large packets via ethernet at a maximum rate of ~2.5KHz (2500 packets /
s) under a Win32 platform (2K/XP). Does anyone have any references or
ideas that could help with this as Winsock does not seem to give
sufficient speed with any reasonably sized packet ( > 500 Bytes).

Also is there a way to spoof an IP address on a LAN without creating a
driver for that purpose (this is for work, the software I am testing is
currently set up to accept commands only from a specific IP and I do
not wish to replace the existing terminal as I would have to replicate
a lot of its functionality).

Thanks

Not in C++. Neither the language nor the library provide network
functionality (as of yet, anyway).
