Hi pupkin,

I am actually should do the same thing with the same SOC. And I am still considering different options. Have you tried to actually use any of these two protocols you posted (enet and udt)? I am really interested in how well they work and how close they get to 1Gb speed. And whether they can do the better job than TCP after all...

I need to send large quantities of data reliably from a Zynq-based device to
a PC.
I'm looking for a data transfer protocol which can get as close as possible
to wire speed on a dedicated 1Gb ethernet link. It would be nice although
not strictly required it it worked over arbitrary internet connections.

Currently I'm considering either porting http://enet.bespin.org/ or
http://udt.sourceforge.net/ to lwIp or rolling my own UDP-based protocol. I
will need support for zero-copy with scatter-gather DMA.

Has anyone done this before? Any suggestions?
