My motivation to implement XTP for Linux kernel is that XTP can be
better protocol than TCP in broad-band network, because XTP is free
from BD power limitation by separation of rate and flow control.

As far as I know, Packeteer's SkyX is only the product that implements
XTP. SkyX is mainly used for Satellite network which delay is too
long, but nowadays SkyX is used for broad-band network because XTP is
of great advantege to network delay in broad-band network.

Linux based network product is popular now, so adding XTP to Linux
kernel is useful for someone who develops Linux router, server and
etc, I think.

Thanks
