My point was, we have the ability = to generate high rate traffic, as long as we do tolerate a .1-1us = jitter. Beyond that, you do need some ixia-like solution. >=20 On the bandwidth side, can a modern sender with netmap really do a full = 10G? I hate the cost of an IXIA but I have not been able to destroy our stack as effectively with = anything else.
