Is anyone out there in need of a 4-way interconnect between T640 nodes for production IP networks? Is this a silly question? A few months back, we all discussed how the CRS-1 from Cisco was largely aimed at folks who were spending other people's money -- research & gov't types mostly.
The TX Matrix as announced Dec 3, 2004 (I just heard about on Slashdot today, so I admit I am a little behind) and have not heard a peep from anyone about it.
I can assume that because this doesn't scale as high as a CRS-1, it is going to be less expensive, but the question is... does it fill a need for someone today?
