> Oh, the joy of ASR9k… I'm so glad we have chosen another platform. I think this is a bit unfair, of course vendors drop support to older platforms. And this whole problem with tomahawk and lightspeed transition isn't exactly new news, this has been known for 5years or so. It's a balance between being an early adopter and being supported for many years. I think for Gert committing on such an old platform was matter of density, no need for 9901 density, and I think this is where vendors need to wake up. Less dense and lower speed interface doesn't mean we can get away with TH1 or such ASIC, we still need full-blown NPU, large FIB, large RIB, large buffers. Vendors should release 1GE, 10GE, 100GE, 400GE optimised front-plates with latest gen NPU when ever new NPU happens, so what if you have 1% of NPU capacity in the front-plate, that's good problem to have, you can maybe cost optimise bit, by accepting from fab NPU which has lot of cores broken, or book less off-chip memory for delay buffer (less front-plate, less off-chip memory). Just because the new NPU can do 40x400GE, doesn't mean we don't still have applications for 1GE optimised devices with the same features and functions as the latest and greatest chip. -- ++ytti _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
