High Touch / Low Touch Is this a measure of the amount of fiddle diddling required to get the chip to work as documented, or is it some other kind of code? For example a "High Touch" chip needs lots of fiddle farting because it was designed by a moron and every possible thing that can be programmed incorrectly is programmed incorrectly, whereas in a "Low Touch" chip all the defaults are already set to the most useful and rational setting so that it can be used without touching it to fix all the defects? Perhaps it is a measure of the babysitting required while the chip is running. "High Touch" chips require constant attention, nappy changes, positive re-inforcement of the settings, etc., while operating because they are inherently unreliable and badly designed whereas "Low Touch" chips once set up just work and require little ongoing supervision unless you want to change something? Or is it just a strange translation for functionality (as in High End / Low End)?

The only difference here is that there's suddenly more TCAM on the device, and I still don't see the above changing too drastically.Yeah OP is comparing high touch chip (MX104) to low touch chip (Jericho) that is not fair comparison. And cost is what customer is willing to pay, regardless of sticker on the box. No one will pay significant mark-up for another sticker, I've never seen in RFP significant differences in comparable products. Fairer comparison would be QFX10k, instead of MX104. QFX10k is AFAIK only product in this segment which is not using Jericho. If this is competitive advantage or risk, jury is still out, I lean towards competitive advantage, mainly due to its memory design. -- ++ytti
