Comments on: On the Death and Rebirth of IOS – Why Did It Take So Long ? http://etherealmind.com/on-the-death-and-rebirth-of-ios/ Network design, architecture, thinking, working. Tech.

I mean, compared to Juniper's low-end boxes, it has more resilience, and I suppose it has more resilience than we're used to, so things are moving in the right direction. Actually - I had a demo of that Telepresence thing a month or so ago - until then, I didn't care about it either. It was very impressive though - almost like being in the same room - you forgot you were on camera quite quickly. Just wish I could afford one...

I keep scratching at the itch that the Nexus 7000 and the ASR 1000 and something doesn't seem quite right. There is always something missing isn't there. I suspect that the HA features were removed by marketing since they wouldn't sell so many 7600 chassis. The rise of marketing at Cisco does worry me. Gosh, when they released the ASR they rode a videoconferencing message over the top of it. As if anyone remotely cares about videoconferencing, the whole technology is a flub and they are hoping that marketing will pick up the numbers sigh I agree with you, it doesn’t quite seem to match the HA features that I would expect.

It certainly looks to be filling a big gap above the 7200 in terms of forwarding capacity. When I saw a presentation about it, I had a concern though - there's only dual route-processor capability in the 1006. The 1004 and 1002 use a kind of software redundancy - essentially a microkernel that runs two copies of IOS at the same time. If theres some kind of crash of that kernel, you've lost your resilience. I can't help thinking that one of the big things in this is this QuantumFlow processor. It is extremely powerful and new features can be 'switched on' according to your need. What this boils down to is the licensing of features more tightly, fewer code trains and more profit for Cisco. Lets hope it is less trouble for the consumer too.
