It's the Architecture, Stupid
Well, then, the question isn’t who’s going to have a ripping fast .11n AP, but rather who’s going to have an overall solution that supports such amazing throughput. A number of end-user clients have asked me whether their current products will be able to handle .11n. Well, maybe, but we’re already seeing announcements of controllers designed to provide the capacity to complement .11n APs.
But -- is a direct-forwarding architecture, a la what Colubris Networks Inc. , Siemens AG (NYSE: SI; Frankfurt: SIE), and Trapeze Networks Inc. are selling, a better approach? In this case traffic is forwarded or routed directly by the AP and need not go through the controller. In fact, what role should the controller play going forward? Is it going to devolve to a management appliance as the AP assumes more control-plane responsibilities? Are we on the road back to plump APs? And what of those firms that put in .11n and forget that they’ll really require Gigabit Ethernet for full performance? D'oh, indeed.
I’ve written a Farpoint Group Tech Note on this topic that you can find here. And I’ll have more to say on this issue in the coming months. For now, more questions than answers. So what else is new?
