Stacey Higginbotham takes a crack at explaining why Cisco’s announcement this week is a big deal for SDN, and Cisco:
> Cisco saw all of that play out and doesn’t want to find itself in Dell’s or HP’s shoes. So it is focusing on becoming a control point in the emerging virtualized stack and putting greater emphasis on software.
And, explaining what Cisco’s, well, ethos here may be:
> The networking world of old said it cared what the application wanted, but the application had to speak network’s language. So the application had to figure out if it needed more bandwidth or was experiencing latency issues or whatnot.
> But when the application comes first, this means you offer the application (and developers) a way to see how the network affects your application. So if something breaks, the developer doesn’t have to go looking for the networking code book to describe the problem because the networking infrastructure and software does the work.
and margins. If Cisco’s margins decline, the whole thing goes sideways.
