Does Juniper have too many SDNs?

Jim Duffy | March 19, 2015
Last week's product launch extends range of controllers and data center fabrics.

Though there appears to be no functional redundancy between all of Juniper's SDN controllers -- save for QFabric Director -- better integration between them could be articulated.

"Juniper probably should provide further elaboration on how Contrail/OpenContrail will work with Northstar and OpenDaylight, but there's no conflict or overlap," Casemore says.

Juniper's product launch last week was also big on emphasizing speeds and feeds, with the company trumpeting the 100G density supremacy of the QFX10000. But speeds and feeds are yesterday's news with the current industry emphasis on software abstraction and programmability.

Or is it?

"The QFX10000 is a spine switch, and Juniper wanted to make the case that its ASIC technology was necessary to drive that switch's performance characteristics, which is why we heard so much about speeds and feeds," says Casemore. "If this had been a ToR announcement, you would have heard more about the software capabilities. I think Juniper does understand what's happening in cloud datacenters, and I expect them to place considerable emphasis on network abstraction, automation, programmability, orchestration, and network disaggregation as we move forward."

Another ASIC development during Innovation Day was a custom 500G chip for Juniper's PTX core router. The ExpressPlus silicon performs more than 1.5 billion filtered operations per second and can drive 5x100G interfaces, Juniper says, which readies the router for 400G Ethernet.

Juniper also unveiled new line cards for the PTX 5000 and PTX 3000 which enable the PTX5000 to deliver 24Tbps of bandwidth in a single rack, or 30x100G per slot, the company says.

Juniper's optimistic that its Innovation Day innovations will be well received, perhaps having learned a hard lesson from the QFabric experience.

"We have a lot of confidence in these products because we pushed the limits of silicon and software, but with a true sense and understanding of the sweet spots in the market," Rahim says.
