Juniper plotting open source alternative to Cisco, VMware SDN controllers

Sees need for third 'de facto' software-defined network controller standard broadly supported by industry

Network World - SUNNYVALE, Calif. -- Juniper is working with other industry players on an open source-based controller for software-defined networks (SDN) that would be an alternative to proprietary offerings from VMware and Cisco.

Juniper hopes to have an open source SDN controller emerge as a de facto standard that's broadly supported by the industry, much like Linux, Apache and Hadoop have become in open source operating system, Web server and big data analytics, said Bob Muglia (pictured), executive vice president of Juniper's Software Solutions Division. He does not consider current open source SDN controllers, like Floodlight, Nox, Trema and others, to have attained that status yet.

"We think the likely thing and the best thing for the industry is to have an open source controller emerge that becomes a third standard controller," Muglia said in an interview with Network World this week. "One that is available broadly across companies and supports the broad set of capabilities that are needed. That has yet to emerge. And we are looking closely and working with a number of players in the industry to determine how it is likely to emerge."

COME ONBOARD! SDN bandwagon rolls ahead

A couple of the other participants Muglia mentioned are IBM and Microsoft. Muglia was a longtime Microsoft executive before moving to Juniper a year ago.

Isolating that de facto open source controller standard seems to be a priority for the company because VMware and Cisco, with their leadership positions in server virtualization and data center switching, and major investments in programmable networking, will have significant market positions in SDNs . VMware just bought network virtualization startup Nicira for $1.26 billion, and Cisco funded startup and potential spin-in Insieme Networks with $100 million, and may acquire it for $750 million more.

"We're actually working kind of hard on it," Muglia says of the open source SDN controller effort. "It's sensible for Juniper because we want to be disruptive in this space."

Juniper recently laid out its SDN strategy, which includes adding OpenFlow support to specific products next year. The company considers SDN, which makes multi-vendor networks programmable through software, a significant growth opportunity for Juniper because it's coming from a small installed base of LAN and data center switching. Juniper has about a 3% share of the $20 billion Ethernet switch market, good for a No. 3 position behind Cisco and HP, but small enough to have "a lot of upside," Muglia says.

And the data center and campus networks are where Juniper sees the immediate short-term benefits of SDNs because the infrastructure is geographically concentrated. Programming a network is harder when the elements are geographically dispersed.

"When a disruptive thing comes in like SDN, there's a significant opportunity to change some of the dynamics of the market share," Muglia says. "So we see this as being very, very positive for us."
