Juniper switching boss talks technology challenges, Cisco Nexus 6000

Jonathan Davidson took over Juniper campus and data center switching when the two previously separate business units were combined following the departure of founding engineer R.K. Anand. Davidson has a service provider routing background at Juniper and Cisco, which is no coincidence -- after five years in switching, Juniper has been unable to mirror the success it had in its first five years in service provider routing. But it did start from zero and surpassed at least six other incumbent vendors to attain the No. 3 position in the market. The company has more than 20,000 switching customers cultivated through organic development, Davidson notes. And as Juniper moves forward amid a forklift upgrade facing its EX core switch base and after an initial misfire on the QFabric data center switch, it's focusing on customer demands for simplification, agility and automation. Davidson discussed some recent and future developments in Juniper enterprise switching.
