  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.
