Juniper Networks Inc.’s chief executive, Shaygan Kheradpir, is gone after less than a year on the job.  Conduct related to his dealings with a customer and his overall leadership being cited, but the lack of details left the company amidst rumours.

It seems the reason is that Kheradpir was fighting with the board over his performance and also the way he had interacted with a particular customer: As the company’s statement today noted, “The board and Kheradpir have different perspectives regarding these matters.”

His replacement is Rami Rahim, a 17-years’ Juniper veteran, whose most recent role was executive vice president and general manager, Juniper Development and Innovation.

“Rami is the right chief executive officer to lead Juniper,” stated chairman Scott Kriens in the company’s official statement Monday. “He is a talented leader who brings deep instincts about the networking industry, and enormous support from our employees and our customers. Rami has succeeded at every challenge he’s ever taken on at Juniper, and we couldn’t be more excited.”
