Mike Volpi, the head of Cisco's routing business has quit his job, although his departure was not connected to a company reorganisation said a Cisco spokesman.
Volpi resigned from his position as senior vice president and general manager of Cisco's Routing and Service Provider Technology Group to "pursue new professional opportunities".
In the wake of Volpi's departure, the company is reorganizing its product development groups for telecommunications service providers and network operating system software to better respond to increasing business opportunities and customer requirements in these areas.
Senior vice presidents Tony Bates and Pankaj Patel, who had reported to Volpi, will take over management of the renamed Service Provider Technology Group. The group will focus on a growing part of Cisco's business - cellular, video, VoIP and landline telecommunications companies, said Charlie Giancarlo, Cisco's chief development officer.
Cisco is also creating a new Networking Software and Systems Technology Group, to be headed by Lele Nardin, previously vice president and general manager of the Mid-Range Routing business unit, and Bob Marinconz, previously vice president of engineering for Cisco's cable and video initiatives.
Although the reorganisation coincides with Volpi's departure, he didn't leave because of it nor were the changes made because he left. "It just means they all happened at the same time," said Wilson Craig, a company spokesman.
The departure of Volpi, a 13-year Cisco employee who has played key roles since the 1990s, won't rock Cisco because the company has deep management and a strong organization, analysts said.
"I do think it's a significant loss. I don't really think it's a crippling loss," said Yankee Group analyst Zeus Kerravala.
Cisco needs to reorganise because of the increasing importance of both its service provider business and its software, according to Frank Dzubeck, president of Communication Network Architects, a networking consultancy.
The seeds of the change lay in the development of Cisco's CRS-1 (Carrier Routing System), a massive platform introduced in 2004 for the core of service provider networks. The product has been a success, and Cisco's service provider business has been one of the brightest spots in mostly glowing recent financial reports. A separate division could better serve that important customer base, he said.
In building the CRS-1, Cisco created a new, modular software architecture that will allow the company to reuse the components in a broad range of products. And because of the growing integration of communications and computing, with networks playing roles in areas such as security and application performance, the network business is becoming more of a software business, Dzubeck said. Cisco needed a special division to leverage that new architecture across the company and handle the business of selling software, he said.
The politics of succession may have played a role in Volpi's departure, Dzubeck added. Chambers last year dropped the title of president, leaving that position vacant, while remaining CEO and taking over the chairmanship from John Morgridge. However, Chambers doesn't appear to be leaving the company soon, Dzubeck said.
As the reorganisation took shape, Volpi may have seen that it wouldn't take him higher up in the company, Dzubeck said.
"I think that he came to the realization that he wasn't going to get the president's job. What other job would he want?" Dzubeck said.
