The 50 most powerful people in networking

Power requires balance. The 50 people we've selected as this year's most powerful network players sometimes make it look easy, but deciding when to take risks and when to play it safe is a true art.

Our list covers representatives from the vendor community - both perennials and up-and-comers - users, the government sector, those who make standards come to fruition, and thought leaders. No two people's jobs are exactly alike. Neither are their hobbies. One power player relaxes at the gold mine he bought in California. Another is restoring a classic Corvette. A third escapes to his Montana ranch when it's time to put work aside. Once again, it's all about balance.

POWER PERENNIALS

Chambers. Ballmer. McNealy. These names are as much a part of the network industry as the routers and switches moving the bits and bytes around the world. By virtue of the organizations they lead and the pervasiveness of the technologies over which they lord, they have become perennial figures on our power list.

John Chambers

President and CEO, Cisco

John Chambers is the only vendor executive to be ranked among Network World's most powerful since the Power Issue's inception in 1994. Back then, when he was vice president and president-elect, he earned his spot for his acquisition prowess, a skill he has demonstrated artfully throughout his stewardship of Cisco. In 2002, Chambers oversaw the acquisition of five more start-ups. Chambers' charisma continues to wow customers and bodes well for his visions of Cisco in new markets, such as storage and security (see story, "The 10 most powerful companies in networking" ).

Tim Berners-Lee

Director, World Wide Web Consortium

Next to icon Chambers, Berners-Lee is the only other person whose name has consistently graced the power list since 1994. His influence persists through his work with W3C - an organization that has grown in stature annually - and for his position as senior research scientist at the MIT Laboratory for Computer Science. He even continues to pile on the accolades as inventor of the World Wide Web: This year, Berners-Lee, a Brit, received the Albert Award from the acclaimed British Royal Society of Arts for his work with the Web.

Scott McNealy

Chairman, president and CEO, Sun

Sun was weaker in 2002 than it has been in a long time, but it has a history of rebuilding itself out of the sheer chutzpah of its leader, Scott McNealy. This stalwart retains his place among the industry's most powerful, a position he has enjoyed since 1995. Admittedly, McNealy faces bigger problems than ever before, with Sun's beleaguered stock price, fiscal losses, layoffs, mass executive exodus and market-share erosion to less-expensive Intel/Linux servers. Even so, the high-end server market is still Sun's to lose. And reasons abound to believe McNealy will shake Sun out of its troubles. Right now, he is duking it out with Microsoft for Web services, pushing into storage and helping shape future, intelligent infrastructures.
