CacheFlow Appoints Brian NeSmith as CEO; Former Ipsilon CEO Brings Network Industry Expertise to Internet Company.

SUNNYVALE, Calif.--(BUSINESS WIRE)--March 12, 1999--CacheFlow(R) Inc., the leader in Internet accelerators, today announced the appointment of Brian NeSmith as chief executive officer.

NeSmith, formerly CEO of Ipsilon Networks and recently vice president of Nokia's IP Routing group, brings 15 years of experience managing high-growth businesses in the networking industry. His arrival underscores CacheFlow's distinction as a networking equipment vendor.

"Accelerating the Internet requires a new generation of network infrastructure technology. Brian understands how to provide leadership in this rapidly emerging market for Internet infrastructure products," said Michael Malcolm, CacheFlow co-founder and chairman of the company's board of directors. In addition to his duties as chairman of the board Malcolm will continue as CacheFlow's technology leader.

As Internet usage continues its exponential growth, organizations with large networks are searching for methods to improve the quality of service for end users.

Service Providers and Enterprises are discovering that the Internet is inherently slow. The slow response times commonly experienced by Internet users are caused by the Internet's latency. Additional bandwidth alone will not conceal this latency. In order to speed Web content to users it must be delivered from a source near them.

CacheFlow was founded specifically to accelerate the Internet. Deployed like routers at the network edge near users, CacheFlow's family of Internet accelerators uses patent-pending algorithms that reduce and conceal Internet latency.

"The opportunity facing us is exciting," said NeSmith. "CacheFlow is the clear technology leader, and our vision and products have been validated by large customers and partners around the world. I am looking forward to leveraging this strong foundation and maximizing our business potential in this billion dollar global market."

Prior to joining CacheFlow, NeSmith was CEO of Ipsilon Networks. With strengths in product strategy and field operations, he led Ipsilon's delivery of the industry's first IP routing switch and quickly grew revenues. After Ipsilon's acquisition by Nokia, NeSmith served as vice president of Nokia's IP routing group.
