Kalpana was a computer networking equipment manufacturer, located in Silicon Valley during the 1980s and 1990s.
Kalpana is considered to be the inventor of Ethernet switching as the company was the first to introduce the concept of a multi-port network switch with its seven-port EtherSwitch in 1989. Kalpana also invented EtherChannel, a technology which provides additional inter-switch bandwidth by running several links in parallel. Kalpana was acquired by Cisco Systems in 1994.
Kalpana had been co-founded by Vinod Bhardwaj, an entrepreneur of Indian origin, and Larry Blair.
They named the company after Bhardwaj's wife, Kalpana, whose name means "imagination" in Hindi.
