Kalpana was a computer networking equipment manufacturer, located in Silicon Valley[1] and co-founded by Vinod Bhardwaj, an entrepreneur of Indian origin,[2][3] and Larry Blair.[4] during the 1980s and 1990s. They named the company after Bhardwaj's wife, Kalpana, whose name means "imagination" in Sanskrit.[4]

Kalpana is considered to be the inventor of Ethernet switching[1] as the company was the first to introduce the concept of a multi-port network switch with its seven-port EtherSwitch[5] in 1989.[6][7]

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.[1]
