Kalpana, Inc., was a computer-networking equipment manufacturer located in Silicon Valley[1] which operated during the early 1990s.

[4] Charles Giancarlo was Kalpana's vice president of products and corporate development, became its General Manager, and went on to roles at Cisco Systems and Silver Lake Partners.

[6][7] Kalpana also invented EtherChannel, which provides higher inter-switch bandwidth by running several links in parallel.

This innovation, more generally called link aggregation, was also widely adopted throughout the industry.

Kalpana also invented the Virtual LAN concept as closed broadcast domains, which was later replaced by 802.1Q.
