Kalpana Inc, October 1994
About a year after acquiring Crescendo, Cisco dropped another $200 million on Kalpana, which many at the time considered the leader in Ethernet switching. Kalpana was the first vendor to introduce a multi-port network switch with the release of its EtherSwitch, which featured a whopping seven ports, in 1989. The product line acquired from Kalpana led to the Catalyst 3000 stackable portfolio. Kalpana was also responsible for EtherChannel, a proprietary method of aggregating multiple ports together. This was the one of the first of many proprietary standards that Cisco used to make the end-to-end Cisco network easier to manage than its competitors' products. Kalpana was also the company that brought the brilliant Charlie Giancarlo into the Cisco fold.
