Ipsilon Networks was a computer networking company which specialised in IP switching. The company was important in the introduction of label switching and published early proposals related to the subject. Label switching, known by Cisco Systems as tag switching at the time, was a technology which eventually became standardised as MPLS. The company did not manage to achieve the market share hoped for and was purchased for $120 million by Nokia in 1997.
