Although officially formed in 1986, ESnet’s roots stretch back to the mid-1970s, when staff at the CTR Computer Center at Lawrence Livermore National Laboratory installed four acoustic modems on a borrowed Control Data Corp. 6600 computer.

Since those days, the network now known as ESnet has marked many milestones and is today one of the world’s premier networks supporting scientific research around the globe.
