Congratulations to our colleagues at ESnet on 25 successful years of advanced networking leadership.  Beginning in 1986, ESnet was created to provide high performance networking computing for DOE science researchers.  ESnet enables scientists from 40 DOE sites around the country to connect and collaborate with one another and with research locations around the world to advance scientific discovery.  Because of ESnet and its peers, the development of major science research facilities such as the Large Hadron Collider is made possible. The network supports research in the areas of fusion energy, climate, combustion, genomics and astrophysics by facilitating communications among on-going experiments and transmission of data to the front-line application scientists around the world. In 2011, the network carried 7 petabytes of data per month.  By 2015 it is expected that it will carry more than 100 petabytes of data per month.  To accommodate this data growth, ESnet is developing world’s first 100Gbps nationwide network dedicated to science.  For more on ESnet’s 25^th anniversary and live demonstrations of its 100Gbps network at SC11 see http://www.es.net/news-and-publications/esnet-news/2011/esnet-celebrates-25th-anniversary-at-sc11/.
