Operating the Internet
Each network, be it the ARPAnet, NSFnet or a regional network, has
its own operations center. The ARPAnet is run by BBN, Inc. under
contract from DARPA. Their facility is called the Network Operations
Center or NOC. Cornell University temporarily operates NSFnet
(called the Network Information Service Center, NISC). It goes on to
the
regionals having similar facilities to monitor and keep watch over
the goings on of their portion of the Internet. In addition, they all should
have some knowledge of what is happening to the Internet in total. If a
problem comes up, it is suggested that a campus network liaison should
contact the network operator to which he is directly connected. That is,
if you are connected to a regional network (which is gatewayed to the
NSFnet, which is connected to the ARPAnet...) and have a problem,
you should contact your regional network operations center.
