            Sesquinet is a regional network in Texas.  It was  organized
            in  1986  specifically  to  fill  the  regional network role
            within the NSFnet scheme.  It has been operational since May
            1987.

            Sesquinet is primarily an IP network, and connects  directly
            to the NSFnet backbone via an NSS at Rice University.

            In cooperation with THEnet we also carry intra-state  DECnet
            Phase IV that can be passed to SPAN/HEPnet.

            Our original and slowest lines are 56kb/s, and these  remain
            the  normative circuit technology for access from individual
            sites.  We are deploying T1 circuits in two ways:

            o+    In cooperation with THEnet, we are building  an  inter-
                 city  redundant  high-speed  backbone.  Initially, this
                 will be a T1 triangle connecting Houston (Rice  Univer-
                 sity),  Austin (the University of Texas at Austin), and
                 Dallas (the University of Texas at Dallas).

            o+    In addition, some individual  sites  are  connected  to
                 this  intercity  backbone  via T1 circuits.  The Baylor
                 College of Medicine is the first to do so.

            Throughout this network, cisco gateways are used.

            Current  members  include  universities  (e.g.,  Rice,   the
            University  of  Houston,  Texas  A&M  University,  and Texas
            Southern University were charter members), research  labora-
            tories  (e.g., the Southwest Research Institute), and indus-
            trial organizations (e.g., Rockwell International).

            Any of the members  can  exchange  traffic  with  any  other
            member  for  any  purpose.   Any  member  may use any of the
            long-haul networks Sesquinet  has  connections  to,  subject
            only  to the restrictions of the owner of the long-haul net-
            work.
