           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.
