RFC 15:Network Subsystem for Time Sharing Hosts
RFC-Ref

2. System Primitives

   G. Deloche of U.C.L.A. has documented a proposed set of basic network
   primitives for inclusion in the operating systems of the respective
   HOSTs (NWG Note:  11).  The primitives are:

      Open primary connection

      Open auxiliary connection

      Transmit over connection

      Close connection.

   The details  and terminology are defined by Deloche and others in
   previous memos.  The primitives are system calls, available to
   programmers, and are most likely a part of the resident monitor,
   rather than the swappable executive.
