Modeling Resources with Split Ownership and Control

       Fig. 1

      Disclosed is a method for creating an Open Systems
Interconnection (OSI) management model of computer network resources
for which ownership and control are split between two locations.

      In the migration away from hierarchical Systems Network
Architecture (SNA) subarea networks to Advanced Peer to Peer

Networking* (APPN) networks, a method was needed to accommodate the
large existing base of terminal controller equipment and display
terminals that require the subarea SNA services.  Rather than putting
all of the hierarchical SNA support needed for these older devices
into every APPN system, a method was created to extend the reach of
the existing SSCP (system services control point, the host which
controls the older equipment) into the APPN network.  This allows the
older equipment to be attached to the APPN systems and still receive
all the needed services from the SSCP.  Basically, the method
provides a pass through for the SSCP control sessions from the APPN
node to the actual SSCP product.

      So far as network management is concerned, this arrangement has
the advantage that all the existing SSCP-based management tools for
the older equipment will continue to work without modification.  One
problem, however, is that network operators must be aware of the
actual network configuration; otherwise, the terminal equipment will
appear to attach directly to the SSCP host, not to the APPN system
that is providing the actual connection.

      Part of the configuration information is incorporated into the
OSI distinguished name for the managed objects that represent the
terminal controller (called a physical unit, or PU in SNA) and the
terminal displays (called logical units, or LUs in SNA).
Distinguished names are specified by defining a rule for constructing
the names, called a name binding.  The na...
