   Note that there might be just one SNMP protocol engine and one
   "context resolver" which are accessed by all local management
   applications, or, each management application might have its own SNMP
   protocol engine and its own "context resolver", all of which have
   shared access to the local party database [2].

   In addition to the elements shown in the figure, there would need to
   be an interface for the administrator to access the local party
   database, e.g., for configuring initial information, including
   secrets.  There might also be facilities for different users to have
   different access privileges, and/or other reasons for there to be
   multiple (coordinated) subsets of the local party database.
