Abstract

Disclosed is a method for creating a standard format Directory Information Base (DIB) containing information on all nodes in a computer network to which a specific node may connect. With a standard DIB, communication on the network between communication products supplied by different vendors, using the same communication protocol, can be done without having to manually create a vendor-specific directory for each node supplied by a different vendor. As well, different communication products on the same node can share a common directory source file.

Standardized Network Directory Information Base

      Disclosed is a method for creating a standard format
Directory Information Base (DIB) containing information on all nodes
in a computer network to which a specific node may connect. With a
standard DIB, communication on the network between communication
products supplied by different vendors, using the same communication
protocol, can be done without having to manually create a
vendor-specific directory for each node supplied by a different
vendor.  As well, different communication products on the same node
can share a common directory source file.

      The method disclosed consists of three logical components:
      1.   A source and a target DIB
      2.   A DIB description language (DDL)
      3.   A DDL compiler

      The DDL syntax is specified by a formal, context-free grammar
based on the Backus-Naur form. It provides a format with which to
define DIB entries in a DIB source file in an unambiguous way.

      The DIB source file contains text, in the format specified by
the DDL, which describes the DIB entries. This file can be created or
modified using a text editor.  The compiler parses the DIB source
file, transforms the information as required, and produces the DIB
target file. The target DIB file is actually the file which is used
by the communication software. This file can be as product-specific
as needed since it is used only by the communication software for
which...
