Method for changing non-leaf entry in tree structure of OSI directory information by sequentially issuing OSI directory commands for the non- leaf entry and lower entries associated therewith in response to decoded change command

摘要

A method for changing an OSI (Open Systems Interconnection) directory information including a plurality of entries of a tree structure includes the steps of decoding a change command for changing a portion of the directory information including a non-leaf entry and at least one lower entry associated with the non-leaf entry, sequentially issuing, in response to the decoded change command, OSI directory commands for the non-leaf entry and the at least one lower entry, the issued OSI directory commands being determined based on the decoded change command, and executing the issued OSI directory commands to change the tree structure of the directory information.
