AI Technical Summary

Benefits of technology

The system efficiently manages changes to network resources and enables secure, wide-range information retrieval by automatically updating connection information and authenticating users, ensuring proper access and maintaining directory service consistency across interconnected service spaces.

Problems solved by technology

The foregoing conventional techniques, however, have the following problem.
However, the management of the directory service corresponding to those changes is carried out manually, which is quite bothersome.
Accordingly, without recognizing the hierarchy structure between the directories, the proper retrieval can not be achieved.
The conventional directory service protocols are not provided with a function satisfying such a requirement.

first embodiment

Effect of First Embodiment

[0093]As described above, the service object managing mechanisms managing the object repositories storing the service objects and the service space connection managing mechanisms exchange the mutual connection information via the message communication, respectively, so that the relations and states of the distributed service spaces connected by the network are constantly reflected on the system. Thus, in the network environment wherein registration, update and deletion are constantly carried out, the directory service efficiently dealing with changes of the service objects can be provided.

[0094]Further, using the information stored in the service space connection managing mechanisms, the retrieval message can be sent beyond the service spaces so that the wide range of information collection can be automatically achieved.

Second Embodiment

[0095]In this embodiment, an authentication mechanism is provided for allowing only those users having access rights to re...

second embodiment

Effect of Second Embodiment

[0115]As described above, by adding the directory managing authentication mechanisms to the system of the first preferred embodiment, the encryption and authentication of the message can be accomplished using public and secret keys so that the mutual connection information can be managed safely and reliably. Further, in the service object retrieval, only such a user having permission is allowed to search the corresponding service space. Thus, the retrieval can be executed safely and efficiently with the assistance of the highly reliable security arrangement.

[0116]In the foregoing preferred embodiments, the respective mechanisms are realized using the object expression in the Java environment, but may also be realized in the environment of another object oriented language such as the C++ language. Further, in the foregoing preferred embodiments, the object repository is used for storing the service objects. On the other hand, it may also be arranged that th...

Abstract

A distributed directory management system includes a plurality of service spaces on a network each having an object repository storing service objects to be retrieved and attribute information pieces thereof. A service object managing mechanism for each service space manages the object repository and executes retrieval of a service object using the attribute information piece as a key. A service space connection managing mechanism for each service space implements message communication with the service object managing mechanisms to collect mutual connection information of the service spaces and manages the collected mutual connection information. A service object retrieval managing mechanism for each service space sends a retrieval message from a user to the service object managing mechanism in the same service space to request execution of retrieval of a service object. Upon failure in retrieval, the service object retrieval managing mechanism requests another service object managing mechanism to execute retrieval of the service object.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a distributed directory management system which enables retrieval and management of various service objects while coping with changes of a network structure in a complicated network environment such as a large scale intranet or the Internet.[0003]2. Description of the Related Art[0004]For retrieving various information in a complicated network environment such as a large scale intranet or the Internet, a system is necessary for managing and accessing the information. This system is called a directory management system, and there are directory services for offering such a system to users. As examples of the directory services, there are known the “hosts” file and the DNS (domain name system) for recording and managing the correspondence between host names and IP addresses in the TCP / IP network. These are a kind of database files with a name managing function.[0005]There is available anoth...
