A network management system which includes a plurality of network devices operating in a coordinated manner and a management server managing the network devices. The management server includes apparatus for defining policy information and for generating setup information using policy information to generate setup information for each network device. The system generates setup information for each network device, distributes setup information to each network device, installs setup information to each network device, enables settings, collects setup information for each network device, and organizes and checks for consistency in the collected information.

Network management system for generating setup information for a plurality of devices based on common meta-level information

In view of providing a network system enabling communication having passed fire walls (repeaters) and assuring high security and operation flexibility through access control based on users and applications, a user-held table indicating correspondence between repeaters and passwords, a repeater-held table indicating correspondence between users and passwords and a table indicating access regions are defined respectively for users, departments of users and official positions of users and a route control information storing table indicating correspondence between networks and next transmitting destination is also provided to execute the access control for each user. Moreover, the repeater is provided with the repeating route control table so that a repeater located in the course of route to the transmitting destination computer and allowing communication from the transmitting side computer is selected from the data repeating control table and the process for requesting the repeating operation of communication with the destination is executed to the selected repeater.
