Network management system capable of easily switching from an active to a backup manager
First Claim
1. A network management system, comprising:
- first through N-th agents, each of which carries out a management operation on a management object, where N represents a predetermined natural number which is not less than two;
an active manager for managing said first through said N-th agents; and
a backup manager for managing said first through said N-th agents, whenever a fault occurs in said active manager, and wherein;
said active manager includes fault detecting means for detecting said fault in said active manager to produce a fault detection signal,said backup manager includes delivering means supplied with said fault detection signal for delivering, in response to said fault detection signal, a name signal representative of a backup manager name, assigned to said backup manager as an indicated name to said first through said N-th agents, andeach of said first through said N-th agents comprising;
storing means for preliminarily storing an active manager name assigned to said active manager as a stored manager name and for storing, as said stored manager name, said indicated name when supplied with said name signal; and
sending means connected to said storing means for sending management information to one of said active and said backup managers which is assigned with said stored manager name.

Abstract
In a network system comprising first through N-th agents, each of which performs a management operation on a management object (N representing a predetermined natural number which is not less than two), an active manager for managing the first through the N-th agents, and a backup manager for managing the first through the N-th agents when a fault occurs in the active manager, the active manager includes a fault detecting unit for detecting the fault in the active manager to produce a fault detection signal. Supplied with the fault detection signal, the backup managing process delivers a name signal representative of a backup manager name assigned to the backup manager as an indicated name to the first through the N-th agents through backup transmitting/receiving unit and the circuit switching device. In each of the first through the N-th agents, an agent process stores, as a stored manager name, the indicated name in a memory unit on reception of the name signal.
