Method and apparatus for detecting faults in a computer network
TLDR
In this paper, a fault detecting system for a computer network comprising a plurality of computer systems which are placed apart and interconnected by a communication network, and a central computer system monitors faults in the network.Abstract:
The present invention is for a fault detecting system for a computer network comprising a plurality of computer systems which are placed apart and interconnected by a communication network, and a central computer system monitors faults in the network. The central computer system stores fault information which is transmitted from a plurality of computer systems and judges whether the information indicates a fault occurring for a slight fault or for a serious fault based on the length of the duration of the fault, and display means performs the alarm display for a case of a serious fault and does not display for a case of a slight fault. As a result, the central computer system effectively detects faults in a computer network in which a plurality of computer systems are interconnected with the central computer system by means of a monitoring system that automatically distinguishes serious faults from slight faults.read more

Method for providing a fault tolerant network using distributed server processes to remap clustered network resources to other servers during server failure
TL;DR: In this paper, the authors propose a replicated network directory database that operates in conjunction with server resident processes to remap a network resource in the event of a server failure, and this remapping occurs transparently to whichever user/client is accessing the network resource.
Patent
System for clustering software applications
TL;DR: In this paper, the authors propose a fault tolerant execution of an application program in a server network, which includes: a first server for executing the application program; a cluster network database coupled to the first server; an object, stored in the cluster database, which represents the program and contains information pertaining to the program.
