Abstract
When a problem occurs in communication carried out by a user, information concerning the problem is notified to the user. A network management system transfers a problem notification program to a network device adjacent to a place experiencing the problem. The problem notification program notifies “communication impossible” to a terminal of a transmission source of data output from an output port of the network device.
Claims14
A network system having a plurality of terminal devices and a plurality of network devices for relaying data among said terminal devices, said terminal devices being used by users of said network system, wherein each network devices includes:
- first means for detecting a problem in said network device;
- second means for detecting a terminal device which is a transmission source of data output to an output port of said network device in which said problem has occurred;
- and
- means for notifying problem information representing occurrence of said problem in said network device to said terminal device which is the transmission source of data output to said output port detected by said second means for detecting, thereby informing the user of said terminal device of said problem.
A network system having a plurality of terminal devices, a plurality of network devices for relaying data among said terminal devices and a network management system for managing said network, wherein:
- said network management system includes:
- means for generating a problem notification agent which is movable among devices and whose first moving destination is indicated, and
- means for assigning an output port to be monitored to the agent thus generated, wherein the problem notification agent moved to the network device thus indicated:
- detects a terminal device serving as a transmission source of data output from the output port under monitor which is indicated by the network device concerned;
- and
- notifies problem information representing occurrence of the problem to the terminal device serving as the transmission source thus detected.
A network system having a plurality of terminal devices and a plurality of network devices for relaying data among said terminal devices, said terminal devices being used by users of said network system, wherein each network device includes:
- status monitoring means for detecting a terminal device which is a transmission source of data output from an output port in which a problem has occurred, and generating a problem reception agent in said terminal device which is the transmission source of data output to said output port, said problem reception agent receiving problem information representing the occurrence of the problem from said network device.
A network system comprising a plurality of terminal devices and a plurality of network devices for relaying data among said terminal devices, wherein:
- each of said terminal devices includes problem notification means for generating a search agent which successively moves among network devices on a route directing to a terminal device of a transmission destination of data for which a problem is recognized, and when said search agent cannot move to a next network device on the route directing to the terminal device of the transmission destination of the data concerned, said search agent notifies occurrence of the problem to the terminal device concerned.
A network system including a plurality of terminal devices and a plurality of network devices for relaying data among said terminal devices, wherein each of said network devices has problem notifying means, and
- wherein said problem notifying means of each network device:
- exchanges a message with problem notifying means of another network device which is directly connected to the network device concerned;
- analyzes data output from an output port connected to the other network device to detect a terminal device of a transmission source of the data concerned when a problem occurs in the exchange of the message;
- notifies problem information representing occurrence of the problem to the terminal device of the transmission source thus detected;
- checks, by exchanging a message with a terminal device of a transmission destination of the data, whether communications with the terminal device of the transmission destination of the data are possible after the problem information representing the occurrence of the problem is notified to the terminal device of the transmission source detected;
- and
- notifies restoration of the problem to the terminal device of the transmission source detected if the communications are possible.
A method of notifying problem information to a terminal device in a network system comprising a plurality of terminal devices and a plurality of network devices for relaying data among said terminal devices, said terminal devices being used by users of said network system, in each network device the method comprising the steps of:
- analyzing data output from an output port in which a problem occurs, first detecting a problem in said network device and second detecting a terminal device which is a transmission source of the data output to an output port of said network device in which said problem has occurred based on the data analysis;
- and
- notifying problem information representing occurrence of said problem in said network device to said terminal device which is the transmission source of data output to said output port detected by said analyzing and second detecting steps, thereby informing the user of said terminal device of said problem.
A storage medium for storing a program which is installed and executed in a network device which relays data among a plurality of terminal devices, wherein said program when executed causes said network device to perform the steps of:
- analyzing data output from an output port in which a problem occurs, first detecting a problem in said network device and second detecting a terminal device which is a transmission source of the data output to an output port of said network device in which said problem has occurred based on the data analysis;
- and
- notifying problem information representing occurrence of said problem in said network device to said terminal device which is the transmission source of data output to said output port detected by said analyzing and second detecting steps, thereby informing the user of said terminal device of said problem.
