Abstract

In each of the information processing apparatuses connected to each other via a network, there is arranged a quality of service (QOS) table to which functions and performance thereof are registered. When an information processing apparatus is additionally linked with the network, a QOS table thereof is automatically registered to a local directory of the network such that an agent converts the contents of the QOS table into service information to be supplied via a user interface to the user. Thanks to the operation, information of functions and performance of each information processing apparatus connected to the network is converted into service information for the user. Consequently, the user can much more directly receive necessary services.

Claims

1. An information processing system, comprising:

a plurality of information processing apparatuses each having a QOS table to which information of functions and performance is registered;

a network for connecting the plural information processing apparatuses to each other;

a local directory connected to the network for controlling a plurality of QOS tables in a unit of local areas, the local areas being a set of small-sized areas;

a global directory for controlling a plurality of local directories in a global area of the unit of local areas; and

an agent function operable in either one of the information processing apparatuses for referencing the respective contents of the global and local directories and converting the information of functions and performance registered to the QOS table into service information representing quality of service, thereby supplying a user with the obtained service information,

wherein the agent function includes;

a terminal agent which is in charge of a client'"'"'s interface to be used by each user and which provides the user and thereby supplying the service information representing quality of services that are common among individual users; and

a personal agent which makes inquiries of said global and local directories about the functions and performances of each apparatus connected to the client server system, converts the functions and performances obtained as a result of the inquiries to service information required by the user, and supplies the user with said service information.

2. An information processing system according to claim 1, wherein the agent function includes an operation reading contents of the plural QOS tables registered to the local directory, detecting a plurality of common functions registered to the QOS tables, and creating a service menu therefrom.

3. An information processing system according to claim 2, wherein the agent function further includes an operation generating a QOS menu for each of the services and supplying the user with the QOS menu.

4. An information processing system according to claim 1, wherein the QOS table includes, as information of functions and performance of the information processing apparatus, either one of a response time, a processing performance per unitary time, and a transfer speed.

5. An information processing system according to claim 1,

wherein the obtained service information is supplied to the user via a user interface, and

wherein the agent function changes, according to a utilization frequency of each service of the user and the contents of the utilization of the services, the contents of the service information supplied to the user via the user interface.

6. An information processing system according to claim 5, wherein the personal agent service resides in a client which is a piece of terminal equipment in any one of the plural information processing apparatuses and a copy of the personal agent service is arranged in a server which achieves a control operation in the plurality of information processing apparatuses.

7. An information processing system according to claim 5, wherein the agent function in the information processing apparatus includes an operation monitoring a state of each application software initiated by each user and changing, according to a state of operation of the application software, the contents of the service information supplied to the user via the user interface.

8. An information processing system according to claim 1,

wherein a service is supplied by the steps of:

referencing, in the agent function of any desired one of the apparatuses, the contents of the QOS tables of the plural apparatuses connected to the network; and

converting the information of functions and performance of the apparatuses registered to the QOS tables into service information representing quality of service, thereby supplying the user with the obtained service information.

9. An information processing system, comprising:

a plurality of information processing apparatuses each having a QOS table to which information of functions and performance is registered;

a network for connecting the plural information processing apparatuses to each other;

a local directory connected to the network for controlling a plurality of QOS tables in a unit of local areas, the local areas being a set of small-sized areas;

a global directory for controlling a plurality of local directories in a global area of the unit of local areas and receiving, when contents of one of the plurality of local directories is changed, a notification of the change in the contents from said one of the plurality of local directories;

an agent function operable in either one of the information processing apparatuses for supplying a user with the information of functions and performance of said one of the plurality of information processing apparatuses, wherein;

a terminal agent which is in charge of a client'"'"'s interface to be used by each user and which provides the user with display of functions that are common among individual users and with presentation of services that are common among individual users; and

a personal agent which inquiries of said global and local directories about functions and performances that each apparatus connected to CSS (client server system) has converts the functions and performances obtained as a result of the inquiry to service information required by the user, and supplies the user with said service information;

the agent function modifies, according to the change in the contents of the global directory, the contents of the service information to supplied to the user.

10. An information processing system according to claim 9, wherein the local directory reads, when an information processing apparatus is connected to the network, a QOS table of said apparatus and registers the QOS table to the system.

11. An information processing system according to claim 9, wherein the local directory deletes, when one of the information processing apparatuses is disconnected from the network, the QOS table of said disconnected apparatus.

12. An information processing system, comprising:

a plurality of information processing apparatuses each having a QOS table to which information of functions and performance is registered; and

a network for connecting the plural information processing apparatuses to each other;

wherein

a terminal agent which is in charge of a client'"'"'s interface to be used by each user and which provides the user with display of functions that are common among individual users and with presentation of services that are common among individual users; and

a personal agent which inquiries of said global and local directories about functions and performances that each apparatus connected to CSS (client server system) has converts the functions and performances obtained as a result of the inquiry to service information required by the user, and supplies the user with said service information;

any desired one of the information processing apparatuses includes an agent function for referencing contents of the QOS tables of the plural apparatuses connected to the network and converting the information of functions and performance of the apparatuses registered to the QOS tables into service information representing quality of service, thereby supplying a user with the obtained service information.
