Abstract

A computer system executes a procedure by which a service broker accepts registration of interactive service; executes a procedure by which the service broker accepts a request from a client terminal to provide the interactive service; executes a procedure by which the service broker selects servers allowed to provide resources requested by the interactive service as candidates for the destination of arrangement of the interactive service; executes a procedure by which the service broker specifies a server as the destination of arrangement of the interactive service from the candidates for the destination of arrangement on the basis of the provision quality of the interactive service between each server and the client terminal; and executes a procedure by which the service broker arranges the interactive service stored in a memory, in the specified server.

Claims

1. A method of arranging interactive service by a interactive service system including a service broker, severs, and client terminals, said service broker being provided for arranging said interactive service in said servers, said servers being provided for executing said interactive service for said client terminals, each of said service broker and said servers at least having a memory as a storage region used for performing an arithmetic process, and a processor for performing said arithmetic process, said method comprising the steps of:

executing a procedure by which said service broker accepts registration of said interactive service;

executing a procedure by which said service broker accepts a request from one of said client terminals to provide said interactive service;

executing a procedure by which said service broker selects servers allowed to provide resources requested by said interactive service as candidates for the destination of arrangement of said interactive service;

executing a procedure by which said service broker specifies a server as the destination of arrangement of said interactive service from said candidates for the destination of arrangement on the basis of the provision quality of said interactive service between each server and said client terminal; and

executing a procedure by which said service broker arranges said interactive service stored in said memory, in said specified server.

2. A method of arranging interactive service according to claim 1, wherein the provision quality of said interactive service is the communication quality of a network between each server and said client terminal.

3. A method of arranging interactive service according to claim 1, wherein the provision quality of said interactive service is calculated on the basis of the frequency in use of said interactive service between each server and said client terminal.

4. A method of arranging interactive service according to claim 1, further comprising the steps of:

executing a procedure by which said service broker receives a notification of the provision quality of said interactive service arranged by said service broker and being running between said service broker and said client terminal; and

executing a procedure by which said service broker rearranges the arranged interactive service in another server than the server concerning said notification when the provision quality of said interactive service due to said notification does not satisfy a predetermined quality.

5. A method of arranging interactive service according to claim 1, wherein said procedure for selecting candidates for the destination of arrangement of said interactive service is a procedure by which servers are selected as candidates for the designation of arrangement so that a fee related to each of the servers is not larger than an allowable maximum fee related to said interactive service.

6. A method of arranging interactive service according to claim 1, wherein said procedure for arranging said interactive service stored in said memory, in said specified server is a procedure by which said service broker registers the address and name of said specified server in a corresponding name server.

7. A method of arranging interactive service according to claim 1, wherein said interactive service system is configured so that said service broker and said servers are stored in one box.

8. A program of arranging interactive service, wherein a method of arranging interactive service as defined in claim 1 is executed by a computer.

9. A recording medium in which a program defined in claim 8 is recorded so that said program can be read from said recording medium by a computer.

10. A service broker in a interactive service system including said service broker, servers, and client terminals, said service broker being provided for arranging interactive service in said servers, said servers being provided for executing said interactive service for said client terminals, said service broker comprising a memory as a storage region used for performing an arithmetic process, and a processor for performing said arithmetic process, wherein:

said memory is used for recording an execution program of said interactive service, information of resources requested by said interactive service at the time of execution, the destination of arrangement of said interactive service and the quality provided by said interactive service; and

said processor includes a interactive service arrangement portion for selecting servers allowed to provide resources requested by said interactive service as candidates for the destination of arrangement of said interactive service and specifying a server as the destination of arrangement of said interactive service from said candidates for the destination of arrangement on the basis of the provision quality of said interactive service between each server and the client terminal as a requester.

11. A service broker according to claim 10, wherein said processor further includes a interactive service rearrangement portion for rearranging the arranged interactive service in another server than the server concerning a notification of the provision quality of said interactive service when the provision quality of said interactive service received as said notification from the server does not satisfy a predetermined quality.
