Abstract
Abstract A system for loading a program in a distributed processing system including a plurality of information processing units interconnected by a transmission system. An information processing unit prepares a program and sends the program to the transmission system. Another information processing unit receives the program from the transmission system and stores the program in a memory in accordance with a content code of the program. A program based on program may be retrieved from the memory structural information, and sent to the transmission system. Each information processing unit includes a device for sending program structural information to the transmission system, selecting a corresponding program from the transmission system and loading the selected program in the unit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A method for loading a program in a distributed processing system including a plurality of information processing units interconnected by a transmission system, comprising the steps of: storing at least one program and its identifier in a memory of at least one of said information processing units; transmitting a message from an information processing unit, said message including a request for a program to be loaded into at least one of said information processing units; receiving said message and retrieving at least one stored program and its identifier based on said message from a memory of at least one information processing unit other than said information processing unit sending said message; transmitting said at least one stored program and its identifier retrieved from said memory; and selecting a program on the basis of said identifier from said at least one stored program being transmitted and loading the selected program in a memory of at least one information processing unit other than said information processing unit transmitting said stored program and identifier.
Claim 2
Independent Claim
171 words
A method for loading a program in a distributed processing system including a plurality of information processing units interconnected by a transmission system, comprising the steps of: storing at least one program and its identifier in a memory of at least one of said information processing units; transmitting a message from an information processing unit, said message including a request for a program to be loaded into at least one of said information processing units; receiving said message and retrieving at least one stored program and its identifier based on said message from a memory of at least one information processing unit other than said information processing unit sending said message; transmitting said at least one stored program and its identifier retrieved from said memory; and selecting a program on the basis of said identifier from said at least one stored program being transmitted and loading the selected program in a memory of at least one information processing unit other than said information processing unit transmitting said stored program and identifier.
Claim 3
Dependent Claim
86 words
A method for loading a program according to claim 1 further including the steps of: generating a program in at least one of said information processing units; transmitting said program and its identifier for storing in a memory of at least one information processing units; and receiving said program and its identifier, checking said identifier and storing said program, and its identifier in a memory of at least one information processing unit other than an information processing unit transmitting said program and its identifier for storing.
Claim 4
Dependent Claim
54 words
A method for loading a program according to claim 1, wherein said selecting step includes the steps of: receiving said at last one stored program and its identifier; checking the identifier of said at least one stored program; and storing in a memory a selected program having an identifier corresponding to a specific identifier.
Claim 5
Dependent Claim
38 words
A method for loading a program according to claim 1, wherein each information processing unit at initialization transmits a message which includes a request for a program to be loaded in said information processing unit transmitting said message.
Claim 6
Dependent Claim
131 words
Apparatus for loading a program in a distributed processing comprising: a plurality of information processing units interconnected by a transmission system; wherein each information processing unit of said plurality of information processing units includes means for transmitting a program with a program identifier indicating the content of said program and means for receiving said program checking said program identifier, and storing in a memory a selected program having an identifier corresponding to a specific identifier; and wherein at least one of said information processing units includes means for retrieving a program from a memory based on a program identifier which is included in a request for program loading command transmitted as part of a message from an information processing unit, and means for transmitting said retrieved program with its program identifier.
Claim 7
Dependent Claim
131 words
Apparatus for loading a program in a distributed processing comprising: a plurality of information processing units interconnected by a transmission system; wherein each information processing unit of said plurality of information processing units includes means for transmitting a program with a program identifier indicating the content of said program and means for receiving said program checking said program identifier, and storing in a memory a selected program having an identifier corresponding to a specific identifier; and wherein at least one of said information processing units includes means for retrieving a program from a memory based on a program identifier which is included in a request for program loading command transmitted as part of a message from an information processing unit, and means for transmitting said retrieved program with its program identifier.
Claim 8
Dependent Claim
29 words
Apparatus for loading a program according to claim 5 wherein each information processing unit further comprises means for transmitting a message which includes a request for program loading command.
Claim 9
Dependent Claim
36 words
An apparatus for loading a program according to claim 6 wherein each information processing unit further comprises means for transmitting a message which includes a request for program loading at initialization of said information processing unit.
