PURPOSE:To obtain a large-scale distributed computer system excellent in uniqueness, mobile transmission, extension, efficiency, availability and failure-durability by utilizing relative expression and changing the 'expression depending on a used location. CONSTITUTION:In the case a message is delivered by an object C to an object D, '3:2.21.52' which is the object ID(OID) of a receiver is converted into '2.21.52' when it is received by a name space manager having a local object ID (LID) is '12'. Then it is converted into '1:2.21.52', '0:2.21.52','0:21.52', '0:52' and '0' and delivered to the object D, and when it is received by the object D, it is converted into the OID indicating itself. To the contrary, '0:' which is the OID of a transmitter is converted into '3:1.12.41' when it is received by the object D. That is, the expression of the identifier of the object within the system is made based on the relative relationships between the position of the object using the identifier and that of the object indicated by the identifier when it is generated. |
