Abstract
Abstract A method and system for generating symmetrical communication interfaces using asymmetrical tools defines two interface definition files. The two interface definition files are compiled by an interface definition compiler to create first role and second role interface files, such as client and server roles for two symmetrical replicas. The first role interface file resulting from the compile of the first interface definition file is discarded, while the second role interface file resulting from the compile of the second interface definition file is also discarded. The first role interface file resulting from the compile of the second interface definition file and the second role interface file resulting from the compile of the first interface definition file are replicated in a plurality of systems coupled to the network. A preferred way of generating a second interface definition file from a first interface definition file is an automatic interface definition file editor which modifies a character string in each function name in the first interface definition file.
