Portability experiment for CTRON communication control (transport layer and session layer)

Abstract

In Step2 of the portability experiment conducted by the CTRON Technical Committee, the authors ported CTRON-specification Extended OS (transport layer and session layer communication control programs) developed by each of the participating companies to CTRON-specification Basic OS developed by other firms to run on different hardware. The aim of this experiment is to evaluate the success of CTRON Basic Communication Control specifications. The authors outline this experiment and discuss impediments to porting CTRON Basic Communication Control products. They evaluate the scale of modified lines and the number of man-hours required for the porting process. They also suggest how to solve the problems of porting programs.<>
