Automated synthesis of protocol specifications with message collisions and verification of timeliness
Yoshiaki Kakuda, Hideji Igarashi, Tohru Kikuno · 2002
Protocol synthesis is used to derive a protocol specification based on a service specification. In the previous protocol synthesis methods, if the service specification includes simultaneous transmission of primitives, then the derived protocol specification includes protocol errors of unspecified receptions caused by message collisions. This paper extends a class of derived protocol specifications to include message collisions which often happen in real communication protocols, and proposes a protocol synthesis method such that (1) simultaneous transmission of primitives causing message collisions can be described in the service specifications, and (2) transitions for avoiding protocol errors of unspecified receptions can be generated by new transition synthesis rates. This paper also proposes a verification method for determining a real-time bound in the synthesized protocol specification using the task scheduling algorithm for multiprocessor systems.>
