The widespread use of computers and commun … The widespread use of computers and communication networks creates a distributed computing environment where there is the demand to build applications with every increasing requirements in what concerns dependability and real-time characteristics. However, this situation induces requirements on the communication subsystems that cannot be easily satisfied by most existing infrastructures without adaptations. These systems are not usually fully synchronous, presenting a high variability in response time that makes it difficult to achieve real-time operation. To improve this situation, we propose the use of the quasi-synchronous approach, where we use a small synchronous part of the system to control and validate the other parts. In the context of this paper, our target communication infrastructure is the ISO 8802/3 LAN (Ethernet), which is a low cost network with a large installed base. Being able to improve the real-time characteristics of such environment offers a very cost-effective solution to a large class of applications. In order to be able to build our proposed architecture in this setting, we introduce some mechanisms to enforce the real-time characteristics of the access control layer. aracteristics of the access control layer.
