Abstract

This paper makes two contributions to the study of configuring real-time aspects into quality of service (QoS)-enabled component middleware for distributed real-time and embedded (DRE) systems. First, it compares and contrasts the integration of real-time aspects into DRE systems using conventional QoS-enabled distributed object computing (DOC) middleware versus QoS-enabled component middleware. Second, it presents experiments that evaluate real-time aspects configured in The ACE ORB (TAO) versus in the Component-Integrated ACE ORB (CIAO). Our results show that QoS-enabled component middleware can offer real-time performance that is comparable to DOC middleware, while giving greater flexibility to compose and configure key DRE system aspects.
