Component composition tools: Process call scheduling according to the priority in connector

Abstract

Component composition and operation constitute the basic structure of system development in CBD, and the component composition technique based on software architecture represents the specification and operation technique for composition. But the existing component composition techniques handle the request of linked component with FIFO method. The method such as FIFO that handles the request of the component just according to the requested order causes the inefficient operation of whole connected components. Thus, the allocated request process according to the priority considering the characteristics of each call components in connector is necessary to improve the operation of assembled component. In this research, the connector has been extended to carry out the request of component with the priority considering the operation characteristic of component specification. We used Wright specification as component composition method and extended the connector part of Wright to be applied to multiple linking structure. Also, the bean request processing time and the memory use rate that directly affect the service efficiency have been considered as main operation characteristics of applied components. Results of this research show that the number of component handled per unit time and the processing waiting time of component have been improved. © Springer-Verlag Berlin Heidelberg 2004.
