Performance Analysis of the Composite Distributed Directories for High Performance Grid Information Services

고성능 자원정보서비스 구축을 위한 복합 모델 기반 분산 디렉토리의 성능 분석

In this paper, we conduct a performance analysis for the composite scheme that is obtained by combining the data distribution and the data replication schemes usually used for the implementation of distributed directory service systems. The analysis results reveal that the composite model is a viable option to overcome the performance trade-off between the data distribution and the data replication model. In this paper, we present the performance model developed for the composite model by appling queuing modelling. Using the performance model, performance values for a variety of system execution environments are suggested which enable us to bring an efficient design for high performance distributed directories.
