웹 서어버를 위한 유사출생사멸 Threshold 대기행렬모형 = A Threshold QBD Queueing Model for Web Server System

다국어 초록 (Multilingual Abstract)

This paper proposes queueing models for a Web server system which is composed of an infinite-buffer main server and finite-buffer auxiliary server(s). The system is modeled by the level-dependent quasi-birth- death (QBD) process. Utilizing the special structure of the QBD, we convert the infinite level-dependent QBD into a finite level-independent QBD and compute the state probabilities. We then explore the operational characteristics of the proposed web-server models and draw some useful conclusions.
