| Abstract(in English) | It is an important and urgent tele-traffic issue to evaluate and/or to estimate the delay in a web-server system handing internet commerce real-time services. Usually, multiple proxy servers in differently-located sites (from the web-server site) enable us to shorten the web-server access delay in order to guarantee the quality of real-time application services. However, there exists almost no literature on the access delay analyses for the web-server system with multiple proxy servers. The goal of this paper is to provide an access-delay analysis engine for a web-server system with multiple proxy servers. Our approach is based on the diffusion process technique. We derive the statistics (the squared coefficients of variation) of the individual output processes from the proxy servers. Regarding the unfinished workload in the web-server system with input (which is nothing but the superposition of the output processes from the proxy servers) as a diffusion process, we derive a mean-delay explicit formula. Our formula is shown to be consistent with the previously obtained result for a special case (single proxy server and Poissonian arrival model). |
