A study on the designing f private networks considering response time under packet switching network environment

This paper presents a method for designing private networks considering response time under packet switching network environment Specifically, we propose the designing process of a private network, where the host is assumed to be synchronous and the terminals to be asynchronous, according to protocol and access lines. To calculate the response time for the networks, we use the mutual independent M/M/1 and M/W/s queueing models. Comparing the response time derived from the model with the actual one, it is found that the model yields almost same performance in a more economic way. From the experiment, it is suggested that the necessary number of lines as well as the response time for a specific network can be estimated properly by sensitivity analysis.
