In this paper, the author examines a set of modern communication technologies that are or possibly can be used to build communication links between the subsystems of a distributed embedded system. An investigation of these guidelines results in a model for analysis of specific use cases of target technologies. An algorithm for choosing a precise set of factors for the main analysis model is presented too. The goal of the paper is to build a mathematical base for the author's research on comparison of communication technologies. The author describes the principles of both models and presents the results of the test calculations. Practical implementation of target technologies and empirical experiment data are based on a practical experience during the design and test of specific distributed systems in different markets.
