The analysis of existent methods of synthesis of structures of corporate multiservice networks is conducted. Within the framework of analysis of coherent fragments of corporate multiservice networks the concept of informative and technical structures is certain fragment. The synthesis of informative structure of fragment is considered as a process of search of variant of reflection of canonical structure in informative, which is optimum from point of the set criterion of efficiency and satisfies the basic requirements, by the produced application software. A mathematical model which allows to find the optimum variant of such reflection is built.
