Abstract
In article the list of basic data which are reasonable for using for creation of a multiservice communication network packet switched is formulated. It is offered to consider a multiservice communication network as set of the subnets making it, each of which has the functional purpose and architecture. For an access network, network of aggregation, a transport network, network of switching systems, network of management, network of ensuring functioning and network of collecting and information analysis of a status options of rational structures taking into account technical features of providing infocommunication services and management are considered by them which use in total allows to execute synthesis of the corresponding subnets and their mutual accession or imposing. The rational approaches, ways and methods of synthesis of subnets of a multiservice communication network having required values of stability, safety and reliability of functioning are considered and sentences on their achievement are formulated. The technique of synthesis of a multiservice communication network in the course of execution of which on the basis of a method of consecutive concessions is offered rational structures of subnets of its components are synthesized. The offered technique of a solution of a problem of synthesis of MCCC as the sequence of the actions making it is not strict, and does not define a direct execution order of these actions. At the same time, it sets the possible directions of a chain of reasoning in order that taking into account, first of all, the formalized and not formalizable tasks facing a multiservice communication network according to the set criteria, became possible to find the conscious, compromise and acceptable by a number of criteria solution taking into account the price of concessions in some criteria and (or) prize values at the expense of these concessions in other criteria and (or) their ratios. Further, on the basis of the analysis of results and the gained experience in a solution of similar tasks, this technique can be formalized and automated by certain templates with use of methods of representation and knowledge deployment, methods of artificial intelligence, methods of a fuzzy logic or other methods.

Keywords: multiservice communication network, methodic of structural and parametric synthesis, minimum spanning tree.
