Due to sharp growth of information sources from time to time a demand arises to upgrade a network of the tributaries based on synchronous digital hierarchy (SDH) thereby increasing its capacity. At the heart of an offered upgrading technique lies the method of expert evaluations, and the developed software complex serves as the tool for obtaining characteristics of a network. The complex allows us to analyse rather large number of options, being unevident even for some technical specialists owing to rather large amount of works in a network for their introduction. Approbation of the technique and complex showed their efficiency.
