Program toolkit NetMax is created for modeling of telecommunication networks for the maximization of the general traffic, and also for the analysis of telecommunication networks.
The analysis technique of the telecommunication networks, loading of networks revealing direct dependence on routing strategy is implemented.
NetMax project
Primary goals
The primary goals which can be solved:Check of efficiency of strategy of routing;Determination of vulnerabilities in a
telecommunication network; Modeling on a failure for determination of
reliability of corporate networks; Execution of an estimation and the
comparative analysis of various strategies of routing;
Visualization of network graph.
NetMax use
Routing in SDH/SONET networks; Management of flows in the distributed
systems of storage and data transmission; Problem of minimization of jams in a city
road network; Problem of development of a city road
network; Routing and planning in IP-networks for
autonomous system or its segments at use MPLS and tunneling;
Channel routing with the centralized management.

Matlab for software development Software Matlab (MATrix LABoratory) is a package of applied
programs for mathematical and engineering calculations includes an internal programming language.
At the moment Matlab use more than 1 million engineers and scientists. (according to Mathworks)
Use of Matlab allows to carry out development of programs quickly
the internal Matlab language is a higher-level programming language,
there is an integrated environment of development, there are many functions and sets of ready subprogrammes
(Matlab toolboxes).
Precompiled application execute at computer possible without installation of Matlab software, but Matlab Compiler Runtime (MCR) – must be installed
