GRID-2012, Dubna, Russia 16-20 july 2012

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
