OSPF is a very important internal entryway protocol that employed in web layer of TCP/IP model and in network layer in OSI model. OSPF is employed in application of current networks like impromptu wireless and mobile communication systems, in ISP, enterprise networks in colleges, hospitals…etc. it additionally employed in management plane of SDN. OSPF can management on call of that have the shortest path of network branches looking on their weights. Principle work of OSPF protocol verify the shortest path by checking link state of network. Also, principle of this protocol, it divides identical network into areas (sub networks).during this paper, OSPF network has one space referred to as (area 0), that has 6-Routers distributed among cities on Iraq’s map. MATLAB (2017b) and GNS-3 (2.1.3) softwares area unit wont to calculate theoretical and experimental results severally. The results evidenced that the most effective path that has the low weights and time period. These results additionally evidenced that if the shortest path is down, it may be used the opposite link (back up) within the network.

Value stream mapping (VSM) applies to all consumer operations engaged in the design, production and distribution of products and services. Objective of this research is to draw up the existing state diagram for the products in Heavy Engineering Equipment State Company (HEESCO) as a case study, that deals with job-shop production to Identify and minimize the additional tasks that are not appreciated and recommend a potential state to reduce the lead time of production and maximize the time of value added.

This paper aims at studying the feasibility of a new approach for teaching the dynamics course, which is usually taught in the sophomore year of engineering curriculum. The new proposed approach is an integrated one, which will be designed to offer the general concept from which the special cases are easily addressed. The concept of rigid body dynamics will be first introduced as the general theory. Particle dynamics is then shown to be a special case of rigid body dynamics.

Specialized commercial software packages have been developed and used in the world, which make it possible to obtain data on the thermophysical properties for certain classes of substances and materials. The experience of the practical use of such programs revealed their significant shortcomings. They do not provide access to the tables of primary experimental data, do not allow to select models for their processing, the models used are not physically sound, which does not allow extrapolation of data, there is no real possibility to predict properties, etc. In Russia, this direction has not yet received a noticeable spread. The Institute of Computational Technologies of the Siberian Branch of the Russian Academy of Sciences in cooperation with the Institute of Thermal Physics of the Siberian Branch of the Russian Academy of Sciences have developed the Information Computing System http://tick2.ict.sbras.ru/, which will allow to combine the advantages of existing codes and eliminate the above disadvantages. The created resource will become an important tool for the development of theories of substance properties and phase transformations.
