<p class="Abstract">The production of energy from renewable sources, such as the energy from electricity-water, which reduces the amount of CO2, is called clean energy. Today, technologies and methods that reduce energy consumption in computer networks and Co2 production in the environment are called green networks. Now, high consumption of energy in networks and increasing production of Co2 is an important global challenge. This research analyzes the three important principles of optimization, not draining resources and not wasting resources from green network standards. This research shows that high-performance optimal routing algorithms do not always guarantee green standards in networks, and the principles of optimality and greenness must be combined. Therefore, by combining the principles of being green and the principles of linear optimization, a new green optimal routing algorithm in computer networks is presented. Next, three types of USCP, OUMR and OMMR routing algorithms are analyzed according to green standards and it is proven that they are not green despite being optimal. Then, based on the strengths and weaknesses of these methods, a new green optimal routing algorithm is presented. The simulation results and comparisons show that the new method, while increasing the network efficiency, also improves the green standards of data transmission.</p>
