The modern telecommunication system is characterized by the rapid improvement\nof information and communication technologies, such as the improvement\nin the data rate, power consumption and Quality of Service (QoS).\nBased on this development, the next generation network (NGN) is shaped.\nThe NGN is represented by a packet transport network demarcated functions\nand services. To provide transport functions in NGN, using Multi-Protocol\nLabel Switching (MPLS) technology, there are two main problems, which are\nmultipath routing and traffic distribution, which are what this paper works\nwith. Accordingly, this paper proposes a solution to these two problems using\noptimization procedures to find the shortest path Dijkstra and Bellman-Ford,\nwhich is characterized by a high-speed-oriented selection of a single shortest\npath between the source and the destination, based on several selected criteria\nrelated to the optimal use of the network resources. Solving the information\nflow distribution problems in large number of nodes network applying salesman\nprocedure or having NP-completeness, causes significant time delay,\nwhich means that the proposed solution is not suitable for real time applications.\nAccordingly, for real time applications, there is a need to move to other\nmethods based on the use of several independent shortest paths.
