Method of Distribution Network Resources after Restoration, the Networks MPLS-TE Use of Various Telecommunications Technologies to Construct Backbone Networks

Abstract

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

Review and performance evaluation of FIFO, PQ, CQ, FQ, and WFQ algorithms in multimedia wireless sensor networks

“…In Alhihi et al, 2 a multipath routing algorithm was investigated, then the shortest path was evaluated, and the maximum flow that can meet the required QoS was provided, while in another study by Alhihi et al 3 the performance impact of the routing methods was inspected. A valuable understanding of the routing strategies that is related to the QoS can be gained from Alhihi 4 and the references therein, where a comparative analysis was performed to obtain a satisfactory QoS, unlike the proposed work where a fixed required level of quality is used to determine the easiest service map that controls the queue formation and the transmitted load.…”

A Mathematical Model for Managing the Distribution of Information Flows for MPLS-TE Networks under Critical Conditions

“…In [4], both of multipath routing and traffic distribution were investigated and optimum solution is proposed to find the shortest path using Dijkstra and Bellman-Ford algorithm. Interesting and useful comparative analysis for various routing strategies is produced in [5] with the relative proposed framework models.…”
