“…The controller is the most important and fundamental part of the SDN architecture [36]- [38]. In SDN networks, control is carried out centrally in the controller [39], [40]. Centralized management using the SDN controller greatly simplifies network management by making efficient use of resources using global network information [33].…”

This paper addresses traffic engineering (TE) issues in software-defined vehicular networking (SDVN). A brief analysis of the features of SDVN, which improves the efficiency of TE in SDVN, is presented. The feasibility of using multi-path routing with TE is substantiated. A procedure and an example of the formation of multiple routes based on a modified wave routing algorithm are given. Considering the features of the SDVN technology, a modified TE method is proposed, which reduces both the time complexity of forming multiple paths and the path reconfiguration time. The dynamic path reconfiguration algorithm is presented. INDEX TERMS Intelligent transportation system (ITS), multi-path routing, software-defined network, traffic engineering (TE). I. INTRODUCTION The ever-growing number of vehicles on the roads makes the vehicular ad-hoc network (VANET) an important research topic in the field of automotive and wireless technologies. VANETs are considered as a subclass of classic mobile ad hoc networks (MANETs) [1]-[3]. Where vehicles play the role of mobile nodes of the VANETs. That have embedded advanced equipment on-board, traveling on restricted routes (i.e., roads, streets and lanes), and communicating with each other for information exchange using vehicle-to-vehicle (V2V) communication protocols, and also between vehicles and roadside units (RSU) installed on the side of the roads (i.e., wireless and cellular network infrastructure), to form a link between a Vehicle-to-Infrastructure (V2I). Compared to static or low-speed moving nodes in a traditional wireless network, vehicles move faster and more unpredictably, resulting in frequent changes to VANET network settings [4]-[7]. This places higher demands on routing protocols in VANET networks. Most well-known routing methods are not effective for VANET networks [8]-[11]. In this regard, the urgent The associate editor coordinating the review of this manuscript and approving it for publication was Chao Chen.

“… Best Fit: In which the available bandwidth Chanel that best fit the requirements Taking in account, when DFS method is used to create multiple paths in DCN, the most effective strategy is Worst Fit. Moreover, the efficiency of aeration of many paths using DFS method is increased in association with the peculiarities of the DCN hierarchical organization and the communication channels bandwidth between the nodes of the network [14].…”

“…This paper considers the modeling proposed in article [4] mathematical model of a modernized method of constructing traffic in networked data centers with a branched topology, focused on software configuration of the network. This method, by taking into account the peculiarities of the organization of SDN, in particular due to the presence in the network of a central controller, reduces the time of formation of many routes of access to network resources [5], [6], [7], [8] and [9].…”

This article consider two main local network topologies. Based on the basic DFS protocol, a mathematical model has been developed for a new method of multipath routing and traffic engineering in data centers with a ramified topology. This method was developed with the features and benefits of SDN in mind. Also, the simulation of the developed method was carried out on two local topologies considered earlier.

“…Here in this implementation, though we could test the solution for any number of virtually simulated switches and hosts, we could not verify the solution in a larger physical network; we can check the solution for large physical networks of switches and hosts. Also Virtualization solutions like load balancers and firewalls can be built to make the networks of future more robust, secure [11] and functional.…”

Abstract-Software Defined Networking is a paradigmshifting technology in the field of computer networking. It empowers network administrators by giving them the ability to manage the network services through abstraction of the low-level network functionalities. This technology simplifies networking and makes it programmable. This paper presents an implementation of this new paradigm of networking, which can replace the currently existing legacy networking infrastructure to provide more control over the network, perform a better analysis of the network operation and hence program the network according to the needs of the network administrator. This implementation also empowers the network administrators to provide Quality of Service to its users that are connected to the network and uses the services of the network. Therefore, it benefits both the network administrator and the users. Also, the ping latency in the network is reduced by 5-10%, and the number of packets in is reduced by 60-70% in the solution developed depending on the size of the network.
