A Programmable and Managed Software Defined Network

Abstract

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.

Intelligent Traffic Engineering in Software-Defined Vehicular Networking Based on Multi-Path Routing

“…Compared to the distributed methods of traffic construction and its balancing, the centralized method eliminates the need for the exchange of service information between network switches. This allows you to reduce the delay by about 5-10%, and the number of control packets in the network is reduced by 60-70% [42].…”

Modified Method of Traffic Engineering in DCN with a Ramified Topology

“…This method can be used for different types of metrics. In the model used, the speed of information transmission along the route is used as a metric, so the controller will choose the path at high speed and send it to the first vertex along the route to the router [11].…”

Certain Contributions in Traffic Engineering Based on Software-Defined Networking Technology

“…To solve these problems, the technology of Software-Defined Networks (SDN) is currently used (Isong et al, 2017;Kumar et al, 2017;Sahoo et al, 2017). A distinctive feature of Software-Defined Networks is that the network is organized and managed at the software level with the use of virtual switches and a central SDN controller (Shu et al, 2016) Fig.…”
