Comprehensive evaluation of shortest path algorithms and highest bottleneck bandwidth algorithm in software defined networks
MetadataShow full item record
Traditional network architectures are ill-suited to meet the necessities of the present enterprises, carriers, and end users. Hence, new emerging network architecture, Software Defined Network (SDN) can be used to solve the problems since it is more dynamic, manageable, adaptive and programmable. The control and data planes in SDN architecture are decoupled, network intelligence and state are legitimately centralized, and the basic network infrastructure is abstracted from applications. However, a network may reach a point where data flow which is controlled according to the bandwidth is limited by computer or network resources. When bandwidth is unable to accommodate large amounts of system data at designated data transfer rate speeds, it results in bottleneck. We utilized an existing algorithm that can improve network performance by detecting bottlenecks and route packets through the highest bottleneck bandwidth which has been implemented using java programming language. Moreover, although many algorithms have been proposed and used in various applications, a comprehensive evaluation and quantitative comparison of shortest path algorithms in SDN applications is missing. In this paper, we will narrow that gap giving an up-to-date survey of SPF Algorithms in SDN applications.
