Comparison of Software Defined Networking with Traditional Networking

The Internet has caused the advent of a digital society; wherein almost everything is connected and available from any place. Thus, regardless their extensive adoption, traditional IP networks are yet complicated arduous to operate. Therefore, there difficulty in configuring network line with predefined procedures responding load modifications faults through reconfiguring. current likewise vertically incorporated make matters far more complicated: control data planes bundled collectively. Software-Defined Networking (SDN) an emerging concept which aims change this situation by breaking vertical incorporation, promoting logical centralization control, separating logic basic switches routers, enabling programming. segregation concerns identified between policies network, implementation hardware switching forwarding essential flexibility required: SDN makes it less facilitates introduce new concepts networking issue into tractable parts, simplifies management facilitate development network. In paper, reviewed; introduces SDN, explaining its core concepts, how varies networking, architecture principles. Furthermore, we presented crucial advantages challenges focusing on scalability, security, flexibility, performance. Finally, brief conclusion revised.
