Architecture of Software Defined Wide-Area Network: A Review

The SD-WAN is network architecture of the virtual wide-area system which provides facility to network services to better invest in broadband, LTE, MPLS internet services included in the transport services. This paper consists of full analysis review of SD-WAN and its logical architecture for further development according to the new generation internet demands. During analysis of existing architectures many limitations were found like existing architecture of wan is no more capable to provide high performance with the massive bandwidth of data being on websites, full edge functionalities of data servers and network services. Newly developed advanced applications and with new upgraded technology has inflated the requirements of the long-distance data transmission, which leads to redesigning the wide-area network with a newly designed structure and perspectives which accomplishes the network demands. Some good features also identified like some of the vulnerabilities that can be possible to obtain the information of the version of operating system, version of web server, and type of device which can be used to detect vulnerabilities in the network device.
