Survey of optimizing dynamic virtual local area network algorithm for software-defined wide area network

Software-defined network (SDN) is one of the most predominant technologies for networking in existing and next-generation networks. Therefore, this paper conducted to introduce a survey researchers who are interested exploiting dynamic tunneling technique optimize software-defined wide area (SD-WAN). The main purpose not only investigate related works with SD-WAN but also classify work according aim each research into practicable categories present dominated employments SD-WAN, specifically virtual local (VLAN). performed classification accompany SDN can be summarized four as following: exploring VLAN SDN; management multi recover link failure development by using VLAN. Finally, intensive study literature discovers that dominant path falls class covers SDN’s failure. This takes full advantage SD-WANs due offering more robust restoring communication failures. In event fault, controller could respond quickly switching pre-computed backup route.
