Design and Strategy Deployment of SD-WAN Technology: In Indonesia (Case Study: PT. XYZ)

For large companies with branch offices spread across various regions, it is not enough to rely on traditional wide area network (WAN) technology to connect networks between data centers, head offices, and branch offices that are far apart. This is because traditional WAN operation requires many devices with their own complexities. SDN is a method that separates the Control Plane and the Forwarding Plane. In a traditional network, the two functions above are in the same device. One of the SDN technologies on the network is SD-WAN. Another problem in traditional network is WAN infrastructure primarily uses MPLS, which can be very expensive and has limited bandwidth. With the increasing volume of data, MPLS costs can be quite high the expensive cost. PT. XYZ as a banking company that has branches scattered everywhere must pay attention to this. This paper proposes the suitable design and implementation scenario of SD-WAN technology at PT. XYZ so that the existing network can be integrated. From the proposed design, it can be shown that SD-WAN technology is able to answer the weaknesses of traditional WANs in terms of ease of monitoring, cost efficiency, and flexibility
