Performance Evaluation of SD-WAN Deployment for XYZ Enterprise Company in Indonesia

Internet use has been exceptional during the previous several decades. As a result, Wide Area Network (WAN), employed in all types of inter-data center, enterprise, and carrier networks, has become a vital infrastructure since it serves as one of the internet's most crucial transmission mediums. However, due to the transfer of enterprise data to the cloud, internet traffic in the future is changing. As a result, traditional WAN connectivity will be inadequate. One of the viable solutions to this is to implement Software-Defined WAN (SD-WAN) for enterprises, particularly in Business-to-Business (B2B). SD-WAN replaces existing Multi-Protocol Label Switching (MPLS) with multi-broadband internet with high bandwidth, encrypted with Virtual Private Network (VPN) IP Sec standard, and simplifies branch management with a single dashboard covering multiple branches. This study aims to evaluate the performance of deploying SD-WAN on mining enterprises' public links such as Direct Internet Access (DIA), fixed broadband, and 4G LTE, and private links, namely, Very Small Aperture Terminal (VSAT) and Multi-Protocol Layer Switching (MPLS), by utilizing SD-WAN's architecture and scenarios testing with the head office in Jakarta and branch office in Balikpapan. The results obtained that SD-WAN works appropriately when one of the multiple links is down. Meanwhile, when multiple links are down, the SD-WAN can still access a Voice over IP (VoIP) and video conference between the head office in Jakarta and a branch office in Balikpapan.
