This research began when observations were made on any-to-any-connection services that require QoS (Quality of Service) and tunnel measurements. Tunnel is a technique to interconnect between local networks that are separated through a public network. Research questions found looping caused by traffic issues when sending data in the MPLS service layer-2 tunneling service. Furthermore, this research hypothesis proposes optimizing QoS performance in the application of the SR-TE (Segment Routing-Traffic Engineering) method in the MPLS (Multi-Protocol Label Switching) network and analyzing traffic based on MAC addresses using the looping-protection method. This research contributes to optimizing the MPLS network and is a recommended solution for simplifying control-plane operation, especially the SR-TE method and looping-protection in the L2- VPN MPLS service. The purpose of this study is to analyze the performance of MPLS networks, as well as analyze the application of L2-VPN (Layer 2 Virtual Private Network) MPLS networks. The targeted TKT (Technology Readiness Level) is 3rd-Level, which is an analytical and experimental proof of the MPLS tunnel network model on Layer-2 VPN services. The results of the research concluded that testing the SR-TE method is a solution to simplify the process of labeling data traffic that is global labelling, then the looping-protection method is a solution to eliminate looping indications. The QoS obtained has also shown an "excellent" category based on TIPHON standards.
