Abstract Multiprotocol Label Switching (MPLS) is a versatile network technology that enhances the performance, reliability, and scalability of data traffic management. This article explores a case study of MPLS, detailing its architecture and key components, such as Provider Edge (PE) Routers and Provider (P) Routers. It highlights the benefits of MPLS including simplified connectivity deployment, protocol efficiency, and improved performance. Through practical analysis and examples, this content provides a comprehensive understanding of MPLS networks, their implementation, and their role in modern telecom infrastructure. Introduction Multi-Protocol Label Switching (MPLS) is a pivotal routing technique primarily utilized in telecommunication networks. In this case study, all telecom network nodes are located in specialized core rooms that maintain strict environmental conditions and uninterrupted power to ensure reliable performance. These core rooms are geographically distributed to m...
