Implementação de solução de transporte L2 utilizando MPLS na rede de um Provedor de Serviços de Internet (ISP)

Abstract

With the Internet playing a fundamental role in various services today, the infrastructure responsible for providing connectivity to end users has become as critical as the structure of an electricity provider. This fact leads Internet Service Providers (ISPs) to constantly strive to make their physical and logical infrastructures as available, scalable, and resilient as possible, aiming to ensure the best user experience. In this context, the implementation of Multiprotocol Label Switching (MPLS) in the provider has become a relevant proposal as it primarily aims to contribute to network resilience and scalability, with a direct impact on the quality of Internet services offered. By executing the MPLS implementation proposal, positive aspects were identified where this technology proved effective in ensuring service quality and traffic convergence, particularly in cases where primary routes failed. MPLS, through the creation of alternate paths and the use of labels for packet forwarding, provides greater flexibility and routing capacity, resulting in enhanced resilience and efficiency in delivering Internet services. Network resilience is enhanced by MPLS as it allows traffic redirection through alternative routes in situations where primary routes fail, avoiding significant interruptions in Internet access. Additionally, its scalability enables efficient management of the growing demand for connectivity, accommodating the increasing number of users and data traffic. Through the adoption of MPLS, ISPs can offer more reliable and stable connectivity with minimal service interruptions. This way, providers can meet user expectations, ensuring a more satisfying Internet experience without unwanted disruptions. Keywords: MPLS; Internet service Providers; convergence.
