Abstract

Metro networks play a crucial role in providing high-speed communication services to large urban areas, serving as the backbone of connectivity between local area networks (LANs) and the broader internet. Traditional metro networks often face challenges in terms of scalability, flexibility, and security as they grow in complexity and traffic volume. This paper introduces the concept of dynamic tunnels in metro networks to address these challenges. Dynamic tunnels enable on-demand creation, modification, and tear-down of secure communication paths between network nodes, improving scalability, flexibility, and resource optimization. We propose an implementation model for dynamic tunnels using existing tunneling protocols such as GRE (Generic Routing Encapsulation), IPsec, and MPLS (Multiprotocol Label Switching). Furthermore, we explore the potential benefits, challenges, and performance implications of dynamic tunnels in metro networks, with a focus on security, traffic management, and quality of service (QoS).
