In times of distributed work and hybrid working environments, traditional network structures are increasingly reaching their limits. Traditional wide area networks (WANs) connect company locations and local networks via private or public transport technologies such as MPLS (Multiprotocol Label Switching) or VPN overlays. However, with increasing demands on agility, bandwidth and security, these static architectures are proving to be inefficient.
Traditional MPLS-based WANs have worked reliably for decades, but the growing volume of data due to cloud-based applications, streaming services and modern communication platforms is overloading existing structures. In addition, MPLS solutions are often associated with high costs, long contract terms and limited flexibility.
SD-WAN is a forward-looking alternative that enhances traditional WANs with software-driven intelligence. Instead of relying exclusively on fixed connections, SD-WAN enables dynamic route optimization based on real-time network conditions. Different connection types – MPLS, broadband Internet or LTE – are flexibly combined to reduce costs while maximizing performance.
Through intelligent bandwidth control, traffic prioritization and load balancing, SD-WAN ensures an even distribution of data traffic and minimizes latencies and bottlenecks. Central orchestration takes place via a cloud-based or on-premises controller, which enables agile management and greater security.
To take not only networking but also security and performance to a new level, many companies are extending SD-WAN solutions with Secure Access Service Edge (SASE) functionalities. This architecture combines network and security functions in a cloud-based solution. This means that data traffic is no longer necessarily routed via the central data center, but intelligently controlled via global PoPs (Points of Presence). This allows users to securely access company resources regardless of their location – with optimized speed and maximum protection.
