Traffic steering

Definition

Traffic steering is the process of directing network traffic based on certain criteria to optimize performance and resource utilization. This technique leverages Software-Defined Networking (SDN) principles to dynamically manage data flows, ensuring that traffic is routed efficiently across various paths and resources. In wireless and mobile networks, effective traffic steering can enhance user experience by improving bandwidth allocation and reducing latency, especially in environments with variable connectivity conditions.
