Network design

Definition

Network design refers to the process of planning and creating a network that effectively connects various points while optimizing resource usage, minimizing costs, and ensuring reliability. This concept plays a crucial role in determining how information flows within a system, whether it's through the arrangement of nodes and edges or managing capacities in flow networks. Effective network design is essential for applications such as communication systems, transportation, and data processing.
