The topology of a network is the geometric representation of all links and nodes of a network—the structure, consisting of transmission links and processing nodes, that provides communications connectivity between nodes in a network. A link is the physical transmission path that transfers data from one device to another. A node is a network addressable device.

Graph theory describes certain characteristics of a network topology such as the average node degree for robustness (average number of links terminating at a node in a network), network diameter for size (the longest/shortest path between any two nodes in a network), number of paths for complexity (total number of paths between all node pairs), and cutsets for flow (minimum number of removed links to partition a network). However, the most dominant characteristic of a network topology is its shape.
