WebJan 10, 2024 · The primary function of the spanning-tree algorithm (STA) is to cut loops that redundant links create in bridge networks. The STP operates at Layer 2 of the Open System Interconnection (OSI) model. By means of bridge protocol data units (BPDUs) that exchange between bridges, the STP elects the ports that eventually forward or block traffic.

If G is itself a tree, then t(G) = 1.; When G is the cycle graph C n with n vertices, then t(G) = n.; For a complete graph with n vertices, Cayley's formula gives the number of spanning trees as n n − 2.

WebFeb 17, 2024 · A spanning tree is the result of a DFS traversal of a graph. A graph with no loops is known as a spanning tree. We use a Stack data structure with a maximum size equal to the number of vertices in the Graph to implement DFS traversal. To implement DFS traversal, we take the following stages.
