NETWORK TOPOLOGY

Some Definitions

Graph of network. The diagram that gives the network configuration and uses lines with very small circles at the ends to represent a network element is called graph of network.

Tree. Any connected open set of branches which includes all nodes of a given graph is called tree.

Theorem of Topology. The basic theorem of thpolo is given as:

                                b=n+1-1

where b = number of branches,

           n = number of nodes, and

            I = number of independent loops.

Cut-set. Cut-set is that set of elements that dissociates two main portions of a network such that replacing any element will destroy this property. Each cut-set contains one tree-branch, the remaining elements being tree links. Tree-branches connect all the nodes in the network
