Hierarchy and Interconnectivity
Hierarchy Hierarchy is the degree of concentration of networks or traffic flows at interconnection points with in the network. Inter-connectivity It provides mechanism to achieve performance with in a hierarchical structure. The dynamic between hierarchy and inter-connectivity is perhaps one of the most fundamental trade-offs in the network architecture and design. Hierarchy provides separation of network into segments. These segments may be separate smaller networks or subnets or broadcast domains. When the amount of traffic in the network grows beyond the amount of network or when interaction between devices on the network result is congestion.
