The hierarchical network model is part of the scale-free model family sharing their main property of having proportionally more hubs among the nodes than by random generation; however, it significantly differs from the other similar models (Barabási–Albert, Watts–Strogatz) in the distribution of the nodes' clustering coefficients: as other models would predict a constant clustering ...
Hierarchical network models are, by design, scale free and have high clustering of nodes. [33] The iterative construction leads to a hierarchical network. Starting from a fully connected cluster of five nodes, we create four identical replicas connecting the peripheral nodes of each cluster to the central node of the original cluster.
While the hierarchical database model structures data as a tree of records, with each record having one parent record and many children, the network model allows each record to have multiple parent and child records, forming a generalized graph structure. This property applies at two levels: the schema is a generalized graph of record types ...

The Hierarchical internetworking model is a three-layer model for network design first proposed by Cisco in 1998. [1] The hierarchical design model divides enterprise networks into three layers: core, distribution, and access.
NOMAD remains an extremely stable product that is enhanced to keep up with contemporary needs, such as access to Oracle and SQL Server data on mid-tier platforms, full e-mail support and additional types of output formatted in HTML, XML, and PDF. A new line of products began later in the 1990s, starting with RP/Web.
Systems Network Architecture [1] (SNA) is IBM's proprietary networking architecture, created in 1974. [2] It is a complete protocol stack for interconnecting computers and their resources. SNA describes formats and protocols but, in itself, is not a piece of software.
