  The Internet s ability to support a wide range of services depends on the
network architecture and theoretical and practical innovations necessary for
future networks. Network architecture in this context refers to the structure
of a computer network system as well as interactions among its physical
components, their configuration, and communication protocols. Various
descriptions of architecture have been developed over the years with an
unusually large number of superficial icons and symbols. This situation has
created a need for more coherent systematic representations of network
architecture. This paper is intended to refine the design, analysis, and
documentation of network architecture by adopting a conceptual model called a
thinging (abstract) machine (TM), which views all components of a network in
terms of a single notion: the flow of things in a TM. Since cloud computing has
become increasingly popular in the last few years as a model for a shared pool
of networks, servers, storage, and applications, we apply the TM to model a
real case study of cloud networks. The resultant model introduces an integrated
representation of computer networks.
