Network Architectures • Many ways to build a network • Use network architectures to characterize different ways of building a network • The general blueprints that guide the design and implementation of networks are referred to as network architectures
Modularity in Network Architectures “architecture...defines how system is broken into parts & how those parts interact.” – from NewArch Final Report Layered models used to describe network protocols »useful for defining services offered by layers, and reasoning about correctness »but, layer boundaries often violated for performance reasons
connections between the buildings in a CAN is an increasingly common way to connect the individual LANs. These wireless connections or wireless bridges provide a quick, cost-effective way to connect buildings in a university campus, as shown in Figure 1.4. In a university campus environment, a CAN may link many buildings, including all of
On-chip networks (NoCs) enable global chip interconnections across the system. Regular or Irregular topology. Can increase node bristling factor. Can save area and power with simpler network (and router) design. Advanced designs can realize good cost/energy/performance trade-offs.
compose networking patterns to design or understand network architectures. Composition is challenging, and requires formality to be credible.
Figure 2-3 shows different connections and the flow of data as it goes from one application in a sending computer, through an interconnecting node, to another application in another computer.
