Network architecture is the design of a communication network. It includes the physical and logical design of the network, the framework of accepted standards and specifications for elements, equipment, services, protocols and functions, growth and change hypotheses and high-level operating principles and procedures. Modern networks cover a variety of cloud network architecture and design principles, which a network organization must understand and articulate to maintain best practices. Standardized network protocols define how network elements interact, with the design of the network architecture that takes the lead in specifying the protocols used and how network elements use these protocols in the cloud. The robust network architecture will facilitate system-level functionality, as well as robustness, scalability and scalability in the face of changes in software and hardware components, application functions, implementation of security measures and environments. external.
