1 Introduction
This chapter mainly studies the theory and work practice of communication system architecture design. According to the new version of the exam syllabus, the knowledge points in this section will involve case analysis questions (25 points). In previous exams, case questions did not test this part of the content much. Although it is often tested in comprehensive knowledge selection questions, the score is Not high either. The content of this hour focuses on the memory and understanding of knowledge points. According to the rules of previous questions, the basic knowledge points of communication system architecture design are mostly derived from the basic network equipment and network architecture in the textbook and the latest hot topics technology outside the textbook. The knowledge architecture is shown in the figure below:
Communication system architecture is the infrastructure and system environment of software architecture. In architecture practice, the performance, availability, reliability and other quality attributes of software are largely affected by the infrastructure and environment. Good The infrastructure can effectively help improve the performance and availability of the system architecture and enhance reliability.
