Network Performance Monitoring and Diagnostic Analysis in Site Reliability Engineering Practices

Network performance and reliability are crucial in the digital age, where seamless service delivery is a competitive advantage. Site Reliability Engineering (SRE) is a field developed to improve system reliability through engineering approaches, with Network Performance Monitoring and Diagnostic Analysis (NPMD) serving as fundamental practices to achieve this goal. This paper explores the architecture and methodology of NPMD, integrating SRE principles with key metrics like SLIs, SLOs, and Non-Functional Requirements (NFRs). By examining real-time monitoring, diagnostics, and the role of automation in network reliability, this paper provides a technical foundation for implementing NPMD practices within SRE frameworks to enhance network resilience and performance.
