Overview
IEC 62673:2013 establishes a comprehensive methodology for the assessment and assurance of communication network dependability throughout the network life cycle. Published by the International Electrotechnical Commission (IEC), this international standard provides a structured approach to analyzing network topology, evaluating the dependability of service paths, and optimizing network configurations to achieve reliable and high-performing network services. Furthermore, IEC 62673:2013 details network dependability assurance strategies, including health checks, outage control, and test case management, all aimed at enhancing and maintaining dependable network operations.
Network dependability is a critical concern for service providers, designers, developers, maintainers, and network operators. Ensuring consistent and resilient operation of communication networks not only supports user satisfaction but also underpins the business sustainability of network providers.
Key Topics
- Network Dependability Assessment: Strategies for assessing dependability by analyzing network topology, service path reliability, and configuration optimization.
- Service Path Evaluation: Techniques to evaluate and improve the dependability and resilience of data transmission between communication nodes.
- Dependability Assurance: Methodologies for maintaining network performance, such as regular health checks, managing network outages, and systematic test management.
- Life Cycle Perspective: Integration of dependability practices across all network life cycle stages, from concept definition to operation, enhancement, and retirement.
- Performance and Quality of Service (QoS): Emphasis on achieving and maintaining high network availability, reliability, maintainability, and service integrity.
- Service Scenarios: Consideration of both end-to-end (E2E) and full-end network service scenarios to meet the needs of both end users and service providers.
Applications
IEC 62673:2013 is particularly relevant for a broad range of practical applications within the communications industry, including:
- Network Design and Development: Utilized by network architects and engineers to ensure robust design and optimized topology, supporting long-term dependability requirements.
- Service Providers: Enables telecom and data service providers to assess and assure their service reliability, directly benefitting customer satisfaction and operational excellence.
- Operations and Maintenance: Assists network operators and maintainers in implementing systematic health checks, outage management, and corrective actions to minimize service interruptions.
- Performance Evaluation: Provides methodologies to collect, analyze, and act on network performance metrics and feedback, leading to continuous improvement in network dependability.
- Risk and Scenario Analysis: Supports risk assessment and scenario-based evaluations, allowing for informed decision-making prior to network modifications or expansions.
By applying this standard, organizations can ensure their networks operate with high levels of availability and resilience, directly contributing to service quality and customer trust.
