TS EN 62673

TS EN 62673 sets out a generic methodology for assessing and assuring the dependability of communication networks across the network life cycle. It focuses on analysing network topology, evaluating the dependability of service paths, and improving network configurations so that dependability performance and service dependability can be achieved and sustained. It also covers operating-phase practices such as network health checks, outage control, and test case management.

How dependability is understood in network engineering

In general technical usage, dependability is about how consistently a network can deliver the expected service, including its ability to continue operating through faults, interruptions, or degraded conditions. A methodology of this kind looks beyond individual components and considers end-to-end paths, topology, redundancy, and operational stability together. That is why it is relevant in carrier networks, enterprise communications infrastructure, and service-provider environments where service continuity depends on system-level behaviour.

Intended use in design and operations

This standard is intended for network service providers, network designers and developers, and network maintainers and operators. Its value lies in connecting design-time assessment with operational assurance: health monitoring, outage handling, and test case management are used to evaluate and sustain dependability performance during service operation. In practice, this supports a single dependability view from architecture choices through day-to-day network operation.
