Introduction

Communication networks aim to obtain user satisfaction with service performance, and their credibility is largely affected by the design and implementation of network service functions.

Impact.

The evolution of communication networks, the growth of services and the updating of functions are long-term challenges faced by network service providers. This is not only because of the the scope of storage services is broad and related to the activities that end users experience in connection with the services.

In order to maintain available business in network services, the communications industry needs to be careful to provide the following.

---Required network service functions;

---Sufficient network capacity and performance;

---Service security;

---service quality;

---Service credibility.

This document addresses one of the most important issues related to business trustworthiness assessment and delivery to ensure network service performance, while also it also solves the problem of application of network credibility assurance strategies and methods to enhance and maintain network operation.

This document describes a set of general methods for communication network credibility assessment and assurance, and provides relevant assessment and assurance means to support communication Trust network trust engineering applications. These methods are consistent with IEC 61907 and the International Telecommunications Union Telecommunication Standardization Bureau (ITU-T) concerning trustworthiness the recommended standards are consistent.

This document provides a network credibility analysis and evaluation method that can ensure the effective implementation of reliable network design.

The goal of this document is to formulate a set of cost-effective solutions that guarantee the trustworthy performance of the network and ensure the operation of the network from the service Gain from credibility.

Communication network credibility assessment and assurance methods

1 Scope

This document explains a set of general methods for communication network credibility analysis and evaluation from a life cycle perspective, and provides information for network topology analysis.

Network credibility assessment strategies and a complete set of methods for analysis, service path credibility evaluation and network configuration optimization to obtain network credibility and service Credibility. This document also focuses on network reliability assurance strategies and a complete set of methods, including network health check applications, network outage control Control and test case management to enhance and maintain the reliability of network service operations.

This document is applicable to network service providers, network designers and developers, and network operators engaged in network credibility assurance and service credibility assessment.

Network maintenance and operations personnel.
