Introduction

In order to meet various market demands and public communication needs, communication networks are becoming increasingly complex, such as mobile communication networks, e-commerce networks, internal

Department network and Internet services.

At the same time, the rapid development of communication technology provides effective network services and reliable performance required for the global communication field. like information exchange, data

Basic communication services such as data processing and network connectivity enable public and private communication work to be carried out effectively and under cost control. business and

The private sector relies heavily on these communication services that have become the fulcrum of their daily lives. An important step to ensure network performance and network service functions

The most important factor is credibility.

Network credibility is the ability of the network to operate normally and meet users' requirements for network performance and service operation when needed. from

From the user's perspective, credibility refers to the fact that the network service functions provided to meet the user's expected needs are credible and have this ability.

force. Network credibility is expressed through performance attributes, which include. network performance availability and service quality.

The network concept is an extension of the system concept, which provides the interconnection of network elements and the internal operating relationships of service functions that integrate specific communication goals.

A common framework is provided.

In order to provide both service functions and communication services, the network requires specific performance parameters. Network Trustworthiness Engineering is a specific

During this period, networks rarely reach the decommissioning stage. With the development of time, the network has accumulated new characteristic applications and continuously provided services for communication needs. net

The network life cycle is evolutionary and needs to solve technology convergence issues, update methods, and representation of specific trustworthiness attributes that meet network performance goals.
