Abstract
Communication network reliability analysis is of great significance in the practice of network construction management and operation of telecom operators. It can provide an important scientific basis for the formulation of network construction strategy and the optimization and adjustment of network performance. Combining the theoretical results of reliability analysis with engineering application practice effectively in communication network operation has always been a research difficulty in communication network operation, which has high theoretical research value and market application prospect. This thesis work focuses on the improved network optimization method, discusses and extends the key technologies such as network topology, network model analysis index, network topology analysis method, calculation and analysis of evaluation results. Based on the classical network reliability analysis method, this thesis also does the following work, defines several main parameters that affect the network reliability analysis, puts forward the R-T (Ring-Tree) analysis method and the concept of branch line depth, and then finds out the approximate relationship between the branch line depth and network reliability through mathematical derivation. Finally, based on the theory proposed in this paper, a set of targeted network analysis tools is developed, and the proposed method is verified by using the local IP Bearer Network engineering data. The simulation results show that this method can quickly analyze the network reliability, significantly reduce the workload of data analysis, and give the targeted network optimization scheme. It can help the network operators to improve the network reliability quickly and effectively improve the network operation, management and maintenance ability of the operators.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
