Method and system for estimating service system availability

Abstract

The invention provides a method and system for estimating service system availability. The method comprises the following steps: monitoring network element (NE) fault events in a service system, and acquiring the health scores of the NEs in accordance with preset rules, wherein each NE comprises nodes and links; acquiring the weights of the nodes in accordance with the times of the nodes which appear in service system links; acquiring the weights of the links in accordance with the nodes related to the links; and estimating the service system availability in accordance with the health scores of the NEs and the weights of the NEs based on a preset algorithm. The method and system for estimating the service system availability is used to realize the effective and accurate estimation of the service system availability.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for evaluating the usability of a service system. Background technique [0002] With the reverse development of information technology, business systems based on computer software technology are becoming more and more important in social and economic operations, especially in industries such as finance, communication, medical care and government affairs. For example, if the bank’s business system fails, the most basic financial services such as savings and loans will not be able to be carried out; if the securities business system fails, tens of billions of stock and fund transactions will not be carried out every day; if the medical business system fails, doctors will not be able to check the patient’s history Case and examination data, not even a prescription. The stable operation and continuous availability of business systems are indispensable for ...

But in practical applications, such as figure 1 The first core switch A1 and the second core switch A2 form a dual-core redundant structure. If the first core switch A1 fails, it will only cause the first business system server H, the second business system server N and the third business system There is a hidden danger in the availability of the system server M; if the second core switch A2 is also down, it will cause the first business system server H, the second business system server N and the third business system server M to be completely inaccessible; if the second server area If the link between the access switch C and the second business system server N is disconnected, only the second business system server N cannot be accessed, while the first business system server H and the third business system server M can operate normally

It can be seen that there is a close relationship between the relationship between nodes in the business system and the availability of the system, and the current real state of the business system cannot be accurately known according to the evaluation method in the above-mentioned prior art
