Problems solved by technology

[0003] The problem of DNS authoritative server availability failure is mainly found through internal monitoring and traffic analysis, but this method can only find problems from the perspective of operation and maintenance, and cannot accurately measure whether there is a failure, and the degree and scope of the impact of the failure from the perspective of users

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] The key technical problem solved by the invention is to find the usability failure of "the DNS authoritative server of the target domain name". DNS resolution mainly involves two paths: the user goes to the recursive server, and the recursive server goes to the authoritative server; therefore, two scenarios are considered, 1) Simulate the "DNS recursive server" and access the DNS authoritative server, such as figure 1 ; 2) simulate a "user", access the DNS authoritative server through the DNS recursive server of ISP (Internet Service Provider), such as figure 2 .

[0032] The present invention first sets monitoring points on each important network node or ISP server. For example, in China, the selected server needs to cover the main operators in each province as much as possible. This is because: 1) The DNS authoritative service of key domain names ...

Abstract

The invention discloses a DNS server availability detection method based on user perception. The method comprises the steps: (1) respectively setting a monitoring point on a set node server; (2) selecting M measurement data indexes; periodically transmitting an order to the monitoring point by a dispatching server to acquire the data; (3) calculating a benchmark service quality parameter Um of each index according to a benchmark DNS authoritative server sample set to obtain a set X minute; (4) calculating a service quality parameter Um minute of each index according to the acquired measurement data to obtain a set Y minute; (5) determining a contribution degree of each index relative to the benchmark service quality parameter according to the statistics correlation of the set Y minute and the set X minute; (6) calculating the service quality of each DNS recursive server according to the contribution degree of each index relative to the benchmark service quality parameter, and obtaining the availability of the target DNS authoritative server. According to the method, data support is provided from an external viewpoint so as to be used for the decision and judgment.

Description

technical field [0001] The invention relates to a DNS server availability detection method based on user perception, which belongs to the technical field of networks. Background technique [0002] The rapid development of the Internet has brought quick and convenient life and office. However, the frequent occurrence of network security incidents in recent years has also revealed the vulnerability of the Internet. Domain Name System (DNS), as one of the important infrastructures of the Internet, plays an indispensable role in ensuring the normal operation of the Internet. The security of DNS also affects the security and efficiency of the entire Internet. Therefore, the analysis and analysis of DNS security Research is even more important. When the DNS protocol was originally designed, security factors were not considered. The vulnerability of the protocol itself makes the DNS server often face various threats. [0003] The problem of DNS authoritative server availability ...
