ENUM query fault detection and avoidance method

Abstract

The invention discloses an ENUM query fault detection and avoidance method, and aims at the fault performance that the response time delay of an ENUM server is continuously increased or the response rate of the ENUM server is continuously reduced. The method comprises: fitting a function through data, and predicting occurrence of a phenomenon; and observing whether the abnormity is relieved or not by adjusting and reducing the load ratio sent to the corresponding server so as to dynamically plan the following load adjustment and processing. According to the invention, the method is realized by introducing a multi-order curvilinear equation fitting process based on a matrix equation and a computer algorithm, is used for predicting and calculating the response rate, and realizes preliminary automation by utilizing an intelligent algorithm; and a set of strategy process for dynamically adjusting and recovering the load ratio is constructed, and compared with one-step load transfer, the method has relatively high flexibility and non-manual intervention capability.

Description

technical field [0001] The invention relates to the technical field of 5G communication, in particular to a method for detecting and avoiding ENUM query faults. Background technique [0002] In the context of VoLTE and 5G, with the popularization of number portability services, business systems represented by SMS and messaging platforms have a sharp increase in the performance and reliability of querying the ENUM system in large regions to obtain user information. [0003] The ENUM query process is established on the UDP-based DNS protocol. Unlike connection-based TCP, connectionless UDP does not guarantee the reliability of data transmission, and cannot accurately and timely know the result of data transmission when the network itself is reachable. However, in some key processes such as message delivery and callee attribution query, the inability to quickly and correctly obtain the ENUM query result is tantamount to directly declaring that the delivery of the message has f...

AI Technical Summary

Problems solved by technology

Since the ENUM / DNS protocol has been encapsulated, it is less feasible to improve the reliability through the above-mentioned modification of the transmission protocol or the network system

[0005] In the case of large-scale and massive concurrent queries, if the method of judging whether the response is returned by synchronously waiting for the response will cause serial congestion, which seriously restricts the concurrency capability in terms of speed

[0006] If the method of regularly sending status detection packets for response detection is used, a large number of queries will be lost in the process of waiting for the detection results in the event of a failure

And in view of the partial loss of the response packet and the excessive delay, the detection of a single detection packet cannot accurately detect the fault
