Embodiment Construction

[0029]Such asfigure 1 As shown, a link packet loss rate reasoning method in an uncertain network environment, including the following steps:

[0030](101) Get the topology of the target network: the upper fault management system re-establinates the target network topology that needs to be positioned by the inter-device interconnected link information through the interface acquisition equipment network management;

[0031](102), the transmitting end is detected and received a probe result, which is the path packet loss rate obtained by the detection;

[0032](103), such asfigure 2As shown, the path status is determined according to the path packet loss rate, thereby determining the link state, the specific process is as follows:

[0033](301), each selected the longest path in the network, that is, starting from the path passing through the link, the maximum number of times can reduce the number of cycles, reduce the number of end-to-end measurements, reduce additional Expenditure makes the algo...

Abstract

The invention discloses a link packet loss rate reasoning method in an uncertain network environment, comprising the following steps: (101), acquiring the topology of the target network; (102), sending end-to-end detection and receiving the detection result, the detection The result is the path packet loss rate obtained by detection; (103), determine the path state according to the path packet loss rate, thereby determining the link state; (104), use lognormal distribution fitting to obtain 1-state and 2-state links The packet loss rate range; (105), output the packet loss rate range of all links. The invention improves the relevant algorithm and process of the prior art, proposes a packet loss reasoning method for uncertain factors in a real network environment, and greatly improves the accuracy of measuring link packet loss rate.

Description

Technical field[0001]The present invention relates to a network data processing method, in particular a link packet loss rate in a network environment.Background technique[0002]In recent years, the rapid development of emerging network technologies represented by the Internet and the next generation of Internet has produced huge pressure. However, with the rapid development of new technologies, the IP network network environment becomes more and more uncertain, and its network size is constantly expanding, and new network features have made severe challenges for traditional IP network performance management technology. Existing detection network internal properties such as link packet loss rates and data report delay are primarily used by network chromatography. Network chromatography technology proposes to determine the link status in the network in the network, which is a conventional packet loss rate inferior technology for inferring the internal experimental data of the network ...
