Epoch network state monitoring method

Abstract

The invention provides an epoch network state monitoring method, and the method comprises the steps of obtaining a data package transmitted by a receiver in a period of time, and the data package comprises epoch time; marking the serial number of the received data packet according to the epoch time; counting the number of intervals between the serial numbers of the adjacent data packets and the occurrence frequency of each interval number, and calculating the total packet loss number according to each interval number and the occurrence frequency thereof; calculating the concentration ratio of the interval number according to the interval number and the total packet loss number; and judging the epoch network state according to the concentration degree.

Description

technical field [0001] This specification generally relates to the technical field of navigation and positioning, and in particular relates to a method for monitoring the state of an epoch network. Background technique [0002] The ground-based augmented network is characterized by wide distribution and evenly distributed points in all provinces across the country. The total number of stations built nationwide reaches thousands, and each station transmits epoch data through various wide area network technologies. The requirements for availability are high, and the relevant indicators require accuracy. to the sky. In network monitoring, especially in large-scale WAN network monitoring, it is very important to monitor the network link transmission quality of each site. When the number of sites is large and the sites cover a wide range (such as covering all provinces in the country), how to efficiently and accurately reflect the network link quality of each site in the entire ...

[0007]2) Horizontal comparison is difficult: each site must check the corresponding plotted graphics one by one. When you want to make a horizontal comparison of hundreds or thousands of sites, this The job becomes almost impossible

[0010]2) Insufficient accuracy: the initial value of the serial number of the RTP data packet is random, the initial value of each data stream is different, and the audio / video data is different Parameters such as the flow sampling ratio are different, that is, the scales for measuring network quality are different; the actual application data packets will not be sent evenly, and often vary according to the actual situation.

In addition, application data is often built on the TCP protocol, and data packet loss often triggers protection mechanisms such as TCP retransmission. Under this mechanism, application data loss cannot be reflected through ICMP.

Specific to the scenario of this article, the epoch packet loss of each base station cannot be accurately monitored through PING monitoring
