These two tools use the ICMP protocol to send a certain ICMP packet to the destination network, and then judge the current network situation according to the ICMP return packet delay, packet loss rate, number of hops passed, route passed, etc., but Its disadvantage is that the above indicators returned are fragmented and isolated
Moreover, because a single tool cannot obtain all the above indicators at the same time, it takes a long time to apply multiple tools for serial testing at the same time, and the operation is relatively duplicative, and it is difficult to learn from the data association between each node on the network, each indicator Extracting effective reference information from data association requires testers to have very professional network knowledge and rich testing experience and skills. Excessive reliance on the experience of testers will introduce too many subjective factors, which will easily lead to network quality degradation. Misjudgments or large deviations in judgment results

Embodiment Construction
[0044] In order to make those of ordinary skill in the art more clearly understand the technical problems, technical solutions and beneficial technical effects to be solved by the present invention, the present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.
[0045] Please refer to figure 1 , a method for quickly and accurately measuring the quality of a network link, the method comprising:
[0046] S100: Send multiple ICMP request response packets from the source host to the destination host through the network link.
[0047] The routine of this network link quality measurement method runs on the source host, and the entities of the whole scene include: source host (1), network nodes (2, 3, 4, 5, 6, 12) between the source host and the target host , 13, 14, 15, 16, 17, 18, 19, 20), target host (7).
[0048]It should be noted that this method first uses the ICMP protocol to find out the nodes passed from the source h...

A method for quickly and accurately measuring the quality of a network link of the present invention, the method comprising: sending a plurality of ICMP request response packets from a source host to a destination host through a network link; obtaining the ICMP request response packets through the network The link information of the link, the link information includes the number of nodes and the IP address of each node; according to a preset strategy, calculate the packet loss rate, average delay and delay standard deviation of each node; set the Calculate factors and weights corresponding to the packet loss rate, average delay, and delay standard deviation of each node, and calculate the link quality score of the network link according to a preset algorithm. The network link quality measurement method makes the test more rapid and objective through parallel testing, and users can set various network indicators according to different application scenarios and specific needs.
Description
technical field [0001] The invention relates to the field of network communication, in particular to a method and device for quickly and accurately measuring network link quality. Background technique [0002] Currently, WAN network quality diagnosis mainly relies on tools such as ping and traceroute. These two tools use the ICMP protocol to send a certain ICMP packet to the destination network, and then judge the current network situation according to the ICMP return packet delay, packet loss rate, number of hops passed, route passed, etc., but Its disadvantage is that the above indicators returned are fragmented and isolated. Moreover, because a single tool cannot obtain all the above indicators at the same time, it takes a long time to apply multiple tools for serial testing at the same time, and the operation is relatively duplicative, and it is difficult to learn from the data association between each node on the network, each indicator Extracting effective reference ...
