Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0047] The detection logic schematic diagram of the existing network quality detection scheme is as follows: figure 1 As shown, wherein, Cm|n represents a detection message, Sm|n represents a response message, and m ...

The invention discloses a link quality event detection method, an intelligent terminal and a storage medium. The method includes: determining a candidate event corresponding to a link quality event according to a first sequence number and a first confirmation number corresponding to a first response message ; When the candidate event is not unique, determine the target event corresponding to the link quality event from the candidate events according to the second sequence number and the second confirmation number corresponding to the second response message; when the target event contains the second response message When lost, acquire the length of the first response packet, and determine whether the second response packet is aggregated with the first response packet according to the length of the first response packet. The present invention detects the link quality event according to the serial number, the confirmation number and the message length of the response message, not only can quickly detect the link quality event, but also can distinguish that the response message is a real packet loss event. Events or packets are aggregated by the network card to improve detection accuracy.
Description
technical field [0001] The invention relates to the technical field of network measurement, in particular to a link quality event detection method, an intelligent terminal and a storage medium. Background technique [0002] The existing network link detection scheme is based on the TCP protocol, which first generates legal message content that conforms to the upper layer protocol, establishes a three-way handshake connection on the TCP link, and controls the size of the sending and receiving message by adjusting the MSS field. Based on the packet pair technology, each detection sends two packets back to back (that is, a pair of packet pairs), and by modifying the size of the local receiving window, the server can be limited to only respond to each forward packet a datagram. [0003] However, although existing network link detection schemes can detect the connection quality of network links, they cannot quickly judge network link quality events such as packet loss and out-of...
