Description

Network congestion measurement method, device, network card and storage medium Technical Field The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for measuring network congestion, a network card, and a storage medium. Background Network congestion refers to a phenomenon that a message in a network is lost or transmission delay is increased due to link congestion. Whether a packet is lost or delayed depends on the specific settings of the router, switch, etc. on the network link. Typically, when the network traffic is excessive, the messages are temporarily buffered in routers or switches, and if the device processing power is exceeded, the messages are discarded. For the network of the intelligent computation center, network congestion or packet loss is almost intolerable, the communication efficiency of the network can be seriously reduced, the training efficiency of an artificial intelligent large model in the intelligent computation center is further affected, the use efficiency of a large number of expensive computing acceleration cards of the intelligent computation center is seriously reduced, and the network becomes a bottleneck for improving the efficiency of the intelligent computation center. There are two methods for determining whether a network is congested currently in the industry, namely, a method for determining whether the network is congested based on a model estimation of delay, that is, a timestamp is attached when a message is sent, and a timestamp is returned after a receiving end receives the message, so that a transmitting end can calculate the delay from sending to receiving, and if the delay exceeds a certain threshold, the network can be determined to be in a congested state. Another method is based on a packet loss model, if the transmitted data packet is lost, the receiving end only receives a part of the data packet, and then informs the transmitting end, for example, if '10 data packets transmitted by you are received only 5, no. 1, 4, 7, 8 and 9 are received', the network is very likely to be congested. The delay-based model estimation only reflects congestion conditions of switching and routing devices in the network, and cannot feed back congestion conditions of communication endpoints, and visualization of network congestion is not the most intuitive. The packet loss based model is a metric comparison of congestion, and the discovery that packet loss occurs indicates that congestion is already very severe, which is unacceptable in intelligent computing networks. Therefore, it is important to feed back the congestion condition from the end to the end of the network as soon as possible, and avoid the congestion from deteriorating or even losing packets. Disclosure of Invention Accordingly, the present invention is directed to a method, apparatus, network card and storage medium for measuring network congestion. In order to achieve the above object, the technical scheme adopted by the embodiment of the invention is as follows: in a first aspect, the present invention provides a network congestion measurement method, applied to a first network card, where at least one communication channel exists between the first network card and a second network card, the method includes: After a preset periodic timer expires, sending a detection request message to the second network card with the highest priority, so that the second network card returns a detection response message with the highest priority after receiving the detection request message, wherein the detection response message carries the number of periodically received bytes of the second network card for receiving the service message from the first network card based on a communication channel to be detected in the last period time of the periodic timer; when the detection request message is sent, acquiring the number of bytes sent in the latest period time of the periodic timer based on the service message sent to the second network card by the communication channel to be detected, and acquiring the number of bytes received in the period after the detection response message is received; and determining the congestion degree of the communication channel to be detected according to the number of the periodic sending bytes and the number of the periodic receiving bytes. Optionally, the step of determining the congestion degree of the to-be-detected communication channel according to the number of bytes sent by the network card period and the number of bytes received by the opposite network card period includes: Calculating the difference value between the number of the periodically transmitted bytes and the number of the periodically received bytes of the network card and the number of the periodically received bytes of the opposite network card, and taking the difference value as the number of the on-line bytes of the communication channel to be detected i
