    摘要： An abnormality detection device inputs a normal packet to a BERT model learned using the normal packet, and acquires a size of Attention for each byte portion when encoding of the normal packet is performed. Next, the abnormality detection device randomly samples an important byte portion of the normal packet based on the size of the acquired Attention of each byte portion. Then, the abnormality detection device generates a pseudo-abnormal packet by rewriting the random sampled important byte portion to a random byte. Thereafter, the abnormality detection device determines a threshold value of the abnormality degree for detecting the abnormal packet based on the abnormality degree of the normal packet group and the pseudo-abnormal packet group. Thereafter, the abnormality detection device detects an abnormal packet using the threshold value of the determined abnormality degree.

    摘要： Provided are methods and systems for reducing congestion in RoCEv2 networks. The method is configured to operate large-scale in data centers on traffic flowing from a sender node to a receiver node. The method described has three stages: a fast start stage, a transition stage, and a regulation stage. In the fast start stage, the sender sends data to the receiver at a fast initial rate. This may continue until the receiver observes a congestion event. When this happens, the sender reduces the data transfer rate as the method enters the transition stage. From a reduced rate, the method enters the regulation stage, where the rate is increased using a combination of a feedback control loop and an additive increase multiplicative decrease (AlMD) algorithm.

    摘要： Embodiments of the present disclosure provide a data packet transmission method, a communication device, a computer-readable storage medium, and a computer program product, and belong to the field of communication technologies. The method includes: obtaining a target data detection rule and a target processing rule for a target service flow; receiving a to-be-forwarded data packet; and determining, from the to-be-forwarded data packet, a target data packet belonging to a target group of the target service flow based on target data packet distinguishing information and a target group identifier that are included in the target data detection rule; determining data packet loss information in the target group; and determining that the target group is a target to-be-discarded group based on a target-group data packet loss threshold included in the target processing rule and the data packet loss information in the target group.
