Abstract: Example packet control methods and apparatus are described. One example method includes detecting a packet flow causing a congestion status change. A congestion isolation message is generated and is used to change a priority of a packet in the packet flow. The congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to at least one node.

Abstract: Example packet control methods and apparatus are described. One example method includes detecting, by a network node, a packet in a packet flow causing a congestion from an upstream node. The network node reduces a scheduling priority of the packet in the packet flow and generates a congestion isolation message, where the congestion isolation message includes description information of the packet flow. The congestion isolation message is sent to the upstream node to instruct the upstream node to reduce the scheduling priority of the packet in the packet flow.

Abstract: A database processing method and an apparatus are provided, and may be applied to a database system. A tree structure is used to represent a join order and used as an input of a neural network, and different first attribute matrices are allocated to different brother nodes in the input tree structure. This helps the neural network comprehensively learn information about the join order, obtain representation information capable of differentiating the join order from another join order, and predict costs of the join order accurately based on the obtained representation information of the join order. Then, an optimizer selects a join order with lowest costs for a query statement based on the costs predicted by a cost prediction module.

Abstract: This application provides a data transmission method and a network device. The method includes: sending, by a first network device, request information to a second network device; receiving, by the first network device, grant information sent by the second network device, where the grant information includes a first sequence number; determining, by the first network device, a first credit limit based on the first sequence number, where the first credit limit is an amount of data that is allowed to be sent by the first network device in a packet-distributed load sharing manner; and sending, by the first network device, data to the second network device based on the first credit limit.

Abstract: The present invention discloses a packet control method and a node device, to improve reliability of a data flow in a transmission process. The method includes: After receiving a pause frame, a first node automatically applies, based on adjustment information that is of a send queue of a data flow and that is recorded in a state record set, the pause frame to all queues associated in an adjustment process of the send queue of the data flow. In this way, a packet loss problem in a data transmission process can be avoided without adjusting an XOFF/XON threshold of a receive queue and without increasing a quantity of pause frames in a network system, thereby improving reliability of the data flow in the transmission process.
