Abstract: A data transmission method includes obtaining dequeue information that indicates a queue which requests to output data in a communications device and a target data volume that is output from each queue at a time, and the communications device manages the target data volume based on a burst value, reading, based on the queue, a sub-packet descriptor (PD) that is obtained by segmenting the first PD. the sub-PD includes target description information indicating a target data packet, the first PD includes first description information indicating a first data packet set including the target data packet, the first data packet set and the sub-PD are stored in a packet cache including a dynamic random access memory (DRAM), the first PD is stored in a control cache including a static random access memory (SRAM), and determining, the target data packet based on the sub-PD, and sending the target data packet.

Abstract: The present invention discloses a data caching method and apparatus, and relates to the field of network applications. The method includes: receiving a first data request; writing target data in the first data request into an on-chip Cache, and counting a storage time of the target data in the on-chip cache; enabling a delay expiry identifier of the target data when the storage time of the target data in the Cache reaches a preset delay time; and releasing the target data when the delay expiry identifier of the target data is in an enabled state and processing of the target data is complete.
