一种数据传输方法、装置及客户终端设备制造方法及图纸

一种数据传输方法、装置及客户终端设备。客户终端设备CPE接收网络设备发送的第一下行数据包，存储第一下行数据包，创建并维护第一下行数据包的上下文条目。CPE向终端发送第一下行数据包。CPE接收终端发送的第一下行数据包的确认数据包，更新第一下行数据包的上下文条目。CPE若根据第一下行数据包的上下文条目确定需要进行第一下行数据包的重传，则向终端重传存储的第一下行数据包。CPE若根据第一下行数据包的上下文条目确定需要清除存储的待清除下行数据包及其上下文条目，则清除所述待清除下行数据包及其上下文条目，以提高终端与CPE之间TCP数据传输的吞吐量。

A Data Transfer Method, Device and Client Terminal Equipment

A data transmission method, device and customer terminal device are provided. The client terminal device CPE receives the first downlink packet sent by the network device, stores the first downlink packet, and creates and maintains the context entry of the first downlink packet. The CPE sends the first downlink packet to the terminal. The CPE receives the confirmation packet of the first downlink packet sent by the terminal and updates the context entry of the first downlink packet. If the CPE determines that it needs to retransmit the first downlink packet according to the context entry of the first downlink packet, it retransmits the stored first downlink packet to the terminal. If the CPE determines that the stored downlink packet and its context entry need to be cleared according to the context entry of the first downlink packet, the downlink packet and its context entry to be cleared will be cleared to improve the throughput of TCP data transmission between the terminal and CPE.
