Abstract

The invention discloses a control method and device. The method comprises the stepsthat: a link layer returns an NACK (negative acknowledgement) message to a sending end when receiving an error message in a receiving direction and initiates a retransmission order, and an intermediate layer triggers a retransmission counter to add an value by 1; when the retransmission times of the same message are less than or equal to the preset retransmission times, the retransmission counter is triggered for reset; and when the retransmission times of the same message are greater than the preset retransmission times, a bottom physical layer is triggered for reset. With the adoption of the technical scheme, the data transmission stability and reliability can be effectively ensured, system resources can be reliably and effectively used, and the control method and device have a very high application value in a high-end server system.

Description

technical field [0001] The data transmission control technology of the present invention specifically relates to a control method and device. Background technique [0002] With the rapid development of computer technology and integrated circuit technology, information fields such as huge data calculation and data analysis, complex graphic analysis and scientific budgeting have extremely high requirements on the performance and reliability of server systems. In order to meet the needs of the development of high-performance and high-reliability server systems, the requirements for high-bandwidth data transmission and high-reliability data transmission capabilities are the basic characteristics of server systems. [0003] In related technologies, the transmission of data packets is as follows: figure 1 shown by figure 1 It can be seen that there is no control mechanism for data packet transmission, and the control of data packet transmission can greatly improve the reliabilit...
