Data stream and data packet transmission method and device

摘要

A data stream and data packet transmission method and device are described, relating to the field of interface data transmission technologies. The method includes: a home end detects whether data to be transmitted is a data stream or a data packet; when it is detected that the data stream and the data packet exist simultaneously, the data stream is preferentially transmitted; and upon completion of transmission of the data stream, then the data packet is transmitted. According to the embodiments of the disclosure, when the data stream and the data packet exist simultaneously, high efficiency transmission of the data stream may be achieved with no need of extra external time for scheduling operations, effectiveness of transmission of the data stream is enhanced, and data transmission efficiency through the interface is improved.

主权项

1. A data stream and data packet transmission method, comprising:
detecting whether data to be transmitted is a data stream whose transmission is not interrupted or stopped or a data packet according to a control character which identifies a data transmission type; when it is detected that the data stream and the data packet need to be simultaneously transmitted through one interface, preferentially transmitting the data stream; and upon completion of transmission of the data stream, then transmitting the data packet; wherein, the step of preferentially transmitting the data stream comprises:
when transmitting the data stream, after finishing transmission of the data stream, transmitting the data packet;when transmitting the data packet, stopping transmitting the data packet once the data stream needs to be transmitted, and inserting the control character which indicates interruption of transmission of the data packet into the data packet whose transmission is interrupted; and then transmitting the data stream needs to be transmitted, until finishing transmission of the data stream needs to be transmitted, transmitting the data packet whose transmission is interrupted; wherein the control character comprises:
a delimiter, configured to distinguish whether data is the control character or data;a command type, configured to indicate a current link state; andstate data, configured to indicate information as a packet type of the data to be transmitted and whether the data packet is interrupted.
