Abstract

The invention discloses a message processing system and method. The system comprises a message cache region used for storing a received message and sending the message; a packet receiving queue used for storing the physical address of the received message; and a packet sending queue used for storing the physical address of a sent message and the length of the message. According to the technical scheme of the invention, the unified message cache region is adopted to store the received message and the sent message. Meanwhile, the address of the received message and the address of the sent message are respectively stored by the packet receiving queue and the packet sending queue, so that the zero-data copying of the full process, including the message receiving step, the message sending step and the message forwarding step, is realized. Meanwhile, the CPU processing time is effectively shortened, and the processing efficiency is increased.

Description

technical field [0001] The present invention relates to the field of message processing, in particular to a message processing system and method. Background technique [0002] The standard network card driver of the operating system is based on the data copy operation, that is, the message data is copied between the buffer in the operating system kernel address space and the buffer defined in the application program address space. However, the data copy operation causes a huge CPU overhead and limits the processing performance. Therefore, a zero-copy (zero-copy) technology is proposed to avoid unnecessary CPU data copy operations. However, although the traditional zero-copy mechanism can achieve zero-copy packet reception and transmission to a certain extent, it cannot realize zero-copy packet forwarding. Among them, the message receiving means that the network card hands over the received message to the CPU for processing; the message sending means that the CPU hands over ...
