Message transmission method and network equipment

Abstract

The invention provides a message transmission method and network equipment. The message transmission method comprises that: a central processing unit (CPU) generates the message control information of a message to be transmitted; the CPU fragments an extended message comprising the message control information according to predetermined rules, and sequentially stores the related information of message fragments into a buffer; an application specific integrated circuit (ASIC) reads the related information of the message fragments, reads the message fragments according to the related information of the message fragments, and restructures the message fragments to obtain the extended message; and the ASIC resolves the restructured message to obtain the message control information and the message to be transmitted, and transmits the message to be transmitted according to the message control information. By the message transmission method and the network equipment provided by the invention, highly-efficient message transmission can be realized, thereby improving network performance.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a message sending method and network equipment. Background technique [0002] With the popularization of science and technology, network communication technology has penetrated into various fields with an irreplaceable position, and network communication needs to be realized by sending and receiving messages. [0003] In the existing method of sending a message, the central processing unit (CPU) provides the content of the message and the control file for sending the message to the ASIC through the memory at the same time, and the ASIC sends the message according to the control file for sending the message. In the prior art, the message sending method usually adopts the following process: the CPU transmits the control information of the message and the message to the ASIC through the memory, and the ASIC obtains the message and the control information of the message and th...

Problems solved by technology

[0004] In the above-mentioned message sending method in the prior art, since the extended message needs to be stored in the newly applied memory block, on the one hand, each time a message is sent, the memory for storing the original message needs to be maintained at the same time. Therefore, it takes a certain amount of time to apply for and release memory, and at the same time increases the consumption of memory resources; on the other hand, the message needs to be copied from the original memory block to the new one. In the requested memory block, memory copying takes a certain amount of time, especially when the message is a long message, this consumption will increase significantly

Since CPU sending packets is a very frequent operation, the large overhead of sending packets greatly reduces the performance of the entire switch.
