Abstract

The invention discloses a data transmission method and data transmission equipment. The method comprises that: when a data packet to be transmitted is determined to be fragmented according to the dimension information of the data packet to be transmitted, an internet protocol (IP) protocol stack fragments the data packet to be transmitted; and the IP protocol stack calls a rapid input / output (RapidIO) driver to transmit the processed fragmented data. In the method, by fragmenting the data packet to be transmitted through the IP protocol stack and transmitting the processed fragmented data through the RapidIO driver, the transmission rate can be improved; the RapidIO message transmission process is responsive transmission and belongs to reliable transmission; and if link congestion occurs, the data can finally reach an opposite terminal.

Description

technical field

[0001] The present invention relates to the field of communication technology, in particular to a data transmission method and equipment. Background technique

[0002] The IP (Internet Protocol, Internet Protocol) datagram fragmentation principle in the Ethernet network is specifically: in the IP protocol, due to the limitation of the maximum amount of data that can be carried by the link layer (called the maximum transmission unit MTU), When the size of the sent data payload exceeds the size of the MTU, the data cannot be delivered to the output link as a whole, so the data can be "fragmented" into two or more smaller datagrams, and then sent to the output link These smaller datagrams, called "slices", are sent on the computer. Among them, the slice needs to be reassembled before reaching the transport layer of the destination through the link layer, so that the receiver is located in the TCP (Transmission Control Protocol, Transmission Control Protocol) an...
