Abstract

The invention discloses a data transmission method and equipment, which are used for solving the problem that an acceleration scheme of a network card in the prior art cannot be suitable for a 5G wireless network. An FPGA module in the network card provided by the embodiment of the invention firstly classifies the data packets according to protocol types supported by the data packets, and then processes the data packets according to the corresponding protocol types, classifies and merges IP layer data streams, and segments and recombines UDP layer data packets. According to the embodiment of the invention, the FPGA module is adopted to process data packets of different protocol types in network transmission or accelerate fragmentation and recombination; a general server CPU is not needed to realize a network protocol function, so that the processing resource requirement on the server CPU can be reduced, the processing delay of a server network transmission protocol is reduced, the processing performance of the server is greatly improved, and the equipment requirement of 5G wireless service can be met.

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] Research on 5G wireless network technology is currently a hot spot in the communication field, and the 5G network performance indicators defined by 3GPP (3rd Generation Partnership Project, the third generation mobile communication standardization organization) (mobile user experience rate of 1Gbps order, 1 million connections / square kilometers, and the service plane delay is less than 1ms) poses a huge challenge to the existing wireless communication technology. [0003] The 5G wireless network will be a cloud network based on the C-RAN (Radio Access Network, wireless access network) architecture. OTN (Optical Transport Network, Optical Transport Network) optical network, midhaul bearer and backhaul bearer adopt OTN+IPRAN (IP Radio Access Network, IP-based wireless access network) transmissio...
