Problems solved by technology

In the prior art, the TCP (Transmission Control Protocol, Transmission Control Protocol) point-to-point communication method, the communication between any two systems adopts the TCP method, and when one system sends messages to other systems, it needs to send multiple times and the performance is low. To solve the above problems, transmit data through UDP (User Datagram Protocol, User Datagram Protocol) multicast communication mode, and support one system to broadcast data to multiple systems at the same time, but transmitting data through UDP multicast communication mode cannot guarantee the receiver's data reception Orderly, orderly processing of data cannot be guaranteed

Embodiment Construction

[0041] In the prior art, data is transmitted through UDP multicast communication, which supports one system to broadcast data to multiple systems at the same time, but data transmission through UDP multicast communication cannot guarantee the order of data reception by the receiver, and cannot guarantee the order of data deal with. In order to overcome the above-mentioned technical problems, the present application proposes a data multicast transmission method, which can ensure that the order of the data received by the receiving end is consistent in multiple systems.

[0042] The embodiment of this application discloses a data multicast transmission method, see figure 1 As shown, the method may include the following steps:

[0043] Step S11: Receive network data packets sent by multiple senders through the FPGA, and determine whether the network data packets are target multicast data.

[0044] In this embodiment, the network data packets sent by multiple senders are first r...

Abstract

The invention discloses a data multicast transmission method and device, equipment and a storage medium. The method comprises the following steps: receiving network data packets sent by a plurality of sending ends through an FPGA, and judging whether the network data packets are target multicast data or not; if yes, numbering the network data packets according to a receiving sequence by utilizing an FPGA to obtain the network data packets containing receiving numbers; and sending the network data packet containing the receiving number to a corresponding target receiving end through data exchange equipment. Multicast data is numbered in a unified manner according to a receiving sequence through FPGA equipment, and then network data packets containing receiving numbers are sent to corresponding receiving ends, so that each receiving end can process the data according to a numbering sequence, the sequence of the data, received by the receiving ends, of multiple systems is ensured to be consistent, and the problem that the sequence of received multi-party data is inconsistent is solved.

Description

technical field [0001] The invention relates to the field of data transmission, in particular to a data multicast transmission method, device, equipment and storage medium. Background technique [0002] At present, in the financial field, it is often necessary to realize data interaction between multiple systems through a data bus. The performance, consistency, reliability and stability of the bus have become the key factors of a trading system. In the prior art, the TCP (Transmission Control Protocol, Transmission Control Protocol) point-to-point communication mode, the communication between any two systems adopts the TCP mode, and when one system sends messages to other systems, it needs to send multiple times and the performance is low. To solve the above problems, transmit data through UDP (User Datagram Protocol, User Datagram Protocol) multicast communication mode, and support one system to broadcast data to multiple systems at the same time, but transmitting data thro...
