Embodiment Construction

[0048] The specific implementation manners of the data sending method and system provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] An embodiment of the present invention provides a method for sending data, such as figure 1 As shown, the following steps may be included:

[0050] S101. The queue head of the main queue receives the valid data to be sent, and performs fragmentation processing on the valid data to be sent to form a data packet, and transfers the data packet to the first sub-data terminal in the main queue;

[0051] Among them, the main queue includes: a queue head and multiple sub-data terminals established with a serial link relationship; each sub-data terminal is used to establish a connection with a receiving device for data processing and transmission;

[0052] S102. After each sub-data end in the main queue processes and sends the received data packet, it passes it to t...

Abstract

The invention discloses a data transmission method and system. When the method is used for transmitting the same data (for example, one video frame, or one image) to a plurality of connections, the method just needs to carry out data segmentation and corresponding operation at a time, forms corresponding data packages, and sequentially transmits the data packages to subdata ends for data transmission. Therefore, compared with the prior art, the method provided by the invention does not need to enable each connection to independently carry out the TCP verification and calculation, and also does not need to enable each connection to independently carry out the segmentation which occupies the buffering memory, thereby reducing the repeated operation and redundant operation of effective data, reducing the additional expenditure of a system, improving the overall processing capability of the system, and also facilitating the reduction of the operation power consumption of embedded equipment.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data sending method and system. Background technique [0002] Currently, two programs on the network exchange data through a two-way communication connection, and one end of this connection is called a socket. Establishing a network communication connection requires at least a pair of port numbers (sockets). The essence of socket is the encapsulation of TCP / IP by the programming interface. TCP / IP also provides an interface for programmers to do network development. This is the socket programming interface. For example, HTTP is a car, which provides a specific form of encapsulation or display data. Socket is the engine, which provides the ability of network communication. Socket is usually also called "socket", which is used to describe IP address and port, and is a handle of a communication chain, which can be used to realize communication between different vir...
