Heterogeneous network communication system-based data processing method

Abstract

The invention discloses a heterogeneous network communication system-based data processing method, thereby realizing data transmission between the ethernet network and a low-speed network. The ethernet network adds a customized packet header and a data packet length field to a read ethernet link layer data packet and then stores the packet, and an address and a data packet length of the storage space are buffered into a data buffering queue; the low-speed network obtains the address and the data packet length from the data buffering queue and then takes the ethernet link layer data packet out of the storage space and sends the packet out; when the low-speed network sends data to the ethernet network, received data packets are spliced into an ethernet link layer data packet for sending. According to the invention the data received by the high-speed ethernet network are processed into one in a data format that can be identified by other networks and the data transmitting speed is reduced by a buffering way, so that the low-speed network can receive the data completely. Therefore, data transmission between the heterogeneous network communication systems can be processed with high efficiency.

Description

technical field [0001] The invention relates to a communication system data processing method, in particular to a data processing method based on a heterogeneous network communication system. Background technique [0002] The so-called heterogeneous network (Heterogeneous Network) is a type of network composed of computers, network devices and systems produced by different manufacturers, and most of them run on different protocols to support different functions or applications. Since a network with only one architecture (such as an X.25 network) cannot meet the needs of all users, heterogeneous networks are widely used. [0003] Regardless of the hardware structure of the specific network used, as long as the network uses the IP protocol and assigns legal IP addresses to the hosts connected to the network, any pair of computers connected to this virtual IP Internet can It is very convenient to communicate. [0004] The Internet is formed by the interconnection of a large n...

AI Technical Summary

Problems solved by technology

In the communication between high-speed Ethernet and serial port network, the communication speed of serial port is much lower than the communication speed of Ethernet, so when communicating between Ethernet and serial port network, a large data buffer queue is required, but because the communication speed of serial port drops sharply , so real-time data communication cannot be carried out, only low-speed data transmission and exchange can be carried out
