Network data transmission method and front-end machine

Abstract

An embodiment of the present invention provides a network data transmission method and a front-end processor, wherein the method is applied to a data transmission network including multiple terminals and multiple front-end processors, and each terminal corresponds to a front-end processor, and the method includes : the first front-end processor acquires the first network data whose destination address is the address of the second terminal sent by the corresponding first terminal, and encapsulates the first network data to obtain the first text data, the first text data The destination address is the address of the second front-end processor corresponding to the second terminal, and finally the first text data is sent to the second front-end processor, so that the second front-end processor performs corresponding processing and sends it to the second terminal. The technical solution of the present invention does not require the first front-end processor to analyze the application layer protocol involved in the first network data, simplifies the processing logic complexity of the first front-end processor, and reduces the probability of failure of the first front-end processor , improving the stability of the data transmission network.

Description

technical field [0001] The invention relates to the technical field of power system information communication, in particular to a network data transmission method and a front-end processor. Background technique [0002] The relevant regulations on the security protection of the power monitoring system require that the security protection of the power monitoring system should adhere to the principles of security partition, network dedicated, horizontal isolation, and vertical authentication to ensure the security of the power monitoring system and power dispatching data network. Therefore, if individual businesses or their functional modules (or subsystems) in the production control area (high-density network) of the power monitoring system need to use public communication networks, wireless communication networks, and networks in uncontrolled states When the equipment communicates with terminals in the low-density network, a secure access area should be set up, and the commu...
