Phytium processor-based network communication device

Abstract

The present invention provides a network communication device based on a Feiteng processor, comprising: a Feiteng processor, the first end of the Feiteng processor is electrically connected to the first end of a first network chip, and the second end of the Feiteng processor end is electrically connected with the first end of the second network chip, and the third end of the Feiteng processor is electrically connected with the first end of the programmable logic device; the first communication connector, the first communication connector is connected with the first The first end of the relay is electrically connected, the second end of the first relay is electrically connected to the second end of the first network chip, and the first communication connector is used to receive external network data, and through the first A relay and the first network chip are transferred to the Feiteng processor for processing. The Feiteng processor-based network communication device provided by the invention extends the detection of software and hardware faults and improves the efficiency of bypass transmission.

Description

technical field [0001] The invention relates to the communication field, in particular to a network communication device based on a Phytium processor. Background technique [0002] In the field of communication systems of industrial networks such as electric power, petroleum, rail transit, and municipal administration, for security reasons, security network devices are usually installed between the industrial control network and the external network interconnection, and between the internal areas of the industrial control network to block all illegal access. Allow trusted traffic to travel on the network. However, the network security device itself may not work properly due to unexpected events such as power outages and system crashes. Therefore, in order to prevent the failure of the network security device and cause the entire communication system to be disconnected, a bypass function (Bypass) is usually set. [0003] The bypass function (Bypass) refers to the direct phys...
