Gigabit Ethernet switch system based on 2FI+CTC5160 configuration

Abstract

The present invention discloses a gigabit Ethernet switch system based on 2FI+CTC5160 configuration. The system comprises a CPU subsystem, an Ethernet switch subsystem and a power supply subsystem; the CPU subsystem employs a Loongson 2FI as a processor, the external device interaction bus PCI of the Loongson 2FI and a Local Bus are employed to extend a PCIe, a management network internet access, a management serial port and an I2C interface required by a board card; the Ethernet switch subsystem employs CTC5160 as a switch chip; and the power supply subsystem is configured to convert the external 5VDC power supply and the 3.3VDC power supply to the required power supply of each device through a multi-level DC-DC. The gigabit Ethernet switch system based on 2FI+CTC5160 configuration enhances the information safety of the hardware level, reduces the potential safety hazard of the network information device as much as possible and improves the autonomous guarantee capability of the device.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a Gigabit Ethernet switching system based on 2FI+CTC5160 architecture, which is used for storage, transfer and exchange of network information in special fields. Background technique [0002] Information processing equipment is the main carrier for striving for information advantages and decision-making advantages in the information age. Information processing capabilities not only depend on the functions of information processing equipment, but also their independent support capabilities will directly affect comprehensive capabilities. Currently, the only information security capabilities mainly Relying on software methods such as firewalls and intrusion monitoring, there is almost no information security enhancement at the hardware level, and there are great security risks, making it difficult to meet the security and self-guaranteed requirements of the informatio...
