System for realizing multi-IP address network isolation in equipment and application method

Abstract

The invention discloses a system for realizing multi-IP address network isolation in equipment and an application method, and the system comprises a CPU module which is provided with a first MII interface; a FPGA which is in communication connection with the CPU module through an AD bus and a first MII interface, wherein the FPGA is respectively connected with different IP addresses, service portsof different network segments and a network management port through a second MII interface and a third MII interface on the FPGA; and a first PHY chip and a second PHY chip are respectively arrangedbetween the FPGA and the service port and between the FPGA and the network management port. According to the system for realizing multi-IP address network isolation in the equipment and the application method thereof, through comprehensive utilization of the CPU and the FPGA, two Ethernet interfaces are provided in cooperation with the first PHY chip and the second PHY chip to be respectively usedfor carrying out sub-channel type communication with a service port and a network management port, so that network isolation of service and network management communication is realized. And independent use of a plurality of Ethernet interfaces is realized in the equipment.

Description

technical field [0001] The invention relates to a network isolation method. More specifically, the present invention relates to an IP address network isolation system strategy and application method after the MII port of the internal CPU of the device is configured with multiple IP addresses. Background technique [0002] In some specific network environments, the device needs to have multiple Ethernet interfaces, but in the prior art, the situation of having multiple network interfaces for network isolation is usually used on different devices, so through different devices The business and network management between the two can be independent of each other without affecting each other, but if this situation is used on the same device, that is, under the same CPU, the superiority of multiple network interfaces cannot be reflected, that is, in the same Under the CPU, its services and network management cannot be transmitted in isolation. After connecting to the network, the ...

[0002] In some specific network environments, the device needs to have multiple Ethernet interfaces, but in the prior art, the situation of having multiple network interfaces for network isolation is usually used on different devices, so through different devices The business and network management between the two can be independent of each other without affecting each other, but if this situation is used on the same device, that is, under the same CPU, the superiority of multiple network interfaces cannot be reflected, that is, in the same Under the CPU, its business and network management cannot be transmitted in isolation. After connecting to the network, the CPU will suffer from a network storm due to the inability to isolate data, which makes the stability of the device operation poor.

Therefore, when there are multiple Ethernet interfaces on the same device, network isolation and data distribution cannot be realized, so the independent use of multiple Ethernet interfaces on the same device cannot be realized.
