The invention provides a bypass protection device and method. The device is connected between network equipment and an Ethernet and comprises at least one pair of Ethernet interfaces, an electronic switch, a relay and a switch control unit, wherein the electronic switch corresponds to a first Ethernet interface and is connected with the first Ethernet interface and a first PHY (Physical Layer) chip of the network equipment, and a first transformer is arranged between the first Ethernet interface and the first PHY chip and located between the first Ethernet interface and the electronic switch; the relay corresponds to a second Ethernet interface and is connected with the second Ethernet interface and a second PHY (Physical Layer) chip and is directly connected with the first Ethernet interface; and the switch control unit is used for providing a control signal to the electronic switch and the relay, when the network equipment is normal, the first Ethernet interface is connected with the first PHY chip, and the second Ethernet interface is connected with the second PHY chip, and when the network equipment goes wrong or is power down, the first Ethernet interface is connected with the second Ethernet interface. The bypass protection device occupies small area, and the bypass protection method is used for realizing bypass protection with low cost.
Description
technical field [0001] The present invention relates to the technical field of communications, in particular to a bypass protection device and method. Background technique [0002] Network security devices are generally applied between two or more networks, such as between an intranet and an extranet. The application program in the network security device analyzes the network packets passing through it to determine whether there is a threat. After processing, the packet will be forwarded according to certain routing rules. If the network device fails, such as power failure or crash, then all network segments connected to this device will lose contact with each other. At this time, if necessary Each network still handles the connected state, which needs to be realized through a bypass protection (bypass) set between the network security device and the network. Bypass is to allow two networks that do not pass through the network security device to be directly physically conn...
