In this enforcement new embodiment, when gateway system broke down or artificially switch, first by-pass switch and second by-pass switch all switched to its pin 2 positions, made and formed a loop between first network port and second network port.
In this enforcement new embodiment, have multiple for the implementation method of the control of described first by-pass switch, second by-pass switch and the 3rd by-pass switch.
Wherein, a kind of is the opening and closing that realize by-pass switch by the power supply triggering mode.Do not have at equipment under the situation of energising, bypass functionality is opened, if equipment is in case after the energising, bypass is adjusted into closed condition immediately.
Wherein, a kind of is to adopt GPIO (General Purpose Input OutputGPIO, general I/O) chip, can come specific port operation by GPIO, thereby realization is to the control of by-pass switch.
Wherein, a kind of is the opening and closing of adopting the described by-pass switch of house dog (WatchDog) chip controls, and can constantly send and return detection signal by Control Software, judges whether unusual.All just often then the by-pass switch data message that switches to 3, two network interface cards of pin handle and circulation by server self; When server occurs when unusual, then Bian Yi Control Software will send a signal to WatchDog, makes WatchDog open bypass functionality, and described first by-pass switch and second by-pass switch all switch to pin 2, realize the seamless switching of network, ensure the unobstructed operation of network.
The mode that also can adopt above-mentioned GPIO chip and WatchDog chip to combine is controlled enabling and closing of GPIO bypass procedure by WatchDog, realizes the opening and closing of by-pass switch.
Embodiment two
As shown in Figure 2, a kind of gateway device structural representation of providing for the utility model of Fig. 2.Be with embodiment one difference, also be provided with the 3rd by-pass switch between described first, second by-pass switch.The pin 3 of described the 3rd by-pass switch is connected with the pin 2 of first by-pass switch, and the pin 1 of the 3rd by-pass switch is connected with the pin 2 of second by-pass switch.
