一种快速切换的网口Bypass系统
本技术属于工业防火墙领域,尤其涉及一种快速切换的网口Bypass系统。
技术介绍
网络安全设备一般都具有网口Bypass功能。现有网口Bypass系统或设备的主要功能元器件为继电器,通过继电器的开启与闭合来实现网口Bypass和非Bypass的状态切换,断电的情况下仍然能保持网络的连接功能。但是继电器的切换为物理切换,切换速度较慢且稳定性差。
技术实现思路
有鉴于此,为了克服现有技术的不足,本技术提供一种快速切换的网口Bypass系统,在保持了传统网口Bypass的全部功能外,大大的提高了网络的切换速度。为实现上述目的,本技术的技术方案如下:一种快速切换的网口Bypass系统,该网口Bypass系统包括CPU,所述CPU搭载PHY1和PHY2,所述PHY1与Transformer1相连接,所述PHY2与Transformer2相连接,所述Transformer1与LAN1之间连有AnalogSwitch1,所述Transformer2与LAN2之间连有AnalogSwitch2,所述LAN1和所述LAN2之间连有RelaySwitch, ...
