Mode ByPass is ( skip mode or bypass mode ), refers to a system of normal flow in, a pile of nuclear detection mechanism, "ByPass Mode" is that when the mechanism of nuclear abnormality detection can not be excluded in a short period, so that the system can work around these nuclear inspection mechanism, the operating mode of the system can continue to run.

 

Application examples editor

1. For example, the fee ( monthly fee or reward card) of the online game , when the game time to compensate the official number of the player's game, you can open the "ByPass Mode" within a specific time, to bypass the login mechanism game or monthly fees check the balance of nuclear mechanisms reward card. Still in use in the game account, you can avoid deduction of points or the number of days to log into the game online games.
2. For example, in a well-known system chaotic transit system, occurs when the system returns the track on the obstacles, but after the actual inspection of the track when the system did not find the so-called obstacles, the system administrator can manually open the "ByPass Mode" the system continues to operate.

The difference between the gateway mode / bridge mode / bypass mode as follows:

EG device has three modes: mode gateway, bridge mode and a bypass mode, the gateway is the more common mode and bridge mode.

• Gateway mode is the network equipment as export support deployment of packet forwarding and routing under NAT routing.
• Bridge mode is the device as a bridge, deployment series core switches between the internal network and external network gateway exports.

 

 

Bridge mode into three kinds, namely forward / sniffer / bypass.

forward: audit of the traffic may be forwarded packet, application identification, by blocking the flow control.

sniffer: can be applied to identify forward packets, traffic audit.

bypass: the message is not processed directly forward.

• Bypass mode may be applied to identify the packets, only the packets received without forwarding.

 

2 is actually a way to effect a switch, in Bypass mode, the signal from the input interface directly without going through the effector circuit directly outputs to the output interface that the connection can be reduced to very low signal loss, because of this effect by the interface circuit, the switching path only a very tiny impedance in the signal.
