2, packet parsing module, the message that packet parsing module parses network-driven module is received, with information stores in its database and send to real-time library module.The packet parsing module sends confirmation message must could for after information has sent to real-time library module direct-connected device, the message handled does not have enough time after switching like this, the network retransmits information that direct-connected device can connect after switching is finished, so can drop-out, but can't guarantee that data are not multiple at this level.
3, real-time library module (real-time data base), the Data Source in the real-time data base is the event data that the packet parsing module produces, when monitoring server generation working net and the switching of standby net, the information that does not store in the real-time data base can be lost.
As seen from the above analysis, under the prior art processing method, the two net switching of working net and standby net hourglass is sent out, multiple data are inevitable, its reason is, for the communication protocol that does not have affirmation mechanism, in case taking place, two nets switch, the network-driven module can't realize the breakpoint transmission of data.
