When being similar to the ply-yarn drill that ply-yarn drill 1 and ply-yarn drill 2 are connected two switching networks simultaneously, when ply-yarn drill N sent message, ply-yarn drill 1 still can send to switching network A and switching network B to the different packet (load sharing) that sends to ply-yarn drill N as ply-yarn drill 1.
1) for the message that sends to switching network A, switching network A directly sends on the ply-yarn drill N by searching pre-configured transmitting, as shown in Figure 4, ply-yarn drill 1 sends to message by the port one of ply-yarn drill 1 port one of switching network A, switching network A is by searching the destination address of this message, be found to be ply-yarn drill N, then the port N by switching network A is forwarded to ply-yarn drill N with this message.
2) send to switching network B if ply-yarn drill 1 mails to the message of ply-yarn drill N, switching network B issues switching network A by searching pre-configured transmitting from port N+1, and switching network A searches pre-configured transmitting by port N again and sent to ply-yarn drill N, as shown in Figure 5.
Repeating process after active and standby switching network switches is revised as:
When ply-yarn drill N interrupts being communicated with changing into being communicated with of switching network A with switching network B, as: when main with switching network A with when switching with switching network B, be that switching network B becomes the main switching network of using, and switching network A becomes from switching network, at this moment for ply-yarn drill 1 and not influence of ply-yarn drill 2, and ply-yarn drill N is communicated with by switch and switching network B and and switching network A fracture, following Fig. 6.
During switching, by the repeating process on configuration modification switching network A and the switching network B.For switching network A, send to the message of ply-yarn drill N from port N in the repeating process and be revised as: the message to the N of ply-yarn drill sends to switching network B from port N+1.For switching network B, send to switching network A to the message of ply-yarn drill N from port N+1 in the repeating process and be revised as: the message to the N of ply-yarn drill sends to ply-yarn drill N from port N, is illustrated in fig. 7 shown below.
Revise by repeating process like this, switch the similar of processing procedure between the ply-yarn drill of back and front, the processing of ply-yarn drill does not change, and just the processing on the switching network A exchange B is different.
