Specific embodiment
The very poor problem of the suitability present in upgrade method for existing VSU system, the embodiment of the present invention provides one
Plant the upgrade method of VSU system, VSU system includes main frame and slave, separately below with slave and main frame for executive agent introduction
The upgrade method of VSU system.
When executive agent is for slave, the flow process of the upgrade method of this VSU system is as shown in Fig. 2 execution step is as follows：
S21：After receiving the first upgrade command of main frame transmission, close its in addition to double Host Detection ports on slave
Its port, other ports include first line of a couplet port, second line of a couplet port and VSL port.
In VSU system, it is all generally that upgrade command is sent to slave from main frame, this upgrade command is defined as the first upgrading
Instruction.
In prior art, during VSU system upgrade, main frame and slave are not turned off any port, and in present example,
After slave receives the first upgrade command, the other ports outside double Host Detection ports can be closed out, as shown in Figure 1 it is assumed that S2
It is slave with S4, then the first line of a couplet port of S2, S4 is the port being connected with S5, S6, the second line of a couplet port of S2 is the port being connected with P1,
The second line of a couplet port of S4 is the port being connected with P2.
S22：Upgraded according to the upgraded version obtaining in advance and shadow configuration file, shadow configuration file only with original
Internet protocol (Internet Protocol, the IP) address that configuration file includes is different.
Need before VSU system upgrade to obtain shadow configuration file and upgraded version, shadow configuration file is exactly a independent
Configuration file, the unique difference from original configuration file of slave is exactly that IP address is different, and other information is just as.
When VSU system is more, can be, but not limited to preserve upgraded version using single upgrade server and shadow is joined
Put file, VSU system actively can obtain upgraded version and shadow configuration file it is also possible to by upgrade service from upgrade server
Upgraded version and shadow configuration file are pushed to VSU system by device, and wherein, main frame only need to obtain upgraded version, from confidential acquisition
Upgraded version and shadow configuration file.
Slave is upgraded according to upgraded version and shadow configuration file, due to shadow configuration file and original configuration file
Including IP address different, therefore, after slave upgrading, be equivalent to an independent equipment, be not and main frame composition VSU system
System.
S23：Open after first line of a couplet port carries out route learning, the first business is arranged by double Host Detection ports and main frame and cuts
Change the time.
In order to ensure after slave upgrading can to need to open first line of a couplet port after slave upgrading and route with normal process business
Study, after the completion of convergence, made a reservation for for the first business switching time by double Host Detection ports with main frame.
First business switching time referred to the time of main frame and slave service switchover, in order to ensure that business do not interrupt, first
Business switching time is at least accurate to Millisecond.
S24：Monitor after the first business switching time expired, open second line of a couplet port, take over the business of execution mian engine changeover,
So that main frame is upgraded according to upgraded version and original configuration file.
After the completion of slave upgrading, monitor after the first business switching time expired, slave opens second line of a couplet port, main frame is by industry
Business is switched to slave execution, and main frame starts to upgrade.
S25：After main frame upgrading, arranged for the second business switching time by double Host Detection ports with main frame.
In order to ensure that main frame and slave set up VSU system, after main frame upgrading, slave needs again according to original configuration file
Restart, at this moment need slave to pass through double Host Detection ports and made a reservation for for the second business switching time with main frame.
S26：Monitor after the second business switching time expired, the business of slave is switched to main frame execution.
S27：After restarting according to original configuration file, open VSL port, set up VSU system with main frame.

Slave can open VSL port, is successfully established VSU system with main frame, thus realizing the upgrading of VSU system.
In the program, because shadow configuration file when slave is upgraded is different from the IP address that original configuration file includes,
Be equivalent to another independent equipment it is not necessary to heat adds VSU system it is not required that carrying out hot standby cutting with main frame after slave upgrading
Change it is possible to be followed by the business for execution mian engine changeover in upgrading, then main frame starts to upgrade, after the completion of main frame upgrading, from
Business is switched to main frame by machine again, and slave is restarted afterwards further according to original configuration file and VSU system set up by main frame, this VSU system
Escalation process is not limited by original version and upgraded version, even if original version is widely different with upgraded version, also ensures that
VSU system is successfully upgraded, and the suitability is very good.
Specifically, the realization upgraded according to the upgraded version obtaining in advance and shadow configuration file in above-mentioned S22
Process, specifically includes：Loading upgrading version；Restart；Load shadow configuration file.
After slave gets upgraded version and shadow configuration file, it is shadow configuration file in order to ensure load after restarting
Rather than original configuration file, shadow configuration file and original configuration file can be saved under same path, and by shadow
Configuration file is named as the name of original configuration file, after the completion of loading, can delete shadow configuration file, and recover original and join
Put the name of file.
Specifically, the realization arranging for the first business switching time by double Host Detection ports and main frame in above-mentioned S25
Process, specifically includes：By double Host Detection ports to main frame tranmitting data register signal synchronization request；Receive main frame transmission when
After clock signal syn ack, send the provisioning request carrying for the first business switching time to main frame；The agreement that Receiving Host sends
Response.This process is equally applicable to arrange for the second business switching time.
Because main frame arranged for the first business switching time with slave, so ensure that main frame and slave enter industry simultaneously
Business switching, thus ensure that business is not interrupted.
When executive agent is for main frame, the flow process of the upgrade method of this VSU system is as shown in figure 3, execution step is as follows：
S31：After receiving the second upgrade command, send the first upgrade command to slave, so that slave is according to obtaining in advance
Upgraded version and shadow configuration file upgraded.
