Embodiment
Below in conjunction with each accompanying drawing, the main of embodiment of the present invention technical scheme is realized principle, embodiment and set forth in detail the beneficial effect that should be able to reach.
As shown in Figure 1, be a kind of redundancy backup swap method that the embodiment of the present invention provides, the method comprises the following steps:
Step 101, calculate the priority of standby routing equipment according to priority value corresponding to the parameter of standby routing equipment and weighted value corresponding to this parameter and user configured priority facility value;
Step 102, exceed the scheduled time do not detect main routing device send message time, standby routing equipment the highest for priority being switched is main routing device.
After redundancy backup swap device starts, for supporting the standby routing equipment configuration virtual IP address of redundant backup function, add virtual port.Then weighted value corresponding to priority value corresponding to the parameter of standby routing equipment, this parameter and user configured priority facility value is obtained, and then obtain the priority of this standby routing equipment, wherein, the priority value that parameter is corresponding and weighted value corresponding to parameter can obtain according to predetermined mapping table, concrete, value getparms, the codomain at the value determining this parameter place in the mapping table, then obtains priority value corresponding to codomain.When obtaining priority, calculate the priority of this standby routing equipment according to the product of priority value corresponding to the parameter of this standby routing equipment and weighted value corresponding to this parameter and user's configuration identifier and user configured priority facility value sum.Wherein, the priority value that the parameter of this standby routing equipment is corresponding specifically comprises: the value obtaining this parameter, and the codomain at the value determining this parameter place in the mapping table, obtains the priority value that this codomain is corresponding.If priority facility value that user is pre-configured, then the value of user's configuration identifier is 0.Difference as the case may be, can revise accordingly to above-mentioned acquisition formula.
The parameter of standby routing equipment includes but not limited to Center Processing Unit Utilization, standby routing equipment temperature.Because the parameters such as Center Processing Unit Utilization, standby routing equipment temperature are dynamic changes, therefore, the priority value of its correspondence can be determined according to the scope at the value place in its a certain moment.The weighted value that Center Processing Unit Utilization is corresponding is greater than weighted value corresponding to standby routing equipment temperature, and the priority value of Center Processing Unit Utilization lower than predetermined threshold time, the priority value of this standby routing equipment is set to priority minimum; When the weighted value that standby routing equipment temperature is corresponding is greater than weighted value corresponding to Center Processing Unit Utilization, and the priority value of standby routing equipment temperature lower than predetermined threshold time, the priority value of this standby routing equipment is set to priority minimum.The standby routing equipment be not suitable for as main routing device can be got rid of like this, and then determine that switching is the standby routing equipment of main routing device faster.If time identical according to multiple standby routing equipment priority of the gain of parameter of standby routing equipment, can according to the subrack at standby routing equipment place number and slot number determination priority.Subrack is number less, and standby routing equipment priority is higher, and when subrack is number identical, slot number is less, and standby routing equipment priority is higher.
Main routing device carries out information interaction with redundancy backup swap device in real time or regularly, when exceeding scheduled time redundancy backup swap device and not receiving the message of main routing device transmission yet, can judge that this main routing device quits work, now, standby routing equipment the highest for priority can be switched is main routing device.The out-of-work reason of main routing device can for main road broken down by equipment or the priority of main routing device lower than predetermined threshold value etc.
In addition, can also according to the time of delay of priority determination standby routing equipment, priority is higher, and time of delay is shorter, when terminating and the message that main routing device sends do not detected yet the time of delay of standby routing equipment, this standby routing equipment being switched is main routing device.Certainly, directly can specify that to switch be the standby routing equipment of main routing device, this main routing device continues transmission information between main control device and terminal management apparatus.When main like this routing device cannot normally work, it is main routing device that standby routing equipment can be switched in time, guarantees smooth transmission information between main control device and terminal management apparatus.

| The average occupancy of CPU | The priority value priority_cpu mapped |
| 90％～71％ | 0 |
| 70％～30％ | 25 |
| Less than 30% | 50 |
Namely according to the scope at the value place of CPU usage, the priority value that CPU usage is corresponding is determined.Numerical value more high priority is higher, and the numerical value in upper table and form are only an example, also can adopt other numerical value, the form that reach effect same.
The temperature of step 204, acquisition standby routing equipment, and obtain its priority value by mapping;
The temperature of standby routing equipment is also dynamic change, therefore, when calculating the priority value of its correspondence, can map according to following table:
Namely according to the scope at the value place of standby routing equipment temperature, the priority value that standby routing equipment temperature is corresponding is determined.Numerical value more high priority is higher, and the numerical value in upper table and form are only an example, also can adopt other numerical value, the form that reach effect same.
It should be noted that the step of the step obtaining standby routing equipment CPU usage and the temperature obtaining standby routing equipment does not have inevitable execution sequencing.
Step 205, obtain weighted value corresponding to the parameter of standby routing equipment;
The scope of each weighted value is as shown in the table:
| Weight | Codomain |
| Parameter 1weight1 | 1～5 |
| Parameter 2weight2 | 1～10 |
This weighted value can be configured by user, if do not configure, can within the scope of codomain random selecting value.
The priority value of step 206, calculating standby routing equipment;
priority＝user_set_priority+(priority_cpu*weightl+priority_temperature*weight2)*Flag
