Fig. 1 is the schematic flow sheet of the double hot standby method based on heartbeat of embodiment of the present invention.
As shown in Figure 1, a kind of double hot standby method based on heartbeat, comprises the following steps:
Step S1, connects the first fire compartment wall and the second fire compartment wall by heartbeat.
The first fire compartment wall and the second fire compartment wall are under consolidated network topological environmental, between the first fire compartment wall and the second fire compartment wall, be connected by heartbeat, and carry out the synchronous of configuration information to each other and data message by heartbeat every regular time interval (as 10 seconds), make them there is identical routed path.
Step S2, the first fire compartment wall is set weighted value to each routed path being associated with the first fire compartment wall, and the second fire compartment wall is set weighted value to each routed path being associated with the second fire compartment wall.
For identical routed path, the first fire compartment wall and the second fire compartment wall arrange different weighted values.In example embodiment, the first fire compartment wall and the second fire compartment wall have identical routed path, comprise routed path 1 and routed path 2, the weighted value of the first fire compartment wall routed path 1 is set to 50, the weighted value of routed path 2 is set to 30, the weighted value of the second fire compartment wall routed path 1 is set to 30, and the weighted value of routed path 2 is set to 40.
Step S3, the first fire compartment wall calculates the summation of the weighted value of all routed paths that are associated with the first fire compartment wall, and the second fire compartment wall calculates the summation of the weighted value of all routed paths that are associated with the second fire compartment wall.
In example embodiment, the routed path weighted value summation of the first fire compartment wall is that the routed path weighted value summation of 80, the second fire compartment walls is 70.

In example embodiment, the routed path weighted value summation of the second fire compartment wall that the first fire compartment wall is received is that the routed path weighted value summation of the first fire compartment wall of receiving of 70, the second fire compartment walls is 80.
Step S5, the first fire compartment wall and the second fire compartment wall compare respectively the routed path weighted value summation of self and the size of the other side's who receives routed path weighted value summation.
In example embodiment, the first fire compartment wall is larger by relatively determining the routed path weighted value summation of self, and the second fire compartment wall is less by relatively determining the routed path weighted value summation of self.
Step S6, the state of the fire compartment wall self that routed path weighted value summation is larger is set to aggressive mode, ARP broadcasting packet is processed and carried out data retransmission, and the state of the fire compartment wall self that routed path weighted value summation is less is set to passive suppression mode, does not process any message.
