Meanwhile, reply arp reply message.Following content and will be to receiving ARP request message in the embodiment of the present invention two
The condition of device replied APR response messages elaborates.
In a kind of specific implementation of the invention, the IP address of subnet mask and the first equipment according to setting determines network
Number mode can be in the following manner（1）Or mode（2）：
Mode（1）Number of bits in the network position of the corresponding subnet mask of the IP address of the first equipment is less than setting
During the number of bits of the network position of subnet mask, the first equipment determines the network of each subnet according to the subnet mask of setting
Number, wherein each subnet is that the network of the IP address mark of first equipment is divided to obtain.
In specific implementation, the number of bits of the subnet mask of setting can be 24, certainly, the subnet mask of setting
Number of bits can also be other digits, set it to 24 simply in specific implementation of the embodiment of the present invention
Optional implementation method.
Alternatively, the network that the IP address of the first equipment is identified is divided into 2 by the first equipmentm-nIndividual subnet；Wherein, m is to set
The number of bits of network position in fixed subnet mask, n is the network position of the corresponding subnet mask of IP address of the first equipment
Number of bits.
In this fashion, when the corresponding subnet mask of the IP address of the first equipment network position number of bits compared with
It is few, and the number of bits of main frame position it is more when, show that the user of the network coverage that the IP address of first equipment is identified sets
Standby quantity is more, if all these user equipmenies all reply arp reply message after ARP request message is received, can be in short-term
It is interior that larger burden is come to the network bandwidth and first equipment belt.By setting a subnet mask in the embodiment of the present invention,
In the net of the number of bits less than the subnet mask of the setting of the network position of the corresponding subnet mask of the IP address of the first equipment
During the number of bits of network position, the network that the IP address of first equipment is identified is divided into multiple subnets, it is determined that with setting
The network number of corresponding each subnet of subnet mask, the network number of each subnet that will be determined respectively is sent out as purpose IP address
Send ARP request message；Correspondingly, the second equipment can after ARP request message is received, by the IP address of the second equipment with set
Fixed subnet mask carries out logic and operation and determines network number, it is determined that network number with receive ARP request message purpose
When IP address is identical, arp reply message is replied, using this sample loading mode, the first equipment receives the quantity of arp reply message every time
Greatly reduce, can effectively alleviate the operation caused to the pressure of the network bandwidth and to the first equipment in the short time and bear.Name
One specific example is described：
Such as, it is assumed that the IP address of the first equipment is 192.168.10.1, with being represented in binary as
11000000.10101000.00001010.00000001, the binary digit of the network position of the corresponding subnet mask of the IP address
Number is 16, i.e., with binary representation, the subnet mask is 11111111.11111111.00000000.00000000, then the IP
The network number of the network that address is identified is 192.168.0.0, and the number of bits of the network position of the subnet mask for setting is 24
Position, with binary representation, the subnet mask for setting is 11111111.11111111.11111111.00000000；Sending
During ARP request message, can be according to the subnet mask of setting, it is determined that the network that 192.168.0.0 this network number is identified
When being divided into multiple subnets, the network number of each subnet, here, the network number of each subnet is the subnet mask of correspondence setting
Network number, i.e. in the network number of subnet non-zero number of bits be equal to setting subnet mask network position binary digit
Number, here, the network position according to setting is the subnet mask of 24, it is possible to the net for being identified network number 192.168.0.0
Network is divided into 224-16=256 subnets, the network number of each subnet be respectively 192.168.0.0,192.168.1.0,
192.168.2.0 ... 192.168.255.0, afterwards, it is possible to using the network number of each subnet as ARP request message mesh
IP address, send ARP request message；IP address is receiving purpose IP address for second equipment of 192.168.20.1
192.168.20.0 after ARP request message, the second equipment by the IP address 192.168.20.1 of the second equipment with setting net
Network position determines that network number is 192.168.20.0 after carrying out logic and operation for the subnet mask of 24, with ARP request message
Purpose IP address are identical, and the second equipment sends arp reply message to the first equipment.
If use to enter row constraint to the equipment for replying arp reply with upper type, each receives setting for ARP request message
It is standby, arp reply message is all replied, most 65536-3 arp reply messages will be received in the first equipment short time, wherein subtracting
The 3 IP address respectively host number for going is full 0（Map network number）, full F（Correspondence broadcast address）IP address, and originally connect
The IP address of mouth.And use with upper type, the corresponding network number of subnet mask of 16 network positions is divided into 256 24 nets
The corresponding network number of subnet mask of network position, for the subnet mask that each network position is 24, the first equipment short time is interior most
Receive only 256 arp reply messages more, alleviate the fortune caused to the pressure of the network bandwidth and to the first equipment in the short time
Row burden.
It should be noted that the second equipment can independently determine whether that the first equipment sends arp reply message.Specific
In implementation, the second equipment can use and judge whether to send arp reply message to the first equipment with upper type, it is also possible to not use
Judge whether to send arp reply message to the first equipment with upper type.Such as, can be after ARP request message be received directly
Arp reply message is replied, can also be it is determined that the source IP address of ARP request message and the IP address of the second equipment belong to same net
Arp reply message is replied during section, the source IP address of ARP request message and the IP address category of the second equipment can also be at the same time met
In the same network segment, and, the IP address of the second equipment is carried out the network number of logic and operation determination with the subnet mask of setting, with
During identical the two conditions of the purpose IP address of the ARP request message of reception, arp reply message is replied.
Mode（2）：It is not less than in the number of bits of the network of the corresponding subnet mask of the IP address of the first equipment and sets
During the number of bits of the network position of fixed subnet mask：
The IP address of the subnet mask of setting and the first equipment is carried out logic and operation by the first equipment, determines network number.
In this fashion, when the corresponding subnet mask of the IP address of the first equipment network position number of bits compared with
It is many, and main frame position number of bits it is less when, show that the number of user equipment of the network coverage that the IP address is identified is less,
At this moment, it is not necessary to worry that all these user equipmenies all reply arp reply message after ARP request message is received, can be short
Carry out the problem of larger burden in time to the network bandwidth and first equipment belt, therefore, in such a case, it is possible to directly will
The IP address of the subnet mask of setting and the first equipment carries out logic and operation, determines network number.Name a specific example
Son is described：
Such as, it is assumed that the IP address of the first equipment is 192.168.10.1, with being represented in binary as
11000000.10101000.00001010.00000001, the binary digit of the network position of the corresponding subnet mask of the IP address
Number is 24, and the number of bits of the network position of the subnet mask for setting also is 24, then be with network position by the IP address
Every of the subnet mask 11111111.11111111.11111111.00000000 of 24 carries out logic and operation, it is determined that making
For the network number of the purpose IP address of ARP request message is 11000000.10101000.00001010.00000000（Correspondence ten
System 192.168.10.0）.Correspondingly, the second equipment is after the ARP request message is received, can use with it is above-mentioned the first
The similar mode introduced in mode judges whether to reply arp reply message, such as：
Directly arp reply message can be replied after ARP request message is received；
Can also be replied when it is determined that the source IP address of ARP request message and the IP address of the second equipment belong to the same network segment
Arp reply message；
The IP address of the source IP address and the second equipment that can also at the same time meet ARP request message belongs to the same network segment,
With, the IP address of the second equipment is carried out the network number of logic and operation determination with the subnet mask of setting, please with the ARP for receiving
When seeking identical the two conditions of purpose IP address of message, arp reply message is replied.
Alternatively, in S101, the first equipment sends ARP request message, including：
First equipment periodic sends ARP request message；And/or,
First equipment sends ARP request message when it is determined that the IP address of the first equipment changes.
In the embodiment of the present invention, the first equipment just sends ARP request message when IP messages are also not received by.Specific
