Wherein, when the pattern sign instruction pattern be aggressive mode when, then the network equipment every preset duration to
Router sends the IP address of the network equipment；When the pattern of pattern sign instruction is Passive Mode, then network is set
It is standby to receive the address resolution protocol (English of router transmission：Address Resolution Protocol, referred to as：ARP)
After query message, then the IP address of the network equipment is sent to the router, whether which is used to inquire about needs to delete
Except the IP address of the network equipment.
In practical applications, the processing module of the network equipment sets the network equipment to be sent to router according to dormancy instruction
The pattern of IP address, and Remote Wake Up pattern is in by SES PHY chips, so that PHY chip can be in subsequent step
Wake up the network equipment.Electricity instruction under the processing module of the network equipment can also be sent to SES, is write lower electricity instruction by SES
The register of CPLD, and CPLD powers every preset duration to SES, so that the network equipment, which enters, treats wake-up states, only
There are the PHY chip and CPLD powered operations of the network equipment.
It should be noted that when the network equipment to router send IP address pattern be aggressive mode when, CPLD ability to
SES timing power supplies, if Passive Mode, then SES is also required to continued power operation, so as to after ARP query messages are received
Carry out response.
In step 202, the network equipment enters according to the dormancy instruction treats wake-up states.
Wherein, this treats that wake-up states can be resting state or off-mode.
In step 203, the network equipment be in treat wake-up states during, send the network equipment to router
IP address.
The IP address of network equipment aging in the route table items of router in order to prevent, is in the network equipment and waits to call out
During the state of waking up, the pattern indicated according to the dormancy instruction sends the IP address of the network equipment to router so that should
Router refreshes the route table items, and the route table items record after refreshing has the IP address of the network equipment, so as to ensure that network is set
Standby IP address will not aging.
Optionally, this step 203 can be replaced by step 2031 or step 2032：
Step 2031, every preset duration, the network equipment sends ARP messages to router.
When the pattern of the pattern sign instruction in the dormancy instruction that the network equipment receives is aggressive mode, the network
Equipment sends ARP messages every preset duration to router, which includes the IP address of the network equipment.
Wherein, which is usually 20 minutes, or other durations, the embodiment of the present invention do not limit this
It is fixed.
In addition, referring to table 1, the ARP messages that the network equipment is sent can not only include the IP address of the network equipment, such as table 1
It is shown, the MAC Address of the network equipment, and the hardware information and protocol information of the network equipment can also be included.
Table 1
Step 2032, according to ARP query messages generate arp response message, send the arp response message to router.
When the pattern of the pattern sign instruction in the dormancy instruction that the network equipment receives is Passive Mode, network is set
It is standby to send IP address to router without active, it need to only be sent out after the ARP query messages that receiving router is sent, then to router
Give the IP address of the network equipment.
It should be noted that each IP address recorded in route table items has ageing time, when some IP address exists
When duration arrival aging duration threshold value is stored in route table items, then route table items need to delete the IP address.Wherein, during the aging
Long threshold value is usually 20 minutes, or other durations, it is not limited in the embodiment of the present invention.
Correspondingly, when storage duration of the IP address in the route table items of router of the network equipment has reached aging duration
During threshold value, router first can send ARP query messages to the network equipment, to determine the need for deleting the network equipment
IP address.
Therefore, the ARP query messages that the network equipment can be sent with receiving router, and generated according to the ARP query messages
Arp response message, most after to router send the arp response message so that router refreshes according to the arp response message to be route
List item, then in route table items after refreshing, the storage duration of the IP address of the network equipment starts to clock again, so as to ensure
The IP address of the network equipment will not be deleted from route table items.
Wherein, which includes the IP address of the network equipment.
In step 204, router refreshes route table items according to the IP address of the network equipment of reception.
It is in the network equipment after wake-up states, the IP of the network equipment can be sent to router in a different manner
Location, and after router receives the IP address of the network equipment, then route table items can be carried out according to the IP address of the network equipment
Refresh so that the storage duration reclocking of the IP address of the network equipment in route table items, the route table items after refreshing continue
Record the IP address of the network equipment.
Wherein, the step of network equipment is to router transmission IP address is similar with step 202, and this will not be repeated here.
For example, the aging duration threshold value of route table items is 20 minutes, the IP address of the network equipment is in the route table items
Storage duration has also reached 20 minutes, then router needs to send ARP query messages to the network equipment, to judge that the network equipment is
It is no also in a network, if need to delete the IP address of the network equipment.The network equipment after the ARP query messages are received,
Generation includes the arp response message of the IP address of the network equipment, and the arp response message is sent to router, router root
Route table items are refreshed according to the arp response message so that the storage duration of the IP address of the network equipment is again since 0.
In step 205, remotely administered server sends to router and wakes up message.
When needing the network equipment to be in open state again to be worked, then remotely administered server can generate wake-up
Message, and the wake-up message is sent to router, so that router forwards the wake-up message to the network equipment so that network is set
It is standby from treating to be waken up in wake-up states.
Wherein, which is used to wake up the network equipment, which can be User Data Protocol (English：
User Datagram Protocol, referred to as：UDP) message, and it is packaged with magic packet voice in the UDP messages.
For example, with reference to table 2, the data filled in UDP messages are magic bag (English：Magic Packet) message, should
Magic packet voice is made of the FF codes and 16 identical MAC Address of 6 bytes, and in magic packet voice 16 it is identical
MAC Address is the MAC Address of the network equipment.
Table 2
In step 206, query router route table items obtain the IP address of the network equipment.
Referring to table 2, UDP messages include source port and destination interface, are forwarded in router to the network equipment and wake up message
When, it is necessary to obtain the corresponding destination interface of the network equipment, and the corresponding destination interface of each network equipment is and corresponding network
The IP address of equipment corresponds to, therefore can search corresponding destination interface according to the IP address of the network equipment, so as to be reported waking up
Text is sent to the network equipment.
Therefore, router after the wake-up message is received, it is necessary to according to the network equipment carried in the wake-up message
IP address, searches the IP address to match with the IP address in route table items.
In step 207, router forwards to the network equipment according to the IP address inquired and wakes up message.
After router inquires the IP address of the network equipment in route table items, it is possible to obtain the net according to the IP address
The corresponding destination interface of network equipment, sends the wake-up message so that the network is set finally by the destination interface to the network equipment
It is standby to be waken up.
In a step 208, the network equipment wakes up the network equipment according to the wake-up message of reception.
The network equipment be in after wake-up states, then the network equipment receive by remotely administered server produce and by
During the wake-up message of router forwarding, you can waken up the network equipment according to the wake-up message.
Specifically, after the network equipment receives the wake-up message, that is to say after receiving the UDP messages, and to the UDP
Message is parsed, and magic packet voice is obtained by parsing the UDP messages, then identify the magic packet voice carry 16 it is identical
