Fig. 2 is the IP application IP addresses message transmission processing flow chart of preferably implementing according to the present invention, and as shown in Figure 2, this flow process comprises following treatment step:
Step S202, network element electrifying startup.
Step S204, after network element powers on, checks whether network element IP address exists.If network element has IP address, enter step S212; If network element does not have IP address, put the application of the application's network element IP address and be labeled as 1, enter step S206.
Step S206, checks whether network element exists MAC Address.If there is no network element MAC Address, enters step S208; If there is network element MAC Address, enter step S210.
Step S208, according to the interim MAC Address of random algorithm generation network element, the MAC Address mark application of simultaneously putting the application's network element is 1.
Step S210, network element sends IP application IP addresses message.For example, application network element can send IP application IP addresses message to adjacent network element by this network element all of the port, wherein, carries the identification information (that is, the interim MAC of this network element MAC Address or this network element) of this network element of unique identification in this IP address message.Particularly, if do not receive the IP address assignment response message of this network element of IP address server transmission in T in interval time, this network element need to send this IP application IP addresses message again so.Fig. 3 is the form schematic diagram of the IP application IP addresses message preferably implemented according to the present invention, as shown in Figure 3, in specific implementation process, this IP application IP addresses message content can comprise: network element MAC (6 bytes), network element MAC application mark (1 byte) and network element IP application mark (1 byte).
Step S212, IP application IP addresses message sends and finishes.
In specific implementation process, in network, only have network element to be seldom directly connected with IP address server, can allow IP address server directly receive the IP application IP addresses message of its transmission, thereby acquisition IP address also arranges certainly, as IP trunk network unit, act on behalf of other network elements to IP address server application IP address.And most network element does not all have to be directly connected with IP address server, that is to say, need to be by above-mentioned IP relaying network element to IP address server application IP address.
Fig. 4 is the flow chart that the IP relaying network element preferably implemented according to the present invention forwards IP application IP addresses message processing procedure, and as shown in Figure 4, this flow process comprises following treatment step:
Step S402, network element receives the IP application IP addresses message sending to IP address server.
Step S404, checks whether this network element is IP relaying network element.If not IP relaying network element, directly abandon this application message, enter step S410; If IP relaying network element enters step S406.
Step S406, checks in IP application IP addresses table whether had identical network element MAC in IP application IP addresses state.If had, belong to duplicate message, directly abandon this message, enter step S410; If no, enter step S408.Fig. 5 is the IP application IP addresses tableau format schematic diagram of preferably implementing according to the present invention, and as shown in Figure 5, IP application IP addresses table can comprise: application network element MAC (6 bytes) and application port (6 bytes).This IP application IP addresses table can record it for IP relaying network element and act on behalf of which network element to IP address server application IP address, so that forward IP application IP addresses message and in response to the IP address assignment message of IP application IP addresses message.
Step S408, network element MAC and the receiving port information of preserving this IP application IP addresses message arrive IP application IP addresses table.
Step S410, forwards IP application IP addresses message by network layer communication to IP address server.
IP address server is after receiving the IP application IP addresses message of application network element transmission, according to each field implication in this IP application IP addresses message (, application mark) for application network element distributes the information such as network element MAC (if necessary), network element IP address, subnet mask, and (these assignment information are sent to IP address relaying network element, the application network element that gets IP address can self be set to IP relaying network element, to act on behalf of other network elements to IP address server application IP address).In specific implementation process, these address informations that IP address server can be distributed to application network element are kept in an IP address assignment table, and wherein, the information in IP address assignment table can also comprise IP address server address except address above mentioned.
Fig. 6 is the IP address assignment tableau format schematic diagram of preferably implementing according to the present invention, as shown in Figure 6, the content of IP address assignment table can comprise: network element MAC (6 bytes), network element IP type (1 byte), network element IP address length (1 byte), network element IP address (4 bytes) and the interim MAC of network element (6 bytes).Wherein, IP address server, when certain application network element distributes address information, for the content not having in IP address assignment table, can be filled out " 0 " or vacancy.For example, application network element, when sending IP application IP addresses message, has the MAC Address of oneself, and, without generating interim MAC Address, now, " the interim MAC of the network element " unit in IP application IP addresses table can be set to " 0 ".
Fig. 7 is the form schematic diagram of the IP address assignment message preferably implemented according to the present invention, IP address server can be carried at the address information of distributing to application network element in IP address assignment message, to send to the IP relaying network element in network, then is transmitted to application network element by IP relaying network element.As shown in Figure 7, IP address assignment message can comprise: application network element MAC (6 bytes), network element network MAC are (, IP address server is distributed to the new MAC of zero-address network element, 6 bytes), network element IP address type (1 byte), network element IP address length (1 byte), network element IP address (4 bytes), IP address server address style (1 byte), IP address server address size (1 byte) and IP address server address (4 bytes).
IP address relaying network element receives after the IP that IP address server is assigned to, according to the object network element MAC in IP address assignment message (that is, the identification information of application network element), check IP application IP addresses table, find corresponding outbound port, send this IP address information to respective network elements.If secondary IP address application form is searched the outbound port failure of application network element to it, directly abandon this IP address assignment message.
IP application IP addresses network element receives behind the IP address being assigned to, the IP address that need to enable to be assigned to.Particularly, first check whether the object MAC (that is, application network element MAC) in the assignment message receiving is the MAC of this network element.If not, so directly abandon; If so, preserve network element IP address and network element MAC information to nonvolatile devices, configuration of IP resource information is to network element, and operation comes into force.Meanwhile, record IP server address, it is IP relaying network element that this network element is set.
It should be noted that, if (this network element applied for network element MAC from IP server, before network element application IP address, there is no MAC, carry the interim MAC application IP address of random generation, by IP address server for it has distributed a new network element network MAC), so after above-mentioned flow process completes, also need to send request message to IP address server, for deleting the interim MAC of this network element of IP address assignment table, the MAC that this network element is assigned to comes into force, that is to say, for any one network element in network, to only have its address of a MAC of unique identification.
This preferred embodiment can be network equipment distributing IP address automatically, and in the situation that the network equipment does not have the basic configuration information of network communication, still can on secondary IP address server, obtain IP address information, realizes IP layer intercommunication.

Step S808, when the IP of network element 3 Address requests message arrives network element 2 again, network element 2 is relaying network elements, the IP Address requests message that network element 2 can forward network element 3 by network layer is to IP address server.In specific implementation process, network element 2 need to be registered this application information in IP application form, to forward and receive the IP address assignment message that IP server returns exactly, supposes it can is as information in following table.
| Application MAC | Application port | |
| Network element 3 | 1:1:1:1:2:3 | 3 |
Step S809, IP address server receives after the request of network element 3, is network element 3 distributing IP address informations, particularly, can be as following table.
| The address information of network element 3 | |
| Network element MAC | 1:1:1:1:1:3 |
| Network element IP address | 197.14.23 |
| Subnet mask | 255.255.255.255 |
| The interim MAC of network element | 1:1:1:1:2:3 |
Step S810, network element 3 receives after the address information that IP address server is network element 3 distribution, configures and enable relevant information, sends message and notices the interim MAC of IP address server deletion network element (for example, 1:1:1:1:2:3).
Step S811, other network element IP address application method the like, repeat no more.
