Abstract
The invention discloses a DHCP (dynamic host configuration protocol)-option-message-based automatic configuration method for a network access device. Network configuration information is carried in a specific option field of a DHCP report, in the process of completing address request in a network management channel of the network access device, and configuration information required b a broadband access server to be completed by the device is sent to the network access device by DHCP messages to achieve automatic configuration of the network access device. Authentication and configuration submission of the network access device are achieved at one time quickly and efficiently. Configuration submission is quick and stable, and the network access device automatically generates corresponding configuration according to the configuration information in option messages. The broadband access server can be given to guarantee uniformity of the configuration information of the network access device in a certain area, and management is convenient for an operator.
Description
Technical field
The present invention relates to the broadband access field, relate in particular to a kind of network access equipment method of automatic configuration based on DHCP Option message.
Background technology
In the broadband access field, because number of users is huge, the not equal combined cause of each regional fixed network environment, cause the configuration information of terminal access device varied different.For terminal access device manufacturer, just need to be for the different software versions that configure of terminal access device exploitation in different areas, increase undoubtedly a large amount of job costs, and in a single day the situation of configuration error has occured, may cause the large tracts of land user can't normally use the situation of broadband services.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of network access equipment method of automatic configuration based on DHCP Option message, in the specific Option field that network configuration information is carried at the DHCP message, finish in the process of Address requests at the network management path of network access equipment, the configuration information that needs equipment to finish the width access server sends to network access equipment by dhcp message, to finish the automatic configuration of network access equipment.
For achieving the above object, a kind of network access equipment method of automatic configuration based on DHCP Option message of the present invention may further comprise the steps:
Determine that BAS Broadband Access Server and network access equipment all support based on the automatic condition of configuration of the network access equipment of DHCP Option message;
Network access equipment sends and comprises the DHCP Discover message that the Option field is carried unique authentication ID;
BAS Broadband Access Server receives the coupling that DHCP Discover message authenticates ID;
If coupling is correct, then the configuration information with the network access equipment of position, this area is encapsulated in the specific Option message, and sends to network access equipment by DHCP Offer message;
Otherwise, then abandon this DHCP Discover message;
Network access equipment receives with DHCP Offer message and analyzes the Option information wherein carry configuration information whether mate and finish;
If this network access equipment has been finished the coupling of above-mentioned configuration information, then directly use the address of distributing, need not to be configured work;
Otherwise, then receive first the address of distributing, finish configuration according to server requirement again.
Preferably, described Option message refers to the Option field in the DHCP message, a plurality of options of portability, first byte of each option is message code, thereafter byte be this item number according to length, be the contents of a project at last.
Preferably, described configuration information refers to various types of services of required configuration in the network access equipment.。
Beneficial effect of the present invention is:
1, the disposable network access equipment of finishing authenticates and configuration distributing work, rapidly and efficiently;
2, the configuration distributing process is fast stable, and network access equipment generates corresponding configuration automatically according to the configuration information in the Option message;
3, can give BAS Broadband Access Server, guarantee the uniformity of configuration information of the network access equipment in somewhere, make things convenient for the management of operator.
Description of drawings
Fig. 1 is the concrete steps figure of the method for the invention.
Embodiment
The present invention will be further described below in conjunction with Figure of description.
The described a kind of network access equipment method of automatic configuration based on DHCP Option message of the embodiment of the invention, by the specific configuration information of encapsulation in DHCP Option message, be issued to network access equipment by BAS Broadband Access Server, to finish the automatic configuration of network access equipment.
DHCP Option message refers to the Options field in the DHCP message, it allows producer self-defined, to realize more configuration feature, its variable-length, the a plurality of options of while portability, first byte of each option is message code, thereafter byte be this item number according to length, be the contents of a project at last.Operator need to carry out strict difinition to each field that needs in the DHCP Option message to use, with correctness and the uniqueness of guaranteeing that configuration information issues.
As shown in Figure 1, the concrete steps of the method are:
1, determines that BAS Broadband Access Server and network access equipment all support based on the automatic condition of configuration of the network access equipment of DHCP Option message;
2, network access equipment sends and comprises the DHCP Discover message that the Option field is carried unique authentication ID;
3, BAS Broadband Access Server receives the coupling that DHCP Discover message authenticates ID;
If coupling is correct, then the configuration information with the network access equipment of position, this area is encapsulated in the specific Option message, and sends to network access equipment by DHCP Offer message;
Otherwise, then abandon this DHCP Discover message;
4, network access equipment receives with DHCP Offer message and analyzes the Option information wherein carry configuration information whether mate and finish;
If this network access equipment has been finished the coupling of above-mentioned configuration information, then directly use the address of distributing, need not to be configured work;
Otherwise, then receive first the address of distributing, finish configuration according to server requirement again
In the above-mentioned method of mentioning, be sent to by network access equipment in the DHCPDiscover message of BAS Broadband Access Server and should comprise following a plurality of Option message, the deploy content that these message should comprise the exclusive authentication ID in local terminal, need to finish, by DHCP Discover message with the legitimacy of self and need to finish which configuration and inform BAS Broadband Access Server.
In the above-mentioned method of mentioning, configuration information refers to various types of services of required configuration in the network access equipment, as: access to the Internet, IP phone service, Internet Protocol Television service etc., and these serve employed particular network link sign (being generally VLAN ID or PVC).
Above; be preferred embodiment of the present invention only, but protection scope of the present invention is not limited to this, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range that claim was defined.
