Description
Technical field
The present invention relates to the EPON of Optical Access Network, soft exchange local side and soft exchange field of terminal, and in particular to
Increase the method for DHCP Option82 fields in a kind of EPON system.
Background technology
Option is an option in DHCP message, and the option is the field of variable length, option in DHCP message
Partial charter party information, type of message etc. are contained in option.255 option can at most be included in option options, at least
For 1 option.
Option 82 is also known as relay agent information option (relay agent information option), is
A part for option contents in DHCP message.Option 82 defined in rfc3046, its position is before option 255
And after other option.Most 255 sub-option can be included in option 82, if defining option 82,
At least to define a sub-option.Commonly used in current option 82 be sub-option 1, sub-option 2,
Sub-option 3, sub-option 4 and sub-option 5, coded format is as follows.
Character string 1：{eth|trk}
Character string 2：NAS_slot/NAS_subslot/NAS_port:SVLAN.CVLAN
Character string 3：AccessNodeIdentifier/ANI_rack/ANI_frame/ANI_slot/ANI_subslot/
ANI_port/ONU_ID
Character string 4：[ONU_Slot/ONU_Subslot/Port_ID:{atm|eth}/Port_XPI.Port_XCI]
Character string 5：{EP|GP|XE|XG}
When dhcp client send request message to dhcp server, if desired by DHCP relay, then by DHCP
Option 82 is added in request message by relaying, to identify the positional information of user.
In the realization of current EPON system, it is desirable to which local side apparatus OLT and terminal device ONU serve as the angle of DHCP relay
Color, is required for adding respective option82 field contents in DHCP message, so, and DHCP message is needed by twice
Relaying, twice addition Option82 fields.
The content of the invention
The technical problem to be solved in the present invention is that the addition for Option82 fields in existing EPON system needs simultaneously
The deficiency of two trunkings is enabled there is provided the method for DHCP Option82 fields is increased in a kind of EPON system, use is simplified
The implementation of family line attachment (port) mark, it is more reasonable than the mode that former local side apparatus opens relay agent.
The technical solution adopted for the present invention to solve the technical problems is：
Increase the method for DHCP Option82 fields in a kind of EPON system, comprise the following steps：
S1, when terminal device ONU authorize reach the standard grade when, local side apparatus OLT by access line road (port) mark using expand
The location information OAM of exhibition is handed down to terminal device ONU；
S2, dhcp client initiate DHCP request message；
S3, when DHCP message is by terminal device ONU (terminal device ONU forward DHCP message), terminal device ONU
Dhcp relay feature is enabled, terminal device ONU carries out each field information got from local side apparatus OLT according to following form
Combine " AccessNodeIdentifier/ANI_rack/ANI_frame/ANI_slot/ANI_sub slot/ANI_port/
In ONU_ID " formation character strings, then the Option82 fields that the character string of combination is filled to DHCP request message are turned
Hair；
S4, when DHCP message pass through local side apparatus OLT when, local side apparatus OLT does not enable dhcp relay feature, does not also appoint
What is operated, direct transparent transmission DHCP message to Dynamic Host Configuration Protocol server.
By such scheme, in the step S1, privately owned OAM is configured between local side apparatus OLT and terminal device ONU, it is private
There is OAM to be used for the location information OAM that local side apparatus OLT issues privately owned extension to terminal device ONU.
By such scheme, the parameter of the location information OAM is specifically included：Access node (OLT) mark, access node machine
Frame number, access node frame number, access node groove number, access node pilot trench number, access node port numbers, ONU optical branch number.
By such scheme, the message format of the privately owned OAM uses the definition similar with telecommunication standard, whole message lattice
Formula is as follows：
By such scheme, in the message format of the privately owned OAM, Ext.Opcode action type is as follows：
| Extended operation code (Ext.Opcode) | It is worth (16 system) | Definition |
| Reserved | 0x00 | Ignore |
| Extended Variable Request | 0x01 | Same telecommunication standard |
| Extended Variable Response | 0x02 | Same telecommunication standard |
| Set Request | 0x03 | Same telecommunication standard |
| Set Response | 0x04 | Same telecommunication standard |
| Reserved for future use | Other values | Retain |
By such scheme, in the message format of the privately owned OAM, PayLoad is divided to for two parts, variable index and variable
Content, wherein variable index are made up of branch and leaf nodes, and variant content is by user-defined variable value
Filling, particular content is as follows：
By such scheme, variable index branch extended attributes are 0xC7 (extended attribute and operation to the various objects of ONU
Management, the branch codings of its Variable variable are identical with telecommunication standard), branch is defined as follows shown in table：
| Branch | context |
| 0xC7 | Custom Attributes |
| 0xC9 | Self-defining operation |
| other | resvered |
By such scheme, variable index leaf point spreads attribute and its code are as follows：
| Property Name | Description | Manage object | Leaf | Get | Set |
| ONU location informations | ONU location informations | ONU | 0x001b | It is | It is |
Wherein, the Payload specific field contents of ONU location informations are as follows：
The present invention has the advantages that compared with prior art：The present invention reduces the addition step of option82 fields
Suddenly, it is not necessary to all added successively by terminal and local side apparatus, and only need to once add completion on the terminal device, terminal device
Relay function is opened, local side apparatus transparent transmission, local side need not open relay agent, it is not required that do any operation, simplify use
The implementation of family line attachment (port) mark, it is more reasonable than the mode that former local side apparatus opens relay agent.
Brief description of the drawings
Fig. 1 is the OAM interaction figures between local side apparatus OLT and terminal device ONU in EPON system of the present invention；
Fig. 2 is the flow chart of the method for increase DHCP Option82 fields in EPON system in the embodiment of the present invention.
Embodiment
Below in conjunction with principle and feature further description of the accompanying drawing to the present invention, example is served only for illustrating this
Invention, and non-limiting application of the invention.
As depicted in figs. 1 and 2, the embodiment of the present invention provides increase DHCP Option82 fields in a kind of EPON system
Method, specific implementation step is as follows：
Step S1：When terminal device ONU, which is authorized, to reach the standard grade, local side apparatus OLT issues the positioning of extension to terminal device ONU
Information OAM；
ONU receives the OAM after mandate is reached the standard grade, and specific OAM is：
Step S2：Dhcp client initiates DHCP request message；
Step S3：ONU enables dhcp relay feature：When DHCP message passes through terminal device ONU, terminal device ONU will
The field got from local side apparatus OLT is combined " AccessNodeIdentifier/ANI_rack/ according to following form
ANI_frame/ANI_slot/ANI_subslot/ANI_port/ONU_ID " formation character strings, then by the character string of combination
Forwarded after filling to the Option82 fields of DHCP protocol message；
Step S4：When DHCP message passes through local side apparatus OLT, local side apparatus OLT does not enable dhcp relay feature, also not
Do any operation, direct transparent transmission DHCP message to Dynamic Host Configuration Protocol server.
It should be appreciated that for those of ordinary skills, can according to the above description be improved or converted,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
