Embodiment
To combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
As shown in Figure 3, there are 2 kinds of mode of operations in the Docsis terminal in this pattern:
Repeater mode
Under this pattern, the Docsis terminal provides the data path of transparent transmission for the HomePNA system, and the configuration at its terminal need be adopted transparent transmission (Transparent) template configuration.
The Transparent template is the data penetration transmission template, and data penetration transmission refers to packet and do not make any modification from getting into the terminal import to outlet, keeps original data format and transmits.
Terminal pattern
Under this pattern, the Docsis terminal directly is used for subscriber household inside, adopts traditional terminal to insert (Access) configuration template.
The Access template inserts template for the user, generally is to be used for dividing professional template, and the port of user terminal is furnished with the vlan mark of miscellaneous service respectively, distributes according to the business that the user is customized.
For the configuration of these two kinds of patterns, need to adopt automatic configuration method, the method that is detected the pattern of terminal operating and started Docsis local side distribution configuration command or configuration template by network management system realizes.
The application has described a kind of Docsis terminal template dynamic configuration method that triggers through HomePNA local side register flow path, and has described its corresponding system and device.
DOCSIS terminal and HOMEPNA terminal configuration flow process:
As shown in Figure 4, when the HomePNA local side starts, at first get into the HomePNA local side and start register flow path, send authentication request to access server (BRAS).In this process, the Docsis local side of its first line of a couplet provides authentication proxy's service, and message identifying is carried out transfer.The HomePNA local side is initiated authentication and is inserted request (Access request) to Docsis local side (authentication proxy).The authentication that DOCSIS local side (authentication proxy) receives the HomePNA local side inserts request (Access request); And message identifying carried out transfer; Send the request of inserting (Relay_Access request) to BRAS (Broadband Remote Access Server, BAS Broadband Access Server).BRAS starts identifying procedure and confirms with corresponding authentication response whether the HomePNA local side allows to insert according to the MAC Address of HomePNA local side.
For the HomePNA local side through authentication, BRAS sends to NM server to authentication result (the IP address that comprises the MAC Address and the first line of a couplet Docsis local side of HomePNA local side).
NM server sends configuring request through network management protocol to the Docsis local side, and this request only comprises that needs allow the MAC Address of the HomePNA local side of access.The Docsis local side is located the Docsis terminal equipment MAC Address of this HomePNA local side first line of a couplet and is sent configuration management message to this Docsis terminal through searching inner corresponding MAC Address mapping table.
The Docsis terminal is after receiving configuration management message, and the change mode of operation is a repeater mode, all messages of transparent transmission.
At this moment, the first line of a couplet path of HomePNA local side is all got through.Its corresponding first line of a couplet Docsis local side can send configuration successful message (Access_OK) to the HomePNA local side after the Docsis terminal gets into repeater mode.
The HomePNA local side gets into normal mode of operation after receiving configuration successful message, through carrying out alternately with NM server, revise the configuration at HomePNA terminal.
The HomePNA local side starts register flow path: the Docsis terminal that the HomePNA local side needs to confirm the first line of a couplet under the mode of operation of Mixed cascading has been operated in repeater mode, and then starts the EoC access service.Design is to start one section logic below adding in the flow process at it.It is as shown in Figure 5,
21) said HomePNA local side is closed the HomePNA port in the hardware initialization stage;
22) during said HomePNA local side transmitting apparatus authentication request, wait-for-response device authentication message, if authentification failure sends error message, and wait timeout sends after 30 seconds once more;
23) if authentication success is then intercepted the configuration successful message of step 14),, then send error message, and wait timeout gets into step 22 again after 30 seconds) if accept failure;
24) if accept successfully, then open the HomePNA port.
Webmaster is provided with HomePNA terminal flow process:
As shown in Figure 8; NM server sends configuring request through network management protocol to the HomePNA local side, and the HomePNA local side is searched the terminal equipment of the second line of a couplet, sends to the terminal equipment of the second line of a couplet according to the business demand template of webmaster transmission; When the success of second line of a couplet terminal configuration, terminal operate as normal.When the failure of second line of a couplet terminal configuration, the terminal can initiatively be sent Set_Error and given webmaster, waits for that webmaster resends.
Homepna terminal configuration flow process:
As two-layer equipment, the configuration at EoC terminal generally comprises two parts.The firstth, its corresponding communication protocol configuration, the secondth, the configuration of its Ethernet interface (speed limit, QoS mapping etc. are set like VLAN).The flow process of its configuration has the EoC local side to initiate, and the message of configuration adopts the form of two layers self-defined administrative message.Homepna administrative messag definition: the general mode that adopts two layers self-defined management agreement bag of management control message in the homepna system, the composition of its message content such as Fig. 6.
Lead code: constitute by the preamble of 7 bytes and the SFD of 1 byte
DA: target MAC (Media Access Control) address
SA: source MAC
TYPE: the type codes of Ethernet upper-layer protocol, for the privately owned management agreement of OM, generally can select a type codes that is not assigned with to be used, as be defined as 0x9990
DATA: the data message content of encapsulation OM type and administrative messag
FCS: frame check sequence
The type field of the privately owned administrative messag of OM TYPE:OM is generally used 1 byte representation
OM PAYLOAD: the content that encapsulates all OM administrative messags
TLV: a kind of mode that defines the administrative messag content, any one management project is made up of three fields, is respectively type (Type), and length (Length) and value (Value) abbreviate TLV as.For example, the type of definition terminal template is 1, and length is 1 byte, and value refers to the numbering of template type.
The collocation method at homepna terminal:
Configuration for the homepna terminal generally can be adopted following several method.
Dynamic-configuration: this collocation method is directly given the terminal distribution configuration command, and converts the control command word to by the terminal, is handed down to each system unit and comes into force then and there.The advantage of this method is not need restarting terminal device just can come into force, but shortcoming is the configure order information of not preserving, and all needs distribution configuration command again at every turn.
Preserve the collocation method of configuration order:
In order to overcome the shortcoming of Dynamic Configuration, hew out at the terminal one can be erasable memory space, be used for recording configuration order.When restarted at each terminal, the order of this configuration space can be issued to automatically in the corresponding system unit and come into force.It should be noted that; Because different system units adopts different configuration orders, the configuration order between the different vendor of same base part has very big difference, therefore; This method portable bad; In case the parts manufacturer at terminal changes, so corresponding configuration order all can need definition again, causes the difficulty of maintenance.
Preserve the collocation method that the configuration feature definition is described:
What this method was preserved is the description of configuration feature definition, rather than actual configuration order.The configuration order that this requires configurating terminal to go to resolve these configuration features and be converted into corresponding system unit.Because these are described and the producer of parts has no relation, conversion is all accomplished at terminal inner.Therefore the portability of system can be better.
Homepna administrative messag example:
For some administrative messags of mentioning in the preceding text, further the message definition example is following:
Docsis local side dynamic-configuration Docsis terminal flow process
As shown in Figure 7, NM server sends configuring request through network management protocol to the Docsis local side, and this request only comprises that needs allow the MAC Address of the HomePNA local side of access.The Docsis local side is located the Docsis terminal equipment MAC Address of this HomePNA local side first line of a couplet and is sent configuration management message to this Docsis terminal through searching inner corresponding MAC Address mapping table.The Docsis terminal is after receiving configuration management message, and the change mode of operation is a repeater mode, all messages of transparent transmission.At this moment, the first line of a couplet path of HomePNA local side is all got through.Its corresponding first line of a couplet Docsis local side can send configuration successful message (Access_OK) to the HomePNA local side after the Docsis terminal gets into repeater mode.When the failure of Docsis terminal configuration, the Docsis terminal can initiatively be sent Set_Error message and given webmaster, waits for that webmaster resends.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the present invention's design; Can also make some improvement and retouching, these improvement and retouching also should be regarded as in the protection range of the present invention.
