Embodiment
Below with reference to specific embodiment technical scheme provided by the invention is elaborated, should understands following embodiment and only be used for explanation the present invention and be not used in and limit the scope of the invention.
The authentication bootstrap technique of realizing the broadband restriction based on DNS provided by the invention mainly comprises three steps: distribute limited broadband address field; Limited broadband user is controlled; For limited broadband user realizes guiding push function.
Wherein, distributing address, limited broadband step is the basis of back two steps, and its main process is as follows:
At present, the user will use limited broadband services, must be through the special step of opening, the mode that provides at present has the business hall manually to open, phone is opened and three kinds of modes of network opening, limited broadband services is once open-minded, and then user's terminal network access device MAC Address is added in the limited broadband user MAC tabulation.Secondly, be required to be limited broadband user and set and be used for the special address field that distributes, be i.e. limited broadband address field.
Under the existing C MTS access way, send the interactive TV service request by set-top box, be built-in with cable modem in the set-top box as the terminal network access device, realize consumer wideband online demand.When the user sends the DHCP request, write specific set-top box information field at option60, the MAC field that can have cable modem among the option82 according to the standard of Docsis automatically: when the user sends the interactive TV service request by set-top box, write unified option60 field in option60, this field is pre-configured in the DHCP system; When the user by built-in cable modem(or cable modem independently) when sending limited broadband services demand, by the MAC Address that can have network access equipment among the standard option82 of Docsis---be the MAC Address of cable modem here.Under the CMTS access way, original DHCP system only distributes addresses to distinguish cable TV and broadband services according to user's option 60, can not satisfy and carry out the at first demand of broadband new business, therefore in the present invention, original DHCP system is transformed, can distribute the address for the user according to option 82 and option 60 information, allocation flow is specifically enumerated as follows as shown in Figure 2:
1. the user sends DHCP request, and the DHCP system extracts option 60 and option 82 fields in this request, and with the DHCP system in option 60 and the limited broadband user MAC tabulation comparison of disposing;
2. when the option that disposes in option 60 information of extracting and the DHCP system 60 is consistent, represent that then the user by set-top box transmission interactive TV service request, then is user's dispenser top box address field;
3. when comprising option 82 information of extraction in the limited broadband user MAC tabulation of disposing in the DHCP system, represent that namely the user has opened limited broadband services, distribute limited broadband address field;
When dispose in the option 60 that extracts and option 82 information and the DHCP system all inconsistent the time, distribute other address fields of giving tacit consent to.
As a kind of expansion of the present invention, preferably can consider to carry out under the non-CMTS access way address distribution of limited broadband services, so that method provided by the invention has the scope of application more widely.Alleged herein non-CMTS access way namely refers to the FTTx access way, for example, and modes such as FTTH, FTTO, FTTB.Because the network architecture of non-CMTS access way is different with the framework of CMTS access way, information the unknown among the option 82, so the DHCP system carries out address assignment according to the router mac address that carries in the user profile, its flow process as shown in Figure 3:
The user sends the DHCP request, the DHCP system extracts the MAC information of option 60 and network access equipment, and with the DHCP system in the option 60 that disposes and limited broadband user MAC tabulation relatively, the network access equipment under the non-CMTS access way is route, gateway etc.;
When comprising the route MAC information of extraction in the limited broadband user MAC tabulation of disposing in the DHCP system, distribute limited broadband address field;
When the option that disposes in option 60 information of extracting and the DHCP system 60 is consistent, dispenser top box address field;
When dispose in the option 60 that extracts and route MAC information and the DHCP system all inconsistent the time, distribute other address fields of giving tacit consent to.
Because under the CMTS access way, the ratio that sends the interactive TV business demand is higher, therefore under this mode, at first judges option 60 information, judges option82 information thereafter; And under non-CMTS access way, at first judge the network access equipment MAC information of (mainly referring to router); According to the judgement flow process of different access way design flexibilities, the calculation resources that makes address allocation procedure take is littler, and calculating process is accurately quick.
At the limited broadband user who distributes the address, the present invention also utilizes flow control system that limited broadband user is carried out flow control, and to utilize the DNS system be that limited broadband user realizes guiding push function, thereby realizes the authentication control to limited broadband user.
Wherein, flow control system is deployed between egress router and the fire compartment wall, as shown in Figure 4, needs the business of outlet bandwidth to do thick control at those, is used for the business without DNS is limited, as QQ software.Flow control system comprises the control operation that limited broadband user carries out: set up limited white list, the business that allows to pass through is added in the limited white list, for example browser related protocol, QQ software related service and agreement etc.; When the address that the user is assigned to is limited broadband services address field, to control according to limited white list, the business that only allows to enter limited white list is passed through, and all the other are professional, and no thoroughfare.
The realization of guiding push function mainly is based on DNS and realizes that the DNS system can control user's internet behavior details.When the user visited the content of lack of competence, system can force to push the guiding door, as the publicity of Operator Specific Service, can guide user's use on the other hand on the one hand, reduces the problem that the user in use occurs.
Guide the groundwork flow process of push function as shown in Figure 5, detailed process is as follows:
The dns resolution system receives user's request;
In the F5 of DNS system equipment (load-balancing device), be provided with matching strategy in advance, at first according to user's type, user's request is sent on the corresponding dns resolution server: if the user is common broadband user, then user's request is sent on the normal resolution server, realize user's normal parsing; When judging that address that the user is assigned to is limited broadband services address field, show that then the user is the user of limited broadband services, send to user's request on the limited broadband services resolution server this moment, realizes user's parsing.
Secondly, on limited broadband services dns resolution server, the access rights according to the user are guided the user:
If user's visit is open service, then normal parsing of limited broadband services resolution server realization, returning to the user after the normal parsing of the request of user's visit;
If the user visits the business of non-opening, then user's request is forwarded to the redirect machine, by the visit realization redirect of redirect machine process user.After the request of redirect machine process user, it is jumped to the portal page of limited broadband services, integrated corresponding operation system link realizes user's redirect guiding on door.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned execution mode, also comprises the technical scheme of being made up of above technical characterictic combination in any.
