Abstract
The invented method for authenticating the multicast request includes following steps: (1) the authentication for logging the user on. (2) The network device records the user's related information, combining with the operation attributes (whether the multicast is opened) to generate one recorder. (3) The user obtains the genetic networked service through network (4). The user send out the request package of applying for joining a multicast group. (5) With the request package being received, the network device picks up the user's relevant information. (6) Base on the user's information, the network device searches the recorders. If the user is a legal user of the multicast group, the authentication is passed. Otherwise, the user is refused admittance.
Description
The present invention relates to data communication field, relate in particular to the method that in the broadband access system multicast service is authenticated, the present invention provides a kind of method of knowing user's legal identity of debating as the precondition of the charging of value-added service in the broadband network.
At present, in data communication field, broadband technology has obtained application more and more widely.When a plurality of users apply for that simultaneously certain online service is (as video, audio service) time, corresponding server sends the datagram of same content will for each user, at this time, can identify the user that all have same requirements with a multicast address, server only need send datagram to this virtual multicast address, sends to corresponding multicast user automatically by the node on the network, and does not need all to send out a identical datagram for respectively each user.This process is called multicast, can save the bandwidth resources of network greatly.
Along with the continuous expansion of broadband application scope and the rapid increase of number of broadband customers, multicast has become a kind of important means that operator attracts the user.With regard to present circumstances, multicast just as a kind of Additional Services, is refused nobody under many circumstances, responds to every plea, and the user is not charged.Can foretell that along with enriching of multicast content, multicast service must be charged from now on, and the prerequisite of charge is will multicast to be authenticated earlier, on the basis of authentication, could carry out next step possible multiple charging way flexibly.
Because present multicast service opens for free, so, do not retrieve the various documents of relevant multicast authentication as yet.
The objective of the invention is provides a kind of method of authentication for the multicast service of generally carrying out at present, so that can charge according to authentication result team multicast service from now on.It can combine with multicast authentication with to access authentication of user simultaneously, makes operator more simple to user's management.Certainly, this combination to this method not necessarily.To achieve these goals, the present invention proposes a kind of method that multicast is authenticated, step is as follows:
Step 1, user's logging in network, whether network equipment decision allows the user to use Internet resources;
Step 2, if network allow this user to use Internet resources, network equipment recording user relevant information, and
Be associated with this user configured service attribute (whether opening), generate a record as multicast service;
If network allows this user to use Internet resources, then enter step 7;
Step 3, user obtain general business of networking by network;
Step 4, user send the request package that application adds certain multicast group;
Step 5, the network equipment receive this request package and extraction user related information wherein;
Step 6, the network equipment are searched record with this user profile, if show that this user is a legal multicast user, it are added multicast group, and authentication is passed through; Otherwise, enter step 7;
Step 7, refuse this user and add multicast group.
So just realized authentication to user multicast service.
The present invention proposes a kind of method that multicast service is authenticated, no matter which kind of access way the user adopts to realize authentication to multicast service.Its maximum characteristics are the authentication of multicast and access user's association attributes to be associated, make operator's leading subscriber very easily.Adopt this method to accomplish: (1) user enjoys business of networking but does not have the multicast service function; (2) user enjoys business of networking and has multicast service simultaneously; (3) user only enjoys the multicast service function.Make operator very flexible, and can be implemented on the basis of authentication the user is chargeed the opening of value-added service.
Below in conjunction with drawings and Examples the present invention is further described:
Fig. 1 is a kind of typical networking diagram of broadband access network;
Fig. 2 is the flow chart of the method for the invention;
Fig. 3 is the flow chart of the embodiment of the invention.
Read for convenience and understanding, below english abbreviation be explained as follows:
AAA authenticates, authorizes charging
IGMP inter-network igmpinternet
Application adds the request package of networking group in the IGMP JOIN inter-network igmpinternet
The PPP point to point protocol
Transmit PPP on the PPPoE Ethernet
Shown in Figure 1 is a kind of typical networking diagram that the present invention uses, and the authentication method to multicast service of the present invention is mainly used in the broadband access network, also can be applied on any one data network node with subscriber management function.
Present broadband access network mainly consists of the following components: local side apparatus, ustomer premises access equipment.Local side apparatus is connected by optical fiber or cable with ustomer premises access equipment, and access device (as computer) is linked on the ustomer premises access equipment by cable.In technical scheme of the present invention, local side apparatus and ustomer premises access equipment have all played corresponding effect.Local side apparatus is mainly realized the management to the user, as handling the calling of PPPOE, finishes authentication to the broadband user with aaa server, or by DHCP dynamic assignment IP address.Simultaneously local side apparatus and ustomer premises access equipment are realized multicast service to the user by the IP mode together, and ustomer premises access equipment also might be brought some unique informations of user up by certain mode, assists local side apparatus that user multicast service is authenticated.
Local side apparatus among Fig. 1 generally is the access device (as BAS Broadband Access Server) that has three layer functions, can discern user identity, all are inserted the user carry out the authentication and the charging of access network, equipment generally provides PPPOE termination function, DHCP distributing IP address, aaa protocol entity, IGMP protocol entity etc.; Ustomer premises access equipment generally is made up of Layer 2 switch, isolates must realize by office's side apparatus alternately between the user between the user.
In order to realize authentication to multicast service, local side apparatus by in the request package of extracting the user and asking to add multicast group some can the identifying user identity data (as user's MAC Address, the IP address, if can bring the port information of user side equipment up with certain form, also can be the port information of user side equipment), some attributes that need when itself and broadband user are surfed the Net are (as MAC Address, the IP address, if can bring the port information of user side equipment up with certain form, also can be the port information of user side equipment) bind the authentication that realizes the multicast user, judge that the request of which adding multicast is legal? which is illegal.
Fig. 2 is the flow chart of the method for the invention.In the method for the invention, when the user adopts different access way access networks, can carry out re-authentication to the user who proposes the multicast service requirement according to operator or service provider's requirement, and can take the charge mode different with common business of networking.
The present invention comes down to method a kind of and that the access way user combines for the method for multicast authentication.
Among Fig. 2, at first be an address allocation procedure and a verification process that the user is inserted.The address allocation procedure had here both comprised user's static configuration fixed ip address, had also comprised other all dynamic address allocation processes such as DHCP, PPPOE; Equally, the mode of authentication also can be various, as combine with aaa server, application layer authentication etc.;
After authentification of user passed through, access network had had user's relevant information, and had known user's legitimacy from database;
After the user asks to add the request package arrival of multicast group, just can carry out the authentication of multicast according to the user's information that is comprised in the request package.
Use method of the present invention, can also realize making the user only to enjoy the multicast service function, be that user's network equipment permission equipment when the initial log network inserts, but do not give this user open any business, only open multicast service after this user passes through multicast authentication, this moment, the user can only enjoy the multicast service function.
In Fig. 3 embodiment of the invention, user's access way is the access way based on PPPOE.
The present invention does not have special requirement to hardware, mainly says the step of embodiment of the invention realization here:
Automatically obtain an IP address by the Dynamic Host Configuration Protocol server on the access server when 1, the user starts shooting.Dynamic Host Configuration Protocol server gets up user's MAC Address and IP address binding simultaneously, and it is invalid that initial setting changes binding;
2, user's desire is used the Internet resources of broadband access network, must initiate PPPOE and call out, and user profile is delivered to the PPPOE processing entities of BAS Broadband Access Server by Ethernet switch;
3, the PPPOE processing entities of BAS Broadband Access Server and the RADIUSClient entity on the BAS Broadband Access Server carry out giving RADIUS Client entity with user profile alternately, and RADIUSClient and radius server are finished the authentication to the user together;
4, after authentication was passed through, BAS Broadband Access Server allowed the user to insert, and business such as online can be provided.The binding relationship of setting up in the MAC Address of the subscriber's main station that obtains when BAS Broadband Access Server is called out PPPOE simultaneously and the step 1 mates, and binding relationship is changed to effectively.Exist two IP addresses on the client computer this moment, and one is used for the PPPOE online by the PPPOE acquisition, and another is used for the access of IP mode.
5, the user sends the request package that application adds certain multicast group if the adding multicast services at first starts client multicast program.Request package is generally IGMP JOIN bag, with the form encapsulation of IP bag.
6, BAS Broadband Access Server recognizes IGMP JOIN bag, and whether its IP address of verification exist with the MAC Address binding relationship, if do not exist, then refuses; Otherwise local side adds multicast group with it, and subscriber's main station obtains multicast services by the packaged type of IPOE like this, and has realized the authentication of multicast services.
Understand method of the present invention for the ease of concrete, below just the user adopt the situation of PPPOE access way and IPOE access way to be described respectively respectively.
(1) (the PPPOE mode of saying has here comprised that all are with PPPOE calling login to the PPPOE mode
The mode of network)
(2)
The user calls out by after authentication and the logging in network by PPPOE, access network is noted user's relevant information (if can bring the port information of user side equipment up with certain form as user account number, SessionID, user's MAC Address, IP address, also can be the port information of user side equipment);
Whether the user has the multicast service function generally by network management configuration, and relevant with the user, can be relevant with user's account number, and user's MAC Address be correlated with, or relevant with the port information of user side equipment under the user;
When the user will add certain multicast group, should send the request package that application adds certain multicast group; Request package is generally IGMP JOIN bag, with the form encapsulation of IP bag.
Access network recognizes IGMP JOIN bag, extracts the data (can be IP address, MAC Address, if can bring the port information of ustomer premises access equipment up with certain form, also can be the port information of ustomer premises access equipment) of identifying user identity wherein
Access network compares the user profile that the data of identifying user identity and access network keep, and belongs to validated user, just confirms that its multicast service can open, and just with its adding multicast group, otherwise refuses.
So just realized the user is obtained the authentication of multicast service.
(3) (the IPOE mode of saying has here comprised packet fixed ip address, DHCP to the IPOE mode
Dynamic assignment IP address obtains IP address, logging in network mode)
When the user adopted fixed ip address, generally by the associating information of network management configuration with attribute of user (as whether having multicast service) and some identifying user identity, this was referred to as binding; (,, also can be the port information of user side equipment) if can the port information of user side equipment be brought up with certain form as user's MAC Address, IP address etc.
If the user dynamically obtains the IP address by the DHCP mode, after the IP address obtains, we bind the attribute of user (as whether having multicast service) and the information of some identifying user identity (as user's MAC Address, IP address etc., if can bring the port information of user side equipment up with certain form, also can be the port information of user side equipment), the configuration of this user property is also generally undertaken by webmaster;
When the user will add certain multicast group, can send the request package that application adds certain multicast group; Request package is generally IGMP JOIN bag, with the form encapsulation of IP bag;
Access network recognizes IGMP JOIN bag, extracts the data of identifying user identity wherein, (can be IP address, MAC Address, if can bring the port information of user side equipment up with certain form, also can be the port information of user side equipment)
Access network device compares the user profile that the data of identifying user identity and access network keep, and confirms that its multicast service can open, and just with its adding multicast group, otherwise refuses.
So just realized the user is obtained the authentication of multicast service.
Because at present popular access way is two kinds of PPPOE and IPOE, can not use other access waies but do not get rid of.When the user uses other modes to insert, the method that can adopt the present invention to propose equally, the associating information that relevant user information and user are added multicast group gets up to realize the authentication to the multicast user.
