Abstract
The utility model discloses an implementation method for controllable multicasting service. Through the method, the user sends the request to the access control equipment for entering the multicasting service; the access control equipment delivers the request to the multicasting network side and judges the multicasting competence of the user. If the user is able to receive the multicasting program, the access control equipment will transfer the multicasting data flow from the multicasting network to the user, or such data will not be transferred to the user.

Background technology
On Internet, multimedia service such as Streaming Media, video conference and video request program etc. are becoming the important component part that information transmits.The mode of unicast of point-to-point transmission can not adapt to the professional transmission characteristic of this class, be that single-point sends the multiple spot reception, because server is necessary for the IP message copy that each recipient provides an identical content, also repeatedly transmit the message of identical content simultaneously on the network, taken ample resources.Though IP broadcast allows a main frame that an IP message is sent to the All hosts of same network, owing to not every main frame all needs these messages, thereby has wasted Internet resources.Multicast service arises at the historic moment in this case, and its appearance provides a main frame to send the method for message to specific a plurality of recipients.
Use multicast router to cooperate switch to realize multicast service together at present on the network.Network model as shown in Figure 1, the agreement of supporting on the multicast router mainly is the PIM-SD agreement.The agreement of supporting on the network switch mainly is multicast control protocol (IGMP).As Fig. 2, processing procedure was as follows when the user used group broadcasting program:
(1), the user sends the multicast service network switch that joins request;
(2), the network switch is transparent to the multicast network side with this request;
(3), multicast network sends to switch with multicast traffic stream;
(4), the network switch sends to the user with multicast traffic stream.
By above-mentioned flow process, the user just can receive the group broadcasting program data flow.Process was as follows when the user stopped using group broadcasting program:
(1), the user sends multicast service and leaves request;
(2), the network switch stops to send multicast packet to this user, simultaneously this request is transparent to multicast network one side.
(3) if the user side of the network switch has not had other users to use this multicast service, then multicast network just no longer sends multicast packet to switch.

Embodiment
Controllable multicast of the present invention is exactly on the network switch or Digital Subscriber Line Access Multiplexer functionally similar control appliances such as (DSLAM), utilizes related protocol to realize the control that the user inserts.As utilize multicast control protocol (be called for short IGMP), 802.1X agreement etc.Present embodiment is that the present invention will be described for example with the multicast control protocol.Networking diagram of the present invention is consulted shown in Figure 1.
In order to solve the problem of user management, set up local data base on control appliance, the authority to the user in this database is configured, and is receiving that the user joins request in the message, the authority of inquiring user and transmit according to user's control of authority message from database is consulted Fig. 3.
In multicast service, program is unique, and is corresponding one by one with multicast ip address, and user's multicast authority configuration is according to user's physical location or logical place configuration.
Carry out the authority configuration with physical location, each user distributes a unique device port, consults shown in the table one.
Carry out the authority configuration with logical place, each user distributes a unique user vlan ID, as shown in Table 2.

Consult 4, realize that with the network switch it is example that the multicast control protocol is intercepted (IPGM snooping) agreement, the flow process of controllable multicast is as follows:
(1) user sends the multicast service network switch that joins request;
(2) network switch is transparent to the multicast network side with this request, controls message is checked the user from the rights database of this locality authority according to the user who receives simultaneously;
(3) if the user has the authority of receiving group program, then the network switch is transmitted to the user with the multicast traffic stream that multicast network sends, otherwise multicast traffic stream is not sent to the transmission requesting users.
Consult 5, in order further to optimize professional control procedure, for the step among Fig. 4 (2), also can be according to whether the analysis result decision of user's rights of using is joined request to the multicast service that network side sends the user.Its process is as follows:
(1), the user sends multicast service to access control equipment and joins request;
(2), access control equipment is judged this user's multicast authority; If this user has the authority of receiving group program, then user's multicast service being joined request is sent to network side and continues step (3), otherwise abandons user's request message, finishes this time processing of request;
(3), access control equipment multicast traffic stream that multicast network is sent is transmitted to the transmission requesting users.
Consult Fig. 6, network switch controllable multicast module section comprises: user side control message receiver module, control message analysis module, IGMP message processing module (MPM) and multicast data message send control module.The IGMP message processing module (MPM) mainly is responsible for user's multicast authority analysis.
Consult Fig. 7, as follows to the processing procedure of message:
The receiver module monitoring of user side control message also receives all control messages that the user sends, and then these messages is sent to control message analysis module.
The user's message analysis module is classified to the control message according to the content of protocol domain in the control message, and the module that then various messages is sent to response is handled.If IGMP control message then sends to the IGMP message processing module (MPM); Otherwise carrying out other messages handles.
The IGMP message processing module (MPM) obtains multicast address and user's position from user's request message, whether the multicast authority according to position inquiring user from local data base of multicast address and user has authority to watch group broadcasting program to judge this user; If there is not authority, then do not carry out any operation; If authority is arranged, the multicast data message that then transmits control message sends control module.
Multicast data message sends the control mould and obtain user position information from the instruction of control messages, then according to instruction, activates this user's multicast message sending function.When receiving multicast packet, the network switch just sends to the user.
Consult shown in Figure 8ly, realize that with the network switch multicast control protocol agency (IGMP Proxy) agreement is an example, the flow process of controllable multicast is as follows:
(1) user sends the multicast service network switch that joins request.
(2) network switch is inquired about local database earlier, judges whether the user has the rights of using of multicast service.If authority is arranged then carry out step (3), if there are not rights of using, then the request message with the user abandons, and finishes this time request processing procedure.
(3), judge further whether the network switch sent identical group broadcasting program request to multicast network; If sent identical request, illustrate that group broadcasting program exists, just no longer send multicast request to multicast network; If do not send in the past, then send multicast and join request to multicast network.Multicast network is received and after the request group broadcasting program is sent to the network switch.
(4), the network switch sends to multicast packet the user of rights of using.
Wherein, the processing procedure of user's request message is consulted Fig. 6 and Fig. 7.
Process was same as the prior art when the user stopped using group broadcasting program among the present invention.
