Embodiment
To be illustrated technical scheme of the present invention below in conjunction with each preferred embodiment of the present invention.
Core concept of the present invention is:
1) encapsulation with IP of the multicast of PPPoE is realized;
2) the agreement special processing that the multicast of PPPoE is realized with the encapsulation of IP;
3) MAC Address according to the user identifies the PPPoE multicast user, thereby realizes the management to the PPPoE multicast user.
Concrete operations step of the present invention is as follows:
The first step: carry out the configuration of PPPoE multicast, the circuit that carries out pppoe session is bound, simultaneously IP port that does not have numbering of inner binding on this circuit;
Second step: insert the PPPoE multicast service:
1. the user reaches the standard grade by PPPoE, and in authentication phase, the PPP module obtains user's multicast authority information from the AAA client;
2.PPP module is told multicast protocol with user's multicast authority and MAC Address;
3. the user sends IGMP IGMP and joins request, and BAS Broadband Access Server BAS abandons the IGMP protocol data bag of PPPoE encapsulation, accepts the IGMP protocol data bag of IPoE encapsulation.
Handle the multicast protocol of PPPoE by the multicast protocol port on the described nothing numbering IP port of previous configuration.
4. multicast protocol extracts user's MAC address from IGMP message, according to MAC Address, searches user record and carries out the multicast authority checking.
5. set up the multicast member database, add multicast forward table
The 3rd step: transmitting multicast data
For the multicast packet that goes downwards to subscriber's main station, the access style different according to the user is converted to the IP multicast packet of corresponding encapsulated type
The 4th step: the user can IGMP leaves request or by leaving multicast group quietly, the user leaves multicast group two kinds of methods by sending:
1) can be by sending that IGMP leaves request or by leaving quietly;
2) PPPoE user offline
Below be the core content of the inventive method:
1, the encapsulation with IP of the multicast of PPPoE is realized:
The applicant has studied the multicast service client of a plurality of versions, and as Cisco IP/TV client software, Microsoft Streaming Media multicast services client etc., a common characteristic is found to have in the research back:
Behind user PPPoE access success, to the IP protocol data Bao Eryan on the subscriber's main station, two outlets are arranged, an outlet is the IP data envelope to be contained in the PPPoE frame be delivered to upstream equipment, promptly adopt the PPPoE encapsulation to transmit multicast packets, the another one outlet is that the IP packet directly is encapsulated in the mac frame, promptly adopts IPoE (IP on the Ethernet) encapsulation to transmit multicast packets.
When the user selects certain group broadcasting program, protocol stack will be a destination address with the multicast address of this program, send IGMP Report (Internet igmpinternet) bag.The IP bag is to adopt PPPoE encapsulation or IPoE encapsulation transmission hereto, and different client software performances is different.
Cisco IP/TV can select to adopt the PPPoE encapsulation to send earlier, and at the first-class pending data of the port of this PPPoE, if the data of receiving just begin broadcast program; If after waiting for 15～25 seconds, there are not data to arrive, it can send a Leave message earlier on the PPPoE port, again on the IPoE port, send IGMP Report message then, and beginning is in the arrival of the first-class pending data of port of IPoE, if the data of receiving just begin broadcast program; Otherwise the selection port that will repeat sends message and waits pending data.
Other client software is then different, and a port to IPoE that has sends message, and what have then sends protocol data simultaneously and wait for program data on two ports.
In a word, the scope in road as far as is known, client are are always received and dispatched protocol data and are waited for program data by adopting IPoE to encapsulate.
2, the agreement special processing that the multicast of PPPoE is realized with the encapsulation of IP:
When protocol processes, BAS Broadband Access Server is accepted the IGMP protocol data bag of IPoE encapsulation, abandons the IGMP protocol data bag of PPPoE encapsulation.
Because the circuit of PPPoE encapsulation generally is the authentication binding, for such circuit, there is not suitable driving interface to come to finish the transmitting-receiving of IPoE packet on the BAS (BAS Broadband Access Server) for it, therefore need specify an IP port for such circuit.
This IP port uses the IP address of not having numbering, and is bundled on the same circuit with PPPoE.When binding PPPoE circuit, generate such IP port.
This does not have the multicast protocol that the multicast protocol port of numbering on the IP port is finished PPPoE.
There are not the source IP address of the multicast packets that numbering IP port sends, the IP address that can from system, use an IP port arbitrarily from this.
3, the MAC Address according to the user identifies PPPoE user, realizes PPPoE multicast user's management:
Because the user is when carrying out multicast, the source IP address of employing is not the Microsoft Loopback Adapter IP address of pppoe session, but carries out the IP address on the real network interface card of pppoe session.Be that the user does not carry out multicast by the BAS IP address allocated,, at this moment can come identifying user, realize management the PPP multicast user according to user's MAC Address so can not come identifying user according to user's IP address.
Below be the implementation step of the specific embodiment of the inventive method:
The first step: carry out the configuration of PPPoE multicast
The circuit that carries out pppoe session is bound the encapsulated type of configuration circuit, the authentication protocol that PPP uses.
LAN of internal distribution drives port on this circuit, and binds an IP port that does not have numbering, and as shown in Figure 2, this does not have the protocol processes of multicast packets that multicast protocol port on the numbering IP port is finished the IP encapsulation of PPPoE.Originally the multicast protocol above the IP port of PPP binding abandons the multicast packets of PPP encapsulation.
Second step: insert the PPPoE multicast service
Be PPPoE multicast service access process as shown in Figure 1, described BAS Broadband Access Server comprises carrier module, multicast module and PPP module at least.
1. the user reaches the standard grade by PPPoE
In authentication phase, the PPP module obtains user's multicast authority information, and notes.Multicast authority information comprises: whether the user can flow by receiving group, the maximum multicast group number that the user can add, and whether the user can send multicast data flow, the multicast group that the user can add.
2. notice multicast protocol PPP user reaches the standard grade
PPP tells multicast protocol with user's multicast authority and MAC Address after ipcp negotiation is finished; Multicast protocol is created user record.
3. the user sends IGMP and joins request
The programme that the user pushes according to Portal Server perhaps directly according to multicast group address, sends IGMP and joins request.
BAS judges the multicast protocol bag according to protocol type, and BAS abandons the IGMP protocol data bag of PPPoE encapsulation, accepts the IGMP protocol data bag of IPoE encapsulation.
The multicast protocol bag is sent to the multicast protocol port on the nothing numbering IP port of previous configuration, finishes the multicast protocol of PPPoE.
4. multicast authentication
Multicast protocol extracts user's MAC address and multicast group address from IGMP message, according to MAC Address, search user record and carry out the multicast authority checking.Have in the multicast checking: whether the user can flow by receiving group, the maximum multicast group number that the user can add, and whether the user can send multicast data flow, the multicast group that the user can add.
5. set up the multicast member database
If the verification passes, then BAS reception user's IGMP joins request, and sets up the multicast member database, the group address of recording user, circuit information and MAC Address.Otherwise, abandon user's IGMP request message.
6. interpolation multicast forward table
The data forwarding module of multicast protocol notice BAS adds corresponding multicast forward table.The content of transmitting comprises: group address, user-side port number, vlan id.
The 3rd step: transmitting multicast data
When carrying out the PPPoE transmitting multicast data, carry out conversion to the encapsulation of PPPoE multicast packets.
The PPPoE access way that BAS can support comprises: PPPoE, PPPoEoV (PPPoE on the VLAN), PPPoEoA (PPPoE on the ATM).For the multicast packet that goes downwards to subscriber's main station, the access style different according to the user is converted to the IP multicast packet of corresponding encapsulated type.
The encapsulated type conversion of PPPoE multicast packet is as follows:
1) the PPPoE encapsulation is converted to the IPoE encapsulation;
2) PPPoEoV is encapsulated in and is converted to the IPoE encapsulation on each VLAN;
3) the PPPoEoA encapsulation is converted to IpoEoA (IPoE on the ATM) encapsulation.
The 4th step: the user leaves multicast group
The user leaves multicast group two kinds of methods:
1) can be by sending that IGMP leaves request or by leaving quietly;
Delete the multicast member database according to group address, and the deletion multicast forward table.
2) PPPoE user offline
PPP notifies multicast protocol, and user's MAC Address passed to multicast protocol, multicast protocol is deleted multicast user's record according to MAC Address, if do not had user record under the corresponding group address, then delete the multicast member database of this group, and the deletion multicast forward table.
By last, the present invention has realized the multicast procedures in PPPoE, and more than description is the description to embodiment, can not be interpreted as the restriction of scope that patent of the present invention is asked for protection, and scope of patent protection of the present invention should be as the criterion with claims.
