As shown in table 1, multicast source table 120 expression information about multicast source.All appear in the multicast source table 120 multicast sources that occur and have higher priority than other common multicast source, and they generally are to be provided and to public service by important content provider.Wherein, multicast address is used to represent the multicast ip address of this multicast group; Multicast source place VLAN is used to represent this multicast source place VLAN; Multicast bandwidth is used to the bandwidth of representing that this multicast data flow need take, can comprise maximum bandwidth and average bandwidth; The multicast source mask is used to represent that the user adds the needed authority of this multicast group, and can be understood as this multicast source is certain channel of which content supplier, is similar to as CCTV-1, CCTV-2 etc.Above-mentioned service parameter towards masses for NSP, all is known, so the multicast source table 120 that comprises these parameters can be set in the memory 12 that inserts local side apparatus 10 in advance.
Every multicast source of not listing multicast source table 120 in all is called the common multicast source.For user and Access Network local side apparatus, some parameters of these multicast sources are not also known.Therefore, unified common multicast stream to the common multicast source defines in common multicast parameter list 123.Wherein, multicast bandwidth is used to the bandwidth of representing that each common multicast stream need take, can comprise maximum bandwidth and average bandwidth, because the bandwidth that each common multicast stream actual needs takies and inconsistent, so when choosing this parameter, can come approximate representation with multicast data flow bandwidth commonly used; The multicast source mask is used to represent that the user adds the needed authority of common multicast group, also can be understood as a special channel.
Because the bandwidth of each user or the network port is different, it is to tenability of multicast and inequality, therefore must insert according to the multicast that each user or the network port are controlled this port to the tenability of multicast.In order respectively the described user or the network port to be controlled, to the tenability of multicast, in port multicast capability list 121, it is defined according to described user or the network port.Wherein, port numbers is used to represent the sign of a user or the network port; Maximum multicast number is used to represent that this user or the network port can support the number of maximum multicast data flow simultaneously; Maximum multicast bandwidth is used to represent that this user or the network port can allow to be used for the maximum bandwidth of multicast data flow; The multicast mask is used to represent the authority of this user or the network port, promptly can receive which channel of which content supplier, usually, the multicast authority of the network port should guarantee to insert any multicast, and the multicast authority of user port only guarantees that the user can insert the multicast that some ICP provides, and multicast source mask and the multicast source mask in common multicast parameter list 123 of the multicast mask in the port multicast capability list 121 in multicast source table 120 is used for judging whether the user has the authority that adds certain multicast group.
Tenability to 10 pairs of multicasts of Access Network local side apparatus in system multicast capability list 122 defines.Wherein, the number of the maximum multicast data flow that maximum multicast number is used to represent that Access Network local side apparatus 10 can be supported simultaneously, so that avoid inserting not manageability of too much multicast data flow, and the bandwidth of bandwidth that maximum multicast number is also supported with Access Network local side apparatus 10 in the reality and multicast data flow itself is relevant, and maximum multicast number comprises the number of listing the multicast data flow in the multicast source table 120 in and is contained in the number of the common multicast stream in the common multicast parameter list 123; The maximum number of the common multicast stream that maximum common multicast number is used to represent that Access Network local side apparatus 10 can be supported simultaneously, can do not taken fully so that guarantee the multicast-capable of Access Network local side apparatus 10, can provide service to the user to guarantee the multicast data flow that is contained in multicast source table 120 by common multicast stream.
Fig. 3 is the flow chart of the multicast access control method of a preferred embodiment of the present invention.The controller 11 of Access Network local side apparatus 10 inserts multicast according to handling process as shown in Figure 3 and controls.
At first, in step 301, the controller 11 of Access Network local side apparatus 10 receives the IGMP JOIN message that is used to ask to add certain multicast that comes from user port, enters step 302 subsequently.In step 302, the controller 11 inquiry port multicast capability lists 121 of Access Network local side apparatus 10 judge whether the maximum multicast number of this user port support is zero.If judged result is a "Yes", then execution in step 313, finish this operation; Otherwise, execution in step 303.
In step 303, the controller 11 inquiry multicast source tables 120 of Access Network local side apparatus 10 are determined this multicast source type, also promptly judge according to multicast address whether this multicast source is contained in multicast source table 120.If judged result is a "Yes", illustrate that this multicast source is important multicast source, then execution in step 304, otherwise, illustrate that this multicast source is the common multicast source, then execution in step 305.In step 304, the judgement of step after relevant parameter is finished in the parameter in the Access Network local side control appliance 10 use multicast source tables 120 and other table; The judgement of step after relevant parameter is finished in parameter in the controller 11 use common multicast parameter lists 113 of step 305 Access Network local side apparatus 10 and other table.
Then, in step 306, multicast mask in the controller 11 inquiry port multicast capability lists 121 of Access Network local side apparatus 10 and the multicast source mask in multicast source table 120 or the common multicast parameter list 123 judge according to these two parameters whether this user port has the authority that adds this multicast.If judged result is a "No", then execution in step 313, finish this operation; Otherwise, execution in step 307.
In step 307, the controller 11 of Access Network local side apparatus 10 judges whether this user port has had this multicast member.If judged result is a "Yes", illustrate that this group portion stream has been distributed to this user port, then execution in step 313, finish this operation; Otherwise, execution in step 308.
In step 308, the maximum multicast number and the maximum multicast bandwidth of Access Network local side control appliance 10 inquiry port multicast capability lists 121 judge whether this user port supports the ability of this multicast data flow in addition, and also promptly whether this user port also has enough resources.If judged result is a "No", then execution in step 313, finish this operation; Otherwise, execution in step 309.
In step 309, the controller 11 of Access Network local side apparatus 10 judges that whether also having other user in its all user port is the member of this multicast group.If judged result is a "Yes", illustrate that this multicast data flow has been distributed to this Access Network local side apparatus and therefore needn't have inserted again, then execution in step 313, finish this operation; Otherwise, execution in step 310.
In step 310, maximum multicast number in the controller 11 inquiry system multicast-capable tables 122 of Access Network local side apparatus 10, maximum common multicast number (multicast that inserts when request for common multicast time use this parameter) and maximum multicast bandwidth, judge whether its network port has enough abilities to support this multicast data flow, judge promptly also whether system has enough resources.If judged result is a "No", then execution in step 313, finish this operation; Otherwise, execution in step 311.
In step 311, Access Network local side apparatus 10 sends IGMP JOIN message to router one 2, and report is to the access request of this multicast.Simultaneously,, promptly be contained in the multicast source table 120, then use the multicast source place VLAN in the multicast source table 120, to realize the multicast of travelling across VLAN if this multicast source is important multicast source; If multicast source is the common multicast source, promptly be contained in the common multicast parameter list 123, then use from the VLAN in user's ethernet frame (if user's ethernet frame supported vlans is not just used the default vlan of user port), to realize multicast in the normal VLAN.At this moment, router one 2 is understood the member of Access Network local side apparatus 10 as this multicast group, and multicast data flow is distributed to get off, and employed VLAN receives that with router one 30 VLAN of IGMP JOIN message is consistent.
In step 312, Access Network local side apparatus 10 adds this multicast group to user port, and multicast data flow is distributed to this port.When multicast data flow when user port U1 and/or U2 flow out Access Network local side apparatus 10, if the ethernet frame that apparatus for media playing 151 and/or 152 sends supported vlans is not then peeled off former VLAN; Perhaps, if the ethernet frame supported vlans that apparatus for media playing 151 or 152 sends then changes user's VLAN into.
At last, in step 313, finish this operation.
More than embodiments of the invention are described.According to present embodiment, said system is meant the Access Network that uses ether Ethernet technology, and Access Network local side apparatus 10 is IP-DSLAM, and is based on existing IGMP and realizes message control.But the present invention is not limited to specific system, equipment and concrete agreement, and those skilled in the art can make various distortion or modification within the scope of the appended claims in this area.
