Description
Technical field
The present invention relates to communication technical field, refer to a kind of method and system realizing multicast control at broadband access network especially.
Background technology
Multicast is a kind of data packets mode.By multicast mode, identical packet can be sent on the multiple destination hosts in same multicast group by source host simultaneously.Multicasting technology achieves efficient data transmission point-to-multipoint in IP network, because multicast effectively can be saved the network bandwidth, reduce offered load, be therefore all widely used in all many-sides such as Internet video, real time data transmission, multimedia conferencing, data copy, game and emulation.
IP multicast packets is containing two class basic agreements: multicast routing protocol and the internet group management protocol supported between router and main frame.Internet group management protocol comprises IGMP (the Internet Group Management Protocol based on IPv4, Internet Group Management Protocol) and based on the MLD (Multicast Listener Discovery, multicast listener discovery) of IPv6.A subscriber's main station uses internet group management protocol to notice the multicast group added desired by it.
In the multicast protocol of standard, recipient can add or leave arbitrary multicast group, does not consider user management problem.In order to realize the multicast service of management, operator must introduce multicast authority administrative mechanism in the network of its operation.The basic thought of multicast authority administrative mechanism configures a multicast authority table for each access user on multicast control appliance, when subscriber's main station adds the multicast group of specifying by IGMP or MLD request, multicast control appliance is according to the multicast authority table mandate of this user or refuse the request that this user adds multicast group, thus realizes the control to the multicast authority of user.
Described multicast control appliance is mainly used in user's access node of broadband access network, it is generally two-layer equipment, but can perception part three layer service, comprise Ethernet switch, integrated access equipment, DSLAM (Digital Subscriber Line Access Multiplexer, Digital Subscriber Line Access Multiplexer), PON (Passive Optical Network, EPON) local side apparatus OLT (Optical Line Terminal in network, optical line terminal) and ustomer premises access equipment ONU (Optical Network Unit, optical network unit) etc.
User opens and after have subscribed multicast service, operator is usually by NMS/EMS (Network Management System/Element Management System, network management system/Element management system), Telnet (Terminal Network, terminal network) or CLI (command line interface, Command Line Interface) mode static configuration user multicast power table on access control node, as shown in Figure 1.Wherein, the user ID of user's list item belonging to multicast authority table, MAC (Media Access Control can be comprised, medium access control) address, VLAN (Virtual Local Area Network, VLAN) number, PVC (Permanent Virtual Circuit, PVC) and line scan pickup coil side slogan (Circuit ID) etc.In multicast authority table, the corresponding multicast authority record of each record, comprises multicast identifier and corresponding authority composition.Wherein, authority is user to should the rights parameters of multicast group, represents whether this user can add this multicast group, and its value comprises and allows viewing, forbids viewing and preview.Multicast identifier comprises source specific multicast group (S, and Any-Source Multicast group (* G), G), (G) IP multicast address of this multicast group is represented, and (S) represents the designated multicast source IP address sending described multicast group data stream, (*) represents any multicast source address sending described multicast group data stream.In fig. 1, the channel that user A can access is (100.100.1.1,225.0.1.1), can the channel of preview be (100.100.2.1,226.0.1.1), the channel can not accessed is (3eff::1, ff02::0101) etc.The channel that user B can access is (*, 225.1.1.1), can the channel of preview be (*, 226.1.1.1), and the channel that can not access is (*, ff02::0101) etc.
Multicast authority control method comprises: when user to be added by multicast management protocol request or accesses certain multicast group, multicast control appliance is by resolving multicast management protocol message, obtain the multicast identifier that this user adds, in multicast authority table, search the multicast authority record that this multicast group is corresponding, obtain rights parameters and judge whether this user can add this multicast group.
As can be seen from the above-mentioned method controlled the multicast authority of user, it is the multicast authority table that each user's static configuration is very detailed in advance that existing method needs on multicast control appliance, and what multicast authority table stored is an accurate multicast authority record.No matter whether user online, the need of certain channel of access, as long as user opens and have subscribed multicast service, the multicast authority record of this user just prior configure on access device ready.Because the channel can selected for user become increasingly abundant, access control equipment will take huge memory space for all users configure a complete multicast authority table, there is the scaling concern of multicast authority number; And control appliance needs to spend the multicast authority of more time to user accurately to search coupling, thus substantially prolongs the switching time of multicast channel.Imagine the access node that has been accessed 1000 multicast users, will provide 500 alternative number of channels for each user, this has current demand.Prior art is adopted to be that all users configure a complete multicast authority table and need access node to store 1000*500=500,000 user multicast power record.The time supposing an access node sequential search multicast authority record is 2 microseconds, and matching the last item multicast authority record needs the cost time of 1 second.This not only adds the cost of access control equipment, also have impact on the experience performance of user to multicast service.

In described packet-broadcasting controlling system framework, access node is responsible for the control of user multicast power, the copying and forwarding of multicast message, and comprising: the configuration/deletion performing the multicast authority from multicast application system; The multicast receiving user adds/leaves request; From the multicast group management of user, obtain user ID and multicast identifier, request multicast application system issues corresponding multicast authority; From the multicast group management of user, obtain user ID and multicast identifier, search match user multicast authority table, according to rights parameters mandate or the multicast request refusing user.
In multicast control technology scheme of the present invention, unlike the prior art, access node is not by webmaster or Telnet or the CLI mode multicast authority table belonging to all users that static configuration one is complete in advance, but by the telescopic user multicast power table of ANCP mode Dynamic Maintenance one.In other words, described access node has how many users to add multicast request, just has the multicast permission information of how many users, and those do not send the join request user multicast power of message of multicast and there will not be in the middle of described multicast authority table.Described user multicast power table is dynamically changeable, when wideband network gateway detects the IP conversation (as dead in user terminal shutdown/power-off or deadlock, dialing application program deexcitation/extension, network connect abnormal disconnect etc.) of certain user, access node can receive the message of the multicast authority configuring request of this user of deletion that described wideband network gateway sends, described access node performs the multicast authority configuration order of deleting this user, deletes the multicast authority record of this user in described user multicast power table.Described access node is by the telescopic user multicast power table of Dynamic Maintenance one, memory space can be reduced to greatest extent, the restriction of the multicast authority number that effective solution multicast control appliance is supported, thus multicast network is expanded with being easy to more flexibly, reduce equipment manufacturing cost and operation cost.Meanwhile, also greatly reduce the time of searching the authority that certain specific multicast of coupling joins request at multicast authority table, improve the experience performance of user to multicast service.
The configuration flow of the multicast authority of access node described in the present invention is described below in detail.As shown in Figure 3, concrete steps are as follows:
Step 301, the TCP (Transmission Control Protocol, transmission control protocol) set up between access node and BNG based on ANCP connects, and both sides reach synchronous after consulting ability parameter.
It should be noted that, the mutual of all message packets in the present invention between access node with BNG is all communicated by ANCP.Described BNG can be the IP edge service access control equipments such as BRAS or SR.Meanwhile, BNG and policy control server are also set up and safeguard relevant connection, and interface protocol can be COPS (Common Open PolicyServices, Common open policy service), Diameter or RADIUS etc.Described policy control server both can be multicast service policy control server, also can be the policy unit of the multicast services such as aaa server, store the multi-cast business data that user contracts, these user data can be issued by multicast service management system and upgrade.
Step 302, user terminal is set up with BNG and is safeguarded IP session, obtains IP address, starts accesses network.
Described IP session can be IPOE (IP over Ethernet, Ethernet the transmits IP) session based on DHCP (DHCP), also can be that IP session fixed by special line.Described BNG needs the heartbeat detection of constantly user terminal being carried out to IP session, to safeguard the normal connection of IP session.
Step 303, when user terminal obtains behind IP address, when first time adds multicast request, described access node is resolved this multicast message that joins request, and obtains user ID and multicast identifier.
Step 304, access node searches asked multicast authority according to the user ID obtained and multicast identifier at user multicast power table, because the multicast authority of now this user is recorded as sky, this access node sends this user multicast power configuration request message according to obtained user ID and multicast identifier to BNG.
As an embodiment, the user ID in described multicast authority configuration request message comprises the information such as IP address, MAC Address and Circuit ID, is sent to wideband network gateway by ANCP.
Step 305, described BNG is relayed to policy control server this multicast authority configuration request message.
Step 306, described policy control server according to the user ID of carrying in multicast authority configuration request message to after user authentication, find the multicast permission information of respective user at user multicast database, issue all multicast authority configuration informations of this user to BNG.
Step 307, after described BNG receives the user multicast power configuration information that policy control server issues, builds user multicast power configuration response message message, gives described access node by ANCP loopback.
Step 308, described access node configures all multicast authority records of this user, reports execution result simultaneously to described BNG after receiving user multicast power configuration response message in user multicast power table.
Step 309, BNG to described policy control Server Relay from access node multicast authority configuration execution result.
So far, user multicast power configuration terminates substantially.In order to upgrade user multicast power table in time, empty useless information, can also continue to perform following steps:
Step 310, when described BNG monitors the IP conversation of certain user terminal, IP conversation may shut down because of user terminal/and dead, the network of power-off or deadlock, dialing application program deexcitation/extension connects the reasons such as abnormal disconnections and causes, and BNG sends the configuration request message of all multicast authorities of this user of deletion immediately to described access node.
Step 310, described access node deletes all multicast authority records of relative users after receiving the configuration request message of all multicast authorities of this user of deletion that BNG sends in user multicast power table.
Step 311, described access node reports execution result to described BNG.
Step 312, this deletion configuration result message of BNG relaying is to described policy control server.
The basic procedure that in the present invention, access node multicast controls is described below, as shown in Figure 4.Step is as follows:
Step 401-402, when the multicast that described access node receives user joins request, resolves this multicast message that joins request, obtains user ID and multicast identifier.
Step 403, access node searches asked multicast authority according to the user ID obtained and multicast identifier at user multicast power table, may there is following steps 404,407 two kind of situation:
If the multicast authority of this user of step 404. is recorded as sky, this access node sends this user multicast power configuration request message according to obtained user ID and multicast identifier to BNG, also may there are BNG carries out the following steps 405,406 of certification two kinds of situations to user multicast request:
Step 405, the multicast authority configuration request message certification of described BNG to user is passed through.When described access node receives the Multicast configuration response message from described BNG, all multicast authorities of configure user;
Step 406, described BNG refuses the multicast authority configuration request message certification of user.When described access node receives the Multicast configuration refuse information from described BNG, abandon the multicast request message of user, and stop follow-up process.
Step 407, if the multicast authority record that there is this user, obtains the rights parameters of corresponding multicast request from multicast authority table.
Described access node does following process according to the rights parameters of corresponding multicast request may comprise following three kinds of situations:
Step 408, if rights parameters=mandate allows, creates multicast forward table to user access port, completes multicast message and copy and forward;
Step 409, if rights parameters=mandate preview, creates multicast forward table to user access port, and enables preview number counter and preview duration timer respectively, complete multicast message and copy and forward;
Step 410, if rights parameters=mandate is forbidden, abandons the multicast request message of user, is left intact to user access port.
As the conclusion to detailed description, should notice that those skilled in the art will be apparent from can make many changes and amendment to preferred embodiment, and does not depart from principle of the present invention in fact.
