Embodiment one:

Serious, core router is occupied to understand existing multicast stream amount Managed Solution there are network bandwidth, and to handle load higher The problem of, the embodiment of the present invention provides a kind of access management method, in order to keep statement clearer, is also convenient for understanding, the present invention Embodiment, which is mainly stood, is described explanation in initial access equipment side, if necessary, while may be to other side (access-in managements Device, target access device) carry out corresponding description explanation！Access management method provided in an embodiment of the present invention specifically includes as follows Step refers to Fig. 2:

S201: the first request for requesting to be linked into target multicast group that current user equipment is sent is received.

It should be understood that before being initially accessed equipment and receiving first request that current user equipment is sent, usually Further include: establish the interface channel between the current user equipment.The interface channel established includes but is not limited to PPPOE logical Road, the channel IPoE.It specifically can be the current user equipment all broadband access equipment broadcast PPPOE agreements into multi-cast system Message is initially accessed equipment as the broadband access equipment for responding the protocol massages at first, will establish and the current user equipment Between the channel PPPOE, realize connection.First request subsequent so as to receive, which sends.

It should be noted that in the present embodiment, it is initially accessed what equipment was not limited to obtain based on response mechanism at first Broadband access equipment, can be with any other broadband access equipment, as long as establishing corresponding connection with the current user equipment Channel.Such as it can specify the specific broadband access equipment of multi-cast system as the initial wide access device.Each use Corresponding protocol massages are all directly sent to the specific broadband access equipment when establishing interface channel by family equipment, establish with The interface channel of the specific broadband access equipment.It can not need each broadband access equipment in multi-cast system and all respond user to set The protocol massages that preparation is sent, it is only necessary to which the specific broadband access equipment is corresponding, reduces the processing of other broadband access equipments Load.

Those skilled in the art could be aware that broadband access equipment includes but is not limited to BRAS, BNG (Broadband Network Gateway, wideband network gateway), BSG (Broadband Service Gateway, broadband services gateway), BAS (Broadband Access Server, BAS Broadband Access Server), OFLS (Openflow Logical Switch, open flows Logical switch), OFS (Openflow Switch, open flow switch) and the corresponding software emulation of above equipment.

Based on the interface channel established with the current user equipment, being initially accessed equipment can receive the current user equipment The first request for requesting to be linked into target multicast group sent.The information of target multicast group is carried in first request, The including but not limited to IP address of target multicast group.Be initially accessed equipment the active user can also set according to the first request The information such as standby IP address.

S202: according to the first request generating device reselection request, the equipment reselection request can characterize current use The information of the target multicast group of family device request access.

Equipment is initially accessed according to the first request generating device reselection request, and the equipment reselection request can characterize and deserve The information, such as the IP address of target multicast group of target multicast group etc. of preceding user equipment requests access.Equipment reselection request master If being carried out based on the interface channel being initially accessed between equipment and access-in management device, set specifically, being for example initially accessed When the standby interface channel established with access-in management device is the channel OpenFlow, it is initially accessed equipment and is encapsulated into the first request In the PACKET_IN message of OpenFlow agreement positioning, it is above sent to access-in management device.

S203: the equipment reselection request is sent to access-in management device.

It is initially accessed equipment and the equipment reselection request of generation is sent to access-in management device, the mode of transmission is not limited to Aforesaid way can use existing any request sending method, as long as equipment reselection request can be sent to access-in management dress It sets.

In some instances, the first request that can also directly the current user equipment be sent by being initially accessed equipment forwards Access-in management device is given, as long as it is user equipment for requesting the message of access target multicast group that access-in management device, which can identify, ?.The equipment reselection request that access management product is sent according to equipment is initially accessed is based on corresponding selection mechanism, selects phase The target access device answered provides service for the current user equipment.Specifically, target access device is established in control and this is current Interface channel between user equipment, and control the target access device and be linked into the specified target multicast of the current user equipment Group, target access device receive the content stream data (namely multicast message) of the target multicast group, and are sent to and deserve preceding user Equipment, to provide network digital TV service for corresponding user.

It should be noted that corresponding selection mechanism specifically includes: determining the user device quantity that target multicast group has been added (namely with group number of devices N), in N >=1, namely shows to be added to the target multicast group there is currently at least one user equipment, The first object access device of access management product selection at this time, can guarantee that the current user equipment accesses the first object and connects It is added after entering equipment, in system in the user equipment of the target multicast group, at least there are at least two user equipmenies is to pass through Same broadband access equipment is linked into the target multicast group.And in existing multicast stream amount Managed Solution, due to directly by just Beginning access device is linked into target multicast group and provides service for user equipment, may cause each user for accessing same multicast group Equipment be the case where access respectively by different broadband access equipments cause core router to need for it is corresponding each Broadband access equipment sends the corresponding multicast message of a multicast group.The access management method that this programme provides is initially accessed Equipment can't be directly connected in the specified target multicast group of current user equipment, but receive the first of user equipment After request, to access-in management device sending device reselection request, by equipment reselection request, according to the access feelings of target multicast group Condition selects corresponding target broadband access equipment, when the user device quantity for having accessed the target multicast group is more than or equal to 1, protects The first object broadband access equipment for demonstrate,proving selection can make at least two user equipmenies for accessing the target multicast group in system be Access is realized by same broadband access equipment, and each user equipment avoided for access same multicast group passes through respectively Different broadband access equipments realizes the case where access, therefore can effectively reduce core router for the target multicast group Multicast message number of copy times reduces the processing load of core router, and then also will be effective to the occupancy of line bandwidth resource Alleviate.

It in some instances, can also include as shown in Figure 3 after equipment reselection request is sent to access-in management device Step S304 and S305, it is specific as follows:

S301: the first request for requesting to be linked into target multicast group that current user equipment is sent is received.

S302: according to the first request generating device reselection request, the equipment reselection request can characterize current use The information of the target multicast group of family device request access.

S303: the equipment reselection request is sent to access-in management device.

Above-mentioned steps S301-S303 is identical as step S201-S203 described in Fig. 2, and details are not described herein.

S304: receiving the equipment transportation instruction that the access-in management device is sent based on the equipment reselection request, according to The equipment transportation instruction disconnects the connection with the current user equipment.

After equipment reselection request is sent to access-in management device, access-in management device can also be received and asked based on this It asks the equipment transportation of transmission to instruct, that is to say that access-in management device is the selected target access device of current user equipment at this time It is not same broadband access equipment with equipment is initially accessed.At this point, being instructed according to the equipment transportation, being initially accessed equipment can know It is not individually not the selected target access device of access-in management device, at this point, disconnecting between the current user equipment Connection, no longer provides service for the current user equipment, namely be not linked into specified target multicast group.

The identification information that target access device can be carried in equipment transportation instruction is initially accessed equipment according to the target Whether the identification information judgment of access device itself belongs to target access device, if it is not, then disconnecting and the current user equipment Connection, if so, can then be linked into target multicast group, with to the current user equipment provide the target multicast group it is corresponding in Hold information.

In some instances, after equipment gravity treatment instruction is sent to access-in management device, being initially accessed equipment can be with According to the response for whether receiving access-in management device in preset time period, Lai Jinhang respective handling.If within a preset period of time Do not receive the response of access-in management device, then showing itself not is the selected target access device of access-in management device, When preset time reaches, the connection with the current user equipment is disconnected.If receiving access-in management device within a preset period of time Response, then show itself to be exactly the selected target access device of access-in management device, be directly connected to the target group at this time Group is broadcast, to provide corresponding network TV content data flow to the current user equipment.

S305: receiving the first multicast incoming instruction that the access-in management device is sent based on the equipment reselection request, It is linked into the target multicast group according to the first multicast incoming instruction, to provide the target to the current user equipment The corresponding content information of multicast group.

After equipment gravity treatment instruction is sent to access-in management device, if receiving first group of access-in management device transmission When broadcasting group access request, illustrate that being initially accessed equipment is also the selected target access device of access-in management device, therefore access Instruction is linked into the target multicast group, to provide the target multicast group corresponding content letter to the current user equipment Breath.

Embodiment two:

The embodiment of the present invention is mainly stood in access-in management device side, and a kind of access management method is provided, and is mainly used for solving Existing multicast stream amount Managed Solution occupies serious, core router there are network bandwidth and handles the higher problem of load, this method Mainly include the steps that as shown in Figure 4:

S401: receiving and be initially accessed the equipment reselection request that equipment is sent, and the equipment reselection request can characterize currently The information of the target multicast group of user equipment requests access.

Access-in management device can with and the intractable equipment reselection request for being initially accessed equipment and sending, wherein equipment reselection request The information of the target multicast group of current user equipment request access can be characterized.Access management product can be according to the equipment gravity treatment Request requests the information, such as the IP address of target multicast group of target multicast group etc. of access to user equipment.

S402: determine that the same group equipment is to have connect in system with group number of devices N according to the information of the target multicast group Enter the user equipment of the target multicast group.

Access management product is determined according to the information of target multicast group with group number of devices N, it should be noted that same to main equipment Refer to the user equipment that the target multicast group is had access in multi-cast system.For example, the mesh of current user equipment request access Mark multicast group is multicast group A, and access-in management device currently has access to target multicast group A's according to equipment reselection request, determination All user device quantities, it is assumed that there are user equipment a and user equipment b the two user equipmenies have access to the target multicast group A, then user equipment a and user equipment b are then with group equipment, it is at this time 2 with group number of devices.

S403: being that the current user equipment determination meets condition from each broadband access equipment of system in N >=1 First object access device, after guaranteeing that the current user equipment accesses the first object access device, the system It is middle to access same broadband access equipment with group equipment there are at least two.

It determines and that is to say that there are at least one user equipmenies to have access to target multicast in N >=1 with group number of devices N Group, at this time access-in management device determine the condition that meets from each broadband access equipment in system for the current user equipment the One target access device.It should be noted that meeting condition includes: that current user equipment is linked into the first object access device Afterwards, same broadband access equipment is accessed with group equipment there are at least two in system.

In order to better understand, it is illustrated below with specific example:

Assuming that N=1, that is to say that the user device quantity for accessing the target multicast group in current system only has 1, it is assumed that use Family equipment m, the user equipment m broadband access equipment connected directly (is assumed to be broadband access by access-in management device at this time Equipment k) is used as first object access device.That is to say makes current user equipment and user equipment m all by same broadband access Equipment is linked into identical multicast group (target multicast group).To guaranteeing in N=1, current user equipment access described the One target access device (after broadband access equipment k), (that is to say current there are at least two with group equipment here in the system User equipment and user equipment m) access same broadband access equipment (broadband access equipment k).

Data service is provided for current user equipment and user equipment m simultaneously by this broadband access equipment k, specifically , broadband access equipment k passes through the core router of its upstream, is linked into target multicast group.At this point, core router only needs It to replicate a for the multicast message of the target multicast group and be sent to broadband access equipment k, core router and width Also only need to occupy the bandwidth of a multicast message with the line bandwidth resource between access device.Avoid existing multicast stream amount Managed Solution directly passes through initial access equipment and is linked into target multicast group, each user for the same multicast group of access that may cause Equipment is the case where access respectively by different broadband access equipments, for example, there is currently accessed target multicast group User equipment m, and the user equipment is to be linked into target multicast group by broadband access equipment k, can using existing scheme It can be linked into target multicast group by being initially accessed equipment (being assumed to be i), at this point, namely user equipment m is to pass through broadband access Equipment k is linked into target multicast group, and current user equipment is to be linked into target multicast group by being initially accessed equipment i. The two is to be linked into same multicast group by different broadband access equipments, at this point, core router will be directed to the target multicast The multicast message of group, needs to replicate two parts simultaneously, portion is sent to broadband access equipment k, and then sends out by broadband access equipment k User equipment m is given, another needs to be sent to broadband access equipment i, and then is sent to current use by broadband access equipment i Family equipment.It then will undoubtedly increase the processing load of core router, while also increasing the occupancy of line bandwidth resource.

If N > 1, show that the user equipment that target multicast group is had access in current system includes at least 2, at this point, There may be the following two kinds dispositions for access-in management device:

First is that having existed 2 or more if currently having access at least two user equipment of target multicast group User equipment is when being linked into same broadband access equipment, and at least two same group equipment accesses are same in guarantee system at this time One broadband access equipment, access-in management device can select any one broadband access equipment to connect as first object from system Enter equipment.It that is to say, whether the broadband access equipment number M that judgement has accessed target multicast group is less than with group number of devices N, if It is then to illustrate that at least there are 2 user equipmenies is linked into same broadband access equipment.It should be understood that access mesh The broadband access equipment number M of mark multicast group at most only has to be equal to that is to say a user without being likely larger than N with group number of devices N Equipment is generally impossible to be connected with two broadband access equipments simultaneously.

Further, it is assumed that currently having access to the user equipment of target multicast group includes user equipment 11 and user equipment 12 the two user equipmenies, if user equipment 11 and user equipment 12 are linked by same broadband access equipment 21 at this time Target multicast group, then can choose in system any one broadband access equipment as the first object access device； It can also will directly select the same broadband access equipment 21 that the user equipment 11 and user equipment 12 are connected and be used as the first mesh Access device is marked, at this point, core router will only need to replicate portion to the same width for the multicast message of target multicast group Band access device 21, reduces the processing load of core router to the full extent, and reduces to the full extent to bandwidth The occupancy of resource.

In some instances, it is assumed that currently having access to the user equipment of target multicast group includes user equipment 11, user Equipment 12 and user equipment 13 these three user equipmenies, and user equipment 11 and user equipment 12 are connect by same broadband Enter equipment 21 and is linked into target multicast group, and user equipment 13 is that the target multicast group is linked by broadband access equipment 22 , at least two same groups equipment (user equipment 11 and user equipment 12) access same broadband access in guarantee system at this time Equipment 21, therefore any one broadband access equipment (certainly including broadband access equipment 21 and 22) can be selected to make from system For first object broadband access equipment.

It is possible to further select any one broadband access equipment as first from broadband access equipment 21 and 22 Target broadband access equipment.At this point, can also further determine that the multicast group number that broadband access equipment 21 and 22 is respectively accessed, Select the smallest broadband access equipment of incoming multicast group number as first object access device.It should be understood that determining Broadband access equipment 21 and 22 has not necessarily only accessed target multicast group, it is also possible to other multicast groups are integrated into, at this point, The smallest broadband access equipment of incoming multicast group number is selected to access from broadband access equipment 21 and 22 as first object Equipment, such as the multicast group number that broadband access equipment 21 is accessed is 3, the multicast group number that broadband access equipment 22 is accessed is 1 (namely only accessing the target multicast group), then can choose broadband access equipment 22 is used as first object access device, with Realize load balancing.

If the multicast group number that broadband access equipment 21 and 22 is accessed is also identical, further basis can also respectively be carried User device quantity, come select the smallest broadband access equipment of carried user device quantity as first object access set It is standby.

In some instances, if user equipment 11, user equipment 12 and user equipment 13 are connect by same broadband When entering the case where equipment (being assumed to be broadband access equipment 23) is linked into target multicast group, at this time also in guarantee system at least Two are accessed same broadband access equipment with group equipment.Any one roomy access device (packet certainly is so selected from system Include broadband access equipment 23) as first object access device.It is possible to further directly by 23 conduct of broadband access equipment First object access device so that core router will only need to replicate for the multicast message of target multicast group it is a same to this One broadband access equipment 23 reduces the processing load of core router to the full extent, and reduction pair to the full extent The occupancy of bandwidth resources.

It is to connect there is no 2 user equipmenies second is that currently having access at least two user equipment of target multicast group When entering into same broadband access equipment namely a user equipment is correspondingly connected with unused broadband access equipment.

For example, being user equipment 11 and user equipment 12 respectively, respectively being connected with group equipment there is currently two Broadband access equipment is not same broadband access equipment, it is assumed that is linked into target multicast by broadband access equipment 24 and 25 respectively Group needs to select at this time one from broadband access equipment 24 and 25 as first object broadband access equipment, to guarantee to access At least two user equipmenies to target multicast group are carried out by same broadband access equipment.For example, selection broadband access Equipment 24 is used as first object access device, then then there is user equipment 11 and current user equipment is connect by same broadband Enter equipment 24 to be linked into target multicast group.Also the processing load of core router is effectively reduced.

Further, selected from broadband access equipment 24 and 25 one as first object broadband access equipment when, It equally can be according to the incoming multicast group number of broadband access equipment 24 and 25 or the user device quantity carried, by incoming multicast group Number or the smallest broadband access equipment of user device quantity carried are as first object broadband access equipment.

It in some instances, such as there are three is that user equipment 11, user equipment 12 and user set respectively with group equipment Standby 13, the broadband access equipment respectively connected is not same broadband access equipment, it is assumed that passes through broadband access equipment respectively 26,27,28 be linked into target multicast group, need to select from broadband access equipment 26,27,28 at this time one as first object Broadband access equipment, with guarantee be linked into target multicast group at least two user equipmenies be by same broadband access equipment into Capable.At this point, equally can choose any one broadband access equipment or the multicast accessed according to each broadband access equipment Group number, the user device quantity carried are selected, and details are not described herein.

It is connect in the multicast group number accessed according to broadband access equipment or the user device quantity carried selection first object During entering equipment, whether the multicast group number that can also judge that the broadband access equipment is currently accessed reaches given threshold, It specifically includes:

Such as it is currently accessed same group of equipment of target multicast group, it is assumed that including user equipment 14 and 15, user equipment 14 It is target multicast group to be linked by broadband access equipment 29, and user equipment 15 is linked by broadband access equipment 30 Target multicast group, if judging, the multicast group that broadband access equipment 29 and 30 is respectively accessed all is 10, has reached the group of setting A group number access threshold value is broadcast, can choose other roomy access devices at this time as first object broadband access equipment.

S404: notifying the first object access device to be linked into the target multicast group, to set to the active user It is standby to provide the target multicast group corresponding content information.

Notice first object is linked into target multicast group, corresponding interior to provide target multicast group to the current user equipment Hold information.First object access device may be initial access equipment, it is also possible to not be to be initially accessed equipment.It is connect in first object When entering equipment to be initially accessed equipment, the first multicast incoming instruction can be sent to the first object access device, it should with control First object access device is linked into target multicast group, to provide target multicast group corresponding content letter to current user equipment Breath.It is not to be initially accessed equipment in first object access device, the access of the second multicast can be sent to first object access device Instruction obtains the current user equipment information to control first object access device, then according to the current user equipment Information establishes the connection between the current user equipment, and accesses the target multicast group, to set to the active user It is standby to provide the target multicast group corresponding content information.

Meanwhile first object access device be not be initially accessed equipment, can also to be initially accessed equipment send setting Standby migration instruction disconnects the connection with the current user equipment with control initial access equipment.It in some instances, can also be with It should be initially accessed equipment without phase, when predetermined period reaches, automatic trigger is initially accessed equipment and disconnects and the current use The connection of family equipment.

In some instances, before being determined according to the information of target multicast group with group number of devices N, it is also necessary to determine current The multicast group accessed is not present in user equipment.If current user equipment has the multicast group accessed, and request at this time It accesses new target multicast group namely user and wishes that accessing two multicast groups namely user simultaneously wishes to watch two electricity simultaneously The programme content of tv channel, and the previous user equipment of mesh can only connect a broadband access equipment simultaneously, it is then directly logical at this time It crosses the broadband access equipment currently connected and is linked into target multicast group.
