Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, the embodiment of the invention is described in further details below in conjunction with accompanying drawing.At this, illustrative examples of the present invention and explanation thereof are used to explain the present invention, but not as a limitation of the invention.
As shown in Figure 1, in the embodiment of the invention, the handling process of network TV IPTV multicast service fault demarcation method can comprise:
Can learn that by flow process shown in Figure 1 in the embodiment of the invention, the emulation multicast source devices produces the emulation multicast data flow, and, the emulation multicast data flow that produces be consigned to the user as testing channel by the node in the end-to-end E2E forward-path of IPTV multicast service; The subscriber computer top box is set up the binding mapping relations between the multicast source address of each testing channel and corresponding emulation multicast data flow, and according to described binding mapping relations, receives the emulation multicast data flow of each testing channel correspondence; Thereby can rapidly and accurately IPTV multicast service fault be delimited based on end user's actual experience, not only can cover the end user, also can judge the quality problems that exist in the multicast network, fault demarcation ability is stronger; And the embodiment of the invention need not the subscriber computer top box and carries out fault-finding support on software and/or the hardware, can strengthen existing O﹠M means, and it is lower to dispose the cost of implementing.
For instance, can be in IPTV multicast service E2E forward-path, select some faults that are in to divide the node on duty border (for example on normal conditions, the quantity of selected node≤3).The emulation multicast source devices is paid the emulation multicast data flow that produces by these nodes to the user, the user can receive the emulation multicast data flow in the mode of watching testing channel.
For instance, the emulation multicast source devices is by the node in the end-to-end E2E forward-path of IPTV multicast service, can have multiple as the embodiment that testing channel consigns to the user emulation multicast data flow that produces, for example, emulation multicast source devices can be built in the node in the IPTV multicast service E2E forward-path.When the emulation multicast source devices is built in node in the IPTV multicast service E2E forward-path, the emulation multicast source devices produces the emulation multicast data flow, be the node generation emulation multicast data flow in the IPTV multicast service E2E forward-path, the emulation multicast data flow that produces sent to the user by the node in the IPTV multicast service E2E forward-path.
And for example, emulation multicast source devices can other be hung on the node in the IPTV multicast service E2E forward-path.When being hung on the node in the IPTV multicast service E2E forward-path by the emulation multicast source devices, the emulation multicast source devices is transmitted to the user with the node of emulation multicast data flow in IPTV multicast service E2E forward-path that produces after producing the emulation multicast data flow.
If in probe, realize aforementioned other extension mode, can strengthen the value of the barrier ability of declaring, lifting solution; If realize aforesaid built-in mode in the node in IPTV multicast service E2E forward-path, can reduce the deployment of probe, reduce the IPTV O﹠M cost.
Fig. 2 has illustrated built-in emulation multicast source devices of node and the other instantiation of hanging these two kinds of execution modes of emulation multicast source devices in IPTV multicast service E2E forward-path for the emulation multicast source devices consigns to user's concrete enforcement schematic diagram with the emulation multicast data flow as testing channel by the node in the IPTV multicast service E2E forward-path among Fig. 2.As shown in Figure 2, the BTV channel is from BTV channel program source, and forward-path A, node i, forward-path B, node j, forward-path C, node k, forward-path D in IPTV multicast service E2E forward-path are sent to set-top box.For instance, wherein forward-path A, B, C, each section of D can have the node of other not built-in or other extension emulation multicast source devices; Under other extension mode, testing channel L broadcasts group source device i through node i, forward-path B, node j, forward-path C, node k, forward-path D from emulation, is sent to set-top box; Testing channel M through node j, forward-path C, node k, forward-path D, is sent to set-top box from emulation multicast source devices j; Testing channel N through node k, forward-path D, is sent to set-top box from emulation multicast source devices k.
For instance, the emulation multicast source devices of built-in mode can realize in data communications equipment or access device that the emulation multicast source devices of other extension mode can realize in probe; That is, can be in data communications equipment in the IPTV multicast service E2E forward-path or the built-in emulation multicast source devices of access device; Perhaps, can the emulation multicast source devices be arranged in the probe at the node deployment probe in the IPTV multicast service E2E forward-path.
Fig. 3 is the schematic diagram of a kind of instantiation of emulation multicast source devices.As shown in Figure 3, emulation multicast source devices 300 can comprise memory cell 302, video segment wherein can prestore, memory cell 302 is connected with broadcast unit 306, broadcast unit 306 also links to each other with multicast transmission interface 308, the video segment that broadcast unit 306 can prestore memory cell 302 in the multicast mode sends (single channel or concurrent multichannel all can) from the node of multicast transmission interface 308 circulations to IPTV multicast service E2E forward-path, need not encoding and decoding.The video segment that memory cell 302 prestores can be SD or high definition, media formats can be MPEG-2, MPEG-4, H.264, form such as VC-1 so that be consistent with the professional used standard of the BTV of operator.During promptly concrete enforcement, when by the emulation multicast source devices, being hung on the node in the IPTV multicast service E2E forward-path, aforementioned emulation multicast source devices is transmitted to the user with the node of emulation multicast data flow in IPTV multicast service E2E forward-path that produces, can comprise: the emulation multicast source devices sends the emulation multicast data flow by the multicast transmission interface with the node circulation of multicast mode in IPTV multicast service E2E forward-path.In addition, in the emulation multicast source devices, but memory cell 302 connection management unit 304 also, administrative unit 304 also links to each other with order control interface 310 with broadcast unit 306 respectively.Emulation multicast source devices 300 can make 304 pairs of broadcast units of administrative unit 306 send the emulation multicast data flow and carry out Long-distance Control by order control interface 310 during enforcement.For example, can open or close testing channel by order control interface 310 Long-distance Control emulation multicast source devices, can be after opening by the multicast transmission interface 308 continuous loop play emulation multicast data flows of emulation multicast source devices.
Because the emulation multicast source devices consigns to user with the emulation multicast data flow as testing channel by the node in the IPTV multicast service E2E forward-path in the embodiment of the invention, can take certain network bandwidth and (suppose that 100 channels increase by 3 testing channels, then need to take about 3% bandwidth), therefore, when the network underloading, can use round-the-clock continuous broadcast emulation multicast data flow, make set-top box can both add testing channel at any time; When the shared bandwidth of needs restriction emulation multicast data flow, then can pass through the transmission of the provisional opening and closing emulation multicast data flow of order control interface Long-distance Control emulation multicast source devices.
During concrete enforcement, node in the end-to-end E2E forward-path of aforementioned IPTV multicast service can have polytype, and typical node can comprise: the boundary node of the Egress node of IPTV media server, metropolitan area network and Access Network, the multicast replication node that moves down (i.e. the multicast replication node of close user side) one of them or combination in any; Certainly, also can be other node in the end-to-end E2E forward-path of IPTV multicast service.Wherein, the exit point of IPTV media server for example can be core router or switch; The separation of metropolitan area network and Access Network for example can be BRAS (Broadband Remote Access Server, broadband access equipment) or SR (Service Router, business router); The multicast replication point that moves down for example can be convergence switch or DSLAM (Digital Subscriber Line AccessMultiplexer, Digital Subscriber Line Access Multiplexer) or OLT (optical line terminal, optical line terminal) equipment.
In order to allow testing channel be delivered to the user, during concrete enforcement, can be with EPG (the Electronic Program Guide of emulation multicast source devices and IPTV, Electronic Program Guide) subsystem combines, be similar to the mode that increases the local additional channel of IPTV, the multicast source address (be the multicast address of aforementioned emulation multicast source devices) of some testing channels with some emulation multicast data flows of correspondence bundled.
For instance, can set up binding mapping relations between the multicast source address of each testing channel and corresponding emulation multicast data flow; According to described binding mapping relations, provide the emulation multicast data flow of each testing channel correspondence to the user.Concrete, can set up binding mapping relations between the multicast source address of each testing channel and corresponding emulation multicast data flow at the subscriber computer top box; And then make user's set-top box receive the emulation multicast data flow of each testing channel correspondence according to described binding mapping relations.
Act one is for example shown in Figure 4, sets up binding mapping relations such as table 1 between each user and testing channel L, M, the N:
| The user | Testing channel L | Testing channel M | Testing channel N |
| The user 1 | Multicast address z | Multicast address y | Multicast address w |
| The user 2 | Multicast address z | Multicast address y | Multicast address v |
| The user 3 | Multicast address z | Multicast address x | Multicast address u |
| The user 4 | Multicast address z | Multicast address x | Multicast address t |
| ?…… | ?…… | ?…… | ?…… |
Table 1
When EPG asked channel information, EPG can send to set-top box with corresponding multicast source address with channel information according to the binding mapping relations to the user, thereby makes set-top box when needs acceptance test channel, can add correct multicast source address by set-top box.
, receive after the emulation multicast data flow of each testing channel correspondence according to described binding mapping relations at the subscriber computer top box, can watch the result of each testing channel, described IPTV multicast service is carried out fault delimit according to the user.For instance, according to the result that the user watches each testing channel, described IPTV multicast service is carried out the fault demarcation multiple concrete condition.Suppose that from live telecast BTV channel program source, the node in the IPTV multicast service E2E forward-path is followed successively by node 1～nodes X; Wherein X is the node sum; The testing channel of the emulation multicast data flow correspondence of paying by node 1～nodes X is testing channel 1～testing channel X, and X is the integer greater than 1, then:
If the user fails and watches live telecast BTV channel, can successfully watch testing channel 1, can determine that then BTV channel program source or BTV channel program source to the forward-path between the node 1 breaks down;
If the user fails and watches live telecast BTV channel and testing channel 1～testing channel Y-1, can successfully watch testing channel Y, can determine that then node Y-1 or node Y-1 break down to the forward-path between the node Y; Wherein, 1＜Y≤X; Certainly, in such cases, BTV channel program source or BTV channel program source to node between the node Y-1 or forward-path also may break down.For instance, delimit for realizing fault fast, can consider earlier that node Y-1 or node Y-1 break down to the forward-path between the node Y, if still can not watch live telecast BTW channel after group repaiies, consider it is that BTV channel program source or BTV channel program source to node or forward-path between the node Y-1 break down again.
Watch live telecast BTV channel and whole testing channel if the user fails, can determine that then nodes X or subscriber computer top box or nodes X to the forward-path between the subscriber computer top box breaks down.Certainly, in such cases, BTV channel program source or BTV channel program source to node between the nodes X or forward-path also may break down.For instance, delimit for realizing fault fast, can consider earlier that nodes X or subscriber computer top box or nodes X to the forward-path between the subscriber computer top box breaks down, if still can not watch live telecast BTW channel after group repaiies, consider it is that BTV channel program source or BTV channel program source to node between the nodes X or forward-path break down again.
Elaborate below in conjunction with the concrete enforcement of example to above-mentioned steps 103.
In this example,, adopt built-in emulation multicast source devices of node or the other execution mode of hanging the emulation multicast source devices in IPTV multicast service E2E forward-path by instantiation shown in Figure 2.When the user watches each BTV channel equal whens success, by watching testing channel successively, and according to watching that the result carries out fault and delimits.
In this example, the concrete enforcement that fault is delimited can be as shown in the table:
| The BTV channel | Testing channel L | Testing channel M | Testing channel N | Fault is delimited |
| Fail and watch | Can successfully watch | Breaking down in forward-path A or BTV channel program source, needs group to repair | ||
| Fail and watch | Fail and watch | Can successfully watch | Forward-path B or node i have fault, need group to repair, and transmit in this example more than the path A and wouldn't repair with considering to send | |
| Fail and watch | Fail and watch | Fail and watch | Can successfully watch | Forward-path C or node j have fault, need group to repair, and wouldn't repair with considering to send more than the forward-path B in this example |
| Fail and watch | Fail and watch | Fail and watch | Fail and watch | Forward-path D or node k or set-top box have fault, need group to repair, and wouldn't repair with considering to send more than the forward-path C in this example |
The typical application scenarios of the IPTV multicast service fault demarcation method of the foregoing description can comprise following processing procedure as shown in Figure 5:
Step 501, user beat hotline and give customer service one line, complain IPTV multicast service fault has taken place;
Step 502, customer service first-line staff inquire whether all BTV channels all can not normally be watched;
