Background technology
In recent years, along with IP (Internet Protocol, Internet Protocol) network popularizes on a large scale, and the develop rapidly of computer, network and image processing, transmission technology, IP video monitoring technology has also had development at full speed, and based on network IP supervisory control system progressively becomes the principal mode of supervisory control system.
Large scale deployment along with " global eyes "; the area that camera distributes is more and more wider; the territorial scope of being crossed over is increasing; video monitoring data is requisite in transmission course will use IP network; and this IP network is a bigger and complicated network; therefore; packet is difficult to guarantee by the transmission quality of this IP network; need to use relevant strategy to carry out the protection of transfer of data; make it in transmission course not packet loss or less packet loss, guarantee the normal stable operation of supervisory control system.
Use MPLS TE (Multi Protocol Label Switch TrafficEngineering in the prior art, multi-protocol label switching traffic engineering) technology to data the transmission in IP network protect, on the IP transmission network, set up the MPLS traffic engineering tunnel in advance, the subsequent video monitor data is transmitted by setting up good MPLS traffic engineering tunnel in advance, wherein, the subsequent video monitor data comprises live stream, is used to send to DC (Decoder, Video Decoder) equipment display monitoring image; The subsequent video monitor data also comprises storage flow, is used to send to the memory device, stores video monitoring data.As shown in Figure 1, because DC equipment can be under the jurisdiction of under the same router with memory device, also can be under the jurisdiction of under the different routers, so need to set up in advance one or two MPLS traffic engineering tunnels in the prior art.
For the previous case, in order to guarantee the normal transmission of video monitoring data in the MPLS traffic engineering tunnel, need that the network manager is in advance manual to set up enough big MPLS traffic engineering tunnel bandwidth, be greater than the storage flow and the live stream sum of high code check at least.In conjunction with shown in Figure 1, belonging to R2 with DC and memory device is example, and the video monitoring data that EC sends need send to DC or memory device through the MPLS traffic engineering tunnel between R1 and the R2.Under normal circumstances, the code check live stream that EC sends video monitoring data is 1M, is sent to R2 by R1; Exist under the unusual situation detecting certain zone, the code check that EC improves the code check live stream makes video data can show more distinct image on DC, simultaneously, EC can also send storage flow to memory device, makes the video data that EC obtains under the current abnormal conditions of memory device, stores; After unusual disappearance, EC reduces the code check of live stream, no longer sends video data to memory device simultaneously.But, because the bandwidth of the MPLS traffic engineering tunnel between router R1 and the router R2 is predefined fixed value, this fixed value is at least greater than the bandwidth sum of live stream under the abnormal conditions and storage flow, and can not reduce the code check of live stream or stop after memory device sends video data at EC, reduce the bandwidth of MPLS traffic engineering tunnel flexibly, thereby cause waste of network resources.
For latter event, as shown in Figure 1, code check live stream in the video monitoring data that EC sends sends to DC through the MPLS traffic engineering tunnel between R1 and the R2, storage flow in the video monitoring data that EC sends sends to memory device through the MPLS traffic engineering tunnel between R1 and the R3, EC equipment does not detect unusual the time, and the storage flow in this video monitoring data does not need to store on memory device.
In this case, after abnormal conditions disappear,, make that the MPLS traffic engineering tunnel between R1 and the R2 can't reduce bandwidth flexibly because the bandwidth of MPLS traffic engineering tunnel is predefined fixed value, MPLS traffic engineering tunnel between R1 and the R3 becomes the complete free time, causes waste of network resources.
