Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The words involved in the scheme are explained as follows:
video streaming: the technology and process are that after a series of videos are compressed, the data are sent by network segments, and video and audio are transmitted on the network in real time for viewing.
Frame: the single image frame of the minimum unit in the motion picture is equivalent to each frame of the shot on the motion picture film.
Code rate: the video streaming encoding format brings the sharpness of video data transmitted per unit time.
The monitoring center: by adopting the encryption method of the single-key cryptosystem, the same key can be used for encrypting and decrypting information at the same time.
Cascading: in the financial industry scene, an organization presents upper and lower video monitoring centers, wherein the upper monitoring center needs to call and read video streams from the lower monitoring center due to management service.
The key parts are: in the financial industry, a certain place is managed as a concept by taking a key part in a system as a concept under the requirement of security management.
The priority of the flow is as follows: the service attribute of the video stream itself, and the video streams with different priorities need to be effectively managed according to the priority.
Referring to fig. 1, a schematic diagram of a business process of different monitoring centers for retrieving video streams is shown:
1. the subordinate monitoring center accesses the video stream, the flow direction of the video stream is a key position- > the subordinate monitoring center through a path, and the flow is limited by the exit limit of the key position, the entrance limit of the subordinate monitoring center and the exit limit of the subordinate monitoring center;
2. the superior monitoring center retrieves the video stream, the flow direction of the video stream is the key position- > the subordinate monitoring center- > the superior monitoring center through the path, and the flow is limited by the exit limit of the key position, the entrance limit of the subordinate monitoring center, the exit limit of the subordinate monitoring center, the entrance limit of the superior monitoring center and the exit limit of the superior monitoring center.
Referring to fig. 2, a main flowchart of a video stream restriction method according to an embodiment of the present invention is shown, including the following steps:
s201: receiving an open flow request of a flow calling party to a target video flow, and acquiring a flow direction passing path of the target video flow according to main information of the target video flow; the flow direction passing path comprises a key part and a monitoring center;
s202: acquiring current first open flow information of key positions, and processing the first open flow information based on priority sequencing and current limiting conditions of the key positions so as to transmit the target video stream to a monitoring center;
s203: and acquiring current second open flow information of the monitoring center, and processing the second open flow information based on priority sequencing and the current limiting condition of the monitoring center so as to transmit the target video stream to the stream caller.
In the above embodiment, for step S101, the present solution is applicable to a scene that needs to monitor a video stream, such as a bank, a telecom/mobile/unicom, etc. that has a large number of similar organizations all over the country, where the video stream is a video stream in a monitoring system, including but not limited to a video captured by a monitoring device. And the scheme does not relate to the storage of the content of the video stream, and only relates to the storage of the state of each video stream in the stream control component.
Before each streaming, the system transmits the main information of each video stream to the current limiting service component, such as key position information, lower level monitoring center information, upper level monitoring center information, video stream priority and code rate.
The flow-restricting service assembly includes a plurality of flow control assemblies, with different flow control assemblies being disposed on different stage mechanisms. The current limiting service component itself holds the following core information:
1. all video stream information currently in an open stream state;
2. the total flow size and the open flow information (arranged from small to large according to the priority) of all the current key points. For example, although the video streams for routine inspection and the video streams for emergency alarm (such as fire and robbery) are both video streams, the video streams have different service attributes and therefore different priorities, and when the traffic is insufficient or reaches the upper limit, the video stream with the lower priority is preferentially closed.
3. The sizes of the open-flow inlet and outlet flows of all the current monitoring centers (the flows are arranged from small to large according to the priority).
When the stream caller initiates an open stream request for the target video stream, the open stream request enters the current limiting service component. The flow-limiting service component firstly checks a flow direction passing path of a target video stream according to main information of the target video stream, wherein the flow direction passing path comprises a flow control component passing a key part, an inlet flow control component of a lower monitoring center, an outlet flow control component of the lower monitoring center, an inlet flow control component of a higher monitoring center (under the condition of cascade), and an outlet flow control component of the higher monitoring center (under the condition of cascade).
For step S102, the key portion flow control component calculates the sum of the existing video streams at the current key portion to obtain the current open stream flow, and obtains the first flow demand total by combining the flow with the target video stream. And if the total quantity of the first flow demand exceeds the upper opening flow limit of the flow control assembly of the key position, screening the video stream with the lowest priority level from the existing video streams to be used as the video stream to be closed.
Embodiment one, see fig. 3 for a description of:
s301: calculating a difference value between the total quantity of the first flow demand and the open flow upper limit, and screening out the video stream with the lowest priority from the first open flow information;
s302: judging whether the flow demand of the video stream is greater than or equal to the difference value, if so, closing the video stream;
s303: and if the judgment result is negative, accumulating the plurality of video streams according to the sequence of the priority levels from low to high until the accumulated flow demand is greater than or equal to the difference value, and closing the accumulated plurality of video streams.
Referring to fig. 4 (a), 3 paths of flow are opened at the key point a, which are 4M, 1M and 2M, respectively, and the bandwidth is 7M/S through accumulation. The target video stream is 8M, and the sum of the target video stream and the target video stream is 15M. However, the upper limit of the open stream of the important part a is 12M, if the 8M stream needs to be opened, part of the existing video stream needs to be closed, and 1 path of 4M video stream is closed according to priority, as shown in fig. 4 (b). In some cases, it may be necessary to close multiple video streams, for example, when the newly opened video stream is greater than 9M and less than or equal to 10M, such as 10M and 9.5M, 1 way of 4M video stream and 2 ways of 1M video stream need to be closed. If the newly opened video stream is larger than 10M and smaller than 12M, all the currently opened video streams need to be closed.
In this embodiment, in order to open a target video stream, only a video stream having the lowest priority is selected from the open information existing in the important part, and the closing process is performed.
Example two, see fig. 5 for a schematic representation:
s501: calculating a difference value between the total quantity of the first flow demand and the open flow upper limit, and screening out the video stream with the lowest priority from the first open flow information and the target video stream;
s502: judging whether the video stream contains the target video stream, if so, ending the operation flow of the target video stream, otherwise, continuing the subsequent operation;
s503: judging whether the flow demand of the video stream is greater than or equal to the difference value, if so, closing the video stream;
s504: and if the judgment result is negative, accumulating the plurality of video streams according to the sequence of the priority levels from low to high until the accumulated flow demand is greater than or equal to the difference value, and closing the accumulated plurality of video streams.
In some cases, the priority of the target video stream is also lower, even lower than the video stream with the lowest priority in the existing streaming information of the important part, and at this time, the operation flow of the target video stream is ended. For example, the existing video stream of the important part is an emergency alarm (such as fire and robbery) video stream, the target video stream is a video stream of daily inspection, and the original video stream cannot be closed at this time.
Furthermore, the flow control component of the key part can also transmit the video stream to be closed to the stream caller in a list form, and inform the stream caller of the information of other video streams closed by the open flow target video stream. Or before/after closing the video stream, the information of the current video stream is informed to the stream caller in the form of a list.
In step S103, according to fig. 1, no matter the lower monitoring center is looking for the video stream or the upper monitoring center is looking for the video stream, the target video stream passes through the lower monitoring center, so that the flow control component at the inlet of the lower monitoring center is determined first.
Example, see fig. 6 for an illustration:
s601: acquiring current third open flow information of an inlet of a lower monitoring center, counting the total flow of current open flow according to the third open flow information, and combining the flow of the target video flow to obtain a second flow demand total amount;
s602: judging whether the total quantity of the second traffic demand is greater than the upper opening limit of an inlet of a subordinate monitoring center, and if not, not processing the third opening information;
s603: if yes, screening one or more video streams with the lowest priority from the third switching information and carrying out closing processing.
The flow control component of the same-point part calculates the sum of the existing video flows on the inlet of the current subordinate monitoring center to obtain the current opened flow, and obtains the total quantity of the second flow demand by combining the flow of the target video flow. And if the total required amount of the second flow exceeds the upper opening limit of the inlet flow control assembly of the lower monitoring center, screening the video flow with the lowest priority level from the existing video flows to be used as the video flow to be closed. Further, the video stream with the lowest priority level may be screened out from the existing video stream and the target video stream as the video stream to be closed.
Referring to fig. 7 (a), the lower monitoring center B opens 3 flows currently, which are 4M, 1M, and 2M, respectively, and the bandwidth is 7M/S by accumulation. The target video stream is 8M, and the sum of the target video stream and the 8M is 15M. However, the upper limit of the open flow at the entrance of the current lower monitoring center is 14M, if 8M flows need to be opened, part of the existing video flows need to be closed, and 1 path of 4M video flows need to be closed according to priority, see fig. 7 (b). In some cases, it may be necessary to close multiple video streams, for example, when the newly opened video stream is greater than 12M and less than or equal to 13M, such as 13M and 12.5M, 1 way of 5M video stream and 2 ways of 1M video stream need to be closed. If the newly opened video stream is larger than 13M and smaller than 15M, all opened video streams need to be closed.
Further, the lower monitoring center inlet flow control component can also transmit the video stream to be closed to the stream caller in a list form, and inform the stream caller of other video stream information closed by the open flow target video stream. Or before/after closing the video stream, the information of the current video stream is informed to the stream caller in the form of a list.
Similarly, for the flow control component at the outlet of the subordinate monitoring center, the existing fourth stream information sum on the outlet of the current subordinate monitoring center is calculated, and the total flow demand is calculated by combining the flow demand of the target video stream. And if the video stream exceeds the upper open stream limit, the video stream with lower priority level needs to be screened from the fourth stream information (and the target video stream), and a video stream list to be closed of the current monitoring center is returned.
In the above, in the case that the flow caller is only the lower level monitoring center, for the scenario that the flow caller is the upper level monitoring center, the limitation of the inlet and the outlet of the upper level monitoring center needs to be passed, specifically, see fig. 8:
s801: acquiring current third switching information of a lower monitoring center inlet, and processing the third switching information based on priority sequencing and the current limiting condition of the lower monitoring center inlet so as to transmit the target video stream to a lower monitoring center outlet;
s802: acquiring current fourth streaming information of an outlet of a lower monitoring center, and processing the fourth streaming information based on priority sequencing and a current limiting condition of the outlet of the lower monitoring center so as to transmit the target video stream to an inlet of a higher monitoring center;
s803: acquiring current fifth open flow information of an inlet of a superior monitoring center, and processing the fifth open flow information based on the current limiting condition and priority sequencing of the inlet of the superior monitoring center so as to transmit the target video to an outlet of the superior monitoring center;
s804: and acquiring current sixth open flow information of an outlet of a superior monitoring center, and processing the sixth open flow information based on the current limiting conditions and the priority sequence of the outlet of the superior monitoring center.
Under the condition that the flow calling party is a lower monitoring center, the cascade relation between the outlet of the lower monitoring center and the inlet of a higher monitoring center is not established, but if the flow calling party is the higher monitoring center, the cascade relation exists between the outlet of the lower monitoring center and the inlet of the higher monitoring center.
The method provided by the embodiment of the invention designs a current limiting service component, flexibly defines the priority of various video streams according to the service attributes, and limits the current based on the priority of the video streams instead of simply calling the service information of the open flow interface, thereby realizing the rapid analysis and carding of the flow, improving the processing accuracy and reducing the current limiting cost.
In the scheme, the key parts are similar to the central data structure, and the core work comprises the following aspects:
1. an appropriate data structure and storage mechanism is selected for storage and retrieval.
2. When an operation step in the core flow is abnormal, for example, an open flow request is lost, all the previous involved operations need to be rolled back, so as to roll back the open flow information of the key part and the monitoring center to the state of not processing the open flow request, and if necessary, the re-processing of the open flow request can be abandoned.
3. The problem of inconsistent data in a high-speed switching flow scene is solved: if two open flow requests are received in a very short time, the first open flow request may not be processed completely when the second open flow request is processed, that is, the open flow information of the important part and the monitoring center is not updated completely, and the second open flow request may be processed inaccurately, and the two open flow requests may collide with each other. In this case, after the first open flow request is processed and the open flow information is updated, the second open flow request may be processed, or the second open flow request may not be processed.
The maintenance of data consistency is crucial to the flow control component for storing video stream information and calculating a flow control rule, and the efficiency of high-frequency switching stream is also considered.

1. and the key part flow control module is used for determining key part information in the main information of the target video stream when the stream calling party initiates an open stream request for the target video, calling the video stream information storage module to compare the flow required by the target video stream, and calling the priority ordering module to preferentially close the video stream with the lowest priority when the flow exceeds the flow.
2. And the monitoring center flow control module is used for determining monitoring center information in the main information of the target video stream when a stream calling party initiates an open stream request for the target video, calling the video stream information storage module to compare the flow rate required by the target video stream, and calling the priority ordering module to preferentially close the video stream with the lowest priority when the flow rate exceeds the flow rate.
3. And the video stream information storage module stores various video stream information and merges the video stream information according to the monitoring center and the key parts.
4. The priority calculation module is used for quickly sequencing the video streams according to the priority of the video streams;
5. the sorting module belongs to an auxiliary module, and a very mature stream priority sorting algorithm is available at present.
