[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The figure numbers in this application are only used to distinguish the various steps in the scheme, and are not used to limit the execution order of the various steps. The specific execution order is subject to the description in the specification.

[0031] In the scenario of online video playback, if the video playback is stuck, it will affect the user experience. In order to detect the situation of the previous video being stuck, it can be achieved by analyzing the stuck characteristics of the signaling message during the viewing process.

[0032] Specifically, during the video viewing process, two signaling messages, namely, the start of the freeze and the end of the freeze, are generated. The signaling messages are obtained by simulating freeze analysis by watching the video in real time, and the freeze duration is the difference between the timestamps of the two signaling messages.

[0033] The signaling messages in this solution are not standardized, and the detection accuracy is highly dependent on the specific video application. The characteristics of each application are different, and once the characteristics in the video application signaling message change, the jam detection will fail, and there will be great difficulties in collection and maintenance.

[0034] In addition to the above solution, the video application provider can also collect information about the freeze of the client watching the video through the content source server. This solution cannot guarantee the coverage of home broadband users. For example, the A video application software can collect the freeze of all terminals playing videos through the A video application through its own application data server, but it is impossible to guarantee that all families in the same community use the A video application to watch videos. Moreover, the relevant logs are not standardized records, and there are differences in the log records of different video providers, making it difficult to normalize and analyze actual use.

[0035] Moreover, it is often difficult to detect freezes in videos transmitted in P2P mode, and the detection results often do not match the actual viewing experience of users.

[0036] In order to solve the problems existing in the prior art, the embodiment of the present application provides a video freeze detection method based on HTTP and P2P transmission, which can be applied to home broadband networks or other scenarios of playing online videos. In the home broadband network scenario, it can be used to identify users with poor home broadband quality, and then through active operation and maintenance, improve the operator's user satisfaction, reduce user churn, and improve the operator's reputation.

[0037] In this embodiment, the present application scheme is applied to a home broadband network for further explanation. Figure 1a The application scenario of this solution is shown. Among them, the Broadband Remote Access Server (BRAS) is a new access gateway for broadband network applications. The analysis server is a device in the network that supports home broadband video freeze detection and analysis. Figure 1b The internal structure diagram of BRAS is shown. Figure 1c A schematic diagram of the internal structure of the analysis server is shown.

[0038] The present application embodiment provides a video freeze detection method based on HTTP and P2P transmission, such as Figure 1d As shown, this program includes:

[0039] S11: Obtain the transmission log of the video to be detected, wherein the transmission log includes the fragmentation information of the video to be detected, HTTP fragmentation video acquisition request information and P2P fragmentation video transmission data volume, and the fragmentation information includes the data volume and playback duration of multiple fragmentation videos in the video to be detected.

[0040] In the embodiment of the present application, based on Figure 1a In the application scenario shown, the execution subject of this solution can be an analysis server. In actual application, the transmission log of the video to be detected can be obtained by BRAS using a packet capture tool and transmitted to the analysis server so that the analysis server can perform subsequent processing and analysis on the transmission log.

[0041] The online video in this solution is played based on Hyper Text Transfer Protocol (HTTP) technology and peer-to-peer (P2P) technology.

[0042] The online video in this solution is played online through the HLS (HTTP Live Streaming) video request method. HLS is a streaming network transmission protocol based on HTTP. Its working principle is to divide the entire stream into small HTTP-based files for download, and only download a few at a time. Specifically, it includes an m3u (8) index file, TS (Transport Stream) media segment file and key encryption string file.

[0043] The above-mentioned P2P is a distributed network, in which participants of the network share a part of their hardware resources. These shared resources need to be provided with services and content by the network and can be directly accessed by other peer nodes (peers) without going through an intermediate entity.

[0044] In this step, the transmission log of the video to be detected is obtained, which may include the above-mentioned m3u (8) index file, which can be used to determine the video resource address and request to obtain the segmented video. The transmission log may also include a TS media segment file, and the segment information of the video to be detected can be determined by parsing the TS media segment file, specifically including the data volume and playback duration of multiple segmented videos in the video to be detected.

[0045] In actual applications, the BRAS program component can record the playlist information, the playing time of each segment video, the requested URL, the data volume contentlength, and the segment video sequence number sd. Among them, contentlength and sd are cumulative values, and the number of the currently playing segment video can be obtained by conversion.

[0046] When users watch online videos, the user terminal will request video files in HTTP mode. After a certain amount of requests, it will stop requesting video files in HTTP mode. At this time, there are no video file request and response messages from the packet capture tool. However, packet analysis shows a large amount of UDP (User Datagram Protocol) protocol transmission, with a large number of uplink and downlink packets and bandwidth occupancy. This UDP transmission protocol can be identified by the DPI device as the transmission data volume of online videos watched through P2P transmission through playback.

[0047] S12: Determine a play period of the target segmented video according to the transmission log, and a start time of the play period of the target segmented video is determined according to an HTTP segmented video acquisition request of the target segmented video.

[0048] Based on the above transmission log, the video to be detected that the user wants to watch online, the segment information of the video to be detected, the transmitted HTTP request, and the data volume of P2P transmission can be determined. Among them, the total number of segments of the video to be detected and the data volume of each segment are unchanged. They can be obtained according to the m3u8 list or the relevant information of the video to be detected.

[0049] In this step, for the target segmented video in the video to be detected, the video playing length of the target segmented video is determined, that is, how long it takes for the user to actually watch the target segmented video. The moment when the user starts playing the target segmented video can be inferred based on the HTTP request, and then the playing period of the target segmented video is determined.

[0050] In practical applications, in order to determine the playback period of the target segmented video, a video node can be established to simulate the process of users watching videos and improve the accuracy of detecting video freezes. The video node can record the playback time and file request size of each video segment.

[0051] S13: Determine the amount of P2P segmented video transmission data that has been transmitted before the end time of the playback period of the target segmented video according to the transmission log.

[0052] In this step, the amount of transmitted P2P segmented video transmission data refers to the amount of downlink data of the target segmented video that has been transmitted in a P2P manner.

[0053] In practical applications, if you want a video to be played smoothly without lag, you need to preload at least part of the video before playing it. In other words, the amount of data of the loaded video should be greater than the amount of data of the already played video, so as to ensure that the video is not stuck.

[0054] In this step, the amount of P2P segmented video transmission data transmitted before the end time of the target segmented video playback period is obtained. If the video watched by the user is played smoothly, then at the above end time, the amount of P2P segmented video transmission data transmitted must be greater than the target segmented video, that is, the download of this target segmented video is completed before the target segmented video is played.

[0055] S14: If the amount of data transmitted by the transmitted P2P segmented video is less than the amount of data of the target segmented video, it is determined that the video to be detected is stuck during the playback period of the target segmented video.

[0056] In this step, the amount of data transmitted through the P2P method is compared with the amount of data of the target segment video. If the amount of data transmitted does not reach the amount of data of the target segment video at the estimated end time of the target segment video playback, it can be determined that the target segment video has not been completely transmitted before the above end time. In other words, a freeze occurs during the estimated playback period of the target segment video.

[0057] In an embodiment of the present application, by obtaining the transmission log of the video to be detected, the transmission log includes the fragmentation information of the video to be detected, the HTTP fragmentation video acquisition request information and the P2P fragmentation video transmission data volume, and the fragmentation information includes the data volume and playback duration of multiple fragmentation videos in the video to be detected; the playback period of the target fragmentation video is determined according to the transmission log, and the starting time of the playback period of the target fragmentation video is determined according to the HTTP fragmentation video acquisition request of the target fragmentation video; the P2P fragmentation video transmission data volume that has been transmitted before the end time of the playback period of the target fragmentation video is determined according to the transmission log; if the P2P fragmentation video transmission data volume that has been transmitted is less than the data volume of the target fragmentation video, it is determined that the video to be detected is stuck during the playback period of the target fragmentation video. In this scheme, the data volume of the target fragmentation video is compared with the data volume that has been transmitted. If the data volume that has been transmitted has not reached the data volume of the target fragmentation video after the playback period of the target fragmentation video ends, it can be determined that the target fragmentation video has not been fully transmitted within the expected playback period, and then it can be determined that the actual playback has been stuck. Through the solution provided by this application, the real experience of users watching videos can be determined based on the transmission log analysis, and whether the video playback is stuck can be determined based on the amount of data transmitted, effectively improving the accuracy of the stuck judgment. Moreover, this solution can determine whether the video playback is stuck based on the transmission log, avoiding occupying the user's bandwidth and affecting the user's experience of other network services.

[0058] Based on the solution provided in the above embodiment, optionally, Figure 2 As shown, the above step S13 includes:

[0059] S21: parsing the transmission log to obtain the UDP protocol transmission data volume and the corresponding timestamp;

[0060] S22: Determine the transmitted P2P segmented video transmission data volume according to the UDP protocol transmission data volume whose timestamp is before the end time of the playback period of the target segmented video as the transmitted P2P segmented video transmission data volume.

[0061] In the solution provided in the embodiment of the present application, the transmission log is parsed to obtain the data volume and corresponding timestamp transmitted by the UDP protocol, so as to determine the data volume that has been transmitted through the P2P method. Optionally, the HTTP request and response can also be combined to assist in improving the accuracy of the determined P2P segmented video transmission data volume that has been transmitted.

[0062] Based on the solution provided in the above embodiment, optionally, Figure 3 As shown, after the above step S14, it also includes:

[0063] S31: Determine the duration of the freeze of the video to be detected during the playback period of the target segmented video based on the data volume of the target segmented video, the playback duration of the target segmented video, and the amount of P2P segmented video transmission data that has been transmitted before the end time of the playback period of the target segmented video.

[0064] In the solution provided in the embodiment of the present application, after determining that the target segment video has a freeze during the playback period, the freeze duration can be further estimated. The freeze duration can be used to assist in optimizing the online video playback service and the user experience.

[0065] For example, assuming that the target segmented video data volume of the video to be detected is 1821720 (bytes), the target segmented video playback duration is 9s, and the P2P data volume requested during the playback time period corresponding to the target segmented video is 1300480 (bytes). Since the amount of data transmitted, 1300480 (bytes), is less than the amount of data of the target segmented video, 1821720 (bytes), it can be determined that the target segmented video has been stuck during playback. The duration of playback can be calculated based on the ratio of the amount of data downloaded to the amount of data of the target segmented video and the product of the playback duration of this segmented video, and then the duration of the unplayed video can be determined. The duration of this unplayed video is the duration of the stuck within 9s of the target segmented playback period.

[0066] Based on the solution provided in the above embodiment, optionally, Figure 4 As shown, the above step S31 includes:

[0067] S41: When the cache duration before the start time of the playback period of the target segmented video is a positive value, the freeze duration of the target segmented video is determined according to the following formula:

[0068] The duration of the freeze during the playback period of the target segmented video = the playback period of the target segmented video × (1-the amount of P2P segmented video transmission data transmitted during the playback period of the target segmented video / the amount of data of the target segmented video)-the cache duration before the start time of the playback period of the target segmented video.

[0069] In the embodiment of the present application, the cache duration is the difference between the total duration of the playback of the historical segmented videos before the start time of the playback period of the target segmented video and the total duration of the historical segmented videos transmitted by the P2P segmented video.

[0070] For example, through the above steps, it is determined that the first HTTP request segment video playback time in the video playlist of the video to be detected is 9 seconds. A video node is established based on the video to be detected to simulate the process of users watching videos while downloading. Assuming that the download time of the first segment video is only 8 seconds, the video node playback cache time is 1 second. The data of the second segment video can continue to be loaded during this cache time.

[0071] Assume that the data volume of the second segment video is 1821720 (bytes), the playback duration of the second segment video is 9 seconds, and the amount of P2P data requested during the 9-second playback period is 1270 kB. Since the amount of downloaded data is less than the amount of data of the second segment video, it can be determined that a freeze event occurred in this video segment.

[0072] The duration of the jamming is determined by the solution provided in the embodiment of the present application as follows:

[0073] Segmented video playback duration*(1-(P2P data volume*1024) / segmented video expected data volume)-video node playback cache time=1.575s

[0074] In this step, 1270 kB is multiplied by 1024 and converted into bytes to match the measurement unit of the amount of data downloaded.

[0075] Through the solution provided by the embodiment of the present application, after determining that the video is stuck, the length of time that the stuck occurs during the target segment playback period can be calculated. Since the solution determines the stuck duration based on the amount of data actually transmitted by the user network, it can accurately reflect the user's real viewing experience.

[0076] Based on the solution provided in the above embodiment, optionally, Figure 5 As shown, the method also includes:

[0077] S51: If the amount of data transmitted by the P2P segmented video during the playback period of the target segmented video is greater than or equal to the amount of data of the target segmented video, determining that the video to be detected is not stuck during the playback period of the target segmented video;

[0078] S52: Determine the playback cache duration of the video node according to the playback duration of the target segmented video and the download duration of the target segmented video.

[0079] Based on the above embodiment, if within the second segmented video, i.e. within 9 seconds, the amount of data requested by P2P is equal to the size of the segmented video in the playlist, it indicates that the second segmented video has been transmitted before it is played, thereby determining that there is no lag in the second segmented video during playback.

[0080] Since the download of this segmented video has been completed before the second segmented video is played, the difference between the download time and the playback time can be used to transmit the subsequent segmented video, so the above time difference (segmented video playback time - P2P data download time) can be accumulated as the playback cache time. The playback cache time can be used to determine whether the subsequent segmented video is stuck.

[0081] Based on the solution provided in the above embodiment, optionally, Figure 6 As shown, the transmission log includes HTTP segmented video acquisition request information in a compressed state;

[0082] After the above step S11, the method further includes:

[0083] S61: decompressing the compressed HTTP segmented video acquisition request information in the transmission log;

[0084] S62: Establishing a video node corresponding to the video to be detected according to the decompressed HTTP segmented video acquisition request information;

[0085] Wherein, the above step S12 includes:

[0086] S63: Determine the start time of the play period of the target segmented video according to the HTTP segmented video acquisition request information, and simulate the play of the target segmented video according to the video node to determine the play period of the target segmented video.

[0087] In actual applications, HTTP request data is often chunked and compressed in gzip format. Through the embodiments of the present application, the data can be reorganized and decompressed to restore the data, thereby establishing a video node that matches the video to be detected and executing a subsequent judgment on video playback freezes.

[0088] Based on the solution provided in the above embodiment, optionally, Figure 7 As shown, the above step S11 includes:

[0089] S71: If an access action to the video to be detected is monitored, the network transmission log is monitored to obtain the transmission log of the video to be detected.

[0090] The solution provided by the embodiment of the present application can be executed after the user actively triggers the action of playing online videos. By monitoring the video access action, it can be timely and accurately detected that the user wants to watch online videos. Then, the network transmission log is monitored in time to achieve real-time detection of the user's online video viewing. If it is detected that the user frequently freezes when watching online videos, the home bandwidth where the video freezes can be optimized to optimize the user experience.

[0091] Through the solution provided by the embodiment of the present application, the accurate identification of video application traffic and the simulation of the playback of general streaming media videos can accurately identify the video freeze of home broadband users in the mixed HTTP+P2P scenario, helping operators to timely identify users with poor experience in the network. Operators can use this data as a basis to take active care of users with poor experience, reduce customer churn, and improve their own reputation.

[0092] By applying the solution provided in the embodiment of the present application, it is also possible to analyze specific popular video applications with more freezes based on the video freeze data of the entire network, and introduce video resources into the network in a targeted manner, such as adding video servers, providing popular application caches, etc., which has certain guiding significance for the operator's resource investment.

[0093] In order to solve the problems existing in the prior art, the embodiment of the present application further provides a video freeze detection device 80 based on HTTP and P2P transmission, such as Figure 8 As shown, including:

[0094] An acquisition module 81 acquires a transmission log of a video to be detected, wherein the transmission log includes segmentation information of the video to be detected, HTTP segmentation video acquisition request information, and P2P segmentation video transmission data volume, wherein the segmentation information includes data volume and playback duration of multiple segmentation videos in the video to be detected;

[0095] A first determining module 82 determines a play period of a target segmented video according to the transmission log, wherein a start time of the play period of the target segmented video is determined according to an HTTP segmented video acquisition request of the target segmented video;

[0096] A second determination module 83 determines the amount of P2P segmented video transmission data that has been transmitted before the end time of the playback period of the target segmented video according to the transmission log;

[0097] The third determination module 84 determines that the video to be detected is stuck during the playback period of the target segmented video if the transmission data volume of the transmitted P2P segmented video is less than the data volume of the target segmented video.

[0098] The device provided by the embodiment of the present application obtains the transmission log of the video to be detected, the transmission log includes the fragmentation information of the video to be detected, the HTTP fragmentation video acquisition request information and the P2P fragmentation video transmission data volume, and the fragmentation information includes the data volume and playback duration of multiple fragmentation videos in the video to be detected; the playback period of the target fragmentation video is determined according to the transmission log, and the starting time of the playback period of the target fragmentation video is determined according to the HTTP fragmentation video acquisition request of the target fragmentation video; the P2P fragmentation video transmission data volume that has been transmitted before the end time of the playback period of the target fragmentation video is determined according to the transmission log; if the P2P fragmentation video transmission data volume that has been transmitted is less than the data volume of the target fragmentation video, it is determined that the video to be detected is stuck during the playback period of the target fragmentation video. In this scheme, the data volume of the target fragmentation video is compared with the data volume that has been transmitted. If the data volume that has been transmitted has not reached the data volume of the target fragmentation video after the playback period of the target fragmentation video ends, it can be determined that the target fragmentation video has not been fully transmitted within the expected playback period, and then it can be determined that the actual playback has been stuck. Through the solution provided by this application, the real experience of users watching videos can be determined based on the transmission log analysis, and whether the video playback is stuck can be determined based on the amount of data transmitted, effectively improving the accuracy of the stuck judgment. Moreover, this solution can determine whether the video playback is stuck based on the transmission log, avoiding occupying the user's bandwidth and affecting the user's experience of other network services.
