The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or to implicitly indicate the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present disclosure, "a plurality" means two or more unless otherwise specified.

The main factors influencing the QoS/QoE of the IPTV video service include: packet loss, disorder, jitter, delay (network end-to-end) of IP packets/packets. Packet loss, disorder, jitter, and (network end-to-end) cause phenomena such as screen splash, mosaic, and screen blackout of images displayed at the user terminal, thereby affecting the income and public praise of operators. At present, each operator urgently needs a scheme for monitoring video quality and positioning problems, can monitor and maintain service quality in real time, and quickly delimitates and clears responsibility when problems occur.

Therefore, the embodiment of the disclosure provides a video diagnosis method, which monitors the quality of multicast video services according to a monitoring request, sends a monitoring log to a video diagnosis server, and finally determines a network of video faults according to the monitoring log. Because the monitoring point is built in the service quality monitoring equipment (IP network equipment) or even a board card of the IP network equipment, when specific problems are determined, the monitoring point can be directly positioned on the IP network equipment or even on a specific board card of the IP network equipment, the investigation range is smaller, and the problem source can be determined more conveniently so as to solve the problems in time. The IP network equipment for bearing the IPTV comprises metropolitan area network equipment, access network equipment, home network equipment and the like.

The video diagnosis method may be applied to a server or a server cluster, and is not limited herein.

In some embodiments, the quality of service monitoring device 11 includes a quality of service monitoring device 11a, a quality of service monitoring device 11b, and a quality of service monitoring device 11c. The service quality monitoring device 11a may be an Optical Line Terminal (OLT), the service quality monitoring device 11b may be an Optical Network Terminal (ONT), an Optical Network Unit (ONU), and the service quality monitoring device 11c may be a metropolitan area Network device, such as a Service Router (SR), a core router, and the like. The OLT and the ONT/ONU are connected through an optical splitter. An EMS (Element Management System) is used to manage one or more network devices, such as OLT, ONT/ONU. The ONT/ONU may be HGU (Home g gateway), MDU (Multi Dwelling Unit), etc. The OLT, the ONT/ONU and the Optical splitter form a Passive Optical Network (PON).

The video diagnosis server 12 is configured to receive a monitoring result sent by a service quality monitoring device; and determining the network with video fault according to the monitoring result. In some embodiments, the video diagnosis server 12 may be a single server, or may be a server cluster composed of a plurality of servers, which is not limited in this disclosure.

As an implementation manner, the video diagnosis server 12 is further configured to receive a monitoring result sent by the EMS; and determining the network with video fault according to the monitoring result. And the monitoring result sent by the EMS comes from the OLT equipment and the ONT/ONU. The OLT equipment, the ONT/ONU and the EMS communicate through a management protocol. The EMS may be a server. Namely: the video diagnosis server 12 may also issue the monitoring request to the EMS, and the EMS sends the monitoring request to the OLT device and the ONT/ONU through the management protocol. The OLT device and the ONT/ONU transmit the (service) monitoring log and the (service) monitoring result to the EMS through the management protocol, and then the EMS reports the (service) monitoring log and the (service) monitoring result to the video diagnostic server 12.

After the application scenario and the implementation environment of the embodiment of the present disclosure are introduced, the video diagnosis method provided by the embodiment of the present disclosure is described in detail.

Fig. 2 is a flow chart illustrating a method of video diagnosis according to an exemplary embodiment, when the method is applied to a quality of service monitoring device, as shown in fig. 2, the method may include steps 201 to 203:

step 201, the service quality monitoring device obtains a monitoring request.

Wherein, the monitoring request includes the information of the multicast video service; the monitoring request is used for requesting to monitor the multicast video service.

In the step, an EMS and/or a video diagnosis server appoints one or all board cards of the OLT to monitor, the OLT starts monitoring and stops monitoring multicast programs along with the OLT multicast module according to the program-on-demand condition, monitors the IPTV data flow of an incoming board card for an uplink board card, and monitors the IPTV data flow of an outgoing board card for a PON service board card. And a monitoring board card and a program section are designated for monitoring, wherein the monitoring board card can be an uplink port of the OLT, a PON service board card and the monitoring board card is used for fixedly detecting the designated program section. And the ONT is appointed to monitor, and the ONT starts monitoring and stops monitoring the multicast program along with the ONT multicast module according to the program ordering condition of the port of the ONT.

Step 202, the service quality monitoring device executes monitoring of the multicast video service according to the information of the multicast video service, and generates and stores a monitoring log.

The monitoring log comprises monitoring data of the multicast video service.

In this step, the service quality monitoring device monitors the video service according to the multicast video service information included in the monitoring request, and finally generates a monitoring log.

The step of monitoring the multicast video service is executed according to the multicast video service information, and monitoring equipment is different according to the executed service quality, so that the monitoring step is different.

As shown in fig. 3, when the executed service quality monitoring device is an OLT, a specific execution monitoring process includes:

step 2021a, the service quality monitoring device captures a video stream according to the multicast video service information.

The multicast video service information comprises a virtual local area network ID of the multicast video service and a destination IP address of the multicast video service.

Illustratively, the monitoring points in the upstream board card and the PON board card in the service quality monitoring device (e.g., OLT device) copy video streams at corresponding addresses according to the video service information.

And after the OLT acquires the monitoring request, analyzing a packet header of an IP layer and an MAC frame header of an MAC layer of the monitoring request message, and acquiring a target IP address and a virtual local area network (ID) of video service information contained in the monitoring request.

The identification information of the video service information may also be other one or more elements in the five-tuple or a combination of other one or more elements in the five-tuple and the VLAN ID. For example: the "destination IP address", "destination port", and VLAN ID may be used as the classification condition for traffic classification, and the "destination IP address", "protocol number", and VLAN ID may also be used as the classification condition for traffic classification, where the protocol number is used to identify the type of protocol.

Step 2022a, the service quality monitoring device monitors the video stream, and determines a monitoring Index of the video stream through an Enhanced Media Delivery Index (eMDI).

Illustratively, the monitoring points in the uplink board card and the PON service board card in the service quality monitoring device OLT copy video streams at corresponding addresses according to the video service information, and perform eMDI calculation for the video streams.

Currently, in an interactive network television (IPTV) system, streaming technologies mainly used are mainly an internet streaming media alliance mode and an MPEG-2TS over IP mode.

The Internet Streaming Media Alliance (ISMA) is a standardization organization established in 12 months of 2000, aiming at establishing an open standard among Internet Streaming Media encoders, servers and players, the principle of which is to make the most use of the existing Internet international standard.

The MPEG-2TS (Transport Stream) over IP method also adopts the structure of server/client. Since the ISO/IEC 13818-1 standard does not define a control layer Protocol, after the application to IPTV, the MPEG-2TS over IP method may use Real Time Streaming Protocol (RTSP) or HyperText Transfer Protocol (HTTP) in the control layer. Media data is encapsulated by MPEG-2TS and is typically carried over User Datagram Protocol (UDP). For network jitter, etc., transport Stream (TS) packets may be encapsulated using real-time Transport protocol (RTP) over UDP.

Based on the above two streaming technologies, the general IPTV packet structure mostly carries RTP headers. RTP is defined in RFC1889 and is used to provide end-to-end real-time transport services for various multimedia data requiring real-time transport, such as voice, image, fax, etc., over an IP network. In general, RTP is carried over UDP. Among them, domestic operators mainly adopt IPT V architecture based on MPEG-2TS mode of RTP encapsulation.

Because the eMDI supports detection of UDP-based RTP video streams, an eMDI algorithm is used to perform the calculation of the indicator of video traffic quality. When the eMDI algorithm is used for detection, a matched multicast video flow message is obtained, the NP of a detection single board carries out validity check and RTP protocol check on the IP head, the UDP head and the RTP head information of an RTP message, then packet loss and disorder calculation is carried out according to the serial number in the RTP head, and jitter calculation is carried out according to the timestamp in the RTP head, so that real-time monitoring on video quality is realized.

The eMDI is a scheme for on-board detection. When the scheme is deployed, a video service (program) to be detected is added into a video service group (program group), then a single board with a monitoring function (equivalent to an uplink board card of the OLT and a PON service board card of the OLT) is added into the single board group, and finally the video service group is bound with the single board group, so that the monitoring of the video stream of the specified video service group is realized through the monitoring single board.

Meanwhile, the eMDI is a detection mode which is based on end-to-end and can directly measure the specified multicast video service messages on each network node in the IP network so as to obtain performance indexes such as real packet loss rate, disorder rate, jitter and the like, and the eMDI has the outstanding advantages of convenience in deployment, comprehensive coverage of network elements, high statistical accuracy and the like.

Specifically, the index acquisition mode of the service carried by the eMDI based on the UDP is as follows:

based on analysis of RTP packets. The RTP message consists of a message header and a payload. In the calculation of the UDP monitoring index, different services are distinguished by analyzing a PT field in an RTP message header, the packet loss rate and the disorder rate are calculated by a serial number in the RTP message header, and the jitter is calculated by a timestamp in the RTP message header.

The eMDI defines the indicators that measure video quality as shown in the following table:

and through calculation of an eMDI algorithm, a monitoring index of video service quality is obtained.

As shown in fig. 4, when the executed service quality monitoring device is an ONT, the specific execution monitoring process includes:

step 2021b, the service quality monitoring device performs video stream packet capturing according to the multicast video service information; the multicast video service information comprises a virtual local area network ID of the multicast video service and a destination IP address of the multicast video service.

In this step, the monitoring point of the service quality monitoring device ONT performs video stream packet capture according to the multicast video service information. For a detailed description of the video service information see the description in 2021 a.

The ONT acquires corresponding video service information according to the quintuple rule, and captures the corresponding video on demand according to the video service information.

Step 2022b, the service quality monitoring device adds a timestamp and an IP packet sequence number to the video stream of the packet capture.

In this step, the service quality monitoring device ONT adds a timestamp and an IP packet sequence number to the video stream after packet capture. And sending the video stream added with the timestamp and the IP packet sequence number to a corresponding monitoring module.

Step 2023b, the service quality monitoring device determines the monitoring index of the video stream added with the timestamp and the IP packet sequence number through the enhanced media transmission quality index eMDI.

In this step, the monitoring index of the video service quality can be calculated through the eMDI algorithm. See the description in 2022a for a detailed description of the eMDI calculation index section.

Step 203, the service quality monitoring device sends the monitoring log to the video diagnosis server.

And the monitoring log is used for determining the position of the video fault according to the monitoring data.

In this step, a monitoring log is generated from the calculated monitoring index, and the monitoring log is periodically uploaded to the video diagnosis server. For example, when a single board (an uplink board or a PON service board) of the OLT or the ONT monitors a video fault, a monitoring log is generated and stored in the OLT main control board. When program quality is judged, a fault monitoring log is generated every 60s, all fault logs are screened every 5 minutes, and the worst monitoring log record is selected, stored and reported to the video diagnosis server.

According to the video diagnosis method provided by the disclosure, a plurality of monitoring points are built in a monitoring device, multicast video service information to be monitored is sent to the monitoring points, the monitoring points capture video streams according to the multicast video service information to perform relevant calculation, a monitoring log is obtained, and the monitoring log is uploaded to a video diagnosis server. Because the monitoring point is built-in monitoring facilities's integrated circuit board, when determining concrete problem, can directly fix a position on the network that the integrated circuit board corresponds, the scope of investigation is littleer, more does benefit to and determines the problem source to in time solve. Meanwhile, the method is simpler and more convenient, low in learning cost and wider in applicability.

Fig. 5 is a flowchart illustrating a method for video diagnosis according to an exemplary embodiment, when the method is applied to a video diagnosis server, as shown in fig. 5, the method may include steps 501 to 502:

step 501, the video diagnosis server receives a monitoring log sent by a service quality monitoring device.

The monitoring log comprises monitoring data of the multicast video service.

In this step, the video diagnosis server receives the monitoring log sent by the service quality monitoring device.

Step 502, the video diagnosis server determines the position of the video fault according to the monitoring log.

In this step, the video diagnosis server determines the position of the video fault according to the monitoring log.

Specifically, as shown in fig. 6, step 502 further includes steps 5021-5026.

Step 5021, if the first monitoring point of the service quality monitoring equipment detects that the video stream has quality problems, the first network is checked.

Specifically, the diagnosis method may be adjusted according to the number of monitoring points set in a specific OLT or ONT. For example, after the upstream board of the OLT, the PON service board of the OLT, and the ONT/ONU device respectively set monitoring points, the specific diagnosis process is as follows:

if the first monitoring point is located at an uplink board card of the OLT, and the quality problem of the IPTV video stream of the uplink board card is determined according to the monitoring log (for example, an eMDI parameter shows that the RTP message has packet loss, disorder and the like), and a calculation result is stored. And sending a monitoring result to the network manager and/or the monitoring system, wherein the monitoring result is as follows: and prompting to investigate an upper network of the OLT, such as a metropolitan area network, and alarming at the same time.

Step 5022, if the first monitoring point has no problem, the second monitoring point of the service quality monitoring equipment is checked.

Illustratively, if the first monitoring point is located at an upstream board card of the OLT and it is determined according to the monitoring log that there is no quality problem in the IPTV video stream of the upstream board card, the calculation result is saved, the monitoring result is sent to the network manager and/or the monitoring system, and a second monitoring point for checking the service quality monitoring device is prompted, where the second monitoring point may be located at a downstream board card of the OLT (i.e., a PON service board card).

Step 5023, if the second monitoring point detects that the video stream has quality problems, the access network between the first network and the second network is checked.

Exemplarily, if the second monitoring point of the downstream board of the OLT (i.e. the PON service board card) determines that the IPTV video stream of the downstream board has a quality problem according to the monitoring log, store the calculation result, and send the monitoring result to the network manager and/or the monitoring system, where the monitoring result is: the OLT sends out a master board fault alarm (usually, a master network processor loses packets and goes out of order), and simultaneously alarms.

Step 5024, if the second monitoring point has no problem, the third monitoring point of the service quality monitoring equipment is checked.

For example, if the second monitoring point of the downstream board of the OLT (i.e., the PON service board) determines that there is no quality problem in the IPTV video stream of the downstream board according to the monitoring log, send a monitoring result to a network Management system (e.g., EMS) and/or a monitoring system, and send a command for monitoring the IPTV video stream to a third monitoring point of the service quality monitoring device through messages such as an optical network unit Management and Control Interface (OMCI), where the third monitoring point may be located on an ONT on the user side.

Step 5025, if the third monitoring point detects that the video stream has quality problems, the access network from the second network to the third network is checked.

Exemplarily, if the third monitoring point of the ONT determines that the IPTV video stream of the ONT has a quality problem according to the monitoring log, the third monitoring point stores the calculation result, and sends the monitoring result to the network manager and/or the monitoring system, where the monitoring result is: and a downstream board fault alarm of the OLT (generally, congestion and packet loss and disorder of a PON port) and alarm at the same time.

Step 5026, if the third monitoring point has no problem, the home network of the user is checked.

Illustratively, if the third monitoring point of the ONT determines that the IPTV video stream of the ONT has no quality problem according to the monitoring log, the third monitoring point stores the calculation result, and sends the monitoring result to the network manager and/or the monitoring system, where the monitoring result is: prompting to investigate the user's home network, especially the ports where the ONT is connected to the set-top box.

According to the video diagnosis method provided by the disclosure, the monitoring point uploads the monitoring log to the video diagnosis server, and the video diagnosis server judges the monitoring result according to the monitoring log according to a certain diagnosis method, so that the network with the video fault is finally determined. The video diagnosis server can realize active operation and maintenance according to the monitoring logs uploaded by the monitoring points, carry out real-time monitoring on network indexes (packet loss/disorder) aiming at the video programs and provide real-time guarantee for users.
