[0002] From the host pushing the stream upstream to the audience pulling the stream downstream for viewing, the live stream will pass through a series of host nodes of different roles (CDN streaming edge node ->…-> CDN viewing edge), where each role is a cluster. Therefore, the specific nodes through which the live stream flows are unclear, and it is necessary to clarify the specific nodes through which the live stream flows.

[0003] In the related technology, in order to improve the service quality of live broadcast services, it is necessary to monitor the service quality of live broadcast services.

The conventional method is to detect in turn whether there is processing information of the live broadcast stream in the log file of each node in each cluster that transmits the live broadcast stream, so as to determine whether the node has transmitted the live broadcast stream. Since each node processes a large amount of tasks and generates many log files, it is inefficient to determine whether the live broadcast stream flows through the node based on the log file, which reduces the efficiency of determining the live broadcast stream transmission path.

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0024] The embodiment of the present application provides a live streaming transmission method, which is applied to a live streaming transmission device. Figure 1 A flow chart of a live streaming transmission method provided in an embodiment of the present application is as follows: Figure 1 As shown, the live streaming transmission method may include:

[0025] S101, obtaining a first live stream transmitted by a streaming application end through at least one first node; the first live stream carries a tracing identifier, and the tracing identifier is used to identify at least one node through which the first live stream flows; the first live stream is a live stream obtained by adding a tracing identifier to a second live stream generated by a first node among the at least one first node.

[0026] A live streaming transmission method provided in an embodiment of the present application is suitable for a scenario in which transmission fault detection of a live streaming is performed.

[0027] In the embodiments of the present application, the live streaming transmission device can be implemented in various forms. For example, the live streaming transmission device described in the present application may include devices such as mobile phones, cameras, tablet computers, laptop computers, PDAs, portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, and devices such as digital TVs, desktop computers, and servers.

[0028] In the embodiment of the present application, the streaming application end is an application end used by the anchor for live broadcasting. The streaming application end may be an application program (Application, APP).

[0029] It should be noted that the second live stream is the live stream collected by the anchor during the live broadcast.

[0030] It should be noted that the streaming application end is an application end used by viewers when watching live broadcasts. The streaming application end may also be an APP.

[0031] In the embodiment of the present application, from the host's upstream streaming to the audience's downstream streaming, a live stream (such as the first live stream) will pass through a series of host nodes including: Content Delivery Network (CDN) streaming edge node -> source station forwarding -> transcoding / recording / screenshot -> CDN transit -> CDN secondary cache -> CDN viewing edge. Among them, each role is a cluster, that is, the CDN streaming edge node is a cluster, including multiple CDN streaming edge nodes; source station forwarding is also a cluster, including multiple source station forwarding nodes; transcoding / recording / screenshot is a cluster, including multiple transcoding / recording / screenshot nodes; CDN transit is a cluster, including multiple CDN transit nodes; CDN secondary cache is a cluster, including multiple CDN secondary cache nodes; CDN viewing edge is a cluster, including multiple CDN viewing edge nodes.

[0032] It should be noted that the live streaming transmission device can be any CDN transit node in the CDN transit cluster.

[0033] For example, Figure 2 As shown, when the anchor is broadcasting live, the second live stream is generated on the push stream application end, and the CDN push stream edge node adds a traceability mark in the second live stream to obtain the first live stream, and transmits the first live stream to the CDN transit node (live stream transmission device) through the live source station forwarding node and transcoding / recording / screenshot node (live source station screenshot recording node, live source station transcoding node, transcoding script). When watching the anchor's live broadcast, the audience needs to obtain the first live stream in the CDN transit node through the CDN pull stream edge node and the CDN secondary cache node, and transmit the first live stream to the pull stream application end for users to watch the live broadcast.

[0034] In the embodiment of the present application, the traceability mark can be a mark in character form, or a mark in digital form; the traceability mark can also be a mark in other forms; the specific traceability mark can be determined according to actual conditions, and the embodiment of the present application does not limit this.

[0035] Exemplarily, the traceability identifier may be TraceId. The data type of the access and mobility management function (AMF) is number.

[0036] In the embodiment of the present application, the traceability identifier is a unique identifier that identifies the first live stream.

[0037] In the embodiment of the present application, the first node is any node in the CDN streaming edge node cluster.

[0038] In the embodiment of the present application, the traceability identifier is an identifier determined according to the target connection identifier of the first node.

[0039] It should be noted that the target connection identifier of the first node may be an identifier of the connection relationship between the first node and the streaming application end, that is, the connection relationship identifier of the left connection of the first node.

[0040] It should be noted that the connection relationship between any two nodes corresponds to the connection identifier one by one, that is, one connection relationship corresponds to one connection identifier.

[0041] Exemplarily, the live stream s is transmitted from node A to node C via node B, and the left connection of node B is the connection relationship between node A and node B, and the connection relationship between node A and node B has one and only one connection identifier.

[0042] In the embodiment of the present application, the method for the live streaming transmission device to determine the traceability identifier according to the target connection identifier can be to use the target connection identifier as the traceability identifier; or it can be to use the configuration relationship between the preset connection identifier and the preset traceability identifier to determine the traceability identifier corresponding to the target connection identifier; the specific method for determining the traceability identifier according to the target connection identifier can be determined according to actual conditions, and the embodiment of the present application is not limited to this.

[0043] It should be noted that the configuration relationship between the preset connection identifier and the preset traceability identifier can be a relationship configured in the live streaming transmission device; the configuration relationship between the preset connection identifier and the preset traceability identifier can also be a relationship transmitted from other devices to the live streaming transmission device; the specific way in which the live streaming transmission device obtains the configuration relationship between the preset connection identifier and the preset traceability identifier can be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0044] It can be understood that by determining the target connection identifier of the first node, the target connection identifier is an identifier that uniquely identifies the connection relationship between nodes. A tracing identifier can be uniquely determined using the target connection identifier, and the first live stream is identified using the unique tracing identifier, so that the nodes through which the first live stream passes can be traced throughout according to the tracing identifier, that is, the nodes through which the first live stream passes can be determined, so that the transmission path of the first live stream can be quickly determined according to the nodes through which the first live stream passes, thereby improving the efficiency of determining the transmission path of the live stream.

[0045] In an embodiment of the present application, the live stream transmission device obtains a traceability identifier from the first live stream and records the traceability identifier, which also includes: when the live stream transmission device has a connection identifier acquisition request and a parent connection identifier acquisition request in the first live stream, the live stream transmission device obtains the first connection identifier of the live stream transmission device and the first parent connection identifier corresponding to the first connection identifier; writes the first connection identifier and the first parent connection identifier into the first live stream to obtain a third live stream.

[0046] It should be noted that the first live stream includes at least one second connection identifier and at least one second parent connection identifier corresponding to at least one first node.

[0047] In the embodiment of the present application, the first connection identifier can be a connection ID or session ID that identifies the first live stream in the CDN transit node (live stream transmission device), which is used to uniquely locate a connection session of the first live stream in a host (node). The first parent connection identifier is a connection identifier that identifies the parent node of the first live stream, and is mainly used to draw a topological trend diagram of the first live stream.

[0048] It should be noted that if live stream a is transmitted from host A (node) to host B (node), the connection identifier of host A will be adjusted to the parent connection identifier of host B, and the topology diagram will show that live stream a is transmitted from host A to host B.

[0049] It should be noted that if a live stream flows through two hosts, there will be a corresponding connection identifier at both ends of the two hosts.

[0050] Exemplarily, the connection identifier may be NodeId, and the AMF data type may be number. The parent connection identifier may be ParentNodeId, and the AMF data type may be number.

[0051] In an embodiment of the present application, the live stream transmission device transmits the first live stream to the stream pulling application end through at least one second node, and the live stream transmission device transmits the third live stream to the stream pulling application end through at least one second node.

[0052] It should be noted that the third live stream at the stream pulling application end includes at least one third connection identifier and at least one third parent connection identifier corresponding to at least one second node.

[0053] In an embodiment of the present application, the live streaming transmission device can also determine the first target second node that receives the first live streaming acquisition request transmitted by the streaming application end through at least one second node, determine the target third connection identifier of the target second node, and determine the first tracing identifier based on the target third connection identifier; and write the first tracing identifier into the first live streaming acquisition request to obtain a second request. The second request obtains the third live streaming from the CDN transit node in the CDN transit cluster that stores the third live streaming through any CDN secondary cache node in the CDN secondary cache cluster. The third live streaming is transmitted from the CDN transit node in the CDN transit cluster that stores the third live streaming to the streaming application end through any CDN secondary cache node in the CDN secondary cache cluster and any CDN viewing edge node in the CDN viewing edge cluster.

[0054] It should be noted that the target second node may be the first node among the at least one second node that receives the first live stream acquisition request. Specifically, the target second node is any node in the CDN viewing edge cluster.

[0055] It should be noted that the first connection identifier of the target second node may be an identifier of the connection relationship between the target second node and the stream pulling application end, that is, the connection relationship identifier of the right connection of the target second node.

[0056] Exemplarily, the first live stream acquisition request s' is transmitted from node A to node C via node B, and the right connection of node B is the connection relationship between node B and node C. Moreover, the connection relationship between node B and node C has one and only one connection identifier.

[0057] It should be noted that if the target second node generates a first tracing identifier when receiving a request to obtain the first live stream transmitted by the pull stream application end, and the first node among at least one first node generates a tracing identifier when receiving the first live stream transmitted by the push stream application end, then in the node (live stream transmission device) storing the first live stream in the CDN transit cluster, the first tracing identifier carried in the second request will be associated with the tracing identifier in the first live stream (i.e., a corresponding relationship between the first tracing identifier and the tracing identifier will be established). Or in the node storing the first live stream in the CDN secondary cache cluster, the first tracing identifier carried in the second request will be associated with the tracing identifier in the first live stream.

[0058] It should also be noted that the upstream trace id (traceability identifier) ​​and the downstream trace id (first traceability identifier) ​​are associated in the three stages of "RTMP Send Meta", "RTMP Send Audio Header" and "RTMP Send Video Header" of the Real Time Messaging Protocol (RTMP). Normally, only "RTMP Send Meta" needs to be matched, but there are also cases where some surveillance cameras do not send meta information when pushing streams. In this case, it is necessary to match "RTMP Send Audio Header" or "RTMP Send Video Header", that is, to associate the traceability identifier and the first traceability identifier in the "RTMP SendAudio Header" or "RTMP Send Video Header" stages.

[0059] In the embodiment of the present application, the live streaming transmission device also includes an RTMP module. The RTMP module is provided with various interaction stages of the RTMP protocol. In the RTMP protocol, the most suitable stage for introducing the trace id is the connect stage of NetConnction. The trace id and other information are added to the Command Object (AMF data), thereby passing the newly added trace id and other parameters to the server through the AMF sub-object. The RTMP protocol document describes the relevant information about the connect of NetConnction, such as Figure 3 As shown in the figure: If a trace id sub-object is added in the parsing of the AMF Connect phase, a sub-object with the same trace id is also added in the encapsulation of the RelaySend Connect phase. In this way, the relevant information about the trace id can be transmitted in each service, thereby realizing the trace tracking function.

[0060] In an embodiment of the present application, the live streaming transmission device also includes an RTMP module, and the RTMP module is provided with an HTTP protocol. The trace function of the HTTP protocol is mainly implemented through the header field of the http header, and servers at all levels transmit trace id information through the trace header field in the http header.

[0061] In an embodiment of the present application, the live stream transmission device writes the first connection identifier and the first parent connection identifier into the first live stream to obtain the third live stream. When the third live stream is transmitted to the first node of at least one second node, the first third connection identifier and the first third parent connection identifier are obtained in the first node of at least one second node according to the connection identifier acquisition request and the parent connection identifier acquisition request in the third live stream; and the first third connection identifier and the first third parent connection identifier are written into the third live stream until the third live stream flows through each node of at least one second node, and the corresponding at least one third connection identifier and at least one third parent connection identifier are obtained from each node, and the at least one third connection identifier and the at least one third parent connection identifier are written into the third live stream, and the third live stream is transmitted to the stream pulling application end.

[0062] It can be understood that since the first live stream carries a connection identifier acquisition request and a parent connection identifier acquisition request, the corresponding connection identifiers and parent connection identifiers of these nodes can be obtained from at least one first node transmitting the first live stream, a live stream transmission device, and at least one second node according to the connection identifier acquisition request and the parent connection identifier acquisition request, so that the third live stream flowing to the stream pulling application end carries at least one second connection identifier and at least one second parent connection identifier corresponding to at least one first node, a first connection identifier and a first parent connection identifier corresponding to the first connection identifier, at least one third connection identifier and at least one third parent connection identifier corresponding to at least one second node, so that the transmission path of the first live stream can be quickly determined according to multiple connection identifiers (at least one second connection identifier, a first connection identifier, and at least one third connection identifier) ​​and multiple parent connection identifiers (at least one second parent connection identifier, a first parent connection identifier, and at least one third parent connection identifier) ​​in the third live stream, thereby improving the efficiency of determining the live stream transmission path.

[0063] In the embodiment of the present application, the traceability identifier is a traceability identifier generated by using a preset traceability identifier generation strategy to generate a unique traceability identifier corresponding to the first live stream.

[0064] In an embodiment of the present application, the preset traceability identification generation strategy may be a strategy that can be configured in the live streaming transmission device; the preset traceability identification generation strategy may also be a strategy transmitted from other devices to the live streaming transmission device; the specific way in which the live streaming transmission device obtains the preset traceability identification generation strategy may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0065] It should be noted that the preset traceability identification generation strategy can be a strategy for generating traceability identification in the prior art; the preset traceability identification generation strategy can also be a strategy for generating traceability identification that does not exist in the prior art and is configured for the live streaming transmission device; the specific preset traceability identification generation strategy can be determined according to actual conditions, and the embodiments of the present application are not limited to this.

[0066] Exemplarily, the preset traceability identifier generation strategy may be a TraceId generation strategy.

[0067] In an embodiment of the present application, when the first node among at least one first node receives the second live stream transmitted by the streaming application end, it directly uses the preset traceability identifier generation strategy to generate a traceability identifier that uniquely identifies the second live stream, and then adds the traceability identifier to the second live stream to obtain the first live stream. Alternatively, when the first node among at least one first node receives the second live stream transmitted by the streaming application end, it obtains the target connection identifier of the first node, and uses the target connection identifier as the traceability identifier, and then adds the traceability identifier to the second live stream to obtain the first live stream. Wherein, before receiving the first live stream, if other traceability identifiers have been determined based on the target connection identifier of the first node, it is considered that the target connection identifier is unavailable, and the target connection identifier is no longer used to determine the traceability identifier; the preset traceability identifier generation strategy can be used to generate a traceability identifier that uniquely identifies the second live stream, and then the traceability identifier is added to the second live stream to obtain the first live stream.

[0068] In an embodiment of the present application, the target second node can also generate a first tracing identifier that uniquely identifies the first live stream acquisition request by using a preset tracing identifier generation strategy when receiving the first live stream acquisition request transmitted by the stream pulling application end; and write the first tracing identifier into the first live stream acquisition request to obtain a second request. The second request obtains the third live stream from the node storing the third live stream in the CDN transit cluster through any node in the CDN secondary cache cluster. The third live stream is transmitted from the node storing the third live stream in the CDN transit cluster to the stream pulling application end through any node in the CDN secondary cache cluster.

[0069] It can be understood that a preset traceability identifier generation strategy is used to generate a traceability identifier that uniquely identifies the first live stream, and the first live stream is identified by using the unique traceability identifier, so that the nodes through which the first live stream passes can be traced throughout according to the traceability identifier, that is, the nodes through which the first live stream passes can be determined, so that the transmission path of the first live stream can be quickly determined according to the nodes through which the first live stream passes, thereby improving the efficiency of determining the transmission path of the live stream.

[0070] In an embodiment of the present application, when the first node among at least one first node receives an instruction to track and sample the second live stream, it adds a sampling identifier to the second live stream, where the identifier value of the sampling identifier is a first preset value, and then adds a tracing identifier to the information header of the second live stream to obtain the first live stream.

[0071] In the embodiment of the present application, before adding the sampling identifier to the second live stream, the first node of the at least one first node also obtains the sampling identifier.

[0072] In an embodiment of the present application, the sampling identifier may be an identifier configured in the first node of at least one first node; the sampling identifier may also be an identifier received before receiving an instruction to track and sample the first live stream; the specific manner in which the first node of at least one first node obtains the sampling identifier may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0073] In the embodiment of the present application, the sampling identifier may be an identifier in the form of characters; the sampling identifier may also be an identifier in the form of numbers; the sampling identifier may also be an identifier in other forms; the specific sampling identifier is determined according to actual conditions, and the embodiment of the present application does not limit this.

[0074] Exemplarily, the sampling flag may be Sampled, and the AMF data type may be Boolean.

[0075] In an embodiment of the present application, the second live stream may also be a live stream configured with a sampling identifier. The first node of at least one first node adds a tracing identifier in the second live stream to obtain the first live stream. The process may also be that upon receiving an instruction to track and sample the second live stream, the identification value of the sampling identifier in the second live stream is set to a first preset value; and then the tracing identifier is added to the second live stream to obtain the first live stream.

[0076] It should be noted that the first preset value is 1.

[0077] It should also be noted that before the live streaming transmission device adjusts the identification value of the sampling identification to the first preset value, the identification value of the sampling identification is 1.

[0078] In an embodiment of the present application, when the first node among at least one first node receives an instruction to debug the second live stream, it adds a debugging identifier to the second live stream, sets the identifier value of the debugging identifier in the second live stream to a first preset value, and then adds a tracing identifier to the second live stream information header to obtain the first live stream.

[0079] In an embodiment of the present application, the live stream transmission device adds a debugging identifier to the second live stream, and the live stream transmission device also obtains the debugging identifier.

[0080] In an embodiment of the present application, the debugging identifier may be an identifier configured in the first node of at least one first node; the debugging identifier may also be an identifier transmitted by other devices to the first node of at least one first node; the specific manner in which the first node of at least one first node obtains the debugging identifier may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0081] In the embodiments of the present application, the debugging identifier can be an identifier in character form; the debugging identifier can also be an identifier in digital form; the debugging identifier can also be an identifier in other forms; the specific debugging identifier is determined based on actual conditions, and the embodiments of the present application do not limit this.

[0082] Exemplarily, the debugging flag may be Flags, and the AMF data type is Boolean.

[0083] In an embodiment of the present application, the second live stream may also be a live stream configured with a debugging identifier. The first node of at least one first node adds a tracing identifier in the second live stream to obtain the first live stream. The process may also be that when a debugging instruction for the second live stream is received, the identifier value of the debugging identifier in the second live stream is set to a first preset value, and then a tracing identifier is added to the second live stream to obtain the first live stream.

[0084] It should be noted that, before the live streaming transmission device adjusts the identification value of the debugging identification to the first preset value, the identification value of the debugging identification is 0.

[0085] In the embodiment of the present application, the process in which the live stream transmission device adds a tracing mark in the second live stream to obtain the first live stream can also be: when the live stream transmission device receives a tracking sampling instruction for the second live stream and a debugging instruction for the second live stream, the sampling mark is added to the second live stream to obtain the first updated live stream; and the tracing mark and the debugging mark are added to the first updated live stream to obtain the first live stream. It can also be that when the live stream transmission device receives a tracking sampling instruction for the second live stream and a debugging instruction for the second live stream, the debugging mark is added to the first live stream to obtain the second updated live stream; and the sampling mark and the tracing mark are added to the second updated live stream to obtain the first live stream. The specific process can be determined according to the actual situation, and the embodiment of the present application does not limit this.

[0086] S102: Obtain a traceability identifier from the first live stream, and record the traceability identifier.

[0087] In an embodiment of the present application, after the live stream transmission device obtains the first live stream transmitted by the streaming application terminal through at least one first node, the live stream transmission device can obtain a traceability identifier from the first live stream and record the traceability identifier.

[0088] In an embodiment of the present application, the live streaming transmission device may record the traceability identifier in a memory, or the live streaming transmission device may record the traceability identifier in a disk. The specific location where the live streaming transmission device records the traceability identifier may be determined based on actual conditions, and the embodiment of the present application does not limit this.

[0089] S103: upon receiving a request for obtaining a first live stream transmitted by a stream pulling application terminal through at least one second node, transmitting the first live stream to the stream pulling application terminal through at least one second node; the traceability identifier is also used to identify at least one second node through which the first live stream flows.

[0090] In an embodiment of the present application, after the live stream transmission device records the traceability identifier, upon receiving a first live stream acquisition request transmitted by the stream pulling application end through at least one second node, the live stream transmission device transmits the first live stream to the stream pulling application end through at least one second node.

[0091] In an embodiment of the present application, based on a method of determining a transmission path of the first live stream according to at least one first node, a live stream transmission device, and at least one second node, the transmission path of the first live stream can be drawn for the live stream transmission device according to a node cluster to which at least one first node, the live stream transmission device, and at least one second node belong.

[0092] It can be understood that when the first live stream flows through at least one first node, a live stream transmission device and at least one second node, by writing the traceability identifier carried in the first live stream into at least one first node, the live stream transmission device and at least one second node, that is, using the traceability identifier to mark the nodes passed by when the first live stream is transmitted from the push application end to the pull application end, when tracing the first live stream, the node transmitting the first live stream can be quickly determined directly according to the traceability identifier in the node, so as to quickly determine the transmission path of the first live stream according to the node transmitting the first live stream, that is, the efficiency of determining the live stream transmission path is improved.

[0093] Based on the same inventive concept as the above-mentioned live streaming transmission method, the embodiment of the present application provides a live streaming transmission device 1, corresponding to a live streaming transmission method; Figure 4 A schematic diagram of the structure of a live streaming transmission device provided in an embodiment of the present application Figure 1 , the live streaming transmission device 1 may include:
