[0029] Exemplary embodiments of the disclosure are described herein with reference to the accompanying drawings, which are included to provide a thorough understanding of embodiments of the disclosure by a person of ordinary skill in the art, and should be considered in conjunction with the Disclosure. It will be appreciated that those skilled in the art will be able to devise various arrangements that, although not explicitly described or shown herein, embody the principles of the disclosure, and thus, within the scope of the disclosure. In addition, for clarity and conciseness, descriptions of well-known functions and constructions are omitted from the following description.

[0030] Obviously, the described embodiments are part of the embodiments of the disclosure, rather than all the embodiments. Based on the embodiments in the disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor are within the scope of protection of the disclosure.

[0031] It should be noted that the terminal device involved in the embodiments of the disclosure can include, but is not limited to, a mobile phone, a personal digital assistant (PDA), a wireless handheld device, a tablet computer, and the like. The display device can include, but is not limited to, a personal computer, a television, and the like.

[0032] In addition, the term "and / or" in this paper is only to describe the association relationship between the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B, and the existence of B alone. In addition, the character " / " in this paper generally represents an "or" relationship between the associated objects before and after it.

[0033] Figure 1 is a live broadcast architecture schematic diagram provided by an embodiment of the disclosure, as shown in Figure 1 In the live broadcast architecture, at least one layer of node layer can be arranged between the client layer and the streaming media center platform. The client layer includes a host client and a viewer client. In order to more clearly show the live broadcast architecture, Figure 1 arranged between the client layer and the streaming media center platform, for example, the edge node layer in which the push stream edge node and the pull stream edge node are located, and the upper node layer in which the upper node is located. The upper node layer is the nearest neighbor layer below the streaming media center platform. The nodes in the same layer in this embodiment can also be referred to as nodes at the same level, that is, nodes at the same level in the live broadcast architecture.

[0034] As shown in Figure 1 , the upper node layer where the upper node 1, the upper node 2, and the upper node 3 are located is the nearest node layer to the live streaming center platform. In an actual application scenario, there can be at least one intermediate node layer between the edge node layer where the push stream edge node is located and the upper node layer where the upper node 1 is located, or there can be no intermediate node layer. Figure 1 In the architecture shown in , the push stream edge node, the pull stream edge node, the nodes in the intermediate layer, and the upper node are implemented by using a content delivery network (CDN) node.

[0035] Moreover, in an actual application, the edge node layer and the upper node layer can be the same layer. At this time, as shown in Figure 2 , a live streaming architecture diagram is obtained, and as shown in Figure 2 , at this time, the live streaming architecture can only include three layers, such as a client layer, an edge node layer, and a live streaming center platform. At this time, the push stream edge node and the pull stream edge node are the nearest node layer to the live streaming center platform, that is, in the live streaming architecture, the edge node layer is also the upper node layer.

[0036] In the architecture shown in Figure 1 , during live streaming, the anchor uploads a live stream to the nearest push stream edge node through an anchor client, and then the push stream edge node pushes the live stream to the upper node 1 through the nodes in the intermediate layer, and the upper node 1 pushes the live stream to the live streaming center platform.

[0037] On the audience side, taking two audiences requesting to watch the live stream of the same anchor as an example, for example, the audience client 1 initiates a source request to the nearest pull stream edge node 1 to pull the live stream of the live broadcast. If there is no resource of the live stream in the pull stream edge node 1, the source request is continuously requested to the upper node, until the source request is sent to the upper node 2, the upper node 2 pulls the live stream of the anchor from the live streaming center platform, and then transmits it back to the pull stream edge node 1. Similarly, the audience client 2 initiates a source request to the nearest pull stream edge node 2 to pull the live stream of the live broadcast. If there is no resource of the live stream in the pull stream edge node 2, the source request is continuously requested to the upper node, until the source request is sent to the upper node 3, the upper node 3 pulls the live stream of the anchor from the live streaming center platform, and then transmits it back to the pull stream edge node 1.

[0038] Figure 1 In the architecture shown in Figure 1For each audience's back-to-source request, the architecture shown finally pulls the live stream from the streaming center platform by the corresponding upper layer node. Even for the same live stream, the streaming resource needs to transmit many times to multiple upper layer nodes of the next layer, resulting in a very large bandwidth consumption of the streaming platform.

[0039] Figure 3 is a schematic diagram according to the first embodiment of the present disclosure; as Figure 3 shown, the embodiment provides a back-to-source processing method, which is specifically applied in the upper layer node of the next layer of the streaming center platform, for example, can be applied in any upper layer node in the upper layer node layer of the next layer of the streaming center platform in Figure 1 or Figure 2 . The back-to-source processing method of the embodiment can specifically include the following steps:

[0040] S301, based on the first live stream identifier in the received first back-to-source request, determining the information of the target upper layer node in the current upper layer node layer responsible for processing the back-to-source of the first live stream;

[0041] S302, based on the information of the target upper layer node, forwarding the first back-to-source request to the target upper layer node to obtain the first live stream corresponding to the first live stream identifier from the target upper layer node.

[0042] In the embodiment, a certain technical means can be used to configure a corresponding target upper layer node for each live stream identifier in the upper layer node layer. For example, based on the first live stream identifier, the information of the target upper layer node in the upper layer node layer responsible for processing the back-to-source of the first live stream can be determined; and then based on the information of the target upper layer node layer, the first back-to-source request can be forwarded to the target upper layer node to obtain the first live stream corresponding to the first live stream identifier from the target upper layer node, so that the back-to-source in the same layer node is realized, and the back-to-source of all nodes to the streaming center platform is avoided, thereby causing the excessive consumption of the bandwidth resources of the streaming center platform.

[0043] The back-to-source processing method of the embodiment can realize the back-to-source in the same layer node by using the above-mentioned manner, which can effectively avoid the back-to-source of all nodes to the streaming center platform, and thereby can effectively reduce the cost of the bandwidth resources of the streaming center platform.

[0044] Figure 4 is a schematic diagram according to the second embodiment of the present disclosure; the embodiment provides a back-to-source processing method, which is based on the technical solution of the above-mentioned Figure 3 embodiment, and further describes the technical solution of the present disclosure in more detail. As Figure 4 shown, the back-to-source processing method of the embodiment can specifically include the following steps:

[0045] S401, the current upper node receives the first live stream identifier in the first source return request;

[0046] S402, the current upper node performs a consistent hash calculation based on the first live stream identifier to determine the identifier of the target upper node responsible for processing the first live stream source return in the upper node layer where the current upper node is located;

[0047] For example, the first live stream identifier is identified by a string of numbers. If the upper node layer where the current upper node is located includes M upper nodes. The algorithm used in the consistent hash calculation can be to divide the first live stream identifier by M to obtain the corresponding remainder. Based on the remainder, the first live stream identifier is allocated to the identifier of the target upper node responsible for processing the first live stream source return. The remainders 0 to M-1 correspond to M upper nodes, and each remainder corresponds to an upper node. In this way, the identifier of the target upper node responsible for processing the first live stream source return can be determined very accurately and efficiently.

[0048] S403, the current upper node detects whether the target upper node is the current upper node itself; if not, step S404 is performed; if yes, step S405 is performed;

[0049] S404, the current upper node forwards the first source return request to the target upper node based on the identifier of the target upper node to obtain the first live stream corresponding to the first live stream identifier from the target upper node, and ends.

[0050] For example, the address information of the target upper node can be obtained according to the identifier of the target upper node, and then the first source return request is forwarded to the target upper node based on the address information of the target upper node. For example, in the live architecture, the address information of each node in each layer of the architecture can be configured, which can be directly obtained.

[0051] S405, the current upper node forwards the first source return request to the streaming media center platform to obtain the first live stream corresponding to the first live stream identifier from the streaming media center platform, and ends.

[0052] In this embodiment, the source return processing method is introduced in the granularity of nodes.

[0053] The source return processing method of this embodiment can realize source return in the nodes in the same layer, which can effectively avoid all nodes returning to the streaming media center platform, and thus can effectively reduce the cost of bandwidth resources of the streaming media center platform.

[0054] Figure 5 is a schematic diagram according to the third embodiment of the present disclosure; the present embodiment provides a source return processing method, which is based on the above Figure 3 or Figure 4The technical solutions of the embodiments are described in detail based on the technical solutions of the embodiments. Figure 5 As shown, the source return processing method of the embodiments can specifically include the following steps:

[0055] S501, control the current service process receiving the first source return request to determine the identifier of the target service process responsible for processing the first live stream source return in the current upper layer node based on the first live stream identifier;

[0056] Different from the above Figure 3 The embodiments differ from the above

[0057] Specifically, in the embodiments, the current service process in the current upper layer node receives the first source return request as an example.

[0058] Specifically, in the embodiments, the current service process in the current upper layer node receives the first source return request as an example.

[0059] For example, the first live stream identifier of the embodiments can be identified by a string of numbers. Assuming that the number of service processes in the current upper layer node is n, the algorithm used for consistency hash calculation can be to divide the first live stream identifier by n to obtain the corresponding remainder. Based on the remainder, the target service process responsible for processing the first live stream source return is allocated an identifier. The remainders 0 to n-1 correspond to n service processes, and each remainder corresponds to a service process. In this way, the identifier of the target service process responsible for processing the first live stream source return can be accurately and efficiently determined.

[0060] S502, control the current service process to detect whether the target service process is itself based on the identifier of the target service process; if not, perform step S503; if yes, perform step S508;

[0061] S503, control the current service process to forward the first source return request to the target service process based on the identifier of the target service process; perform step S504;

[0062] S504, control the target service process to determine the identifier of the target upper layer node responsible for processing the first live stream source return in the current upper layer node based on the first live stream identifier; perform step S505;

[0063] Specifically, the above step S402 can be used to achieve this. In this way, the identifier of the target upper layer node responsible for processing the first live stream source return can be accurately and efficiently determined.

[0064] S505, forwarding, by the target service process, the first source returning request to the target upper node based on the identifier of the target upper node, to obtain the first live stream corresponding to the first live stream identifier from the target upper node;

[0065] S506, establishing an auxiliary channel between the target service process and the current service process; and performing step S507;

[0066] S507, controlling the target service process to return the forwarding information of the first source returning request to the current service process through the auxiliary channel, the forwarding information carrying the information of the target upper node; and performing step S510;

[0067] That is, through the auxiliary channel, the target service process can inform the current service process that the first source returning request currently requested by the current service process is sent to the target upper node in the same layer by the target service process, and the target upper node is responsible for processing the source returning of the first live stream of the first source returning request.

[0068] S508, controlling the current service process to determine the identifier of the target upper node responsible for processing the source returning of the first live stream in the upper node layer where the current service process is located based on the first live stream identifier; and performing step S509;

[0069] Specifically, the above step S402 can be used to achieve this. According to this method, the identifier of the target upper node responsible for processing the source returning of the first live stream can be accurately and efficiently determined.

[0070] S509, controlling the current service process to forward the first source returning request to the target upper node based on the identifier of the target upper node, to obtain the first live stream corresponding to the first live stream identifier from the target upper node; and ending.

[0071] In the embodiment, after the current service process forwards the first source returning request to the target upper node, the process in the current upper node ends, but the entire source returning process does not end. In the target upper node, the target upper node is taken as the current upper node to execute the technical solution of the embodiment, so that accurate source returning can be ensured.

[0072] For the current service process of the current upper node, after the first source returning request is forwarded, the subsequent waiting for the target upper node to return the streaming media resource of the first live stream based on the first source returning request can be performed.

[0073] S510, if the current service process receives a second source return request carrying the second live stream identifier and the information of the sending end, the current service process is controlled to detect whether the second live stream identifier is the first live stream identifier being requested; if yes, step S511 is executed; if no, step S501 is returned; the second source return request is processed according to the processing mode of the above-mentioned first source return request; that is, the first source return request is replaced by the second source return request, and the processing is continued.

[0074] Specifically, detecting whether the second live stream identifier is the first live stream identifier being requested is equivalent to detecting whether the second live stream identifier in the received second source return request is same as the first live stream identifier in the first source return request being requested.

[0075] In this step, the current service process is taken as an example of requesting the first live stream, and in actual application, the current service process needs to detect whether the currently received second source return request is same as each source return request being requested.

[0076] S511, the current service process is controlled to detect whether the sending end of the second source return request is the target upper node to which the first source return request corresponding to the first live stream identifier being requested is forwarded; if yes, step S512 is executed; if no, the process is ended.

[0077] If the current service process detects that the second live stream identifier is the first live stream identifier being requested, but the sending end of the second source return request is not the target upper node to which the first source return request corresponding to the first live stream identifier being requested is forwarded, it can be determined that the closed loop does not occur. Only it can be indicated that the other upper node sends the first source return request to the current service process of the current upper node. Since the current service process has forwarded the first source return request, it is not necessary to repeat the processing at this time, and the first live stream corresponding to the first source return request being requested can be obtained.

[0078] S512, the current service process is controlled to return a source return message to the sending end, the source return message being used to indicate the message for the sending end to request the first live stream from the streaming media center platform; step S513 is executed.

[0079] S513, the current service process is controlled to disconnect the connection with the sending end, and the process is ended.

[0080] If the current service process detects that the second live stream identifier is the first live stream identifier being requested, and the sending end of the second source return request is the target upper node to which the first source return request corresponding to the first live stream identifier being requested is forwarded, it can be determined that the closed loop occurs. Therefore, the sending end needs to be informed to request the first live stream from the streaming media center platform, and the connection between the current service process and the sending end is disconnected, which can effectively ensure the accurate execution of the source return.

[0081] By adopting the steps S510-S513, the situation that a closed loop is generated in the source returning process and the live stream cannot be acquired can be prevented, and the accurate execution of the source returning can be effectively ensured, and the normal progress of the live service is ensured.

[0082] It should be noted that in actual application, the same layer nodes in the live architecture are not always fixed. For example, for the upper layer nodes, some of the upper layer nodes can be faulty in use. For example, for the same live stream identifier, when the consistent hash calculation is performed, the number of the upper layer nodes participating in the calculation is different, the target upper layer node determined to process the source returning of the live stream can also be different, and thus the source returning closed loop as described above can be caused.

[0083] In the embodiment, the source returning processing method is described by taking the current process as an example. In actual application, the current process can be any process in any upper layer node of the upper layer nodes. That is, each process in each upper layer node needs to perform detection according to the scheme of the embodiment, which can effectively avoid the closed loop in the source returning of the nodes in the same layer, and cannot acquire the live stream, and can ensure the acquisition of the live stream and the progress of the live service. Figure 5 The scheme of the embodiment can effectively avoid the closed loop in the source returning of the nodes in the same layer, and cannot acquire the live stream, and can ensure the acquisition of the live stream and the progress of the live service.

[0084] The source returning processing method of the embodiment can achieve the source returning processing by taking the process in the upper layer node as a granularity, which can not only achieve the source returning of the nodes in the same layer, and can effectively avoid the source returning of all the nodes to the streaming media center platform, and can effectively reduce the cost of the bandwidth resources of the streaming media center platform. Moreover, the technical scheme of the embodiment can effectively avoid the source returning closed loop and the situation that the live stream cannot be acquired, and can ensure the acquisition of the live stream and the progress of the live service.

[0085] Figure 6 is a schematic view according to the fourth embodiment of the present disclosure; as Figure 6 is shown, CDN node A and CDN node B in the next layer of the streaming media center platform are taken as examples, and the node layer in the next layer of the streaming media center platform also includes other CDN nodes, which are not shown in the figure.

[0086] As Figure 6 shown, the service process 1 of the CDN node A can receive the source returning request of the client, and the source returning request carries the identifier of the live stream, which is used to request the source returning of the live stream. As the client client1 sends the source returning request to the service process 1 through the link 1. Based on the identifier of the live stream, the service process 1 performs the detection according to the scheme of the embodiment, and the service process 1 can determine the target upper layer node to process the source returning of the live stream. Figure 5The consistent hash calculation of the illustrated embodiment can control the service process to detect and determine that the service process 2 in the CDN node A is responsible for processing the live stream source, so the service process 1 can be controlled to forward the source request to the service process 2. As shown in Figure 6 The service process 1 forwards the source request to the service process 2 through the link 2. The service process 2 can be controlled to determine that the CDN node B in the same layer is responsible for the live stream source according to Figure 5 The scheme of the illustrated embodiment detects and determines that the CDN node B in the same layer is responsible for the live stream source. Therefore, the service process 2 can be controlled to forward the source request to the service process 3 of the CDN node B, for example, through the link 5. Similarly, in the CDN node B, the service process 3 can also be controlled to detect and determine that the service process 4 in the CDN node B processes the live stream source. Therefore, the service process 3 can be controlled to forward the source request to the service process 4 through the link 6.

[0087] The service process 4 can also be controlled to use the consistent hash calculation, but since the service process 2 of the CDN node A and the service process 4 of the CDN node B perform the consistent hash calculation at different times, when the service process 4 performs the consistent hash calculation, a part of the CDN nodes in the same layer may fail, causing the service process 4 to determine that the CDN node A is responsible for the live stream source in the CDN node layer in the same layer. Therefore, the service process 4 can be controlled to forward the source request to the CDN node A again, for example, through the link 7 to the service process 1. In addition, in the CDN node B, the service process 3 also receives the source request of the same live stream identifier of the client 2 through the link 3. Similarly, the service process 5 can be controlled to perform the consistent hash calculation and determine that the service process 4 processes the live stream source. The service process 4 is forwarded through the link 4.

[0088] At this time, since the service process 1 has learned through the auxiliary channel between the service process 1 and the service process 2 that the source request is forwarded to the CDN node B, and the source request from the CDN node B is received again, it can be determined that a source loop occurs. At this time, the service process 1 can return the source message to the service process 4 of the CDN node B to instruct the service process 4 of the CDN node B to request the source from the streaming media center platform and disconnect the link 7.

[0089] The technical scheme of the embodiment not only can realize the source between the CDN nodes in the same layer to reduce the bandwidth cost of the streaming media center, but also can prevent the source between the CDN nodes in the same layer from forming a loop to cause the resource to be unable to be obtained, and can effectively ensure the normal operation of the live broadcast service.
