Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, device, computer-readable medium, and computer program product for processing live streaming data. Background Art

[0002] Based on the existing technology of Content Delivery Network (CDN) network solutions applied to live broadcast scenarios, massive multimedia content needs to be distributed from the storage system to the user terminal. In order to shorten the distance to the user end and improve the user experience, it is necessary to deploy CDN networks as far as possible across the country or even globally to achieve the purpose of covering users nearby. Generally, a single CDN node is small in scale and has limited storage and computing power. Therefore, the platform will deploy multiple large-capacity regional caching CDN nodes across the country to provide service capabilities. After the live stream is pushed to the nearest node, the transcoding service generates a transcoded stream by pulling the stream through the public network. The production of multiple transcoded streams is to provide users with more bandwidth options and ensure that users with different network speeds can have a smooth viewing experience.

[0003] However, the public network return method is costly. Summary of the Invention

[0031] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Memory may include non-permanent storage in a computer-readable medium, in the form of random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM. Memory is an example of a computer-readable medium.

[0034] Computer-readable media include both permanent and non-permanent, removable and non-removable media, and can be implemented by any method or technology for information storage. Information can be computer program instructions, data structures, program modules, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technology, compact disc-read only memory (CD-ROM), digital versatile disc (DVD) or other optical storage, magnetic cassettes, magnetic tape, disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device.

[0035] The following describes the terms involved in the embodiments of the present application.

[0036] Live streaming: A data stream that transmits audio and video content in real time. It is real-time and interactive. The live streaming process is a long link. Unless the host actively interrupts the stream, the live streaming will continue.

[0037] Live Edge Computing: A technology that pushes live stream processing and distribution to the edge of the network. It combines edge computing and live streaming to improve the live streaming experience and reduce the impact of latency and network congestion.

[0038] IDC: Internet Data Center (IDC) can provide users with services including domain name application, virtual host space rental, host hosting, etc.

[0039] Edge computing nodes are an important part of the edge computing architecture. They are located at the edge of the network and are used to perform computing tasks, process data, and provide services.

[0040] Back-to-origin: Back-to-origin refers to the process in which CDN nodes fetch data from the origin server and return it to the viewing user.

[0041] Figure 1 The flowchart of a method provided in an embodiment of the present application is shown. The method at least includes step S101, step S102 and step S103.

[0042] In the live broadcast scenario, the method according to this embodiment can be executed by a server for scheduling live broadcast streams. The server pushes the live broadcast stream pushed to the edge node to the entry device of the established dedicated content distribution network, thereby entering the dedicated content distribution network through the entry device to pull the stream, and transcoding the live broadcast stream after pulling the stream, so that the CDN-related inter-access service bandwidth is switched from the public network to the intranet.

[0043] The method of the embodiment of the present application is applied to a dedicated content delivery network, wherein the dedicated content delivery network is a dedicated network composed of multiple CDN nodes, multiple metropolitan area network nodes, multiple backbone network nodes, multiple source station IDCs, and multiple POP nodes.

[0044] Among them, CDN is composed of computer room nodes that can be spread across various regions and communication operators' networks around the world. CDN service providers deploy related software and hardware based on these computer room nodes to form a network. The computer room nodes that make up this network are usually called Point of Presence (POP) nodes at the edge of CDN.

[0045] Among them, the multiple CDN nodes are respectively connected to the corresponding metropolitan area network nodes nearby through single regulation or dual regulation; the multiple metropolitan area network nodes are respectively connected to the corresponding backbone network nodes nearby through single regulation or dual regulation; the multiple backbone network nodes are respectively connected to the corresponding POP nodes of the video website nearby, and connect the CDN and the source station network through the POP nodes.

[0046] Refer to the following Figure 2 The architecture of the dedicated content delivery network in the embodiment of the present application is described below.

[0047] Figure 2 A schematic diagram of the architecture of an exemplary dedicated content delivery network according to an embodiment of the present application is shown.

[0048] Reference Figure 2 This architecture includes a dedicated content distribution network (CDN) consisting of multiple secondary data centers serving video websites, a transcoding center in Changshu, and data centers of several smaller operators, all connected by dedicated lines. This dedicated CDN switches the bandwidth for CDN-related interoperability services from the public network to the intranet.

[0049] Specifically, refer to Figure 2 This exemplary dedicated content delivery network includes multiple CDN nodes, multiple metropolitan area network nodes, multiple backbone network nodes, multiple origin IDCs, and multiple POP nodes. These nodes form a five-level ring-shaped dedicated content delivery network from the outside to the inside.

[0050] Each CDN node is connected to the nearest metropolitan area network node through a single or dual-channel approach. This access method prioritizes back-to-source routing through the dedicated content distribution network (CDN), while public network back-to-source routing serves as a fallback strategy.

[0051] Among them, each metropolitan area network node is connected to the corresponding backbone network node nearby through single-regulation or dual-regulation.

[0052] Among them, each backbone network node is connected to the corresponding POP node of the video website nearby, and connects the CDN and source station network through the POP node.

[0053] Each source IDC deploys two forwarding devices as the entry point to the dedicated content delivery network. These two devices serve as a primary and a backup, and each device provides one private IP address and one public IP address, serving as the private and public streaming addresses, respectively.

[0054] Reference Figure 1 To illustrate, in step S101, in response to a node receiving a live stream push, service-related information corresponding to the node is obtained.

[0055] The service information includes operator information and uplink server type information. The operator information includes various information that can be used to indicate the operator name, such as China Telecom or China Mobile.

[0056] Optionally, the operator information further includes information indicating a geographical location, for example, East China Telecom.

[0057] The method can classify servers according to usage, chassis structure, processing architecture, and other methods, and set corresponding type information.

[0058] Optionally, the uplink server type information may include a public cloud 3-line server (BGP server), a single-line server in a company's self-built computer room, and an edge node server of a third-party cloud vendor.

[0059] In step S102, the live stream is forwarded to an ingress device of a dedicated content delivery network that matches the service-related information, thereby entering the dedicated content delivery network via the ingress device.

[0060] The entry device is a forwarding device deployed at the source station IDC of a dedicated content delivery network.

[0061] Optionally, the method determines a matching entry device based on geographic location information. Specifically, the service-related information includes the geographic location information of the node, and the method uses an entry device in the area of ​​the node's geographic location information as the entry device of the dedicated content delivery network that matches the service-related information.

[0062] According to one embodiment, if the live stream is received by a third-party edge node, the live stream is forwarded to the entry device of the matching dedicated content distribution network through the public network; if the live stream is received by a self-built edge node, the live stream is forwarded to the entry device of the matching dedicated content distribution network through the intranet.

[0063] In step S103, the live stream is pulled through a dedicated content distribution network, and the pulled live stream is transcoded.

[0064] According to one embodiment, the portal device provides an intranet IP address and a public IP address, which serve as the intranet streaming address and the public IP address, respectively. In step S103, the method pulls the live stream via a dedicated content delivery network (CDN) based on the intranet streaming address provided by the portal device. If pulling the live stream via the dedicated CDN fails, pulling the live stream via the public network is performed based on the public IP address.

[0065] According to one embodiment, the method further includes step S104, step S105 and step S106.

[0066] In step S104, the popularity type information of the live stream is obtained.

[0067] The popularity type information is obtained by classifying each live stream based on the popularity of the live stream.

[0068] For example, based on the predetermined number of historical live broadcast viewers, the live stream can be divided into four types or levels: cold stream, hot stream, warm stream and extremely cold stream.

[0069] In step S105 , a corresponding back-to-source strategy is acquired based on the popularity type information, where the back-to-source strategy includes corresponding back-to-source access paths.

[0070] The back-to-source strategy is to back-source popular live streams through the established dedicated content distribution network, and to back-source less popular live streams through the public network.

[0071] In step S106, the live stream is processed back to the source according to the back to source access path in the back to source policy.

[0072] For example, refer to Figure 3The architecture shown in the figure uses a three-layer structure (L1, L2, and L3) from bottom to top to process access requests from user terminals back to the source. L1 corresponds to the self-built edge node (represented by the self-built CDN edge L1), L2 corresponds to the dedicated content delivery network (represented by the B2-CDN network), and L3 corresponds to the public network back to the source origin and the public network back to the source EC.

[0073] The B2-CDN network has a ring structure, including multiple metropolitan area network nodes, backbone network nodes, source station IDC and POP nodes corresponding to different geographical locations. Figure 3 The POPs shown include those corresponding to different provinces (denoted as POPs in Provinces A through E). At each POP, backbone network nodes corresponding to different cities in that province connect to the nearest POP. Backbone network nodes of different colors correspond to different carriers.

[0074] This example categorizes live streams requested by users into four different levels of popularity: cold streams, hot streams, warm streams, and extremely cold streams.

[0075] Reference Figure 3 The forwarding path diagram shown in the figure shows the corresponding back-to-origin strategies for live streams with four different heat levels: cold stream, hot stream, warm stream, and extremely cold stream:

[0076] 1) For cold streams, the live stream is pushed to a geographically matching L2 node in the L2 layer, and then back-sourced via the public network L2. Back-sourced via the public network L2 refers to a stream at a certain L2 node. If a user accesses this stream at an edge node below another L2 node, the stream is retrieved via the L2 public network back-source and provided to the downstream edge node.

[0077] 2) For hot traffic, the live stream is pushed to the self-built edge node at the L1 layer. The self-built edge node at the L1 layer then pushes the stream to the corresponding node in the B2-CDN network at the L2 layer, and then back to the source through the public network L2.

[0078] 3) For the warm stream, the live stream is pushed to the self-built edge node in the L1 layer. The self-built edge node in the L1 layer then pushes the stream to the corresponding node in the B2-CDN network in the L2 layer, and then back to the source through the public network L2.

[0079] 4) For extremely cold streams, push the live stream to the public network back-to-source EC for public network back-to-source.

[0080] According to the method of the embodiment of the present application, a dedicated content distribution network consisting of multiple CDN nodes, multiple metropolitan area network nodes, multiple backbone network nodes, multiple source station IDCs and multiple POP nodes is constructed, and the live stream pushed to the edge node is pushed to the entrance device of the constructed dedicated content distribution network, thereby entering the dedicated content distribution network through the entrance device to pull the stream, and transcoding the live stream after pulling the stream, so that the CDN-related inter-access service bandwidth is switched from the public network to the intranet, reducing costs.

[0081] In addition, the embodiment of the present application also provides a device for processing live streaming data, the structure of the device is as follows: Figure 4 shown.

[0082] The device includes: a device for obtaining service-related information corresponding to a node in response to a node receiving a live stream push (hereinafter referred to as "information acquisition device 101"), a device for forwarding the live stream to an entry device of a dedicated content distribution network that matches the service-related information, thereby entering the dedicated content distribution network through the entry device (hereinafter referred to as "stream push forwarding device 102"), and a device for pulling the live stream through the dedicated content distribution network, thereby transcoding the pulled live stream (hereinafter referred to as "stream pulling processing device 103").

[0083] In the live broadcast scenario, the device according to this embodiment is included in a server for scheduling live broadcast streams. The server pushes the live broadcast stream pushed to the edge node to the entrance device of the established dedicated content distribution network, thereby entering the dedicated content distribution network through the entrance device to pull the stream, and transcoding the live broadcast stream after pulling the stream, so that the CDN-related inter-access service bandwidth is switched from the public network to the intranet.

[0084] The method of the embodiment of the present application is applied to a dedicated content delivery network, wherein the dedicated content delivery network is a dedicated network composed of multiple CDN nodes, multiple metropolitan area network nodes, multiple backbone network nodes, multiple source station IDCs, and multiple POP nodes.

[0085] Among them, CDN is composed of computer room nodes that can be spread across various regions and communication operators' networks around the world. CDN service providers deploy related software and hardware based on these computer room nodes to form a network. The computer room nodes that make up this network are usually called Point of Presence (POP) nodes at the edge of CDN.

[0086] Reference for next year Figure 4 To illustrate, in response to a node receiving a live stream push, the information acquisition device 101 acquires service-related information corresponding to the node.

[0087] The service information includes operator information and uplink server type information. The operator information includes various information that can be used to indicate the operator name, such as China Telecom or China Mobile.

[0088] Optionally, the operator information further includes information indicating a geographical location, for example, East China Telecom.

[0089] The device may classify servers in various ways, such as usage, chassis structure, and processing architecture, and set corresponding type information.

[0090] Optionally, the uplink server type information may include a public cloud 3-line server (BGP server), a single-line server in a company's self-built computer room, and an edge node server of a third-party cloud vendor.

[0091] The streaming forwarding device 102 forwards the live streaming to an ingress device of a dedicated content distribution network that matches the service-related information, thereby entering the dedicated content distribution network via the ingress device.

[0092] The entry device is a forwarding device deployed at the source station IDC of a dedicated content delivery network.

[0093] Optionally, the streaming forwarding device 102 determines a matching entry device based on geographic location information. Specifically, the service-related information includes the geographic location information of the node, and the method uses the entry device in the area of ​​the node's geographic location information as the entry device of the dedicated content delivery network that matches the service-related information.

[0094] According to one embodiment, if the live stream is received by a third-party edge node, the push stream forwarding device 102 forwards the live stream to the entry device of the matching dedicated content distribution network through the public network; if the live stream is received by a self-built edge node, the push stream forwarding device 102 forwards the live stream to the entry device of the matching dedicated content distribution network through the intranet.

[0095] The stream pulling processing device 103 pulls the live stream through a dedicated content distribution network, thereby performing transcoding processing on the pulled live stream.

[0096] According to one embodiment, the ingress device provides an intranet IP address and a public IP address, which serve as the intranet stream pull address and the public network stream pull address, respectively. The stream pull processing device 103 pulls the live stream via a dedicated content delivery network (CDN) based on the intranet stream pull address provided by the ingress device. If the live stream pull fails via the dedicated CDN, the stream pull processing device 103 pulls the stream via the public network based on the public network stream pull address.

[0097] According to one embodiment, the method further includes a device for obtaining the popularity type information of the live stream (hereinafter referred to as the "popularity type obtaining device"), a device for obtaining a corresponding back-to-source strategy based on the popularity type information, the back-to-source strategy including corresponding to different back-to-source access paths (hereinafter referred to as the "strategy obtaining device"), and a device for performing back-to-source processing on the live stream according to the back-to-source access path in the back-to-source strategy (hereinafter referred to as the "back-to-source processing device").

[0098] The popularity type obtaining device obtains the popularity type information of the live stream.

[0099] The popularity type information is obtained by classifying each live stream based on the popularity of the live stream.

[0100] For example, based on the predetermined number of historical live broadcast viewers, the live stream can be divided into four types or levels: cold stream, hot stream, warm stream and extremely cold stream.

[0101] The strategy acquisition device acquires a corresponding back-to-source strategy based on the popularity type information, where the back-to-source strategy includes corresponding back-to-source access paths.

[0102] The back-to-source strategy is to back-source popular live streams through the established dedicated content distribution network, and to back-source less popular live streams through the public network.

[0103] The back-to-source processing device performs back-to-source processing on the live stream according to the back-to-source access path in the back-to-source strategy.

[0104] For example, refer to Figure 3 The architecture shown in the figure uses a three-layer structure (L1, L2, and L3) from bottom to top to process access requests from user terminals back to the source. L1 corresponds to the self-built edge node (represented by the self-built CDN edge L1), L2 corresponds to the dedicated content delivery network (represented by the B2-CDN network), and L3 corresponds to the public network back to the source origin and the public network back to the source EC.

[0105] The B2-CDN network has a ring structure, including multiple metropolitan area network nodes, backbone network nodes, source station IDC and POP nodes corresponding to different geographical locations.

[0106] This example categorizes live streams requested by users into four different levels of popularity: cold streams, hot streams, warm streams, and extremely cold streams.

[0107] Reference Figure 3 The forwarding path diagram shown in the figure shows the corresponding back-to-origin strategies for live streams with four different heat levels: cold stream, hot stream, warm stream, and extremely cold stream:

[0108] 1) For cold streams, the live stream is pushed to a geographically matching L2 node in the L2 layer, and then back-sourced via the public network L2. Back-sourced via the public network L2 refers to a stream at a certain L2 node. If a user accesses this stream at an edge node below another L2 node, the stream is retrieved via the L2 public network back-source and provided to the downstream edge node.

[0109] 2) For hot traffic, the live stream is pushed to the self-built edge node at the L1 layer. The self-built edge node at the L1 layer then pushes the stream to the corresponding node in the B2-CDN network at the L2 layer, and then back to the source through the public network L2.

[0110] 3) For the warm stream, the live stream is pushed to the self-built edge node in the L1 layer. The self-built edge node in the L1 layer then pushes the stream to the corresponding node in the B2-CDN network in the L2 layer, and then back to the source through the public network L2.

[0111] 4) For extremely cold streams, push the live stream to the public network back-to-source EC for public network back-to-source.

[0112] According to the device of the embodiment of the present application, a dedicated content distribution network consisting of multiple CDN nodes, multiple metropolitan area network nodes, multiple backbone network nodes, multiple source station IDCs and multiple POP nodes is constructed, and the live stream pushed to the edge node is pushed to the entrance device of the constructed dedicated content distribution network, thereby entering the dedicated content distribution network through the entrance device to pull the stream, and transcoding the live stream after pulling the stream, so that the CDN-related inter-access service bandwidth is switched from the public network to the intranet, reducing costs.

[0113] Based on the same inventive concept, an electronic device is also provided in an embodiment of the present application. The method corresponding to the electronic device may be the method for processing live streaming data in the aforementioned embodiment, and its principle of solving the problem is similar to that of the method. The electronic device provided in an embodiment of the present application includes: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor to enable the at least one processor to execute the methods and / or technical solutions of the aforementioned multiple embodiments of the present application.
