Description

Technology Field

[0001] The embodiments of the present disclosure relate to the field of computer technology, specifically to a method for acquiring video stream data, an apparatus, an electronic device, and a computer-readable medium. Background Technology

[0002] When a user watches a video stream through a mobile device, if the network to which the mobile device is connected switches between a mobile network and a wireless network, the video stream is interrupted during the network switching process. Therefore, seamless transition is implemented to require connection transition when a network switch occurs. Currently, when connection transition is performed, a method is typically used to implement the transition by adding one Layer 7 load balancing gateway and one Layer 4 gateway between the mobile device and the stream pooling service cluster. The problem to be solved

[0003] However, when connection transitions are performed in the manner described above, there is a technical problem in which the time it takes for stream pooling data packets to reach the stream pooling service cluster from the mobile terminal increases due to the addition of two multi-layered gateways between the mobile terminal and the stream pooling service cluster, thereby causing delays in the stream pooling data packets. At the same time, there is a technical problem in which hardware costs and server burdens increase because two depacking operations are required when the stream pooling data packets pass through the two multi-layered gateways. means of solving the problem

Effects of the invention

[0024] According to the embodiments of the present invention, the video stream data acquisition method of some embodiments of the present disclosure has the beneficial effect of preventing delays in stream pooling data packets to some extent and reducing the burden on the server because the stream pooling data packets do not require multiple depackings. Specifically, the cause of the delay in stream pooling data packets and the relatively large burden on the server lies in adding one Layer 7 load balancing gateway and one Layer 4 gateway between the mobile terminal and the stream pooling service cluster. Based on this, in the video stream acquisition method of some embodiments of the present disclosure, one bit is added to the connection identifier in the stream pooling data packet to store target room information, and direct forwarding back-to-the-source is performed on the data packet based on the target room information. Accordingly, since a Layer 7 gateway is not required between the mobile terminal and the stream pooling service cluster, delays in stream pooling data packets are prevented to some extent and the burden on the server is alleviated, while the routing speed of the stream pooling data packets is accelerated.

[0031] Hereinafter, the present disclosure will be described in detail by combining embodiments with reference to the attached drawings.

[0032] FIG. 1 is a schematic diagram of one application scenario of a method for acquiring video stream data of some embodiments of the present disclosure.

[0033] In the application scenario of FIG. 1, first, the computing device (101) can determine whether the room identifier (104) of the communication room receiving the stream pooling data packet (103) is the same as the target room identifier (105) included in the connection identifier of the stream pooling data packet (103) in response to receiving the stream pooling data packet (103) transmitted from the target terminal (102). Here, the stream pooling data packet (103) is generated when playing a video stream at the target terminal (102), and the target room identifier (105) is the room identifier of the communication room receiving the first stream pooling data packet generated when playing the video stream at the target terminal (102). Next, the computing device (101) can forward the stream pooling data packet (103) to a target communication room (106) corresponding to the target room identifier (105) in response to determining that the target room identifier (105) is different from the room identifier (104) of the communication room receiving the stream pooling data packet (103). Finally, the computing device (101) can obtain video stream data (107) through the target communication room (106).

[0034] It should be explained that the computing device (101) may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster consisting of multiple servers or terminal devices, or it may be composed of a single server or terminal device. When the computing device is software, it may be installed on the hardware device listed above. This may be implemented, for example, as multiple software or software modules for providing distributed services, or as a single software or software module. This is not specifically limited here.

[0035] It should be understood that the number of computing devices in FIG. 1 is exemplary. Depending on the needs, any number of computing devices may be used.

[0036] Continuing with reference to FIG. 2, a process (200) of some embodiment of a method for acquiring video stream data according to the present disclosure is illustrated. The method for acquiring video stream includes the following steps.

[0037] In step (201), in response to receiving a stream pooling data packet transmitted from a target terminal, it is determined whether the room identifier of the communication room receiving the stream pooling data packet is the same as the target room identifier included in the connection identifier of the stream pooling data packet.

[0038] In some embodiments, the entity executing the method for acquiring video stream data (e.g., the computing device (101) illustrated in FIG. 1) may determine whether the communication room identifier of the stream pooling data packet is the same as the target room identifier included in the connection identifier of the stream pooling data packet in response to receiving a stream pooling data packet transmitted from the target terminal. Here, the stream pooling data packet may be generated when playing a video stream at the target terminal, and the target room identifier may be the communication room identifier of the first stream pooling data packet generated when playing a video stream at the target terminal. The video stream may be a live video stream or an on-demand video stream. The stream pooling data packet may be a QUIC (Quick UDP Internet Connection) packet. The target terminal may be a mobile terminal, e.g., a mobile phone, a tablet computer, etc.

[0039] The communication channel receiving the stream pooling data packet may be a communication channel corresponding to the network connected when the target terminal transmits the stream pooling data packet. The network connected during the process of the target terminal playing the video stream may be a mobile network or a wireless network. The network connected during the process of the target terminal playing the video stream may switch between a mobile network and a wireless network.

[0040] When the target terminal transmits the first stream pooling data packet, it sets the communication channel corresponding to the currently connected network as the target communication channel. Then, it records the communication channel identifier of the corresponding target communication channel as the target communication channel identifier in the connection identifier of the first stream pooling data packet. Subsequently, during the video stream playback process, the target communication channel identifier is recorded in the connection identifier of the stream pooling data packet to be generated subsequently.

[0041] If the room identifier of the communication room in the stream pooling data packet is identical to the target room identifier included in the connection identifier within the stream pooling data packet, it indicates that the communication room receiving the stream pooling data packet and the communication room receiving the first stream pooling data packet are the same communication room. Therefore, video stream data can be obtained directly through the communication room receiving the stream pooling data packet without the need for a connection transition.

[0042] If the room identifier of the communication room in the stream pooling data packet differs from the room identifier included in the connection identifier within the stream pooling data packet, it indicates that the communication room receiving the stream pooling data packet and the communication room receiving the first stream pooling data packet are different communication rooms; that is, it indicates that a switch has occurred between a mobile network and a wireless network in the connected network during the process of the target terminal playing the live video stream. Therefore, in order to ensure that the video stream continues to be played smoothly on the target terminal when a network switch occurs, it is necessary to forward the stream pooling data packet to the target communication room through a connection back-to-the-source operation.

[0043] Accordingly, it is possible to determine whether the communication room receiving the current stream pooling data packet is the target communication room through the target room identifier included in the connection identifier of the stream pooling data packet. Thus, fast routing of the stream pooling data packet is implemented.

[0044] For example, when the target terminal transmits the stream pooling data packet, if the connected network is Changchun Mobile's 5G network, the communication channel receiving the stream pooling data packet may be Changchun Mobile's channel.

[0045] In some selectable implementation methods of some embodiments, the target communication method is,

[0046] During the process of the above target terminal playing the above video, when the first stream pooling data packet is generated, the communication method corresponding to the connected network can be determined as the target communication method through a step of determining the target communication method.

[0047] Accordingly, when the first stream pooling data packet is generated, the communication channel corresponding to the network to which the target terminal is connected can be determined as the target communication channel. This enables fast routing of the stream pooling data packet when a subsequent network switch occurs.

[0048] In step (202), in response to determining that the room identifier of the target communication room is different from the room identifier of the communication room receiving the stream pooling data packet, the stream pooling data packet is forwarded to the target communication room corresponding to the target room identifier.

[0049] In some embodiments, the executing entity may forward the stream pooling data packet to a target communication room corresponding to the target room identifier in response to determining that the target room identifier is different from the room identifier of the communication room receiving the stream pooling data packet.

[0050] In step (203), video stream data is obtained through the target communication channel.

[0051] In some embodiments, the implementing entity can forward the stream pooling data packet to the target communication channel and then obtain the video stream data returned from the target communication channel.

[0052] In some selectable implementations of some embodiments, the executing entity may further perform the following steps.

[0053] First, the stream pooling data packet is transmitted to any one of the protocol switching servers in the communication room using the target internal gateway protocol. Here, the target internal gateway protocol may be OSPF (Open Shortest Path First). The protocol switching server may be any QUIC server in the QUIC server cluster. The QUIC server can obtain video stream data from the Content Allocation Delivery Network edge node after converting the QUIC protocol to the HTTP (Hyper Text Transfer Protocol) protocol.

[0054] Accordingly, by using the target internal gateway protocol, the stream pooling data packet can be transmitted to any one protocol switching server in the communication direction through at least one shortest routing path, thereby increasing the routing speed of the stream pooling data packet.

[0055] Secondly, a stream pooling service instance is assigned to the stream pooling data packet using an independent load service of any one of the aforementioned protocol switching servers. Here, the independent load service may be an operating system kernel-level load service. For example, it may be nftable.

[0056] Therefore, the burden on the server is reduced through operating system kernel-level load services.

[0057] Thirdly, in response to confirming that the target room identifier is identical to the room identifier of the communication room, video stream data is obtained through the communication room using the stream pooling service instance. Here, the stream pooling service instance can first convert the stream pooling data packet into an HTTP protocol data packet, and then obtain video stream data from a CDN (Content Delivery Network) server in the communication room.

[0058] The above embodiments of the present disclosure have the following beneficial effects. Through the video stream data acquisition method of some embodiments of the present disclosure, delays in stream pooling data packets can be prevented to some extent, and at the same time, since stream pooling data packets do not require multiple depackings, the burden on the server can be reduced. Specifically, the cause of delays in stream pooling data packets and the relatively high burden on the server lies in adding one Layer 7 gateway and one Layer 4 gateway between the mobile terminal and the stream pooling service cluster. Based on this, in the video stream data acquisition method of some embodiments of the present disclosure, one bit is added to the connection identifier in the stream pooling data packet to store target room information, and direct forwarding back-to-the-source is performed on the data packet based on the target room information. Accordingly, since a Layer 7 gateway is not required between the mobile terminal and the stream pooling service cluster, delays in stream pooling data packets are prevented to some extent, the burden on the server is alleviated, and the routing speed of the stream data packet is accelerated.

[0059] Referring further to FIG. 3, a process (300) of another embodiment of a method for acquiring video stream data is illustrated. The process (300) of the method for acquiring video stream data includes the following steps.

[0060] In step (301), in response to receiving a stream pooling data packet transmitted from a target terminal, it is determined whether the room identifier of the communication room receiving the stream pooling data packet is the same as the target room identifier included in the connection identifier of the stream pooling data packet.

[0061] In some embodiments, the specific implementation method of step (301) and the technical effect thereof can be described by referring to step (201) in the embodiment corresponding to FIG. 2 and will not be described again here.

[0062] In step (302), the stream pooling data packet is forwarded to any one of the protocol switching servers in the communication room using the target internal gateway protocol.

[0063] In some embodiments, the entity executing the method for acquiring video stream data (e.g., the computing device (101) of FIG. 1) may transmit the stream pooling data packet to any one of the protocol switching servers in the communication room using a target internal gateway protocol. Here, the target internal gateway protocol may be OSPF. The protocol switching server may be any QUIC server in the QUIC server cluster. The QUIC server may convert the QUIC protocol to the HTTP protocol and then acquire video stream data from the allocated content delivery network edge node.

[0064] Accordingly, by using the target internal gateway protocol, the stream pooling data packet can be transmitted to any one of the protocol switching servers in the communication room via at least one shortest routing path, thereby increasing the routing speed of the stream pooling data packet.

[0065] In step (303), an independent load service of any one of the protocol switching servers is used to assign a stream pooling service instance to the stream pooling data packet.

[0066] In some embodiments, the executing entity allocates a stream pooling service instance to the stream pooling data packet using an independent load service of any one of the protocol switching servers. Here, the independent load service may be an operating system kernel-level load service. For example, it may be nftable. Accordingly, the load on the server can be reduced through the operating system kernel-level load service.

[0067] In step (304), in response to determining that the target room identifier is different from the communication room identifier, a stream pooling service instance is used to forward the stream pooling data packet to the target communication room corresponding to the target room identifier.

[0068] In some embodiments, the executing entity may forward the stream pooling data packet to the target communication room corresponding to the target room identifier using the stream pooling service instance in response to determining that the target room identifier is different from the communication room identifier.

[0069] Accordingly, data latency is reduced by integrating the forwarding back-to-the-source function into the stream pooling service instance and eliminating the need for a separate Layer 7 load balancing gateway. At the same time, single-point failures of the Layer 7 load balancing gateway are reduced. Additionally, costs can be reduced as there is no need to deploy a Layer 7 load balancing gateway.

[0070] In step (305), a target stream pooling service instance that matches the stream pooling data packet among the target protocol switching servers in the target communication room is determined.

[0071] In some embodiments, the executing entity may determine a target stream pooling service instance that matches the stream pooling data packet among the target protocol switching servers in the target communication method.

[0072] The above target communication method receives the first stream pooling data packet generated during the process of playing the video stream at the target terminal, and then transmits to the target terminal the protocol conversion server identifier of the protocol conversion server receiving the first stream pooling data packet among the target communication methods, and the stream pooling service instance identifier of the stream pooling service instance allocation assigned to the first stream pooling data packet among the protocol conversion servers, so that the target terminal records the protocol conversion server identifier and the stream pooling service instance identifier in a stream pooling data packet to be subsequently generated. Accordingly, the executing entity can determine the target protocol conversion server and the target stream pooling server instance among the target protocol conversion servers based on the protocol conversion server identifier and the stream pooling service instance identifier included in the stream pooling data packet.

[0073] In a selectable implementation method of some embodiments, the step of the executing entity determining a target stream pooling service instance that matches the stream pooling data packet among the target protocol switching servers in the target communication method may include the following steps.

[0074] First, a mapping table is obtained from the cache server of the protocol switching server cluster among the above target communication methods. Here, the mapping table includes mapping information, and the mapping information includes a connection identifier, a protocol switching server identifier, and a stream pooling server instance identifier. The data stored in the cache server may be data shared by the protocol switching server cluster.

[0075] For example, the above cache server may be a Redis server.

[0076] Secondly, mapping information in which the connection identifier included in the above mapping table is identical to the connection identifier in the stream pooling data packet is selected as the target mapping information.

[0077] Third, the protocol switching server corresponding to the protocol switching server identifier among the above-mentioned goal mapping information is confirmed as the target protocol switching server.

[0078] Fourth, among the above-mentioned target protocol switching servers, the stream pooling service instance corresponding to the stream pooling service instance identifier in the above-mentioned target mapping information is determined as the target stream pooling service instance that matches the above-mentioned stream pooling data packet.

[0079] Optionally, the mapping information in the above mapping table is determined through the following steps.

[0080] First, the connection identifier in the first stream pooling data packet, the protocol switching server identifier of the target protocol switching server, and the stream pooling service instance identifier of the target stream pooling service instance are determined as mapping information.

[0081] Secondly, the above mapping information is recorded in the mapping table among the cache servers.

[0082] Optionally, the above target protocol switching server and target stream pooling service instance can be determined through the following steps.

[0083] First, in response to the confirmation that the target communication room receives the first stream pooling data packet, one protocol switching server from the protocol switching server cluster among the target communication rooms is selected as the target protocol switching server. Here, the target protocol switching server may be randomly selected from the protocol switching server cluster.

[0084] Secondly, using an independent load service among the target protocol switching servers, a stream pooling service instance is assigned to the first stream pooling data packet, and the stream pooling service instance is designated as the target stream pooling service instance. Here, a single stream pooling service instance can be created for the first stream pooling data packet using an independent load service.

[0085] For example, with reference to FIG. 4, first, in response to the confirmation that the target communication room (401) receives the first stream pooling data packet (402), one protocol switching server from the protocol switching server cluster (403) in the target communication room (401) can be selected as the target protocol switching server (404). Next, using an independent load service among the target protocol switching servers (404), a stream pooling service instance (405) can be assigned to the first stream pooling data packet (402), and the stream pooling service instance can be made the target stream pooling service instance.

[0086] In step (306), video stream data is obtained from the allocated content delivery network edge node using the target stream pooling service instance.

[0087] In some embodiments, the executing entity may first convert the stream pooling data packet into an HTTP protocol data packet using the target stream pooling service instance. Next, video stream data is obtained from an allocated content transmission network edge node in the communication channel.

[0088] In some selectable implementations of some embodiments, the executing entity may transmit the video stream data to the target terminal.

[0089] As can be seen in FIG. 3, compared to the description of some embodiments corresponding to FIG. 2, the process (300) of the method for acquiring video stream data of some embodiments corresponding to FIG. 3 illustrates detailed steps for forwarding stream pooling data packets and acquiring video stream data. Accordingly, the method described in this embodiment can further increase the routing speed of stream pooling data packets and reduce the burden on the server by utilizing the target internal gateway protocol and independent load service.
