[0019] Hereinafter, the embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, the present disclosure can be embodied in various forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to make the present disclosure more clear and complete. It should be noted that the drawings and embodiments of the present disclosure are merely illustrative and do not limit the scope of protection of the present disclosure.

[0020] For convenience of explanation, only parts related to the present invention are shown in the drawings. The embodiments and features of the embodiments of the present disclosure can be combined with each other unless a contradiction occurs.

[0021] It should be noted that concepts such as "first" and "second" referred to in this disclosure are merely intended to distinguish different devices, modules, or units, and are not intended to define the order or interdependence of functions performed by these devices, modules, or units.

[0022] Furthermore, the limiting terms "one" and "multiple" referred to in this disclosure are exemplary rather than limiting, and should be understood by one of ordinary skill in the art to mean "at least one" unless the context clearly indicates otherwise.

[0023] The names of messages or information exchanged between multiple devices in the embodiments of the present disclosure are merely exemplary and are not intended to limit the scope of these messages or information.

[0024] The method of obtaining the related video stream data, for example, by adding one 7-layer load balancing gateway and one 4-layer gateway between the mobile terminal and the pull stream service cluster to realize the connection migration, often has the following technical problems: Adding two multi-layer gateways between the mobile terminal and the pull stream service cluster may increase the time it takes for the pull stream data packet to reach the pull stream service cluster from the mobile terminal, which may result in the delay of the pull stream data packet; At the same time, when the pull stream data packet passes through the two multi-layer gateways, it needs to perform a total of two unpacking processes, which increases the hardware cost and the burden on the server.

[0025] In order to solve the above-mentioned problems, some embodiments of the present disclosure provide a method for acquiring video stream data and an apparatus for acquiring video stream data, which can avoid delays in pull stream data packets to a certain extent, and eliminate the need to perform multiple unpacking processes on pull stream data packets, thereby reducing the burden on the server.

[0026] Hereinafter, the present disclosure will be described in detail with reference to the drawings and embodiments.

[0027] FIG. 1 is a schematic diagram illustrating an application scene of a method for obtaining video stream data according to some embodiments of the present disclosure.

[0028] In the application scenario of FIG. 1, first, in response to receiving a pull stream data packet 103 sent by a target terminal 102, the computing device 101 can determine whether the equipment room identifier 104 of the communication equipment room that receives the pull stream data packet 103 is the same as the target equipment room identifier 105 included in the connection identifier in the pull stream data packet 103. Here, the pull stream data packet 103 is generated when the target terminal 102 plays a video stream, and the target equipment room identifier 105 is the equipment room identifier of the communication equipment room that receives the first pull stream data packet generated when the target terminal 102 plays the video stream. Then, in response to determining that the target equipment room identifier 105 is different from the equipment room identifier 104 of the communication equipment room that receives the pull stream data packet 103, the computing device 101 can forward the pull stream data packet 103 to the target communication equipment room 106 corresponding to the target equipment room identifier 105. Finally, the computing device 101 can obtain the video stream data 107 via the target communication equipment room 106 .

[0029] The computing device 101 may be hardware or software. If the computing device is hardware, it may be implemented as a distributed server cluster consisting of multiple servers or terminal devices, or as a single server or a single terminal device. If the computing device is software, it may be installed on the listed hardware devices. It may be implemented, for example, as multiple software or software modules for providing distributed services, or as a single software or software module. There is no particular limitation here.

[0030] It should be understood that the number of computing devices in Figure 1 is merely exemplary, and any number of computing devices may be used according to the needs of the implementation.

[0031] Reference is now made to Figure 2, which illustrates a flow 200 of some embodiments of a method for acquiring video stream data according to the present disclosure. The method for acquiring video stream data includes the following steps.

[0032] In step 201, in response to receiving a pull stream data packet transmitted from a target terminal, it is determined whether the equipment room identifier of the communication equipment room that received the pull stream data packet is the same as the target equipment room identifier included in the connection identifier in the pull stream data packet.

[0033] In some embodiments, the execution subject of the method for obtaining video stream data (the computing device 101 shown in FIG. 1) can determine whether the equipment room identifier of the communication equipment room that receives the pull stream data packet is the same as the target equipment room identifier included in the connection identifier in the pull stream data packet in response to receiving a pull stream data packet transmitted from a target terminal. Here, the pull stream data packet may be generated when the target terminal plays a video stream, and the target equipment room identifier may be the equipment room identifier of the communication equipment room that receives the first pull stream data packet generated when the target terminal plays the video stream. The video stream may be a live distribution video stream or an on-demand distribution video stream. The pull stream data packet may be a QUIC (Quick UDP Internet Connection, Quick UDP (User Datagram Protocol) Internet Connection) data packet. The target terminal may be a mobile terminal, such as a mobile phone, a tablet PC, etc.

[0034] The communication equipment room receiving the pull stream data packet may be a communication equipment room corresponding to the network connected when the target terminal transmits the pull stream data packet. In the process of the target terminal playing the video stream, the network connected may be a mobile communication network or a wireless communication network. In the process of the target terminal playing the video stream, the target terminal may switch the network connected between the mobile communication network and the wireless communication network.

[0035] When the target terminal transmits the first pull stream data packet, the target terminal may select a communication equipment room corresponding to a currently connected network as a target communication equipment room, and write the communication equipment room identifier of the target communication equipment room as a target communication equipment room identifier into the connection identifier of the first pull stream data packet, and write the target communication equipment room identifier into the connection identifier of the subsequently generated pull stream data packet in the process of playing the video stream.

[0036] If the equipment room identifier of the communication equipment room of the pull stream data packet is the same as the target equipment room identifier included in the connection identifier in the pull stream data packet, it indicates that the communication equipment room that receives the pull stream data packet is the same as the communication equipment room that receives the first pull stream data packet, so that there is no need to perform connection transfer, and the video stream data can be directly obtained through the communication equipment room that receives the pull stream data packet.

[0037] If the equipment room identifier of the communication equipment room of the pull stream data packet is different from the target equipment room identifier included in the connection identifier in the pull stream data packet, it indicates that the communication equipment room that receives the pull stream data packet is different from the communication equipment room that receives the first pull stream data packet, that is, in the process of the target terminal playing the live distribution video stream, the connected network is switched between the mobile communication network and the wireless communication network. Therefore, when a network handover occurs, in order to enable the target terminal to continue playing the video stream smoothly, the pull stream data packet needs to be transferred to the target communication equipment room by a connection return operation.

[0038] Thus, the target equipment room identifier included in the connection identifier in the pull stream data packet can be used to determine whether the communication equipment room currently receiving the pull stream data packet is the target communication equipment room, thereby realizing high-speed routing of the pull stream data packet.

[0039] As an example, if the network connected when the target terminal transmits the pull stream data packet is China Mobile (Changchun)'s 5G network, the communication equipment room receiving the pull stream data packet may be a China Mobile (Changchun) equipment room.

[0040] In some optional embodiments of some embodiments, the target communications equipment room may be identified by the following steps.

[0041] When the target terminal generates a first pull stream data packet in the process of playing the video stream, it identifies a communication equipment room corresponding to a connected network as a target communication equipment room.

[0042] Thus, when the first pull stream data packet is generated, the communication equipment room corresponding to the network connected to the target terminal can be specified as the target communication equipment room. Furthermore, when a handover occurs to a subsequent network, high-speed routing of the pull stream data packet can be realized.

[0043] In step 202, in response to determining that the target equipment room identifier is different from the equipment room identifier of the communications equipment room that received the pull stream data packet, forward the pull stream data packet to the target communications equipment room corresponding to the target equipment room identifier.

[0044] In some embodiments, the executing entity may forward the pull stream data packet to a target communications equipment room corresponding to the target equipment room identifier in response to determining that the target equipment room identifier is different from the equipment room identifier of the communications equipment room from which the pull stream data packet was received.

[0045] In step 203, video stream data is obtained via the target communication equipment room.

[0046] In some embodiments, the execution entity can obtain video stream data returned from the target communications equipment room after forwarding the pull stream data packet to the target communications equipment room.

[0047] In some optional aspects of some embodiments, the execution entity may further perform the following steps:

[0048] In the first step, the pull stream data packet is sent to any protocol conversion server in the communication equipment room by a target internal gateway protocol. The target internal gateway protocol may be OSPF (Open Shortest Path First). The protocol conversion server may be any QUIC server in a QUIC server cluster. The QUIC server can obtain video stream data from an edge node of a content delivery network after converting the QUIC protocol into HTTP (Hyper Text Transfer Protocol) protocol.

[0049] Thus, the target internal gateway protocol can be used to transmit the pull stream data packet to any one of the protocol conversion servers in the communication equipment room via at least one shortest routing path, thereby accelerating the routing speed of the pull stream data packet.

[0050] In the second step, a pull stream service instance is assigned to the pull stream data packet by a standalone load service of any one of the protocol conversion servers, where the standalone load service may be a kernel-level load service of an operating system, such as nftable.

[0051] This allows the operating system kernel-level load services to offload the server.

[0052] In a third step, in response to determining that the target equipment room identifier is the same as the equipment room identifier of the communication equipment room, the pull stream service instance is used to obtain video stream data by the communication equipment room, where the pull stream service instance may first convert the pull stream data packet into an HTTP protocol data packet, and then obtain the video stream data from a Content Delivery Network (CDN) server in the communication equipment room.

[0053] The above embodiments of the present disclosure have the beneficial effect that the method of acquiring video stream data of some embodiments of the present disclosure can avoid the delay of the pull stream data packet to a certain extent, and at the same time, there is no need to perform the unpacking process on the pull stream data packet multiple times, and the burden on the server can be reduced. Specifically, the delay of the pull stream data packet and the increased burden on the server are caused by the addition of a 7-layer gateway and a 4-layer gateway between the mobile terminal and the pull stream service cluster. Based on this, the method of acquiring video stream data of some embodiments of the present disclosure adds one byte to the connection identifier in the pull stream data packet to store the information of the target equipment room, and directly forwards the data packet to the sender according to the information of the target equipment room. This eliminates the need for a 7-layer gateway to exist in the mobile terminal and the pull service cluster, and can avoid the delay of the pull stream data packet to a certain extent, reduce the burden on the server, and increase the routing speed of the pull stream data packet.

[0054] 3, which illustrates a flow 300 of some other embodiments of a method for acquiring video stream data. The flow 300 of the method for acquiring video stream data includes the following steps:

[0055] In step 301, in response to receiving a pull stream data packet transmitted from a target terminal, it is determined whether the equipment room identifier of the communication equipment room that received the pull stream data packet is the same as the target equipment room identifier included in the connection identifier in the pull stream data packet.

[0056] In some embodiments, the specific implementations of step 301 and the technical effects achieved thereby may refer to step 201 in the corresponding embodiments in FIG. 2, and the description thereof will be omitted here.

[0057] In step 302, the pull stream data packet is sent to any one of the protocol conversion servers in the communication equipment room according to the target interior gateway protocol.

[0058] In some embodiments, an entity performing the method for obtaining video stream data (such as the computing device 101 shown in FIG. 1 ) can send the pull stream data packet to any protocol conversion server in the communication equipment room by a target internal gateway protocol. The target internal gateway protocol can be OSPF. The protocol conversion server can be any QUIC server in a QUIC server cluster. The QUIC server can obtain the video stream data from an edge node of a content delivery network after converting the QUIC protocol into an HTTP protocol.

[0059] Thus, the target internal gateway protocol can be used to transmit the pull stream data packet to any one of the protocol conversion servers in the communication equipment room via at least one shortest routing path, thereby accelerating the routing speed of the pull stream data packet.

[0060] In step 303, a pull stream service instance is assigned to the pull stream data packet by a standalone load service of any one of the protocol conversion servers.

[0061] In some embodiments, the execution subject can allocate a pull stream service instance to the pull stream data packet by a standalone load service of any of the protocol conversion servers. The standalone load service can be a kernel-level load service of an operating system, such as nftable. This allows the load of the server to be reduced by the kernel-level load service of the operating system.

[0062] In step 304, in response to determining that the target equipment room identifier is different from the equipment room identifier of the communications equipment room, a pull stream service instance is utilized to forward the pull stream data packet to the target communications equipment room corresponding to the target equipment room identifier.

[0063] In some embodiments, in response to determining that the target equipment room identifier is different from the equipment room identifier of the communications equipment room, the executing entity can utilize the pull stream service instance to forward the pull stream data packet to the target communications equipment room corresponding to the target equipment room identifier.

[0064] Therefore, by integrating the forwarding function to the sender into the pull stream service instance, the seventh layer load balancing gateway no longer exists, and the data delay is reduced. At the same time, the single point of failure caused by the seventh layer load balancing gateway is reduced. In addition, since there is no need to deploy the seventh layer load balancing gateway, the cost can also be reduced.

[0065] In step 305, a target pull stream service instance that matches the pull stream data packet is determined in a target protocol conversion server in the target communication device room.

[0066] In some embodiments, the execution entity can determine a target pull stream service instance in a target protocol conversion server in the target communication equipment room that matches the pull stream data packet.

[0067] After receiving the first pull stream data packet generated by the target terminal in the process of playing the video stream, the target communication equipment room may send to the target terminal the protocol conversion server identifier of the protocol conversion server that receives the first pull stream data packet in the target communication equipment room and the pull stream service instance identifier of the pull stream service instance that is assigned to the first pull stream data packet in the protocol conversion server, so that the target terminal can write the protocol conversion server identifier and the pull stream service instance identifier into the subsequently generated pull stream data packet. Thus, the execution entity can determine the target protocol conversion server and the target pull stream service instance in the target protocol conversion server according to the protocol conversion server identifier and the pull stream service instance identifier included in the pull stream data packet.

[0068] In some optional embodiments of some embodiments, the step of the executing entity determining a target pull stream service instance that matches the pull stream data packet at a target protocol conversion server in the target communication equipment room may include the following steps:

[0069] In the first step, a mapping table is obtained from a cache server of a protocol conversion server cluster in the target communication device room, where the mapping table includes mapping information, the mapping information including a connection identifier, a protocol conversion server identifier, and a pull stream service instance identifier. The data stored in the cache server may be data shared by the protocol conversion server cluster.

[0070] As an example, the cache server may be a Redis server.

[0071] In the second step, the mapping information, the connection identifier of which is the same as the connection identifier in the pull stream data packet, is selected from the mapping table as the target mapping information.

[0072] In the third step, a protocol conversion server corresponding to the protocol conversion server identifier in the target mapping information is determined as a target protocol conversion server.

[0073] In a fourth step, in the target protocol conversion server, a pull stream service instance corresponding to the pull stream service instance identifier in the target mapping information is determined as a target pull stream service instance matching the pull stream data packet.

[0074] Optionally, the mapping information in said mapping table is determined by the following steps:

[0075] In the first step, the connection identifier in the first pull stream data packet, the protocol conversion server identifier of the target protocol conversion server, and the pull stream service instance identifier of the target pull stream service instance are determined as mapping information.

[0076] In a second step, the mapping information is recorded in a mapping table in the cache server.

[0077] Optionally, the target protocol conversion server and the target pull stream service instance may be determined by the following steps.

[0078] In a first step, in response to determining that the target communication equipment room has received the first pull stream data packet, a protocol conversion server is selected from a protocol conversion server cluster of the target communication equipment room as a target protocol conversion server, and the target protocol conversion server may be randomly selected from the protocol conversion server cluster.

[0079] In a second step, a pull stream service instance is assigned to the first pull stream data packet by a standalone load service of the target protocol conversion server, and the pull stream service instance is set as a target pull stream service instance, where the standalone load service may create one pull stream service instance for the first pull stream data packet.

[0080] 4 as an example, first, in response to determining that the target communication equipment room 401 receives the first pull stream data packet 402, one protocol conversion server can be selected from a protocol conversion server cluster 403 in the target communication equipment room 401 as a target protocol conversion server 404. Then, a pull stream service instance 405 can be assigned to the first pull stream data packet 402 by a standalone load service of the target protocol conversion server 404, and the pull stream service instance can be set as a target pull stream service instance.

[0081] In step 306, the target pull stream service instance is used to obtain video stream data from an edge node of the content delivery network.

[0082] In some embodiments, the execution entity can first convert the pull stream data packets into HTTP protocol data packets using the target pull stream service instance, and then obtain video stream data from an edge node of a content delivery network in the communication equipment room.

[0083] In some optional embodiments of some embodiments, the actor may transmit the video stream data to the target terminal.

[0084] As can be seen from Fig. 3, compared with the corresponding embodiments of Fig. 2, the flow 300 of the method for obtaining video stream data in the corresponding embodiments of Fig. 3 embodies detailed steps of forwarding pull stream data packets and obtaining video stream data. Therefore, the solutions described in these embodiments can speed up the routing speed of pull stream data packets and reduce the load of servers through the target interior gateway protocol and standalone load service.

[0085] Referring to FIG. 5, as an implementation of the method shown in each of the above figures, the present disclosure provides several embodiments of an apparatus for acquiring video stream data, which correspond to the embodiment of the method shown in FIG. 2, and the apparatus can be specifically applied to various electronic devices.

Here, the judging unit 501 is configured to, in response to receiving a pull stream data packet sent from a target terminal, judge whether an equipment room identifier of a communication equipment room that receives the pull stream data packet is the same as a target equipment room identifier included in a connection identifier in the pull stream data packet.

[0088] In an optional embodiment of some embodiments, the target communications equipment room is determined by a step of determining as the target communications equipment room the communications equipment room corresponding to the network to which the target terminal was connected when it generated a first pull stream data packet in the process of playing the video stream.

[0089] In an optional embodiment of some embodiments, the target protocol conversion server and target pull stream service instance are determined by the steps of: selecting a protocol conversion server from a protocol conversion server cluster in the target communications equipment room as the target protocol conversion server in response to determining that the target communications equipment room has received the first pull stream data packet; and assigning a pull stream service instance to the first pull stream data packet by a standalone load service of the target protocol conversion server and designating the pull stream service instance as the target pull stream service instance.
