DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, 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 enable a more clear and complete understanding of the present disclosure. It should be noted that the drawings and embodiments of the present disclosure are merely illustrative and do not limit the protection scope of the present disclosure.

[0020] For convenience of explanation, only the parts related to the invention are shown in the drawings. The embodiments of the present disclosure and the features in the embodiments can be combined with each other as long as there is no contradiction.

[0021] Note that the concepts such as "first" and "second" mentioned in the present disclosure are only for distinguishing different devices, modules, or units, and are not for defining the order or interdependence of the functions executed by these devices, modules, or units.

[0022] Furthermore, the qualifiers "one" and "a plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand them as "at least one" unless otherwise specified in the context.

[0023] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are merely illustrative and are not for limiting the scope of these messages or information.

[0024] For example, when implementing the migration of the connection by adding one 7-layer load balancing gateway and one 4-layer gateway between the mobile terminal and the pull stream service cluster to obtain related video stream data, the following technical problems often exist. When adding two multi-layer gateways between the mobile terminal and the pull stream service cluster, the time for the pull stream data packet to reach the pull stream service cluster from the mobile terminal may increase, resulting in a 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 is necessary to perform a total of two unpacking processes, increasing the hardware cost and the burden on the server.

[0025] To solve the above problems, some embodiments of the present disclosure propose a method for acquiring video stream data and an apparatus for acquiring video stream data, which can avoid the delay of pull stream data packets to a certain extent, and there is no need to perform unpacking processing on pull stream data packets multiple times, thus 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 showing an application scenario of a method for acquiring 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 transmitted by a target terminal 102, a computing device 101 can determine whether a device room identifier 104 of the communication device room where the pull stream data packet 103 is received is the same as a target device room identifier 105 included in a 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 device room identifier 105 is the device room identifier of the communication device 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 device room identifier 105 is different from the device room identifier 104 of the communication device room where the pull stream data packet 103 is received, the computing device 101 can transfer the pull stream data packet 103 to a target communication device room 106 corresponding to the target device room identifier 105. Finally, the computing device 101 can acquire video stream data 107 via the target communication device room 106.

[0029] The above computing device 101 may be hardware or software. When the computing device is hardware, it can be implemented as a distributed server cluster composed of multiple servers or terminal devices, or as a single server or a single terminal device. When 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. It is not particularly limited here.

[0030] It should be understood that the number of computing devices in FIG. 1 is merely exemplary. The number of computing devices may be arbitrarily increased or decreased according to the needs of implementation.

[0031] Next, refer to FIG. 2 showing the flow 200 of some embodiments of the method for acquiring video stream data according to the present disclosure. The method for acquiring the 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 device room identifier of the communication device room that has received the pull stream data packet is the same as the target device room identifier included in the connection identifier within the pull stream data packet.

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

[0034] The communication device room that received the pull stream data packet may be the communication device room corresponding to the network to which the target terminal is connected when transmitting the pull stream data packet. In the process of the target terminal playing the video stream, the connected network may be a mobile communication network or a wireless communication network. The target terminal may switch the connected network between a mobile communication network and a wireless communication network in the process of playing the video stream.

[0035] When sending the first pull stream data packet, the target terminal may use the communication equipment room corresponding to the currently connected network as the target communication equipment room. And write the equipment room identifier of the target communication equipment room as the target communication equipment room identifier into the connection identifier of the first pull stream data packet. Also, in the process of playing the video stream, write the target communication equipment room identifier into the connection identifiers of the subsequently generated pull stream data packets.

[0036] The above pull stream data packet received If the equipment room identifier of the communication equipment room is the same as the target equipment room identifier included in the connection identifier within the above pull stream data packet, it indicates that the communication equipment room that received the above pull stream data packet is the same communication equipment room as the communication equipment room that received the first pull stream data packet. Therefore, there is no need to perform a connection transition, and the video stream data can be directly obtained through the communication equipment room that received the above pull stream data packet.

[0037] The above pull stream data packet received If the equipment room identifier of the communication equipment room is different from the target equipment room identifier included in the connection identifier within the above pull stream data packet, it indicates that the communication equipment room that received the above pull stream data packet is different from the communication equipment room that received the first pull stream data packet, that is, in the process of the target terminal playing the live video stream, the connected network has been switched between a mobile communication network and a wireless communication network. Therefore, in order to enable the target terminal to continue playing the video stream smoothly when a handover occurs in the network, it is necessary to transfer the above pull stream data packet to the target communication equipment room through a connection restoration operation.

[0038] Accordingly, it is possible to determine whether the communication device room currently receiving the pull stream data packet is the target communication device room based on the target device room identifier included in the connection identifier within the pull stream data packet. Thereby, high-speed routing of the pull stream data packet is realized.

[0039] As an example, if the network to which the target terminal is connected when transmitting the pull stream data packet is the 5G network of 'China Mobile (Changchun)', the communication device room receiving the pull stream data packet may be the device room of 'China Mobile (Changchun)'.

[0040] In some optional embodiments of some embodiments, the target communication device room can be identified by the following steps.

[0041] When the target terminal generates the first pull stream data packet in the process of playing the video stream, the communication device room corresponding to the connected network is identified as the target communication device room.

[0042] Accordingly, when the first pull stream data packet is generated, the communication device room corresponding to the network connected to the target terminal can be identified as the target communication device 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 device room identifier is different from the device room identifier of the communication device room that received the pull stream data packet, the pull stream data packet is transferred to the target communication device room corresponding to the target device room identifier.

[0044] In some embodiments, the execution entity may transfer the pull stream data packet to a target communication device room corresponding to the target device room identifier in response to determining that the target device room identifier is different from the device room identifier of the communication device room that received the pull stream data packet.

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

[0046] In some embodiments, after transferring the pull stream data packet to the target communication device room, the execution entity may acquire the video stream data returned from the target communication device room.

[0047] In some optional embodiments 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 device room by the 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 the QUIC server cluster. After converting the QUIC protocol to the HTTP (Hyper Text Transfer Protocol) protocol, the QUIC server can acquire video stream data from an edge node of the content delivery network.

[0049] Thereby, by using the target internal gateway protocol, the pull stream data packet can be sent to any protocol conversion server in the communication device room by at least one shortest routing path, and the routing speed of the pull stream data packet can be increased.

[0050] In the second step, the stand-alone load service of any of the above protocol conversion servers assigns a pull stream service instance to the pull stream data packet. Note that the stand-alone load service may be a load service at the kernel level of the operating system. For example, it may be nftable.

[0051] As a result, the load on the server is reduced by the load service at the kernel level of the operating system.

[0052] In the 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 video stream data is acquired from the communication equipment room using the pull stream service instance. Here, the pull stream service instance may first convert the pull stream data packet into an HTTP protocol data packet, and then acquire the video stream data from a CDN (Content Delivery Network) server in the communication equipment room.

[0053] Each of the above embodiments of the present disclosure can avoid the delay of pull stream data packets to a certain extent by the method of acquiring video stream data of some embodiments of the present disclosure. At the same time, it is not necessary to perform unpacking processing on the pull stream data packets multiple times, which has the beneficial effect of reducing the burden on the server. Specifically, the reason for the delay of the pull stream data packets and the increase in the burden on the server is that a 7-layer gateway and a 4-layer gateway are added 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 for storing the information of the target equipment room to the connection identifier in the pull stream data packet, and directly transfers the data packet to the source according to the information of the target equipment room. Thereby, it is not necessary to have a 7-layer gateway between the mobile terminal and the pull service cluster, the delay of the pull stream data packet can be avoided to a certain extent, the burden on the server can be reduced, and the routing speed of the pull stream data packet can be increased.

[0054] Refer to FIG. 3 showing Flow 300 of some other embodiments of the method for acquiring video stream data. Flow 300 of this method for acquiring video stream data includes the following steps.

[0055] In step 301, in response to receiving a pull stream data packet sent 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 embodiments of step 301 and the technical effects achieved thereby can refer to step 201 in the corresponding embodiments of FIG. 2, and the description thereof is omitted here.

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

[0058] In some embodiments, the execution subject of the method for obtaining video stream data (such as the computing device 101 shown in FIG. 1) can send the above pull stream data packet to any protocol conversion server in the communication device room according to the target interior gateway protocol. Note that the target interior gateway protocol may be OSPF. The protocol conversion server may be any QUIC server in the QUIC server cluster. The QUIC server can obtain video stream data from the edge node of the content delivery network after converting the QUIC protocol to the HTTP protocol.

[0059] Thereby, by using the target interior gateway protocol, the pull stream data packet is sent to any protocol conversion server in the communication device room through at least one of the shortest routing paths, and the routing speed of the pull stream data packet can be increased.

[0060] In step 303, a pull stream service instance is assigned to the pull stream data packet by the stand-alone load service of any protocol conversion server.

[0061] In some embodiments, the execution subject can assign a pull stream service instance to the pull stream data packet by the stand-alone load service of any protocol conversion server. Note that the stand-alone load service may be a load service at the kernel level of the operating system. For example, it is nftable. Thereby, the load of the server can be reduced by the load service at the kernel level 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 communication equipment room, a pull stream service instance is used to transfer the pull stream data packet to the target communication equipment room corresponding to the target equipment room identifier.

[0063] In some embodiments, the execution entity can, in response to determining that the target equipment room identifier is different from the equipment room identifier of the communication equipment room, use the pull stream service instance to transfer the pull stream data packet to the target communication equipment room corresponding to the target equipment room identifier.

[0064] Therefore, by integrating the transfer function to the source into the pull stream service instance, the 7-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 7-layer load balancing gateway is reduced. Also, since there is no need to deploy the 7-layer load balancing gateway, the cost can be reduced.

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

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

[0067] After the above-mentioned target communication equipment room receives the first pull stream data packet generated in the process of the above-mentioned target terminal playing the above-mentioned video stream, the protocol conversion server identifier of the protocol conversion server in the above-mentioned target communication equipment room that receives the above-mentioned first pull stream data packet and the pull stream service instance identifier of the pull stream service instance assigned to the above-mentioned first pull stream data packet in the above-mentioned protocol conversion server may be sent to the above-mentioned target terminal. As a result, the above-mentioned target terminal can write the above-mentioned protocol conversion server identifier and the above-mentioned pull stream service instance identifier into the subsequently generated pull stream data packets. Thereby, the above-mentioned execution entity can determine the target protocol conversion server and the target pull stream service instance in the above-mentioned target protocol conversion server based on the protocol conversion server identifier and the pull stream service instance identifier included in the above-mentioned pull stream data packet.

[0068] In some optional embodiments of some embodiments, the step in which the above-mentioned execution entity determines a target pull stream service instance that matches the above-mentioned pull stream data packet in the target protocol conversion server in the above-mentioned target communication equipment room may include the following steps.

[0069] In the first step, obtain a mapping table from the cache server of the protocol conversion server cluster in the above-mentioned target communication equipment room. Here, the above-mentioned mapping table contains mapping information, and the above-mentioned mapping information contains a connection identifier, a protocol conversion server identifier, and a pull stream service instance identifier. The data stored in the above-mentioned cache server may be data shared by the above-mentioned protocol conversion server cluster.

[0070] By way of example, the above-mentioned cache server may be a Redis server.

[0071] In the second step, mapping information whose contained connection identifier is the same as the connection identifier in the above pull stream data packet is selected from the above 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 above target mapping information is determined as the target protocol conversion server.

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

[0074] Optionally, the mapping information in the above mapping table is determined by the following steps.

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

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

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

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

[0079] In the second step, by means of the stand-alone load service of the target protocol conversion server, a pull stream service instance is assigned to the first pull stream data packet, and the pull stream service instance is used as the target pull stream service instance. Here, one pull stream service instance may be created for the first pull stream data packet by means of the stand-alone load service.

[0080] As an example, referring to FIG. 4, first, in response to determining that the target communication equipment room 401 has received the first pull stream data packet 402, one protocol conversion server can be selected from the protocol conversion server cluster 403 in the target communication equipment room 401 as the target protocol conversion server 404. Next, by means of the stand-alone load service of the target protocol conversion server 404, a pull stream service instance 405 can be assigned to the first pull stream data packet 402, and the pull stream service instance can be used as the target pull stream service instance.

[0081] In step 306, video stream data is acquired from the edge node of the content delivery network by using the target pull stream service instance.

[0082] In some embodiments, the above execution entity can first convert the above pull stream data packet into an HTTP protocol data packet using the above target pull stream service instance. Then, video stream data is acquired from an edge node of the content delivery network in the communication device room.

[0083] In some optional embodiments of some embodiments, the above execution entity may send the above video stream data to the above target terminal.

[0084] As can be seen from FIG. 3, compared with some corresponding embodiments of FIG. 2, the flow 300 of the method for acquiring video stream data in some corresponding embodiments of FIG. 3 embodies the detailed steps of transferring the pull stream data packet and acquiring the video stream data. Therefore, the solutions described in these embodiments can accelerate the routing speed of the pull stream data packet and reduce the server load through the target interior gateway protocol and the stand-alone load service.

[0085] Referring to FIG. 5, as an implementation manner of the methods shown in the above figures, the present disclosure provides some embodiments of an apparatus for acquiring video stream data.

Here, the determination unit 501 is configured to determine whether the equipment room identifier of the equipment room where the pull stream data packet is received is the same as the target equipment room identifier included in the connection identifier in the pull stream data packet in response to receiving the pull stream data packet transmitted from the target terminal. The pull stream data packet is generated when the target terminal plays a video stream, and the target equipment room identifier is the equipment room identifier of the equipment room where the first pull stream data packet generated when the target terminal plays the video stream is received. The transfer unit 502 is configured to transfer the pull stream data packet to the target communication 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 equipment room where the pull stream data packet is received. The acquisition unit 503 is configured to acquire video stream data through the target communication equipment room.

[0087] In an optional embodiment of some embodiments, the acquisition unit 503 includes a first acquisition sub-unit and a second 2 acquisition sub-unit (not shown).
