[0031] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0032] The video transmission link establishment method provided in the embodiments of the present application can be applied to, for example, Figure 1The system architecture is shown. Among them, the live client can send the request information of the video data needing to be played to the video service platform, and the user plane data forwarding gateway communicates with the video service platform through the network. The user plane data forwarding gateway first receives the video request sent by the video service platform in the HTTPS signaling mode, including the address information and the supported transmission protocol information of the video source end and the video playback end, and then sends a message carrying the obtained address information and transmission protocol information to the SRv6 controller. Then, the SRv6 controller determines the end-to-end transmission path from the video source end to the video playback end, and after determining the end-to-end transmission path that meets the preset condition, sends a corresponding encapsulation message to the edge SRv6 service access network element. The encapsulation message is used to instruct the edge SRv6 service access network element to encapsulate the video stream of the video source end, so that the encapsulated video stream is adapted to the SRv6 transmission on the bearer network according to the end-to-end transmission path. The user plane data forwarding gateway also receives the link establishment result message returned by the SRv6 controller for the end-to-end transmission path and returns the link establishment result to the video service platform in the HTTPS signaling mode.

[0033] In some embodiments of the present disclosure, the user plane data forwarding gateway is also referred to as an SGW service gateway, and the video service platform is also referred to as a VCP platform.

[0034] Among them, the video service platform can be realized by an independent server or a server cluster composed of multiple servers.

[0035] In one embodiment, as shown in Figure 2 , a video transmission link establishment method is provided. Taking the user plane data forwarding gateway in Figure 1 as an example, the method includes the following steps:

[0036] S201, the user plane data forwarding gateway receives the video request sent by the video service platform in the HTTPS signaling mode, and identifies the address information and the supported transmission protocol information of the video source end and the video playback end carried in the video request.

[0037] The video service platform sends a video request to the user plane data forwarding gateway in the HTTPS signaling mode. HTTPS is a secure transmission protocol for secure communication over computer networks. HTTPS communicates via HTTP, but uses SSL / TLS to encrypt data packets. Therefore, sending a video request in the HTTPS signaling mode can ensure the security and integrity of the data to some extent.

[0038] In the present disclosure, after the video service platform sends a video request to the user plane data forwarding gateway in an HTTPS signaling manner, the user plane data forwarding gateway can parse the video request to obtain key information therein, which at least includes address information and supported transmission protocol information of the video source end and the video playback end.

[0039] In S202, the user plane data forwarding gateway sends a message carrying the address information and the transmission protocol information to the SRv6 controller. The message is used to instruct the SRv6 controller to determine an end-to-end transmission path from the video source end to the video playback end. After determining an end-to-end transmission path that meets the preset condition, the SRv6 controller sends a corresponding encapsulation message to the edge SRv6 service access network element. The encapsulation message is used to instruct the edge SRv6 service access network element to encapsulate the video stream of the video source end, so that the encapsulated video stream is adapted to the SRv6 transmission on the end-to-end transmission path on the bearer network.

[0040] The SRv6 controller described above is a network device of a bearer network. In the present disclosure, it is responsible for determining an end-to-end transmission path from the video source end to the video playback end according to the chain building policy request received from the SGW service gateway, and instructing the edge SRv6 service access network element to encapsulate the video stream of the video source end.

[0041] The SRv6 controller sending a corresponding encapsulation message to the edge SRv6 service access network element means that if there is a path that meets the constraint condition, the SRv6 controller issues the configuration of the related network elements on the SRv6 path. The issuance can be understood as the SRv6 controller issuing the configuration to the network element 1, the network element 2, and the network element N of the bearer network according to its network model. The network element refers to a set of network elements related to the establishment of the service link in the bearer network, which can be one or multiple. The SRv6 controller specifically issues the chain building information to which network elements, and the actual model and path selection of the service link are used as the criterion.

[0042] It can be understood that if the user plane data forwarding gateway further obtains other information carried in the video request of the VCP platform in step S201, the end-to-end transmission path from the video source end to the video playback end can also be comprehensively determined from the other information carried in the video request in step S202.

[0043] In S203, a link establishment result message returned by the SRv6 controller for the end-to-end transmission path is received.

[0044] The link establishment result message described above contains the results of successful chain building and the results of failed chain building. Therefore, the link establishment result message returned by the SRv6 controller can be a chain building success message or a chain building failure message.

[0045] In the present disclosure, after receiving the link establishment result message returned by the SRv6 controller, the user plane data forwarding gateway parses the message, obtains information about whether the link establishment is successful according to the parsing result, and performs corresponding processing.

[0046] Specifically, the user plane data forwarding gateway can check the status field in the link establishment result message to determine whether the link establishment is successful. If the link establishment is successful, the SRv6 controller returns the link information to the video service platform; if the link establishment fails, the user plane data forwarding gateway performs error processing, such as sending an error message to the video service platform to prompt the reason for the link establishment failure and performing corresponding error processing.

[0047] S204, sending the link establishment result to the video service platform in an HTTPS signaling manner.

[0048] After the link establishment result message processing is completed, the user plane data forwarding gateway sends the link establishment result to the video service platform. Here, the message is sent in an HTTPS signaling manner to ensure security and reliability.

[0049] Specifically, the user plane data forwarding gateway constructs a link establishment result message and sends the message to the video service platform through the HTTPS protocol. The message contains the result information of the link establishment, such as the status of successful or failed link establishment and corresponding error information.

[0050] After receiving the link establishment result returned by the user plane data forwarding gateway, the video service platform can perform corresponding processing according to the result. If the link establishment is successful, the video service platform can return corresponding prompt information to the video playback end (or video request end), such as please wait while the video is loading; if the link establishment fails, the video service platform can take corresponding measures, such as reinitiating a link establishment request to the user plane data forwarding gateway or performing other error processing.

[0051] In the video transmission link establishment method of the above embodiment, the user plane data forwarding gateway receives the video request sent by the video service platform in an HTTPS signaling manner, identifies important information in the video request, and sends the identified important information to the SRv6 controller to instruct the SRv6 controller to determine a transmission path of the video that meets the preset condition and perform subsequent encapsulation of the video stream by the edge SRv6 service access network element, so that the encapsulated video stream is adapted to the bearer network and transmitted according to the corresponding end-to-end transmission path through SRv6. Thus, a cooperative transmission method between the application layer and the underlying network based on HTTPS is constructed, and efficient cooperation between the bearer network and the application layer network is achieved.

[0052] In an embodiment, before the user plane data forwarding gateway sends the address information and the transmission protocol information to the SRv6 controller, the following steps can be included:

[0053] Step 1: The user plane data forwarding gateway verifies the credibility of the video service platform.

[0054] The credibility to be verified includes verifying whether the video request sent by the video service platform in the HTTPS signaling mode carries the HTTPS certificate pre-issued by the user plane data forwarding gateway. Specifically, it can be detected whether there is certificate information in the video request. If there is, further query the related information of the certificate in the white list of the domain. If there is, it indicates that the certificate carried in the video request is the HTTPS certificate pre-issued by the gateway, and then it is determined that the credibility of the video service platform conforms to the specification. If the video request does not carry certificate information, or the certificate information carried does not exist in the white list of the domain, that is, the verification result is no, then the credibility of the video service platform does not conform to the specification. In this case, the user plane data forwarding gateway does not issue policies to the SRv6 controller, but feeds back the information that the video request does not conform to the specification to the video service platform.

[0055] The above-mentioned credibility verification method of the video service platform can be a white list mechanism. The white list mechanism specifically refers to that the mutual trust relationship between the video service platform and the user plane data forwarding gateway is pre-configured in the domain, and only the resources configured in the system can interwork and intertrust. The mutual trust relationship includes but is not limited to the HTTPS certificate in the above-mentioned example.

[0056] Step 2: In the case where the credibility of the video service platform conforms to the specification, the user plane data forwarding gateway queries the service level pre-signed by the video service platform, and obtains the transmission constraint information corresponding to the service level.

[0057] The pre-signed service level can be the bandwidth, delay, service duration and service period agreed in the contract when the customer (video service platform or video playback end user) signs up, which will be recorded in the domain system, and the user plane data forwarding gateway will perform configuration and issue according to the record in the future.

[0058] In the above-mentioned embodiment, the message sent by the user plane data forwarding gateway to the SRv6 controller can include: the user plane data forwarding gateway sends transmission policy information to the SRv6 controller, and the transmission policy information carries the address information, the transmission protocol information and the transmission constraint information of the video source end and the video playback end respectively. The transmission policy information is used to instruct the SRv6 controller to determine an end-to-end transmission path from the video source end to the video playback end and conforming to the transmission constraint information.

[0059] The embodiment sends a message carrying transmission constraint information to the SRv6 controller through the user plane data forwarding gateway, improves the accuracy of network video end-to-end transmission path selection, and provides different customers with corresponding transmission paths and transmission quality, for example, for high-level customers, the delay of video transmission can be reduced, and the video stuttering and loading time can be reduced.

[0060] Further, in one embodiment, the HTTPS request header information carried in the information carried in the video request sent by the video service platform in the HTTPS signaling mode includes:

[0061] One: IP address of the video source end and IP address of the video playback end.

[0062] Two: Transmission protocol and port information of the IPv6 format supported by the video source end and the video playback end.

[0063] Three: Video transmission link state announcement of the transmission link.

[0064] The video transmission link state announcement includes the video transmission link state announcement of the video playback end, and the video transmission link state announcement includes bandwidth, delay, packet loss rate, and service type value of the IP packet header.

[0065] Specifically, the IP address of the video source end and the IP address of the video playback end are used to identify and locate the starting point and the end point of the video transmission. Providing these address information to the SRv6 controller can help determine the end-to-end transmission path.

[0066] Specifically, when determining the end-to-end transmission path, the transmission protocol and port information of the IPv6 format supported by the video source end and the video playback end need to be considered. These information can be used to guide the SRv6 controller to select appropriate transmission protocol and port, and realize efficient video transmission.

[0067] Among them, the bandwidth, delay, packet loss rate and service type value of the IP packet header in the video transmission link state announcement of the transmission link can inform the opposite end of the current link state of the sender, help the SRv6 controller to evaluate and select the optimal transmission path, to provide better video transmission quality, and avoid congested or unstable network environment when the SRv6 controller selects the transmission path, to optimize the utilization of network resources.

[0068] Through the above embodiment, by adding the key information of the video request to the HTTPS request header information, based on sending to the user plane data forwarding gateway using the HTTPS signaling mode, both efficient video transmission and communication security can be realized, and information tampering or theft can be prevented.

[0069] Further, in one embodiment, the user plane data forwarding gateway sends the link establishment result to the video service platform in an HTTPS signaling manner, including:

[0070] Case one: the user plane data forwarding gateway generates a path ID corresponding to the end-to-end transmission path in the case of receiving a link establishment success returned by the SRv6 controller for the end-to-end transmission path. Correspondingly, when the user plane data forwarding gateway sends the link establishment result to the video service platform in an HTTPS signaling manner, the path ID is carried in the HTTPS request header information. After sending the link establishment result to the video service platform in an HTTPS signaling manner, the user plane data forwarding gateway further includes: receiving an HTTPS chain dismounting request sent by the video service platform, parsing the HTTPS chain dismounting request to determine the path ID to be dismounted, and notifying the SRv6 controller to release the path resource corresponding to the path ID.

[0071] The path ID is an identifier for uniquely identifying the established transmission path, facilitating the management and identification of the path by other network elements. Specifically, the path ID is carried in the HTTPS request header, and the video service platform can identify and record the established transmission path, providing corresponding services in the subsequent video transmission process, such as providing different bandwidth, cache strategy or flow control according to the path ID.

[0072] Case two: the user plane data forwarding gateway generates a chain establishment failure error code in the case of receiving a link establishment failure returned by the SRv6 controller for the end-to-end transmission path. The chain establishment failure error code is used to identify the corresponding chain establishment failure reason. When the user plane data forwarding gateway sends the link establishment result to the video service platform in an HTTPS signaling manner, the chain establishment failure error code is carried in the HTTPS request header information.

[0073] Specifically, the chain establishment failure error code is an identifier for identifying different chain establishment failure reasons, such as network failure or resource shortage. The error code carried in the HTTPS request header information can help the video service platform identify the error code to determine the specific reason for the chain establishment failure, and take appropriate processing measures according to the need, such as reselecting the path or providing other solutions.

[0074] Through the above embodiments, the path ID is generated when the video transmission link is established successfully, which can uniquely identify and manage different end-to-end transmission paths, making the identification and management of the path more accurate and effective. The error code for the video transmission chain establishment failure is used to speed up the problem solving and processing process, thereby improving the reliability and stability of the video transmission.

[0075] In order to better understand the above video transmission link establishment process, the following is combined with Figure 1 and Figure 3The specific process of establishing a video transmission link of the application is illustrated in detail below.

[0076] S301, the live client initiates a live video playing request to the VCP platform.

[0077] S302, the VCP platform acquires the IP address and protocol information of the live server (i.e. video source end) and the client, and sends the service level (uplink and downlink bandwidth, QoS) required by the client to the SGW in the HTTPS mode, and the specific encapsulation of the request is as follows:

[0078] carrying the HTTPS certificate issued in advance by the SGW, initiating a service request, and carrying each item of information in the HTTPS link establishment request header information according to the following rules:

[0079] (1) X-Service SIP: y.y.y.y-24## y is the IP segment of the live server, multiple server segments can be filled in, and IPv6 format is supported, for example, 2208::0 / 96;

[0080] (2) X-Service DIP: x.x.x.x-24## x is the IP segment of the client, multiple client segments can be filled in, and IPv6 format is supported, for example, 2018::0 / 96;

[0081] (3) X-Service PD: TCP / UDP, port number# fill in the protocol and port information of the service;

[0082] (4) X-Service LSA: B = 1000; D = 100; L = 1; T = 3# B is the bandwidth, unit: Mbps; D is the delay, unit: millisecond; L is the packet loss rate, unit: ten thousandth of L; T is the TOS value of the IP header.

[0083] S303, the SGW service gateway verifies the credibility of the VCP, queries the subscribed service level, and if it meets the specifications, issues a policy request to the SRv6 controller.

[0084] S304, the SRv6 controller receives the policy request of the SGW, queries and calculates the end-to-end resources and path, and if there is a path that meets the constraint conditions, issues the configuration of the related network elements on the SRv6 path; if no path that meets the constraint conditions is calculated, returns the information of insufficient resources, link establishment rejection, etc. to the SGW.

[0085] S305, the edge SRv6 service access network element encapsulates the service chain for the current requested video stream after receiving the policy of the SRv6 controller, so that it can be transmitted on the SRv6 bearing network.

[0086] S306, the SGW is also responsible for receiving the information returned by the SRv6 controller whether the policy routing establishment is successful or not, and feeding back to the VCP platform. Specifically:

[0087] (1) When the SRv6 controller returns the configuration success, the SGW generates a UUID as a session ID and returns it to the VCP platform.

[0088] (2) When the SRv6 controller returns the configuration failure, the SGW returns the chain establishment failure error code information to the VCP platform.

[0089] S307, after the video transmission ends, the VCP platform also sends an HTTPS disconnection request to the SGW, and the SGW determines the path ID to be removed based on the analysis of the disconnection request and notifies the SRv6 controller to release the corresponding path resources.

[0090] After the video transmission ends, the request information can be carried in the HTTPS disconnection request header information sent by the VCP platform to the SGW according to the following rules:

[0091] (1) X-Session ID: uuid# is the session ID returned by the SGW gateway after the successful establishment of the connection.

[0092] Through the above embodiment, the application proposes a calling method for SRv6 trusted collaboration for video transmission link establishment, which can provide an interface for HTTPS video transmission and realize the random build and disassembly capability. Specifically, the SGW gateway HTTPS interface calling method is introduced to build a network link establishment mechanism that meets the requirements of live video quality and realizes the random build and disassembly, and based on the security mechanism of trusted calling of the bearer network, the efficient collaboration of the bearer network and the application layer network is effectively realized, which does not depend on the underlying protocol and does not increase the encryption and decryption calculation overhead of the path network element, and is a collaborative transmission method for building the application layer and the underlying network through the overlay-underlay collaborative mode.

[0093] In one embodiment, as shown in Figure 4 based on the same inventive concept, the application embodiment also provides a video transmission link establishment device for realizing the video transmission link establishment method described above, which comprises a request identification module 401, an information sending module 402, an information receiving module 403 and a link feedback module 404, wherein:
