Multi-port management technology can meet the needs of high-quality, low-latency and strong-interactive audio and video services in these fields.

[0003] Traditional streaming media transmission methods require servers to handle a large number of point-to-point connections, which increases the load of the server and can cause performance bottlenecks. For this reason, the prior art provides various multi-port-based streaming media service management solutions, however, the existing multi-port management of streaming media services mainly focuses on how to improve the efficiency, stability and accessibility of streaming media transmission.

[0004] In fact, streaming media services have a very high demand for bandwidth resources, especially when a large number of clients access simultaneously, which can cause great pressure on network bandwidth.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0047] Embodiment 1

[0048] Referring to Figure 1 , a step flowchart of a video service multi-instance and multi-instance port scheduling method of the present application is shown, applied to a streaming media management service system with service instance management function, the streaming media management service system being used to provide access service, streaming media management service, scheduling service and real-time computing service; the streaming media service instance management function covers the life cycle of service instance from creation to termination, and the method comprises:

[0049] Step S1: the access service receives an access request sent by an intelligent device corresponding to the service instance, the access request at least carrying device information and an access state of the intelligent device, and sends the device information to the media management service and the scheduling service respectively;

[0050] The streaming media service instance includes instance ID (IDENTITY DOCUMENT, identity certificate identification number), home ID (IDENTITY DOCUMENT, identity certificate identification number) C_ID (IDENTITY DOCUMENT, identity certificate identification number), home machine ID, instance state, whether to enable, instance version, instance label, instance load, instance weight, audit field; the instance port includes instance ID, instance port range start value, instance port range end value, instance port category, instance port purpose, instance load, instance weight; the scheduling strategy includes computing the streaming media service instance, the streaming media service instance load, and the instance port management mode.

[0051] Step S2: the scheduling service loads the scheduling strategy in real time and sends it to the real-time computing service, and calculates the access point of the intelligent device based on the loaded scheduling strategy;

[0052] Step S3: the real-time computing service monitors the access information of the intelligent device in real time, and assigns port weight according to a preset port model based on the access information, the preset port model being a port configuration strategy preset by a terminal user of the intelligent device based on the needs of a business scenario;

[0053] The media management service dynamically loads the streaming media service instance and the port based on the port weight assigned by the real-time computing service, and the step comprises:

[0054] The media management service dynamically loads the streaming media service instance and the port based on the preset field model and according to the assigned port weight; wherein,

[0055] The port at least comprises one of the instance ID, the port range start value, the port range end value, the port category, the port use, the instance load, and the instance weight.

[0056] Of course, the preset field model can also at least comprise one of the instance ID, the home IDC ID, the home machine ID, the instance state, whether to enable, the instance version, the instance label, the instance load, the instance weight, and the audit field.

[0057] The media management service dynamically loads the streaming media service instance and the port based on the port weight assigned by the real-time computing service, and the step comprises:

[0058] The media management service dynamically loads the streaming media service instance and the port in a chain queue mode based on the port weight assigned by the real-time computing service.

[0059] The port strategy is configured in the following manner, which comprises:

[0060] The streaming media service instance information and the port information to be loaded are acquired, and the port information is initialized.

[0061] When the head identifier and the tail identifier point to the same position, it is determined that the queue from the head to the tail is an empty queue, and the queue size is the maximum port value provided by the used protocol after the loading group.

[0062] The port strategy is configured in the following manner, which further comprises:

[0063] When the port is newly added, the element is placed in the position pointed by the tail identifier, and the tail identifier is moved down by one position.

[0064] When the port is applied for use, the port at the current position of the head is set as an empty position, and the head identifier is moved down to the next port.

[0065] When the port is returned for use, the returned port is placed in the tail position, the tail identifier is moved to the next position, and when the current port queue is full, it is determined whether there is an empty position at the head: if there is no empty position, the port queue is expanded; if there is an empty position, the port queue forms a circular queue, and the tail and the head are moved to the position of the queue size plus one when the queue is full.

[0066] Step S4: The media management service dynamically loads the stream media service instances and ports based on the port weights assigned by the real-time computing service.

[0067] The demand for bandwidth resources by stream media services is extremely high, especially when a large number of clients access simultaneously, which can cause great pressure on network bandwidth. Different network interfaces (such as WiFi and LTE) have significant differences in bandwidth jitter, latency, etc., which increases the complexity and challenges of multi-path transmission technology. Stream media multi-port management technology dynamically starts multiple ports through stream media services, and multi-port intelligent management algorithms, so that intelligent terminals establish different network connections to achieve grouping and independent access.

[0068] To improve the reliability and stability of stream media services, stream media services can provide services on multiple ports simultaneously, so as to ensure that even if a port fails or is congested, other ports can still work normally, providing continuous and stable stream media services for users.

[0069] To enhance the scalability of stream media services, as the number of users and demand increases, stream media services need to quickly expand their service capabilities. Multi-port management enables stream media services to flexibly add new ports to meet more concurrent requests and higher bandwidth demands.

[0070] To optimize resource allocation and load balancing, stream media services can more intelligently allocate server resources and distribute different requests to different ports for processing, thereby achieving load balancing. This not only improves server utilization, but also reduces the load pressure on individual ports, avoiding service interruptions or performance degradation due to individual port overload.

[0071] To improve the flexibility and convenience of user access, users may be in different network environments or use different devices to access stream media services. Multi-port management enables stream media services to support more network protocols and device types, providing more flexible and convenient access methods, such as some ports may support HTTP protocol, while other ports may support RTSP or RTMP protocol to meet the needs of different users.

[0072] To enhance the security and privacy protection of stream media services, through multi-port management, stream media services can implement more stringent security policies and access control mechanisms, such as different ports can be configured with different security levels and access permissions to ensure that only authenticated and authorized users can access specific stream media content. This not only protects the copyright and privacy of stream media content, but also prevents unauthorized access and malicious attacks.

[0073] Support more application scenarios and business needs, streaming media services have been widely used in video on demand, live service, distance education, security monitoring and other fields. Multi-port management enables streaming media services to support more application scenarios and business needs, such as supporting high-definition video transmission, multi-screen interaction, intelligent recommendation and other functions, so as to provide users with more rich and personalized experience.

[0074] In summary, the multi-port management method of streaming media service can improve the reliability, stability, scalability, resource allocation efficiency, user access flexibility and security of streaming media service, and support more application scenarios and business needs.

[0075] Embodiment 2:

[0076] As shown in Figure 6 The application provides a video service multi-instance and multi-instance port scheduling method, which realizes the scheduling and task distribution of intelligent terminal access requests through streaming media instance management, instance port management and scheduling, and realizes the intelligent scheduling of video service multi-instance and multi-instance port: applied to a streaming media management service system with service instance management function, the streaming media management service system is used to provide access service, streaming media management service, scheduling service and real-time computing service; the streaming media service instance management function covers the life cycle from creation to termination of the service instance, and the specific method includes:

[0077] Step S1: The access service receives the access request sent by the intelligent device corresponding to the service instance, and the access request at least carries the device information and the access state of the intelligent device, and sends the device information to the media management service and the scheduling service respectively;

[0078] Step S2: The scheduling service loads the scheduling strategy in real time and sends it to the real-time computing service, and calculates the access point of the intelligent device based on the loaded scheduling strategy;

[0079] Among them, the core fields of the streaming media instance include instance ID (IDENTITY DOCUMENT, identity identification number), home ID, C_ID (IDENTITY DOCUMENT, identity identification number), home machine ID, instance state, whether to enable, instance version, instance label, instance load, instance weight, audit field and other fields; The core fields of the multi-instance port of the streaming media instance include instance ID, instance port range start value, instance port range end value, instance port category, instance port purpose, instance load, instance weight and other fields, as shown in Figure 2

[0080] ​Step S3: The real-time computing service monitors the access information of the intelligent device in real time, and assigns port weights based on the access information and according to a preset port model, which is a port configuration strategy preset by a terminal user of the intelligent device based on the needs of a business scenario;

[0081] The media service manages dynamic loading of media service instances and instance ports, and the real-time computing service calculates the access number, load and other dimensional data of each service instance in real time. Considering the scalability of resource pools and nodes, the chain queue is adopted for dynamic scaling of the media service instances, because the chain queue can conveniently add and delete new media service instance nodes. However, the chain queue needs to dynamically allocate memory when adding nodes, which is a resource- and time-consuming process. If the instance number length is fixed and high performance is required, a queue in a sequential representation manner can be used. The media service instance screening process is as follows: an initial weight is set for each media service instance in the initial state, the real-time computing service obtains the statistical data of various dimensions of each instance, the instances are labeled, and the scheduling module sorts the instances in a chain manner according to the specified strategy. The sorting is not reflected by the value of the weight, but by the chain manner, in which each element stores the addresses of the previous and next elements. Each time the sorting is changed, only the pointers of the corresponding media service instance nodes need to be changed. Advantage: less change, and no performance problem caused by too many changes. For details, see Figure 3 .

[0082] The above algorithm realizes the screening of media service instances according to the specified strategy, and further screening and management of the media service instance ports are required. According to the protocol, the media service instances provide different instance port ranges in a dedicated / shared manner, and the instance ports need to be managed in groups. For details, see Figure 4 .

[0083] After grouping, the instance ports are screened according to the strategy. For details, see Figure 5, the service starts loading the stream media instance information and instance port information, and the instance port information is initialized. When the array as a whole is empty, the head of the queue is marked by begin, and the tail of the queue is marked by next. The head of the queue and the tail of the queue point to the same position (the place where the array is 0). When the head of the queue == the tail of the queue, the queue is empty. The size is the maximum instance port total value provided by the protocol after loading the group. When an instance port is added, the element is placed in the position pointed to by the tail of the queue next, and the tail of the queue next is moved down. When the instance port is applied, the current position of the head of the queue is empty, and the head of the queue is moved to the next instance port. When the instance port is returned, it is placed in the position pointed to by the tail of the queue next, and the tail of the queue next is moved to the next position. If it cannot be moved, it means that the current instance port queue is full. Then it is judged whether there is a free position at the head. If there is no free position, the instance port queue needs to be expanded. If there is a free position in front, the instance port queue forms a circular queue. When the tail of the queue next + 1 == the head of the queue begin, it means that the queue is full, and the instance port queue needs to be expanded. The tail of the queue next is moved to the size + 1 position.

[0084] The method of the chain queue includes: obtaining loaded stream media service instance information and instance port information, and initializing the instance port information. When the array as a whole is empty, the head of the queue is marked by begin, and the tail of the queue is marked by next. When the head of the queue == the tail of the queue, the queue is empty. The size is the maximum instance port total value provided by the protocol after loading the group. When an instance port is added, the element is placed in the position pointed to by the tail of the queue next, and the tail of the queue next is moved down. When the instance port is applied, the current position of the head of the queue is empty, and the head of the queue is moved to the next instance port. When the instance port is returned, it is placed in the position pointed to by the tail of the queue next, and the tail of the queue next is moved to the next position. If it cannot be moved, it means that the current instance port queue is full. Then it is judged whether there is a free position at the head. If there is no free position, the instance port queue needs to be expanded. If there is a free position in front, the instance port queue forms a circular queue. When the tail of the queue next + 1 == the head of the queue begin, it means that the queue is full, and the instance port queue needs to be expanded. The tail of the queue next is moved to the size + 1 position.

[0085] Step S4: The media management service dynamically loads the stream media service instance and port based on the port weight allocated by the real-time computing service.
