Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0047] Embodiment 1:

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

[0049] Step S1: The access service receives an access request sent by the smart device corresponding to the service instance, wherein the access request carries at least device information and access status of the smart 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), belonging ID (IDENTITY DOCUMENT) C_ID (IDENTITY DOCUMENT), belonging machine ID, instance status, whether enabled, instance version, instance tag, instance load, instance weight, and 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, and instance weight; the scheduling strategy includes calculating streaming media service instances, streaming media service instance load, and instance port management method.

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

[0052] Step S3: the real-time computing service monitors the access information of the smart device in real time, and allocates port weights based on the access information and in accordance with a preset port model, where the preset port model is a port configuration strategy preset by the terminal user of the smart device based on business scenario needs;

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

[0054] The media management service dynamically loads streaming media service instances and ports based on a preset field model and in accordance with the assigned port weights; wherein,

[0055] The port includes at least one of an instance ID, a port range start value, a port range end value, a port category, a port purpose, an instance load, and an instance weight.

[0056] Of course, the preset field model may also include at least one of the following fields: instance ID, belonging IDC_ID, belonging machine ID, instance status, whether enabled, instance version, instance tag, instance load, instance weight, and audit field.

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

[0058] Based on the port weights allocated by the real-time computing service, the media management service dynamically loads streaming media service instances and ports in a chain queue manner.

[0059] Configure the port policy as follows, including:

[0060] Obtain the streaming media service instance information and port information to be loaded, and initialize the port information;

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

[0062] The port policy is configured in the following manner, further comprising:

[0063] When a port is added, the element is placed at the position pointed to by the tail marker, and the tail marker is moved down one position;

[0064] When a port is applied for, the port at the head of the queue is set to an empty position, and the head of the queue is moved down to the next port.

[0065] When the port is returned for use, the returned port is placed at the end of the queue, and the end marker moves down to the next position. When the current port queue is full, determine whether there is an empty position at the head: if there is no empty position, start the port queue expansion; if there is an empty position, the port queue forms a circular queue, and the end and head of the queue start the port queue expansion when the queue is full, and the end marker moves to the position where the queue size is plus one.

[0066] Step S4: The media management service dynamically loads the streaming media service instance and port based on the port weight assigned by the real-time computing service.

[0067] Streaming media services have extremely high demands on bandwidth resources, especially when a large number of clients access the service at the same time, which will put tremendous 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. Streaming media multi-port management technology dynamically starts multiple ports through streaming media services and uses multi-port intelligent management algorithms, so that smart terminals can establish different network connections to achieve grouping and independent access.

[0068] Improve the reliability and stability of streaming media services. Streaming media services can provide services on multiple ports simultaneously, ensuring that even if a port fails or is congested, other ports can still work normally, providing users with continuous and stable streaming media services.

[0069] Enhance the scalability of streaming services. As the number of users grows and the demand increases, streaming services need to be able to quickly expand their service capabilities. Multi-port management enables streaming services to flexibly add new ports to meet more concurrent requests and higher bandwidth requirements.

[0070] By optimizing resource allocation and load balancing, streaming media services can allocate server resources more intelligently and distribute different requests to different ports for processing, thereby achieving load balancing. This can not only improve server utilization, but also reduce the load pressure of a single port, avoiding service interruption or performance degradation due to overload of a single port.

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

[0072] Enhance the security and privacy protection of streaming media services. Through multi-port management, streaming media services can implement more stringent security policies and access control mechanisms. For example, different ports can be configured with different security levels and access rights to ensure that only authenticated and authorized users can access specific streaming media content. This not only protects the copyright and privacy of streaming media content, but also prevents unauthorized access and malicious attacks.

[0073] Supporting more application scenarios and business needs, streaming media services have been widely used in video on demand, live broadcast services, 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, thereby providing users with a richer and more personalized experience.

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

[0075] Embodiment 2:

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

[0077] Step S1: The access service receives an access request sent by the smart device corresponding to the service instance, wherein the access request carries at least device information and access status of the smart 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 policy in real time and sends it to the real-time computing service, and calculates the access point of the smart device based on the loaded scheduling policy;

[0079] Among them, the core fields of the streaming media instance include instance ID (IDENTITY DOCUMENT, ID card identification number), belonging ID, C_ID (IDENTITY DOCUMENT, ID card identification number), belonging machine ID, instance status, whether enabled, instance version, instance tag, instance load, instance weight, audit field and other fields; the core fields of the streaming media instance multi-instance port 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, such as Figure 2 shown.

[0080] Step S3: the real-time computing service monitors the access information of the smart device in real time, and allocates port weights based on the access information and in accordance with a preset port model, where the preset port model is a port configuration strategy preset by the terminal user of the smart device based on business scenario needs;

[0081] Streaming media instance scheduling process: The media service management dynamically loads media service instances and instance ports, and the real-time computing service calculates the number of accesses, load and other dimensional data of each service instance in real time. Considering the scaling of resource pools and nodes, the dynamic scaling of streaming media instances uses a chain queue, because the advantage of the chain is that it is very convenient to add and delete new streaming media instance nodes. However, the chain needs to dynamically allocate memory when adding nodes, which is a relatively resource-consuming and time-consuming process. If the number of instances is fixed and you want to have higher performance, you can use a queue with a sequential representation method. The streaming media instance screening process is as follows: In the initial state, an initial weight is set for each streaming media instance. The real-time computing service obtains the statistical data of various dimensions of each instance, labels the instance, and the scheduling module performs chain sorting according to the specified strategy. The sorting is not reflected in the weight value sorting, but in a chain manner. Each element stores the address of its previous and next elements. Each time the sorting is changed, you only need to change the pointing of the corresponding streaming media instance node. Advantages: Few changes, no consideration of performance issues caused by too many changes, see for details Figure 3 .

[0082] The algorithm above implements the specified policy streaming instance screening, and further screening and management of the streaming instance port is required. The streaming instance provides different instance port ranges for exclusive / shared use according to the protocol, and the instance ports need to be grouped and managed. See the model relationship for details. Figure 4 .

[0083] After grouping, screening is performed according to the strategy. The specific process is as follows Figure 5After the service starts loading the streaming media instance information and instance port information, the instance port information is initialized. When the array is empty, the head of the team is represented by begin and the tail of the team is represented by next. The head of the team and the tail of the team point to the same position (where the array is 0), that is, when the head of the team == the tail of the team, the queue is empty. The size is the maximum total number of instance ports provided by the protocol after the loaded grouping. When an instance port is added, it is placed in the position of the tail of the team, and the tail of the team moves down; when the instance port is applied for, the current position of the head of the team is empty, and the head of the team moves down to the next instance port. When the instance port is returned for use, it is placed at the next position at the end of the queue. The next position at the end of the queue moves down to the next position. If it cannot move, it means that the current instance port queue is full. In this case, it is determined whether there is any empty position at the head. If not, it is necessary to start the instance port queue expansion. If there is any empty position at the front, the instance port queue forms a circular queue. When the next+1 at the end of the queue = the begin at the head of the queue, it means that the queue is full. It is necessary to start the instance port queue expansion and move the next position at the end of the queue to the position of size+1.

[0084] The chain queuing method includes: after obtaining the loaded streaming media service instance information and instance port information, initializing the instance port information, when the array is empty, the head of the queue is marked with the head begin and the tail of the queue is marked with the tail next; when the head begin and the tail next point to the same position, that is, the head begin == the tail next, the queue is empty, and the size size is the maximum total number of instance ports provided by the protocol after the grouping is loaded; when an instance port is added, the element is placed in the position pointed to by the tail next, and the tail next moves down one position; when the instance port is applied for, the head b The current position of egin is set to empty, and the begin position of the queue is moved down to the next instance port; when the instance port is returned for use, it is placed at the next position of the queue, and the next position of the queue is moved down to the next position. If it cannot move, it means that the current instance port queue is full, then it is determined whether there is any empty position at the head. If not, it is necessary to start the instance port queue expansion; if there is any empty position at the front, the instance port queue forms a circular queue. When the next+1 of the queue tail = the begin of the queue head, it means that the queue is full, and it is necessary to start the instance port queue expansion, and the next position of the queue tail is moved to the position of size+1.

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