[0023] The example embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0024] Example environment

[0025] FIG. 1 shows a schematic diagram of an example environment 100 in which embodiments of the present disclosure can be implemented. As shown in FIG. 1, the example environment 100 can include an electronic device 110, a master server 120, a CDN (Content Delivery Network) server 130, an edge server 140, and a terminal device 150.

[0026] In the environment 100 of FIG. 1, the electronic device 110 can receive a transmission parameter reported from the edge server 140, which can include, for example, throughput and / or packet loss rate. Further, the electronic device 110 can evaluate the service capacity of the edge server 140 based on the transmission parameter of the edge server 140. After evaluating the service capacity of the edge server 140, the electronic device 110 can push a data stream such as a live stream to the edge server 140 via the CDN server 130 to instruct the edge server 140 to provide service to at least one terminal device 150.

[0027] In the environment 100 of FIG. 1, the main server 130 can acquire a data stream sent by the terminal device 150 and push the data stream to the CDN server to instruct the CDN server to push the data stream to other terminal devices via the edge server 140.

[0028] In some embodiments, the electronic device 110 communicates with the edge server 140 to instruct the edge server 140 to determine the service capacity of the service serving the corresponding terminal device 150. The electronic device 110 can be a standalone physical server, a server cluster or a distributed system composed of multiple physical servers, a cloud server providing basic cloud computing services such as cloud service, cloud database, cloud computing, cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, content distribution network, and big data and artificial intelligence platform, etc. The electronic device 130 can include, for example, a computing system / server such as a mainframe, an edge computing node, a computing device in a cloud environment, etc.

[0029] The terminal device 110 can be any type of mobile terminal, fixed terminal, or portable terminal including a mobile handset, a desktop computer, a laptop computer, a notebook computer, a subnotebook computer, a netbook computer, a tablet computer, a media player, a multimedia player, a palmtop computer, a portable gaming terminal, a VR / AR device, a Personal Communication System (PCS) device, a personal navigation device, a Personal Digital Assistant (PDA), an audio / video player, a digital camera / camcorder, a positioning device, a television receiver, a radio broadcast receiver, an electronic book device, a game device, or any combination thereof, including accessories and peripherals of these devices, or any combination thereof. In some embodiments, the terminal device 110 can also support any type of interface to the user (such as "wearable" circuitry, etc.).

[0030] It should be understood that the structure and function of the various elements in the environment 100 are described for illustrative purposes only, without implying any limitation on the scope of the present disclosure.

[0031] Some example embodiments of the present disclosure will be hereinafter described with continuous reference to the drawings.

[0032] Example process

[0033] FIG. 2 shows a flowchart of a process 200 of service capacity determination of a service, according to some embodiments of the present disclosure. The process 200 can be implemented at the electronic device 110. The process 200 will be described below with reference to FIG. 1.

[0034] As shown in FIG. 2, at block 210, the electronic device 110 obtains service quality and service capacity of the service in a plurality of historical periods, respectively. The service capacity in each of the historical periods is different; the service quality in each of the historical periods is determined according to a set of transmission parameters in the historical period; and the service capacity in each of the historical periods is determined by applying a preset adjustment mode to a preset base service capacity, and the adjustment mode corresponding to each of the historical periods is different. In some embodiments, the service provided by the electronic device 110 can be a live service, for example.

[0035] As an example, the service quality can be a quality indicator of the live service, such as smoothness, clarity, etc. The service capacity can be the number of viewers who can simultaneously watch the live service, for example.

[0036] In some embodiments, the service capacity can indicate the number of concurrent users connected to the edge server associated with the service, for example. The number of concurrent users, i.e., the service capacity, can be represented using “quota”, for example. In some scenarios, the service capacity can be the number of terminal devices that the edge server 140 needs to provide the live service, for example.

[0037] In some embodiments, before obtaining the service quality and the service capacity of the service in the plurality of historical periods, respectively, the electronic device 110 can provide the service based on an initial service capacity in a first period. In some scenarios, the electronic device 110 can assign an initial number of concurrent users to the edge server 140 to instruct the edge server 140 to provide a number of live services corresponding to the number of concurrent users.

[0038] Further, the electronic device 110 can increase the service capacity of the service in at least one period after the first period until the service quality in the current period is lower than or equal to the service quality in the last period.

[0039] As an example, the "utility" can be the quality of service of the current period, and the "utility last" can be the quality of service of the last period, for example. The electronic device 110 can first set an initial service capacity for the edge server 140. For example, the "quota" can be assigned a value of 1 when the edge server 140 sets the initial service capacity. Further, the electronic device 110 can increase the "quota" by 2 times until the "utility" is not greater than the "utility last".

[0040] In some embodiments, the adjustment mode can be an increase service capacity mode (i.e., the first adjustment mode), a decrease service capacity mode (i.e., the second adjustment mode), and a maintain service capacity mode (i.e., the third adjustment mode). Each adjustment mode corresponds to a different period, the increase service capacity mode corresponds to the second period, the decrease service capacity mode corresponds to the third period, and the maintain service capacity mode corresponds to the fourth period.

[0041] As an example, the first adjustment mode can be referred to as "quota*ω", for example, to indicate that the service capacity should be increased. The second adjustment mode can be referred to as "quota*0", for example, to indicate that the server capacity should be decreased. The third adjustment mode can be referred to as "quota*1", for example, to indicate that the current server capacity should be maintained.

[0042] In some embodiments, the electronic device 110 can obtain a plurality of sets of transmission parameters corresponding to a plurality of historical periods, the transmission parameters including throughput and / or packet loss rate. For example, the electronic device 110 can obtain the transmission parameters in the second period corresponding to the increase service capacity strategy. Further, the electronic device 110 can determine the quality of service information corresponding to a plurality of periods based on the plurality of sets of transmission parameters.

[0043] As an example, the quality of service information can be calculated based on the following formula: utility = throughput * sigmoid(loss - 0.1) - alpha * throughput * loss

[0044] where "throughput" is the throughput, "loss" is the packet loss rate, "sigmoid" is a normalization function, and "alpha" is an adjustable parameter.

[0045] ​Further, the electronic device 110 can calculate the service quality information corresponding to the plurality of periods respectively based on the above formula. The service quality information corresponding to the second period associated with the first adjustment mode can be, for example, "utility first", the service quality information corresponding to the third period associated with the second adjustment mode can be, for example, "utility second", and the service quality information corresponding to the fourth period associated with the third adjustment mode can be, for example, "utility third".

[0046] At block 220, the electronic device 110 determines a target adjustment mode from the plurality of preset adjustment modes based on the service quality of the service in the plurality of historical periods, the service quality of the historical period corresponding to the target adjustment mode being greater than a preset quality threshold. As an example, after determining the service quality corresponding to different periods, the electronic device 110 can determine the target adjustment mode based on the numerical size of the service quality information corresponding to different periods. The plurality of preset adjustment modes include an adjustment mode for increasing the service capacity, an adjustment mode for reducing the service capacity, and an adjustment mode for keeping the current service capacity unchanged.

[0047] In some embodiments, the electronic device 110 can determine the target adjustment mode corresponding to the highest service quality from the plurality of preset adjustment modes based on the service quality.

[0048] As an example, after obtaining the service quality information corresponding to different adjustment modes, the electronic device 110 can judge the size of "utility first", "utility second" and "utility third", and select the adjustment mode associated with the largest service quality information as the target adjustment mode. For example, "utility first" is the largest service quality information, then the first adjustment mode is selected as the target adjustment mode.

[0049] At block 230, the electronic device 110 adjusts the basic service capacity of the service based on the target adjustment mode to determine the target service capacity of the service in the target period.

[0050] As an example, after determining that the target adjustment mode is completed, the electronic device 110 can continue to adjust the service capacity of the service based on the direction corresponding to the target adjustment mode. For example, the electronic device 110 can continue to increase the service capacity of the service until the service quality of the current period is lower than the service quality of the last period.

[0051] In some scenarios, the number of concurrent users of the edge server 140 can reach the maximum value when the service quality of the service is maintained. By continuously increasing the service capacity of the service, the maximum service capacity of the edge server 140 can be found more accurately.

[0052] Overall, the processing flow can include:

[0053] An initialization phase, in which the electronic device 110 can set the initial service capacity to 1 and set the service quality of the last period to a negative number.

[0054] A start-up phase, in which the electronic device 110 can compare the current service quality with the service quality of the last period. If the current service quality is greater than the service quality of the last period, the service capacity is increased. If the current service quality is not greater than the service quality of the last period, the detection phase is entered.

[0055] A detection phase, in which the electronic device 110 can determine the sizes of the service qualities corresponding to the second period, the third period, and the fourth period. If the service quality corresponding to the second period is the largest, a preset first adjustment mode is used as the target adjustment mode. If the service quality corresponding to the third period is the largest, a preset second adjustment mode is used as the target adjustment mode. If the service quality corresponding to the fourth period is the largest, a preset third adjustment mode is used as the target adjustment mode. After the electronic device 110 determines the adjustment mode, the moving phase can be entered.

[0056] A moving phase, in which the electronic device 110 can determine the sizes of the current service quality and the service quality of the last period. If the current service quality is greater than the service quality of the last period, the service capacity is adjusted based on the target adjustment mode. If the current service quality is not greater than the service quality of the last period, the detection phase can be entered again to adjust the service capacity of the service in real time.

[0057] In this way, the embodiments of the present disclosure can dynamically adjust the service capacity, thereby fully utilizing the service resources.
