The CDN system may include at least two nodes and servers. Wherein, each node of the at least two nodes can inform the server of its own storage capability when it registers with the server. The server can perform resource scheduling according to the storage capacity of each node. Taking node 1 and node 2 as examples, the server stores data 1 in node 1 according to the storage capacity of node 1; node 2 sends a request message to the server to obtain data 1; the server determines that the node closest to node 2 is node 1, and Data 1 is stored in node 1, and the server determines that node 1 is a source node that provides data 1; and, the server obtains data 1 by interacting with node 1, and sends the data 1 to node 2.

However, the source node supports not only the CDN service but also the Internet service. The CDN service of the source node and the Internet service share the upstream bandwidth resources of the source node. The more bandwidth resources the CDN service occupies, the less bandwidth resources the Internet service can use. This will cause network congestion and affect the Internet service of the source node.

The difference between the resources, so that the server can determine whether to request the first data from the first terminal according to the bandwidth resources of the CDN service. For example, when the bandwidth resources of the CDN service and the Internet service share the uplink bandwidth resources of the first terminal, the server determines whether to use the first terminal as the source node of the first data according to the bandwidth resources of the CDN service, so as to avoid occupation by the CDN service. The more bandwidth resources available for the first terminal, the less bandwidth resources available for the Internet service, and the resulting network congestion can ensure the normal Internet service of the first terminal.

Through the above design, the server can determine whether to use the first terminal as a source node for providing the first data according to the bandwidth resources available for the CDN service of the first terminal. For example, the bandwidth resources required for transmitting the first data are less than or equal to the bandwidth resources of the CDN service, indicating that the bandwidth resources available for the CDN service of the first terminal are sufficient to support the transmission of the first data, and it will not affect the normal operation of the first terminal. Therefore, the server can use the first terminal as a source node for providing the first data. For another example, the bandwidth resources required to transmit the first data are greater than the bandwidth resources of the CDN service, indicating that the bandwidth resources available for the CDN service of the first terminal are insufficient to support the transmission of the first data. If the first terminal insists on transmitting the first data, Then, the normal Internet access service of the first terminal will be affected, resulting in network congestion.

The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings in the following embodiments of the present application.

The CDN system is a strategically deployed system, which can solve the problem of slow response speed for users accessing websites due to small network bandwidth, large user visits, and uneven distribution of network points. The purpose of the CDN system is to add a new network architecture to the existing Internet, and to publish the content of the website to the "edge" of the network closest to the user, so that the user can obtain the desired content nearby and improve the user experience. The responsiveness of visiting websites.

FIG. 1 shows a schematic diagram of a CDN system to which this embodiment of the present application is applicable. As shown in FIG. 1 , the CDN system may include a server 110 and at least two nodes. The at least two nodes in FIG. 1 take an optical line terminal (OLT) 121, an OLT 122, an optical network terminal (ONT) 131, an ONT 132, an ONT 133, and an ONT 134 as examples. The ONT may communicate with the server 110 through the OLT. The OLT may act as an intermediary between the server 110 and the ONT. For example, the OLT may forward data received from the server 110 to the ONT as downstream data, and forward data received from the ONT to the server 110 as upstream data.

Exemplarily, the server 110 may be a cloud server, a global server load balance (GSLB) server, or a global scheduling server, etc. The specific implementation form of the server 110 is not limited in this embodiment of the present application. The server 110 can be used to realize resource allocation between different nodes, so as to ensure that the best node is used to serve the users closest to it, so as to ensure the quality of access. For example, the ONT (or OLT) informs the server 110 of its own storage capability, and then the server 110 can manage the storage capability of the ONT (or OLT). The ONT can support Internet services and CDN services. The OLT can also support Internet services and CDN services. For example, the server 110 can pre-store the data 1 in the ONT 131 according to the storage capability of the ONT 131. When another node requests the server 110 to obtain the data 1, the server can send a request message to the ONT 131 for obtaining the data 1, and the ONT 131 After receiving the request message, data 1 can be sent to the other node.

It can be understood that, FIG. 1 is an example and does not limit the CDN system to which the embodiments of the present application are applicable. For example, the CDN system may also include more OLTs or ONTs. For another example, the CDN system can be applied not only to the optical communication technical field shown in FIG. 1 , but also to the wireless communication technical field and the like. To facilitate understanding of the embodiments of the present application, the following description takes the CDN system shown in FIG. 1 as an example.

The following takes ONT 131 and ONT 133 as examples, and briefly introduces the current CDN service transmission process in conjunction with FIG. 2 .

S201-S202: The server 110 sends the data 1 to the ONT 131 through the OLT 121.

S203: ONT 131 stores data 1. For example ONT 131 may store data 1 locally.

S204-S205: The ONT 133 sends a request message for acquiring the data 1 to the server 110 through the OLT 122.

S206: The server 110 receives the request message for obtaining the data 1 from the ONT 133 through the OLT 122, and determines that the ONT 131 is the source node that provides the data 1.

Exemplarily, the server 110 may determine that the ONT 131 is the node closest to the ONT 133 and storing the data 1 according to a load balancing algorithm or the like. Further, the server 110 can determine that the ONT 131 is the source node that provides the data 1.

It should be noted that the source node in the embodiment of the present application may be understood as a node that provides services for other nodes in the CDN system. Taking Fig. 1 as an example, ONT 131 stores data 1, then ONT 131 can be the source node that provides data 1 for other nodes; OLT 122 stores data 2, then OLT 122 can also be the source node that provides data 2 for other nodes .

S207-S208: The server 110 sends a request message for acquiring the data 1 to the ONT 131 through the OLT 121.

S209-S212: The ONT 131 receives the request message for obtaining data 1 from the server 110 through the OLT 121, and sends the data 1 to the ONT 133 through the OLT 121, the server 110, and the OLT 122. So far, the transmission process of the CDN service ends.

In the process shown in FIG. 2, the server 110 can select the ONT 131 closest to the ONT 133 as the source node, so that the ONT 133 can obtain the required data nearby, which can improve the response speed of the user accessing the website. However, the source node not only supports CDN services, but may also support other services such as Internet services, and CDN services share uplink bandwidth resources with other services such as Internet services. For example, the more bandwidth resources the CDN service occupies, the less bandwidth resources the Internet service can use, which affects the normal Internet access service of the source node and causes network congestion. For another example, the bandwidth resources available for the CDN service of the source node are relatively tight, but the actual bandwidth resources required by the CDN service are more, which will also cause network congestion.

In view of this, an embodiment of the present application provides a scheduling method. In this method, the first terminal may send information about the bandwidth resources of the CDN service to the server. For example, the information about the bandwidth resources of the CDN service may include the uplink bandwidth resources and the bandwidth resources occupied by the Internet service, or may also include the CDN service. Service bandwidth resources. In this way, the server can determine the actual available bandwidth resources of the CDN service of the first terminal, and determine whether to use the first terminal as the source node for providing data according to the actual available bandwidth resources of the CDN service of the first terminal, so as to avoid the The more bandwidth resources occupied by the CDN service, the less bandwidth resources available for the Internet access service, which causes the problem of network congestion in the Internet access service of the first terminal, thereby ensuring the normal Internet access service of the first terminal.

It should be noted that, in the following embodiments, the steps performed by the terminal (eg, the first terminal or the second terminal) may also be specifically performed by a module or component inside the terminal (eg, the first terminal or the second terminal), such as It can be executed by a chip or a chip system in the terminal (such as the first terminal or the second terminal); the steps executed by the server can also be executed by a module or component inside the server, for example, it can be executed by a chip or chip in the server. System execution; this is not limited in this embodiment of the present application.

FIG. 3 shows a schematic flowchart of a scheduling method provided by an embodiment of the present application. This method can be applied to the CDN system shown in FIG. 1 . The first terminal may be the ONT or OLT in FIG. 1 , the second terminal may be the ONT or OLT in FIG. 1 other than the first terminal, and the server may be the server 110 in FIG. 1 . As shown in FIG. 3 , the flow of the method can be as follows.

S301: The first terminal determines uplink bandwidth resources and bandwidth resources occupied by Internet access services.

Exemplarily, the first terminal stores the first data requested to be acquired by the second terminal. The first data may be video data, audio data, or pictures, etc. The specific form of the first data is not limited in this embodiment of the present application. For example, when the first terminal registers with the server, it may register information such as its own internet protocol (IP) address and storage capability to the server, so that the server can manage the storage capability of the first terminal. Further, the first terminal may acquire and store the first data by sending a request message for acquiring the first data to the server; or, the first terminal may receive and store the first data actively pushed from the server. For example, the server may push the video data of the hot program to the first terminal according to the storage capability of the first terminal.

The first terminal may be an ONT or an OLT. The second terminal may be an ONT or an OLT. Taking the CDN system shown in FIG. 1 as an example, the first terminal and the second terminal may be two ONTs under the same OLT, for example, the first terminal is ONT 131, and the second terminal is ONT 132; The second terminal may also be two ONTs under different OLTs, for example, the first terminal is ONT 131, and the second terminal is ONT 134; or, both the first terminal and the second terminal may be OLTs, such as the first terminal is OLT 121 , the second terminal is OLT 122; or, the first terminal may be an ONT, and the second terminal may be an OLT, for example, the first terminal is ONT 131, and the second terminal is OLT 121; The terminal may be an ONT, for example, the first terminal is the OLT 121, the second terminal is the ONT 131, and the like.

Exemplarily, the first terminal may support multiple services such as Internet access services and CDN services. In order to facilitate understanding of the embodiments of the present application, the following description is made by taking the first terminal supporting the Internet access service and the CDN service as an example. For example, when the first terminal is an ONT, the Internet service of the first terminal and the CDN service of the first terminal may be carried in the same wide area network (WAN), or the Internet service of the first terminal and the CDN of the first terminal may be carried in the same wide area network (WAN). Services can also be carried in different WANs. For another example, when the first terminal is an OLT, the Internet access service of the first terminal and the CDN service of the first terminal share the same uplink port or the same uplink port group.

Wherein, the Internet service of the first terminal and the CDN service of the first terminal are carried in the same WAN, which can be understood as the Internet service of the first terminal and the CDN service of the first terminal share the uplink bandwidth resources available to the first terminal (may be It is referred to as the uplink bandwidth resource or uplink bandwidth resource of the first terminal for short). The Internet service of the first terminal and the CDN service of the first terminal are carried in different WANs. It can be understood that the Internet service of the first terminal and the CDN service of the first terminal are respectively configured with independent uplink bandwidth resources. The amount of bandwidth resources occupied by the CDN service of the terminal has no effect on the bandwidth resources available for the Internet service of the first terminal. For example, the operator can configure uplink bandwidth resources for the Internet service and the CDN service respectively. The Internet service of the first terminal and the CDN service of the first terminal share the same uplink port, which can be understood as the Internet service of the first terminal and the CDN service of the first terminal sending uplink data to the server through the same uplink port. The Internet service of the first terminal and the CDN service of the first terminal share the same uplink port group, which can be understood as the Internet service of the first terminal and the CDN service of the first terminal are sent to the server through two uplink ports in the same uplink port group. Send upstream data. For example, uplink port group 1 includes uplink port 1, uplink port 2, and uplink port 3. The Internet service of the first terminal sends uplink data to the server through uplink port 1, and the CDN service of the first terminal sends uplink data to the server through uplink port 3. , the Internet access service of the first terminal and the CDN service of the first terminal share the same uplink port group.

Exemplarily, the first terminal may periodically or aperiodically determine its own uplink bandwidth resources and bandwidth resources occupied by Internet access services. For example, the first terminal may determine its own uplink bandwidth resources and bandwidth resources occupied by Internet access services every 10 seconds or every 5 seconds. In this way, the first terminal can send the actual usage of its own bandwidth resources to the server, so that the server determines whether to use the first terminal as a source node for providing the first data according to the actual usage of bandwidth resources of the first terminal.

As an example, the first terminal is an ONT, and the Internet service of the first terminal and the CDN service are carried in the same WAN, the first terminal can perform a bandwidth test to obtain the uplink bandwidth resources of the first terminal, and use a statistical counter to determine the first terminal's uplink bandwidth resources. The bandwidth resources occupied by the Internet access service of the terminal are counted to obtain the bandwidth resources occupied by the Internet access service of the first terminal. For example, the first terminal may test the communication speed of the first terminal by using a speed testing website such as a speed test (speed test) during idle time, so as to obtain the uplink bandwidth resources of the first terminal.

As another example, the first terminal is an OLT, and the Internet service of the first terminal and the CDN service share the same uplink port, the first terminal can obtain the uplink bandwidth resources of the first terminal by reading the bandwidth resources of the uplink port, and The bandwidth resources occupied by the Internet access service of the first terminal are counted by the statistical counter, so as to obtain the bandwidth resources occupied by the Internet access service of the first terminal.

In another possible implementation manner, the first terminal is an ONT, and the Internet access service of the first terminal and the CDN service are carried in different WANs. In step S301, the first terminal may directly determine the bandwidth resources of the CDN service of the first terminal. Since the Internet service of the first terminal and the CDN service are carried in different WANs, they are configured with independent bandwidth resources, which means that the amount of bandwidth resources occupied by the CDN service of the first terminal has no effect on the Internet service of the first terminal. , therefore, the first terminal may only determine the bandwidth resources of the CDN service of the first terminal. For example, the first terminal may test the communication speed of the first terminal through a speed testing website such as a speed test during idle time to obtain the bandwidth resources of the CDN service of the first terminal.

It can be understood that, the embodiment of the present application does not limit the sequence in which the first terminal determines the uplink bandwidth resources and determines the bandwidth resources occupied by the Internet access service. For example, the first terminal may simultaneously determine the uplink bandwidth resource and the bandwidth resource occupied by the Internet access service. For example, the first terminal may first determine the uplink bandwidth resource and then determine the bandwidth resource occupied by the Internet access service; for another example, the first terminal may first determine the bandwidth resource occupied by the Internet access service and then determine the uplink bandwidth resource.

S302: The first terminal sends a first message to the server. Accordingly, the server receives the first message.

The first message may include information about bandwidth resources of the CDN service.

Exemplarily, the information about the bandwidth resources of the CDN service may include the uplink bandwidth resources of the first terminal and the bandwidth resources occupied by the Internet service of the first terminal; or, the information about the bandwidth resources of the CDN service may only include the CDN service. bandwidth resources. The bandwidth resource of the CDN service can be used by the server to determine whether to request the first data from the first terminal. The bandwidth resource of the CDN service may be the difference between the uplink bandwidth resource of the first terminal and the bandwidth resource occupied by the Internet service of the first terminal. For example, after determining the uplink bandwidth resources and the bandwidth resources occupied by the Internet service, the first terminal may perform a difference calculation on the uplink bandwidth resources and the bandwidth resources occupied by the Internet service to obtain the bandwidth resources of the CDN service. For another example, after determining the uplink bandwidth resources and the bandwidth resources occupied by the Internet service, the first terminal can use the uplink bandwidth resources to subtract the bandwidth resources occupied by the Internet service, and then subtract the set threshold to obtain the bandwidth resources of the CDN service, so as to obtain the bandwidth resources of the CDN service. It is ensured that the first terminal can perform the Internet access service and the CDN service in parallel. The set threshold may be specified by a protocol or configured by a server, which is not limited in this embodiment of the present application.

Exemplarily, the first terminal may periodically or aperiodically send the first message to the server. For example, the first terminal sends the first message to the server every 5 seconds or every 10 seconds. In this way, the server can acquire the actual usage of the bandwidth resources of the first terminal, and determine whether to request the first data from the first terminal according to the actual usage of the bandwidth resources of the first terminal, thereby improving the accuracy of resource scheduling.

In another possible implementation manner, when the first terminal is an ONT, and the Internet service of the first terminal and the CDN service are carried in different WANs, in step S302, the first terminal may send the first message to the server, The first message may only include the bandwidth resources of the CDN service.

S303: The second terminal sends a first request message to the server. Correspondingly, the server receives the first request message.

Wherein, the first request message is used to obtain the first data. The second terminal may be an ONT or an OLT, and the specific form of the second terminal is not limited in this embodiment of the present application. For example, when the second terminal is an ONT, the first terminal may send the first request message to the server through the OLT connected thereto.

S304: The server determines whether to request the first terminal for the first data according to the information about the bandwidth resources of the CDN service.

Wherein, if the server determines to request the first data from the first terminal according to the information about the bandwidth resources of the CDN service, the content shown in steps S305 to S307 is executed; otherwise, the process ends.

Exemplarily, the server may determine that the first terminal is the source node that provides the first data according to an algorithm such as load balancing. For example, the server determines that the first terminal is the node that is closest to the second terminal and stores the first data. Further, the server may determine whether to request the first data from the first terminal according to the information about the bandwidth resources of the CDN service, that is, determine whether to use the first terminal as a source node for providing the first data. For example, the server may determine at least one node that stores the first data according to information such as the identifier of the first data, and the at least one node includes the first terminal; the server may use an algorithm such as load balancing to determine the highest priority from the at least one node The node, that is, the first terminal; furthermore, the server may determine whether to request the first data from the first terminal according to the information about the bandwidth resources of the CDN service. The highest priority may refer to the closest distance to the second terminal, etc., which is not limited in this embodiment of the present application.

Exemplarily, the server may determine the bandwidth resources of the CDN service according to the information about the bandwidth resources of the CDN service. For example, the information about the bandwidth resources of the CDN service includes the uplink bandwidth resources of the first terminal and the bandwidth resources of the Internet service of the first terminal. For example, the information about the bandwidth resources of the CDN service includes the uplink bandwidth resources and the bandwidth resources occupied by the Internet service. The bandwidth resource of the CDN service can be obtained by subtracting the bandwidth resource occupied by the Internet service from the uplink bandwidth resource, and then subtracting the set threshold.

Exemplarily, the server may determine whether to request the first data from the first terminal according to the information about the bandwidth resources of the CDN service. For example, the server may determine whether to request the first data from the first terminal according to the bandwidth resources of the CDN service. For example, if the bandwidth resources required to transmit the first data are less than or equal to the bandwidth resources of the CDN service, it means that the bandwidth resources available for the CDN service of the first terminal are sufficient to support the transmission of the first data, that is, the first terminal performs the CDN service. When the service does not affect the Internet service of the first terminal or the configured bandwidth resources of the CDN service can support the transmission of the first data, the server may determine to request the first data from the first terminal; or, if the transmission of the first data requires The bandwidth resources of the first terminal are larger than the bandwidth resources of the CDN service, which means that the bandwidth resources available for the CDN service of the first terminal are not enough to support the transmission of the first data, that is, when the first terminal performs the CDN service, the first terminal will not be able to access the Internet. If the service affects the service or the configured bandwidth resources of the CDN service cannot support the transmission of the first data, resulting in network congestion, the server may determine not to request the first data from the first terminal.

As an example, after the server determines not to request the first data from the first terminal, the server may determine other nodes whose priorities (such as distance priority, load priority, etc.) are lower than those of the first terminal and store the first data as The source node that provides the first data, then obtains the first data from the other node, and sends the first data to the second terminal; or, the server can also obtain the first data through the network and send the first data to the second terminal Two terminals.

S305: The server sends a second request message to the first terminal. Correspondingly, the first terminal receives the second request message.

Wherein, the second request message is used to obtain the first data. For example, when the first terminal is an ONT, the server may send the second request message to the first terminal through the OLT connected to the first terminal.

S306: The first terminal sends a second response message to the server. Correspondingly, the server receives the second response message.

Wherein, the second response message includes the first data. For example, when the first terminal is an ONT, the first terminal may send the second response message to the server through the OLT connected thereto.

S307: The server sends a first response message to the second terminal. Correspondingly, the second terminal receives the first response message.

The first response message includes first data. For example, when the second terminal is an ONT, the server may send the first response message to the second terminal through the OLT connected to the second terminal.
