Description

Scheduling method, device and system

Technical Field

The present application relates to the field of communications technologies, and in particular, to a scheduling method, apparatus, and system.

Background

The content delivery network (content delivery network, CDN) system may redirect the user's request to the service node closest to the user so that the user may obtain the desired content nearby to address the network congestion condition and increase the response speed of the user to access the website.

At least two nodes and servers may be included in the CDN system. Wherein each of the at least two nodes may inform the server of its own storage capacity when registering with the server. The server may schedule resources based on the 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; the node 2 sends a request message for acquiring the data 1 to a server; the server determines that the node closest to the node 2 is the node 1, the data 1 is stored in the node 1, and the server determines that the node 1 is a source node for providing the data 1; and the server acquires the data 1 by interacting with the node 1 and transmits the data 1 to the node 2.

However, the source node supports not only the CDN service but also the internet surfing service, and the CDN service and the internet surfing service of the source node share uplink bandwidth resources of the source node, so that the more bandwidth resources occupied by the CDN service, the less bandwidth resources available for the internet surfing service are, which causes network congestion and affects the internet surfing service of the source node.

Disclosure of Invention

The application provides a scheduling method, a scheduling device and a scheduling system, which are used for avoiding network congestion caused by CDN service.

In a first aspect, an embodiment of the present application provides a scheduling method, which may be performed by a first terminal or performed by a component (such as a processor, a chip, etc.) of the first terminal. In the method, a first terminal determines uplink bandwidth resources and bandwidth resources occupied by internet surfing services, and the first terminal stores first data which is requested to be acquired by a second terminal; and the first terminal sends a first message to the server, wherein the first message comprises information about bandwidth resources of CDN service, the bandwidth resources of the CDN service are differences between uplink bandwidth resources and bandwidth resources occupied by internet service, and the bandwidth resources of the CDN service are used for the server to determine whether to request the first data from the first terminal.

In the above embodiment, the first terminal sends, to the server, information about bandwidth resources of the CDN service by determining bandwidth resources occupied by the uplink bandwidth resources and bandwidth resources occupied by the internet service, where the bandwidth resources of the CDN service are a difference between the bandwidth resources occupied by the uplink bandwidth resources and the bandwidth resources occupied by the internet service, so that the server may determine whether to request the first data to the first terminal according to the bandwidth resources of the CDN service. For example, when the bandwidth resource of the CDN service shares the uplink bandwidth resource of the first terminal with the internet service, the server determines whether to use the first terminal as a source node of the first data according to the bandwidth resource of the CDN service, so that network congestion caused by fewer bandwidth resources available to the internet service due to more bandwidth resources occupied by the CDN service can be avoided, and normal internet service of the first terminal can be ensured.

In one possible design, the information about bandwidth resources of the CDN traffic may include upstream bandwidth resources and bandwidth resources occupied by the internet traffic. Or the information on bandwidth resources of the CDN service may include only bandwidth resources of the CDN service.

Through the design, the first terminal can send the uplink bandwidth resource and the bandwidth resource occupied by the internet service to the server, or can perform difference operation on the uplink bandwidth resource and the bandwidth resource occupied by the internet service to obtain the bandwidth resource of the CDN service, and then only send the bandwidth resource of the CDN service to the server, so that the flexibility can be improved.

In one possible design, the first terminal may be an optical network terminal, and the CDN service and the internet service may be carried in the same wide area network WAN. Correspondingly, the first terminal determines the uplink bandwidth resource, and can perform bandwidth test for the first terminal to obtain the uplink bandwidth resource.

In another possible design, the first terminal may also be an optical line terminal, and the CDN service and the internet surfing service may share the same uplink port. Correspondingly, the first terminal determines the uplink bandwidth resource, and the uplink bandwidth resource can be obtained by reading the bandwidth resource of the uplink port for the first terminal.

In a second aspect, embodiments of the present application provide a scheduling method that may be performed by a server or by a component (e.g., a processor, a chip, etc.) of the server. In the method, a server may receive a first message from a first terminal, where the first terminal stores first data, where the first message includes information about bandwidth resources of a CDN service, where the bandwidth resources of the CDN service may be a difference between uplink bandwidth resources of the first terminal and bandwidth resources occupied by an internet service of the first terminal, and receive a first request message from a second terminal, where the first request message is used to request to obtain the first data; the server may determine whether to request the first data from the first terminal according to the information on bandwidth resources of the CDN service.

In one possible design, the information about bandwidth resources of the CDN service may include uplink bandwidth resources and bandwidth resources occupied by the internet service; or the information on bandwidth resources of the CDN service may include only bandwidth resources of the CDN service.

In one possible design, the first terminal may be an optical network terminal, and the CDN service and the internet service may be carried in the same wide area network WAN. Correspondingly, the uplink bandwidth resource can be obtained by performing bandwidth test on the first terminal.

In another possible design, the first terminal may also be an optical line terminal, and the CDN service and the internet surfing service may share the same uplink port. Correspondingly, the uplink bandwidth resource can be obtained by the first terminal through reading the bandwidth resource of the uplink port.

In one possible design, the method may further include: and determining the bandwidth resources of the CDN service according to the information about the bandwidth resources of the CDN service. Correspondingly, the server determines whether to request the first data from the first terminal according to the information about the bandwidth resource of the CDN service, which may be: under the condition that the bandwidth resource required for transmitting the first data is smaller than or equal to the bandwidth resource of CDN service, the server determines to request the first data to the first terminal; or in the case that the bandwidth resource required for transmitting the first data is greater than the bandwidth resource of the CDN service, the server determines not to request the first data from the first terminal.

Through the design, the server can determine whether to take the first terminal as a source node for providing the first data according to the bandwidth resources available to CDN service of the first terminal. For example, the bandwidth resource required for transmitting the first data is less than or equal to the bandwidth resource of the CDN service, which indicates that the bandwidth resource available for the CDN service of the first terminal is sufficient to support the transmission of the first data, that is, the normal internet service of the first terminal is not affected, so the server may use the first terminal as a source node for providing the first data. For another example, the bandwidth resource required for transmitting the first data is greater than the bandwidth resource of the CDN service, which indicates that the bandwidth resource available for the CDN service of the first terminal is insufficient to support the transmission of the first data, if the first terminal is adhered to transmit the first data, the normal internet surfing service of the first terminal is affected, and network congestion is caused, so that the server may not use the first terminal as a source node for providing the first data, but may further select other terminals to provide the first data, so as to ensure the normal internet surfing service of the first terminal.

In one possible design, after the server requests the first data from the first terminal, the method may further include: the server receives first data from a first terminal; and the server transmits a first response message to the second terminal, the first response message including the first data.

In a third aspect, embodiments of the present application provide a scheduling method, which may be performed by a first terminal or by a component (such as a processor, or a chip, etc.) of the first terminal. In the method, a first terminal can determine bandwidth resources of CDN service, the first terminal stores first data acquired by a second terminal, wherein CDN service of the first terminal and Internet surfing service of the first terminal are carried in different wide area networks WAN; and the first terminal sends a first message to the server, wherein the first message comprises bandwidth resources of the CDN service, and the bandwidth resources of the CDN service can be used for the server to determine whether to request the first data from the first terminal.

In the above embodiment, the CDN service of the first terminal and the internet surfing service of the first terminal are carried in different WANs, which means that the CDN service of the first terminal is configured with independent bandwidth resources, that is, how much bandwidth resources occupied by the CDN service has no influence on the bandwidth resources that can be used by the internet surfing service of the first terminal. In this case, the first terminal may send the bandwidth resources of the CDN service that may be used to the server, so the server may determine, according to the bandwidth resources actually available to the CDN service of the first terminal, whether to use the first terminal as a source node for providing the first data, so that network congestion caused by that the bandwidth resources available to the CDN service are less and the bandwidth resources required for transmitting the first data are more may be avoided.

In one possible design, the first terminal determines bandwidth resources of the CDN service, and may perform a bandwidth test for the first terminal to obtain the bandwidth resources of the CDN service.

The method and the device are based on the same technical conception, and because the principles of solving the problems by the method and the device are similar, the embodiments of the device and the method can be mutually referred to, and the repetition is omitted.

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

The CDN system is a strategically deployed system, and can solve the problem of slow response speed of user access websites caused by small network bandwidth, large user access amount and uneven network point distribution. The CDN system aims to add a new network architecture into the existing Internet (internet) to release the content of the website to the network 'edge' closest to the user, so that the user can obtain the required content nearby, and the response speed of the user for accessing the website is improved.

Fig. 1 shows a schematic diagram of a CDN system to which embodiments of the present application may be applied. As shown in fig. 1, a server 110, and at least two nodes may be included in the CDN system. At least two nodes in fig. 1 are exemplified by an Optical Line Terminal (OLT) 121, an OLT 122, an optical network terminal (optical network terminal, ONT) 131, an ONT 132, an ONT 133, and an ONT 134. Wherein the ONT may communicate with the server 110 through the OLT. The OLT may act as an intermediary between the server 110 and the ONTs. For example, the OLT may forward data received from the server 110 to the ONTs as downstream data, and forward data received from the ONTs to the server 110 as upstream data.

By way of example, the server 110 may be a cloud server, a global load balancing (global server load balance, GSLB) server, a global scheduling server, or the like, and the specific implementation form of the server 110 is not limited in the embodiments of the present application. The server 110 may be configured to implement resource allocation between different nodes, so as to ensure that the user closest to the server is served by the best node, thereby ensuring access quality. For example, the ONT (or OLT) informs the server 110 of its own storage capability, and the server 110 may manage the storage capability of the ONT (or OLT). The ONT may support internet surfing services, CDN services, etc. The OLT may also support a network service, a CDN service, or the like. For example, the server 110 may pre-store the data 1 in the ONT 131 according to the storage capability of the ONT 131, and when other nodes request the server 110 to acquire the data 1, the server may send a request message to the ONT 131 requesting to acquire the data 1, and the ONT 131 may send the data 1 to the other nodes after receiving the request message.

It should be understood that fig. 1 is not limited to a CDN system to which the embodiments of the present application are applicable as an example. For example, the CDN system may also include more OLTs or ONTs. As another example, the CDN system may be applied not only to the optical communication technology field shown in fig. 1, but also to the wireless communication technology field and the like. In order to facilitate understanding of the embodiments of the present application, the CDN system shown in fig. 1 is described below as an example.

The following uses ONT 131 and ONT 133 as an example, and the transmission flow of the present CDN service is briefly described with reference to fig. 2.

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

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

S204 to S205: the ONT 133 sends a request message to acquire data 1 to the server 110 through the OLT 122.

S206: the server 110 receives a request message to acquire data 1 from the ONT 133 through the OLT 122, and determines that the ONT 131 is a source node providing data 1.

Illustratively, the server 110 may determine that the ONT 131 is the closest node to the ONT 133 and stores data 1 according to a load balancing algorithm or the like. The server 110 may then determine that the ONT 131 is the source node that provides data 1.

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

S207 to S208: the server 110 sends a request message to acquire data 1 to the ONT 131 through the OLT 121.

S209 to S212: the ONT 131 receives a request message for acquiring data 1 from the server 110 through the OLT 121, and transmits the data 1 to the ONT 133 through the OLT 121, the server 110, and the OLT 122. So far, the transmission flow of the CDN service is ended.

In the flow shown in fig. 2, the server 110 may select the ONT 131 closest to the ONT 133 as a source node, so that the ONT 133 may obtain required data nearby, which may improve the response speed of the user to access the website. However, the source node may support not only the CDN service, but also other services such as the internet service, where the CDN service shares uplink bandwidth resources with other services such as the internet service. For example, the more bandwidth resources occupied by the CDN service, the less bandwidth resources that can be used by the internet service, so that normal internet service of the source node may be affected, resulting in network congestion. As another example, the bandwidth resources available to the CDN traffic of the source node are inherently strained, and the bandwidth resources actually required by the CDN traffic are more, which also causes network congestion.

In view of this, the embodiment of the application provides a scheduling method. In the method, the first terminal may send information about bandwidth resources of the CDN service to the server, where the information about bandwidth resources of the CDN service may include bandwidth resources occupied by uplink bandwidth resources and internet surfing services, or may also include bandwidth resources of the CDN service. Therefore, the server can determine the bandwidth resources actually usable by the CDN service of the first terminal and determine whether to take the first terminal as a source node for providing data according to the bandwidth resources actually usable by the CDN service of the first terminal, so that the problem that network congestion occurs in the first terminal Internet surfing service due to the fact that the more bandwidth resources occupied by the CDN service are, the less bandwidth resources are usable by the Internet surfing service can be avoided, and normal Internet surfing service of the first terminal is further ensured.

It should be noted that, in the following embodiments, the steps performed by the terminal (e.g., the first terminal or the second terminal) may also be performed specifically by a module or a component inside the terminal (e.g., the first terminal or the second terminal), for example, may be performed by a chip or a chip system in the terminal (e.g., the first terminal or the second terminal); the steps performed by the server may also be performed in particular by a module or component within the server, such as by a chip or chip system in the server; the embodiment of the present application is not limited thereto.

Fig. 3 shows a flow chart of a scheduling method according to an embodiment of the present application. The method can be applied to the CDN system shown in FIG. 1. The first terminal may be an ONT or an OLT in fig. 1, the second terminal may be an ONT or an OLT in fig. 1 except for the first terminal, and the server may be the server 110 in fig. 1. As shown in fig. 3, the flow of the method may be as follows.

S301: the first terminal determines uplink bandwidth resources and bandwidth resources occupied by the Internet surfing service.

The first terminal stores first data requested to be acquired by the second terminal. The first data may be video data, audio data, or pictures, and the embodiment of the present application does not limit the specific form of the first data. For example, when the first terminal registers with the server, the first terminal may register its own internet protocol (internet protocol, IP) address, storage capability, and other information with the server, so that the server manages the storage capability of the first terminal. Further, the first terminal may acquire the first data by sending a request message for acquiring the first data to the server, and store the first data; or the first terminal can receive and store the first data actively pushed from the server. For example, the server may push video data of the hot spot program into the first terminal according to the capabilities 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 an ONT 131, and the second terminal is an ONT 132; or the first terminal and the second terminal may also be two ONTs under different OLTs, for example, the first terminal is an ONT 131, and the second terminal is an ONT 134; or the first terminal and the second terminal may both be OLT, for example, the first terminal is OLT 121, and the second terminal is OLT 122; or the first terminal may be an ONT, the second terminal may be an OLT, for example, the first terminal is an ONT 131, and the second terminal is an OLT 121; or the first terminal may be an OLT, the second terminal may be an ONT, e.g., the first terminal is OLT 121, the second terminal is ONT 131, etc.

For example, the first terminal may support multiple services such as a network service, a CDN service, and the like. In order to facilitate understanding of the embodiments of the present application, the following description will take, as an example, a first terminal supporting a network service and a CDN service. 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 (wide area network, WAN), or the internet service of the first terminal and the CDN service of the first terminal may also be carried in different WANs. For another example, when the first terminal is the OLT, the internet service of the first terminal and the CDN service of the first terminal share the same uplink port or the same uplink port group.

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 that the internet service of the first terminal and the CDN service of the first terminal share an uplink bandwidth resource (which may be simply referred to as an uplink bandwidth resource or an uplink bandwidth resource of the first terminal) that may be used by the first terminal. The internet service of the first terminal and the CDN service of the first terminal are carried in different WANs, which 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, that is, how much of the bandwidth resources occupied by the CDN service of the first terminal has no influence on the bandwidth resources available for the internet service of the first terminal, for example, an operator can respectively configure uplink bandwidth resources for the internet service and the CDN service. 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 that the internet service of the first terminal and the CDN service of the first terminal send 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 that the internet service of the first terminal and the CDN service of the first terminal send uplink data to the server through two uplink ports in the same uplink port group. For example, the uplink port group 1 includes an uplink port 1, an uplink port 2, and an uplink port 3, where the uplink data is sent to the server by the uplink port 1 by the internet service of the first terminal, and the uplink data is sent to the server by the CDN service of the first terminal by the uplink port 3, so that the internet service of the first terminal and the CDN service of the first terminal share the same uplink port group.

The first terminal may periodically or aperiodically determine its own uplink bandwidth resource and bandwidth resource occupied by the internet service. For example, the first terminal may determine its own uplink bandwidth resource and bandwidth resource occupied by the internet service every 10 seconds or every 5 seconds, etc. In this way, the first terminal may send its own actual use condition of the bandwidth resource 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 use condition of the bandwidth resource 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 may perform a bandwidth test to obtain an uplink bandwidth resource of the first terminal, and count, by using a statistics counter, bandwidth resources occupied by the internet service of the first terminal to obtain bandwidth resources occupied by the internet service of the first terminal. For example, the first terminal may test the communication speed of the first terminal through a speed measurement website such as a speed test (SPEED TEST) in idle time, so as to obtain 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, and the first terminal may obtain an uplink bandwidth resource of the first terminal by reading a bandwidth resource of the uplink port, and count, by using a statistics counter, bandwidth resources occupied by the internet service of the first terminal, to obtain bandwidth resources occupied by the internet service of the first terminal.

In another possible implementation, the first terminal is an ONT, and the internet service and the CDN service of the first terminal are carried in different WANs. In step S301, the first terminal may directly determine bandwidth resources of the CDN service of the first terminal. Because the internet service and the CDN service of the first terminal are loaded in different WANs, the internet service and the CDN service of the first terminal 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 influence on the internet service of the first terminal, so the first terminal can 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 in idle time through a speed measurement website such as a speed test, so as to obtain bandwidth resources of the CDN service of the first terminal.

It can be understood that, in the embodiment of the present application, the order of determining the uplink bandwidth resource and determining the bandwidth resource occupied by the internet service for the first terminal is not limited. For example, the first terminal may determine uplink bandwidth resources and bandwidth resources occupied by the internet service at the same time. For example, the first terminal may determine the uplink bandwidth resource first and then determine the bandwidth resource occupied by the internet service; for another example, the first terminal may determine the bandwidth resources occupied by the internet service first and then determine the uplink bandwidth resources.

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

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

For example, the information about bandwidth resources of the CDN service may include uplink bandwidth resources of the first terminal and bandwidth resources occupied by the internet service of the first terminal; or the information on bandwidth resources of the CDN service may include only bandwidth resources of the CDN service. The bandwidth resources of the CDN service may 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 a difference between an uplink bandwidth resource of the first terminal and a bandwidth resource occupied by an internet service of the first terminal. For example, after determining the uplink bandwidth resource and the bandwidth resource occupied by the internet service, the first terminal may perform a difference operation on the uplink bandwidth resource and the bandwidth resource occupied by the internet service to obtain the bandwidth resource of the CDN service. For another example, after determining the uplink bandwidth resource and the bandwidth resource occupied by the internet service, the first terminal may subtract the bandwidth resource occupied by the internet service from the uplink bandwidth resource, and subtract the set threshold value to obtain the bandwidth resource of the CDN service, so as to ensure that the first terminal can perform the internet service and the CDN service in parallel. The set threshold may be defined by a protocol, configured by a server, or the like, and embodiments of the present application are not limited.

For example, the first terminal may periodically or aperiodically transmit the first message to the server. For example, the first terminal transmits the first message to the server every 5 seconds or every 10 seconds. In this way, the server can acquire the actual use condition of the bandwidth resource of the first terminal, and determine whether to request the first data from the first terminal according to the actual use condition of the bandwidth resource 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 and the CDN service of the first terminal are carried in different WANs, in step S302, the first terminal may send a first message to the server, where the first message may only include 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.

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

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

The server determines, according to the information about the bandwidth resource of the CDN service, to request the first data to the first terminal, and then executes the contents shown in steps S305 to S307; otherwise, the flow ends.

The server may determine, according to an algorithm such as load balancing, that the first terminal is a source node for providing the first data, e.g., the server determines that the first terminal is a node closest to the second terminal and that the first terminal stores the first data, and further the server may determine, according to information about bandwidth resources of the CDN service, whether to request the first data from the first terminal, i.e., 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 storing the first data according to information such as an identification of the first data, where the at least one node includes the first terminal; the server can adopt load balancing algorithm and the like to determine the node with the highest priority, namely the first terminal, from the at least one node; and the server may determine whether to request the first data from the first terminal according to the information about bandwidth resources of the CDN service. The highest priority may refer to the closest distance between the second terminal and the second terminal, which is not limited by the embodiment of the present application.

For example, the server may determine the bandwidth resource of the CDN service according to the information about the bandwidth resource of the CDN service, where the information about the bandwidth resource of the CDN service includes an uplink bandwidth resource of the first terminal and a bandwidth resource of an internet service of the first terminal. For example, the information about bandwidth resources of the CDN service includes uplink bandwidth resources and bandwidth resources occupied by the internet service, and the server may perform a difference operation on the uplink bandwidth resources and the bandwidth resources occupied by the internet service to obtain bandwidth resources of the CDN service; or the server can subtract the bandwidth resources occupied by the internet service from the uplink bandwidth resources and subtract the set threshold value to obtain 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 information about bandwidth resources of the CDN service. For example, the server may determine whether to request the first data from the first terminal according to bandwidth resources of the CDN service. For example, if the bandwidth resource required for transmitting the first data is less than or equal to the bandwidth resource of the CDN service, which means that the bandwidth resource available for the CDN service of the first terminal is sufficient to support transmission of the first data, that is, the bandwidth resource of the CDN service that does not affect or configure the internet service of the first terminal when the first terminal performs the CDN service can support transmission of the first data, the server may determine to request the first data to the first terminal; or if the bandwidth resource required for transmitting the first data is greater than the bandwidth resource of the CDN service, which means that the bandwidth resource available for the CDN service of the first terminal is insufficient to support the transmission of the first data, that is, the first terminal may affect the internet access service of the first terminal when performing the CDN service or the configured bandwidth resource of the CDN service cannot support the transmission of the first data, so as to cause network congestion, the server may determine not to request the first data to the first terminal.

As one example, after the server determines that the first data is not requested from the first terminal, the server may determine other nodes having a priority (e.g., a distance priority, a load priority, etc.) lower than the first terminal and storing the first data as source nodes for providing the first data, and then acquire the first data from the other nodes and transmit the first data to the second terminal; or the server may acquire the first data through the network and send the first data to the second terminal.

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 for acquiring the first data. For example, when the first terminal is an ONT, the server may send a second request message to the first terminal through an OLT connected with 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 a 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.

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