其中，该管道包括N个转发设备。待传输数据在该管道中传输时，满足业务需求信息中指示的需求。N为大于或等于1的整数。Wherein, the pipeline includes N forwarding devices. When the data to be transmitted is transmitted in the pipeline, the requirements indicated in the service requirement information are met. N is an integer greater than or equal to 1.
一种可能的实现方式，在网络初始建立时，控制器获取第一对应关系和第二对应关系。In a possible implementation manner, when the network is initially established, the controller acquires the first correspondence and the second correspondence.
其中，第一对应关系为第一网关设备的地址与网络中的第一转发设备的用户网络接口(user-to-network interface，UNI)的对应关系。第二对应关系为第二网关设备的地址与网络中的第二转发设备的UNI的对应关系。该第一转发设备与该第一网关设备连接，该第二转发设备与该第二网关设备连接。第一网关设备的地址可以为第一网关设备的IP地址。第二网关设备的地址可以为第二网关设备的IP地址。The first correspondence is the correspondence between the address of the first gateway device and the user-to-network interface (UNI) of the first forwarding device in the network.

The first forwarding device is connected to the first gateway device, and the second forwarding device is connected to the second gateway device. The address of the first gateway device may be the IP address of the first gateway device. The address of the second gateway device may be the IP address of the second gateway device.

UNI 2UNI 2 第二网关设备的地址The address of the second gateway device
一种可能的实现方式，控制器可以通过接口探测上述第一对应关系和第二对应关系。例如，控制器可以将包括第一网关设备的地址或第二网关设备的地址的地址解析协议(address resolution protocol，ARP)请求广播到网络中所有的设备上，并接收返回消息。后续，控制器可以根据返回消息确定第一对应关系和第二对应关系。In a possible implementation manner, the controller may detect the above-mentioned first correspondence and second correspondence through an interface.

Subsequently, the controller may determine the first correspondence and the second correspondence according to the returned message.
可以理解的，后续，若第一对应关系和第二对应关系未发生变化的情况下，控制器不需要再次获取第一对应关系和第二对应关系。It can be understood that, subsequently, if the first corresponding relationship and the second corresponding relationship do not change, the controller does not need to acquire the first corresponding relationship and the second corresponding relationship again.
一种可能的实现方式，控制器根据业务需求信息，在网络中为待传输数据建立管道，包括：控制器根据业务需求信息、第一对应关系和第二对应关系在网络中为待传输数据建立管道。A possible implementation manner, the controller establishes a pipeline for the data to be transmitted in the network according to the service requirement information, including: the controller establishes a pipeline for the data to be transmitted in the network according to the service requirement information, the first correspondence and the second correspondence. pipeline.

It should be understood that in practical applications, the resources used by the forwarding device also include other information, which is not limited.
其中，转发表包括入接口的标识，以及该入接口的标识对应的出接口的标识。示例性的，以图4所示的网络为例，若转发设备404通过接口1与网关设备402连接，转发设备404通过接口2与转发设备405连接，则转发设备404对应的转发表包括：接口1，以及与接口1对应的接口2。The forwarding table includes the identifier of the inbound interface and the identifier of the outbound interface corresponding to the identifier of the inbound interface. Exemplarily, taking the network shown in FIG. 4 as an example, if the forwarding device 404 is connected to the gateway device 402 through the interface 1, and the forwarding device 404 is connected to the forwarding device 405 through the interface 2, the forwarding table corresponding to the forwarding device 404 includes: 1, and interface 2 corresponding to interface 1.
示例性的，控制器根据待传输数据的源地址、待传输数据的目的地址、第一对应关系和第二对应关系确定与第一网关设备连接的第一转发设备和与第二网关设备连接的第二转发设备；控制器根据网络拓扑和业务需求信息确定第一转发设备和第二转发设备之间的转发设备，以及第一网关设备、第二网关设备和N个转发设备中每个转发设备使用的资源和转发表。其中，第一转发设备、第二转发设备以及第一转发设备和第二转发设备之间的转发设备包括在N个转发设备中。Exemplarily, the controller determines the first forwarding device connected to the first gateway device and the first forwarding device connected to the second gateway device according to the source address of the data to be transmitted, the destination address of the data to be transmitted, the first correspondence and the second correspondence. the second forwarding device; the controller determines the forwarding device between the first forwarding device and the second forwarding device, and each forwarding device among the first gateway device, the second gateway device and the N forwarding devices according to the network topology and service requirement information Resources and forwarding tables used. The first forwarding device, the second forwarding device, and the forwarding device between the first forwarding device and the second forwarding device are included in the N forwarding devices.
可以理解的，N值不同时，网络拓扑结构不同。It can be understood that when the value of N is different, the network topology is different.
示例性的，当N为1时，第一网关设备与第二网关设备通过一个转发设备连接。Exemplarily, when N is 1, the first gateway device and the second gateway device are connected through a forwarding device.
示例性的，当N为2时，第一网关设备与第一转发设备、第二转发设备、第二网关设备依次相连。以图4为例，第一网关设备为网关设备402，第一转发设备为转发设备404，第二转发设备为转发设备405，第二网关设备为网关设备403。Exemplarily, when N is 2, the first gateway device is connected to the first forwarding device, the second forwarding device, and the second gateway device in sequence. Taking FIG. 4 as an example, the first gateway device is the gateway device 402 , the first forwarding device is the forwarding device 404 , the second forwarding device is the forwarding device 405 , and the second gateway device is the gateway device 403 .
示例性的，当N为3时，网络的拓扑结构可以如图5所示。图5中，第一网关设备为网关设备502，第一转发设备为转发设备504，第二转发设备为转发设备505，第一转发设备和第二转发设备之间的转发设备为转发设备506，第二网关设备为网关设备503。Exemplarily, when N is 3, the topology of the network may be as shown in FIG. 5 .

可以理解的，当N大于3时，第一转发设备和第二转发设备之间的转发设备的个数大于1，也就是说，在这种情况下，第一转发设备和第二转发设备通过多个转发设备连接。It can be understood that when N is greater than 3, the number of forwarding devices between the first forwarding device and the second forwarding device is greater than 1, that is, in this case, the first forwarding device and the second forwarding device pass through. Multiple forwarding device connections.
可以理解的，控制器根据业务需求信息、第一对应关系和第二对应关系确定转发资源以及N个转发设备中，每个转发设备的转发表之后，可以分别向N个转发设备发送N个转发设备中每个转发设备对应的转发资源和转发表。控制器还向第一网关设备发送第一网关设备对应的转发资源和转发表，向第二网关设备发送第二网关设备对应的转发资源和转发表。It can be understood that the controller determines the forwarding resources and the N forwarding devices according to the service requirement information, the first corresponding relationship and the second corresponding relationship.

可以理解的，本申请实施例中，N个转发设备中每个转发设备对应的转发资源、第一网关设备对应的转发资源和第二网关设备对应的转发资源都是待传输数据专用的资源。也就是说，上述每个转发设备对应的转发资源、第一网关设备对应的转发资源和第二网关设备对应的转发资源是用于传输上述待传输数据的，不能用于其他业务。因此，待传输数据在管道中传输时，可以满足业务需求信息中指示的需求。It can be understood that, in this embodiment of the present application, the forwarding resources corresponding to each of the N forwarding devices, the forwarding resources corresponding to the first gateway device, and the forwarding resources corresponding to the second gateway device are all resources dedicated to data to be transmitted. That is to say, the forwarding resources corresponding to each of the forwarding devices, the forwarding resources corresponding to the first gateway device, and the forwarding resources corresponding to the second gateway device are used for transmitting the data to be transmitted, and cannot be used for other services. Therefore, when the data to be transmitted is transmitted in the pipeline, the demand indicated in the business demand information can be satisfied.
一种可能的实现方式，步骤304之后，控制器向第一网关设备发送业务需求信息的响应信息。该响应信息用于指示管道是否建立成功。第一网关设备接收到该响应信息后，向终端发送该响应信息。In a possible implementation manner, after step 304, the controller sends the response information of the service requirement information to the first gateway device. The response information is used to indicate whether the pipeline is established successfully. After receiving the response information, the first gateway device sends the response information to the terminal.
可以理解的，在步骤304之后，终端通过该管道与业务服务器通信。It can be understood that after step 304, the terminal communicates with the service server through the pipeline.
基于图3所示的方法，终端可以通过第一网关设备向控制器发送用于指示待传输数据对网络的需求的业务需求信息。控制器接收到该业务需求信息后，可以根据该业务需求信息，在网络中为待传输数据建立满足待传输数据对网络的需求的管道。其中，管道中的转发设备、第一网关设备或第二网关设备使用的转发资源都是控制器根据业务需求信息为待传输数据配置的，因此，待传输数据在该管道中传输时，可以满足待传输数据对网络的需求，另外，还可以提高网络资源的利用率。Based on the method shown in FIG. 3 , the terminal may send, to the controller through the first gateway device, service requirement information for indicating the requirement of the data to be transmitted on the network. After receiving the service requirement information, the controller can, according to the service requirement information, establish a pipeline for the data to be transmitted in the network that meets the requirement of the data to be transmitted on the network. The forwarding resources used by the forwarding device, the first gateway device or the second gateway device in the pipeline are all configured by the controller for the data to be transmitted according to the service requirement information. Therefore, when the data to be transmitted is transmitted in the pipeline, it can satisfy the The network demand of the data to be transmitted can also be improved, and the utilization rate of network resources can also be improved.
可选的，在图3所示方法的第一种可能的实现方式中，终端与业务服务器通信的过程中，上述业务需求信息会发生变化。例如，终端用户切换视频的清晰度时，业务需求信息会发生变化。此时，终端需要通过第一网关设备向控制器发送更新需求信息，以便控制器根据更新需求信息，更新原先的管道或者重新建立管道。具体的，如图6所示，图3所示的方法还包括步骤601-步骤603。Optionally, in the first possible implementation manner of the method shown in FIG. 3 , during the communication between the terminal and the service server, the above-mentioned service requirement information may change. For example, when the end user switches the resolution of the video, the service requirement information will change. At this time, the terminal needs to send the update requirement information to the controller through the first gateway device, so that the controller can update the original pipeline or re-establish the pipeline according to the update demand information. Specifically, as shown in FIG. 6 , the method shown in FIG. 3 further includes steps 601 to 603 .
步骤601：终端向第一网关设备发送更新需求信息。Step 601: The terminal sends update requirement information to the first gateway device.

The information includes bandwidth information 1, delay information 1, packet loss rate 1, and delay jitter information 2.
可以理解的，控制器确定了更新后的业务需求信息后，可以重新在网络中建立管道，也可以不重新建立管道。若控制器确定重新建立管道，控制器会将上述步骤304中建立的管道拆除，再重新建立管道。控制器重新在网络中建立管道的过程与步骤304中建立管道的过程类似，具体的，可以参考上述步骤304中建立管道的过程，不予赘述。若控制器确定不重新建立管道，可以更新上述管道。It can be understood that, after the controller determines the updated service requirement information, it can re-establish the pipeline in the network, or it can not re-establish the pipeline. If the controller determines to re-establish the pipeline, the controller will remove the pipeline established in the above step 304, and then re-establish the pipeline. The process of the controller re-establishing the pipeline in the network is similar to the process of establishing the pipeline in step 304. For details, reference may be made to the process of establishing the pipeline in the above-mentioned step 304, which will not be repeated. If the controller determines not to re-establish the pipeline, the pipeline can be updated.

The response information is used to indicate whether the pipeline is updated successfully, or whether the pipeline is re-established successfully. After receiving the response information, the first gateway device sends the response information to the terminal.
可以理解的，在步骤603之后，终端通过该更新后的管道，或重新建立的管道与业务服务器通信。It can be understood that after step 603, the terminal communicates with the service server through the updated pipeline or the re-established pipeline.

After receiving the update requirement information, the controller can update the originally established pipeline or re-establish the pipeline according to the update requirement information. In this way, when the data to be transmitted is transmitted in the updated pipeline or the re-established pipeline, the new demand of the data to be transmitted on the network can be satisfied.
可选的，在图3所示方法的第二种可能的实现方式中，终端与业务服务器结束通信时，终端可以通过第一网关设备向控制器发送访问结束通知消息，以便控制器拆除管道。具体的，如图7所示，图3所示的方法还包括步骤701-步骤703。Optionally, in the second possible implementation manner of the method shown in FIG. 3 , when the terminal ends communication with the service server, the terminal may send an access end notification message to the controller through the first gateway device, so that the controller removes the pipeline.

In this way, the N forwarding devices or the forwarding resources corresponding to the N forwarding devices can be subsequently allocated to other services, which can improve the utilization rate of the forwarding devices and the utilization rate of the resources in the network.
上述图7所示的方法中，终端在通信结束时，通过第一网关设备通知控制器拆除管道。除此之外，在图3所示方法的第三种可能的实现方式中，第一网关设备也可以通知控制器拆除管道。在这种情况下，第一网关设备可以具备监控终端对网络的使用情况的功能。具体的，如图8所示，图3所示的方法还包括步骤801-步骤803。In the above method shown in FIG. 7 , when the communication ends, the terminal notifies the controller to remove the pipeline through the first gateway device. Besides, in a third possible implementation manner of the method shown in FIG. 3 , the first gateway device may also notify the controller to remove the pipeline. In this case, the first gateway device may have the function of monitoring the usage of the network by the terminal. Specifically, as shown in FIG. 8 , the method shown in FIG. 3 further includes steps 801 to 803 .
步骤801：第一网关设备确定停止使用控制器为待传输数据建立的管道。Step 801: The first gateway device determines to stop using the pipe established by the controller for the data to be transmitted.
第一网关设备可以在下述示例性的情况下，确定停止使用控制器为待传输数据建立的管道。The first gateway device may determine to stop using the pipe established by the controller for the data to be transmitted under the following exemplary circumstances.
示例性的，在预设时间内，第一网关设备未检测到终端通过管道与业务服务器通信，第一网关设备确定停止使用控制器为待传输数据建立的管道。Exemplarily, within a preset time, the first gateway device does not detect that the terminal communicates with the service server through the pipeline, and the first gateway device determines to stop using the pipeline established by the controller for the data to be transmitted.
示例性的，第一网关设备检测到终端会员身份到期时，确定停止使用控制器为待传输数据建立的管道。Exemplarily, when the first gateway device detects that the terminal membership expires, it determines to stop using the pipe established by the controller for the data to be transmitted.
示例性的，第一网关设备检测到终端的账户余额小于或等于门限值时，确定停止使用控制器为待传输数据建立的管道。Exemplarily, when the first gateway device detects that the account balance of the terminal is less than or equal to the threshold value, it determines to stop using the pipe established by the controller for the data to be transmitted.
步骤802：第一网关设备向控制器发送访问结束通知消息。Step 802: The first gateway device sends an access end notification message to the controller.
其中，访问结束通知消息用于指示拆除控制器为终端和业务服务器建立的管道。The access end notification message is used to instruct to remove the pipeline established by the controller for the terminal and the service server.
一种可能的实现方式，访问结束通知消息包括终端的地址和业务服务器的地址，以便通知控制器该访问结束通知消息是针对哪条管道，或针对哪个业务需求信息的。In a possible implementation manner, the access end notification message includes the address of the terminal and the address of the service server, so as to notify the controller which pipeline or service requirement information the access end notification message is for.
对应的，控制器接收来自第一网关设备的访问结束通知消息。Correspondingly, the controller receives an access end notification message from the first gateway device.
步骤803：控制器根据访问结束通知消息拆除上述管道。Step 803: The controller removes the above-mentioned pipe according to the access end notification message.

The indication information is used to instruct to delete the forwarding resource and forwarding table configured for the data to be transmitted on each device.
可以理解的，上述步骤801-步骤803也可以在步骤603之后执行。It can be understood that the above steps 801 to 803 can also be executed after step 603 .
基于图8所示的方法，第一网关设备确定停止使用控制器为待传输数据建立的管道后，可以向控制器发送访问结束通知消息，以便控制器根据该访问结束通知消息拆除管道。如此，上述N个转发设备或N个转发设备对应的转发资源后续可以被分配给其他业务，可以提高网络中转发设备的利用率，以及资源的利用率。Based on the method shown in FIG. 8 , after the first gateway device determines to stop using the pipe established by the controller for the data to be transmitted, it can send an access end notification message to the controller, so that the controller removes the pipe according to the access end notification message. In this way, the N forwarding devices or the forwarding resources corresponding to the N forwarding devices can be subsequently allocated to other services, which can improve the utilization rate of the forwarding devices and the utilization rate of the resources in the network.
可以理解的，在常规技术中，终端与业务服务器通过三次握手建立连接后，由于不知道网络的传输能力，终端和业务服务器通信时，会采用试探的方法传输数据。It can be understood that, in the conventional technology, after the terminal and the service server establish a connection through three-way handshake, since the terminal does not know the transmission capability of the network, when the terminal communicates with the service server, a tentative method is used to transmit data.
以业务服务器向终端发送数据为例，一开始业务服务器采用第一带宽向终端发送数据。在预设时间内，丢包率小于或等于阈值时，业务服务器采用第二带宽向终端发送数据，第二带宽大于第一带宽。若在预设时间内，丢包率小于或等于阈值，业务服务器采用第三带宽向 终端发送数据，第三带宽大于第二带宽；若在预设时间内，丢包率大于或等于阈值，业务服务器采用第四带宽向终端发送数据，第四带宽小于第二带宽。因此，在常规技术中，业务服务器向终端发送数据的过程中，吞吐量可以如图9A所示。在上述过程中，业务服务器要不断试探合适的带宽，会经常出现丢包的情况，而且，在数据开始传输的一段时间内，为了避免丢包，业务服务器使用的带宽较小，会产生时延。基于上述问题，终端可以与业务服务器协商网络参数，并通过协商后的网络参数通信。Taking the service server sending data to the terminal as an example, initially the service server uses the first bandwidth to send data to the terminal. Within the preset time, when the packet loss rate is less than or equal to the threshold, the service server uses the second bandwidth to send data to the terminal, and the second bandwidth is greater than the first bandwidth. If the packet loss rate is less than or equal to the threshold within the preset time, the service server uses the third bandwidth to send data to the terminal, and the third bandwidth is greater than the second bandwidth; if the packet loss rate is greater than or equal to the threshold within the preset time, the service The server uses a fourth bandwidth to send data to the terminal, and the fourth bandwidth is smaller than the second bandwidth. Therefore, in the conventional technology, in the process of the service server sending data to the terminal, the throughput can be as shown in FIG. 9A . In the above process, the service server has to constantly try to find the appropriate bandwidth, and packet loss will often occur. Moreover, within a period of time when the data starts to be transmitted, in order to avoid packet loss, the bandwidth used by the service server is small, which will cause delay. . Based on the above problem, the terminal can negotiate network parameters with the service server, and communicate through the negotiated network parameters.
可选的，在图3所示方法的第四种可能的实现方式中，终端可以通过管道通知业务服务器管道的网络参数，以便终端和业务服务器根据该网络参数通信。具体的，如图10所示，图3所示的方法还包括步骤1001-步骤1002。Optionally, in a fourth possible implementation manner of the method shown in FIG. 3 , the terminal may notify the service server of the network parameters of the pipe through the pipe, so that the terminal and the service server communicate according to the network parameters. Specifically, as shown in FIG. 10 , the method shown in FIG. 3 further includes steps 1001 to 1002 .
步骤1001：终端向业务服务器发送协商信息。Step 1001: The terminal sends negotiation information to the service server.
其中，协商信息用于通知业务服务器，管道的网络参数。示例性的，协商信息包括以下信息中的至少一种：带宽信息、时延信息或丢包率。其中，带宽信息用于指示该管道对应的带宽，时延信息用于指示该管道对应的时延，该丢包率为该管道对应的丢包率。The negotiation information is used to notify the service server of the network parameters of the pipeline. Exemplarily, the negotiation information includes at least one of the following information: bandwidth information, delay information or packet loss rate. The bandwidth information is used to indicate the bandwidth corresponding to the pipe, the delay information is used to indicate the delay corresponding to the pipe, and the packet loss rate is the packet loss rate corresponding to the pipe.
一种可能的实现方式，终端通过管道向业务服务器发送协商信息。In a possible implementation manner, the terminal sends negotiation information to the service server through a pipeline.
一种可能的实现方式，终端与业务服务器进行三次握手并建立连接之后，向业务服务器发送协商信息。In a possible implementation manner, after the terminal performs three-way handshake with the service server and establishes a connection, the terminal sends negotiation information to the service server.
对应的，业务服务器接收来自终端的协商信息。Correspondingly, the service server receives the negotiation information from the terminal.
步骤1002：终端根据网络参数与业务服务器通信。Step 1002: The terminal communicates with the service server according to the network parameters.
一种可能的实现方式，终端通过管道与业务服务器通信。In a possible implementation manner, the terminal communicates with the service server through a pipeline.
可以理解的，此时终端和业务服务器都知道了该管道的网络参数，因此，终端和业务服务器不需要采用试探的方法传输数据，而是采用上述管道的网络参数传输数据。在这种情况下，吞吐量可以如图9B所示。It is understandable that both the terminal and the service server know the network parameters of the pipeline at this time. Therefore, the terminal and the service server do not need to use a tentative method to transmit data, but use the network parameters of the pipeline to transmit data. In this case, the throughput can be as shown in Figure 9B.
基于图10所示的方法，终端可以通知业务服务器管道的网络参数，并和业务服务器根据该网络参数通信。如此，终端根据该网络参数和业务服务器通信时，可以获得较大，较稳定的吞吐量，并减少试探传输带来的丢包和时延。Based on the method shown in FIG. 10 , the terminal can notify the service server of the network parameters of the pipeline, and communicate with the service server according to the network parameters. In this way, when the terminal communicates with the service server according to the network parameters, a larger and more stable throughput can be obtained, and packet loss and delay caused by the tentative transmission can be reduced.

可以理解的，图1B所示的通信***中，终端和业务服务器通过两个不同域的网络通信的。在实际应用中，终端和业务服务器还可以通过三个或更多个不同域的网络通信。这种情况下建立管道的方法，与终端和业务服务器通过两个不同域的网络通信时，建立管道的方法类似，因此，可以参考下述图11-图15所示的方法。It can be understood that, in the communication system shown in FIG. 1B , the terminal and the service server communicate through two networks of different domains.

对应的，网关设备1072通过至少一个转发设备接收来自网关设备1071的业务需求信息。Correspondingly, the gateway device 1072 receives the service requirement information from the gateway device 1071 through at least one forwarding device.

基于图11所示的方法，终端105可以通过网关设备1071向控制器1073发送用于指示待传输数据对网络的需求的业务需求信息。控制器1073接收到该业务需求信息后，可以根据该业务需求信息，在网络107中为待传输数据建立满足待传输数据对网络的需求的管道1。终端105还可以通过网关设备1071、网关设备1072和网关设备1081向控制器1083发送用于指示待传输数据对网络的需求的业务需求信息。控制器1083接收到该业务需求信息后，可以根据该业务需求信息，在网络108中为待传输数据建立满足待传输数据对网络的需求的管道2。其中，管道1中的转发设备、网关设备1071或网关设备1072使用的转发资源都是控制器1073根据业务需求信息为待传输数据配置的。管道2中的转发设备、网关设备1081或网关设备1082使用的转发资源都是控制器1083根据业务需求信息为待传输数据配置的。因此，待传输数据在该管道1和管道2中传输时，可以满足待传输数据对网络的需求，另外，还可以提高网络资源的利用率。Based on the method shown in FIG. 11 , the terminal 105 may send the service requirement information to the controller 1073 through the gateway device 1071 for indicating the requirement of the data to be transmitted on the network. After receiving the service requirement information, the controller 1073 can establish a pipeline 1 for the data to be transmitted in the network 107 that meets the network requirement of the data to be transmitted according to the service requirement information. The terminal 105 may also send, to the controller 1083 through the gateway device 1071 , the gateway device 1072 and the gateway device 1081 , service requirement information for indicating the network requirements of the data to be transmitted. After receiving the service requirement information, the controller 1083 can establish a pipeline 2 for the data to be transmitted in the network 108 that meets the network requirement of the data to be transmitted according to the service requirement information. The forwarding resources used by the forwarding device, the gateway device 1071 or the gateway device 1072 in the pipeline 1 are all configured by the controller 1073 for the data to be transmitted according to the service requirement information.

可选的，在图11所示方法的第一种可能的实现方式中，终端105与业务服务器106通信的过程中，上述业务需求信息会发生变化。例如，终端105用户切换视频的清晰度时，业务需求信息会发生变化。此时，终端105需要通过网关设备1071向控制器1073发送更新需求信息，以便控制器1073根据更新需求信息，更新原先的管道1或者重新建立管道3。终端105还需要通过网关设备1071、网关设备1072和网关设备1081向控制器1083发送更新需求信息，以便控制器1083根据更新需求信息，更新原先的管道2或者重新建立管道4。具体的，如图12所示，图11所示的方法还包括步骤1201-步骤1207。Optionally, in the first possible implementation manner of the method shown in FIG. 11 , during the communication between the terminal 105 and the service server 106 , the above-mentioned service requirement information will change. For example, when the user of the terminal 105 switches the definition of the video, the service requirement information will change. At this time, the terminal 105 needs to send the update requirement information to the controller 1073 through the gateway device 1071, so that the controller 1073 updates the original pipe 1 or re-establishes the pipe 3 according to the update requirement information. The terminal 105 also needs to send the update requirement information to the controller 1083 through the gateway device 1071, the gateway device 1072 and the gateway device 1081, so that the controller 1083 can update the original pipeline 2 or re-establish the pipeline 4 according to the update demand information.
