As shown in FIG. 7 , the service transmission method provided by the embodiment of the present application is applied to a gateway device, including: S701-S703.

S701. The gateway device receives a first service message for requesting transmission of a target service.

Wherein, the target service is a fixed network service sent through a fixed network or a mobile network service sent through a mobile network.

Specifically, during the service transmission process, the gateway device can receive the fixed network service sent by the sender through the fixed network or the mobile network service sent through the mobile network through the ASIC, so that the gateway device can send messages to the fixed network service or the mobile network service Forward processing.

Specifically, after receiving the first service message, in order to transmit the second service message of the service message to the receiving end according to the routing strategy, the gateway device can determine the corresponding routing strategy.

Optionally, the routing policy may refer to the target network segment, mask, next-hop device, metric value, and so on.

Specifically, since the first service message is a service message communicated between the sending end and the gateway device, and the second service message is a service message communicated between the gateway device and the receiving end, it is used to transmit the data message of the first service message It is different from the data packet used to transmit the second service message. Therefore, according to the network type corresponding to the target service, the gateway device can call the target driver corresponding to the above network type to perform data packet decapsulation processing on the first service message, so that the gateway device can update the first service message to the second service message. 2.

Alternatively, the gateway device determines, according to the address field carried in the received first service message, that the network type corresponding to the address field is the network type of the target service.

Exemplarily, the packet header received by the default gateway device for transmitting the first service message of service A includes a point-to-point protocol over ethernet (PPPoE) address field. Since the PPPoE address field corresponds to a fixed network, the gateway device determines that service A is a fixed network service. After the gateway device determines that the routing policy of service A includes the receiving end, it invokes the ASIC-driver to process the data packets of the first service message, and then obtains the second service message. Then, the gateway device sends the second service message to the receiving end through the ASIC-driver.

In one embodiment, as shown in FIG. 8, before S801, further includes: S802.

S802. The gateway device invokes the target computing resource for the target driver, so that the target driver performs encapsulation and decapsulation of the data packet on the first service message.

Specifically, before invoking the target driver to perform encapsulation and decapsulation processing on the data message of the first service message, the gateway device may determine a hardware module or a software module corresponding to the service identifier according to the service identifier of the target service. Then, the gateway device invokes a corresponding hardware module or software module to provide the target driver with target computing resources, so that the target driver performs encapsulation and decapsulation of the data packet on the first service message.

Referring to FIG. 3 , the resource scheduling module of the gateway device can determine the hardware module or software module corresponding to the service identifier according to the service identifier of the target service. Then, the resource scheduling module sends a request message requesting invocation to the corresponding hardware module or software module. The corresponding hardware module or software module provides the target computing resource for the target driver in response to the request message.

Optionally, the computing resources are CPU resources, memory resources, hard disk resources, and network resources required by the gateway device during operation. In one embodiment, referring to FIG. 8, as shown in FIG. 9, before S703, the method further includes: S901.

S901. When the target service is a service type that cannot be processed by the target driver, the gateway device invokes another driver other than the target driver to perform encapsulation and decapsulation of data packets on the first service message to obtain a second service message.

Specifically, when receiving the first service message, the gateway device may determine according to the service identifier whether the target service is a service type that cannot be processed by the target driver. When the target service is a service type that cannot be processed by the target driver, the gateway device can call another driver other than the target driver to perform data packet processing on the first service message to obtain the second service message, so that the gateway device can Flexible handling of various types of business.

Optionally, referring to FIG. 3 , another driver may be the FPGA-driver in the kernel layer of the gateway device.

Exemplarily, the first service message (including the service identifier a) received by the gateway device and used to transmit the service A is preset. When the target service is determined to be a service type that cannot be processed by the target driver according to the service identifier a, after the gateway device determines that the routing policy of service A includes the receiving end, it can call the FPGA-driver to perform data packet decapsulation processing on the first service message , get the second service message. Then, the gateway device sends the second service message to the receiving end through the FPGA-driver.

When the target service is a fixed network service, the target container is the first container used to determine the routing policy corresponding to the fixed network service; when the target service is a mobile network service, the target container is the first container used to determine the routing policy corresponding to the mobile network service second container.

Specifically, when the gateway device receives the first service message, it may determine the network type corresponding to the target service. Then, the target driver of the gateway device sends the service type of the target service to the corresponding target container according to the network type. Then, the target container determines a routing policy corresponding to the service identifier according to the service routing information in the database, and sends it to the target driver, so that the gateway device sends the second service message for transmitting the service message to the receiving end according to the routing policy.

Optionally, referring to FIG. 3 , the first container may be a BRAS container in the user layer of the gateway device, and the second container may be a UPF container in the user layer of the gateway device.

Exemplarily, the preset service identifier of the first service message is the first packet with a granularity of 5-tuple flow. After the gateway device determines that the target service is a mobile network service, it sends a message to the UPF container through the ASIC-UPF-driver, and the UPF container generates a routing policy (including forwarding or discarding) with a 5-tuple flow granularity. ASIC-UPF-driver forwards the message.

Optionally, when the routing policy of the target service is acquired, the target driver may send a second service message for transmitting the target service according to the routing policy.

Exemplarily, the preset first service message is a follow-up packet of the mobile network data flow with a granularity of 5-tuple flow. After the gateway device determines that the target service is a mobile network service, it forwards and processes the data message through the ASIC-UPF-driver (that is, decapsulates the layer 2 and layer 3 message headers), obtains the routing policy, and directly processes the forwarding.

To sum up, during the process of service transmission, the service transmission device in the embodiment of the present application can read the pre-stored The service routing information determines the routing strategy corresponding to the service identifier, and then sends the second service message for transmitting the target service according to the routing strategy.
