In the above embodiment, if it is determined that the first packet does not comply with one of the MAC address filtering rule, the IP address filtering rule, and the Port filtering rule, the first packet is forwarded to the network protocol stack for processing. By the embodiment of the disclosure, under the condition that the first data packet does not conform to the forwarding rule, the network protocol stack performs data packaging, and normal data forwarding can still be ensured.
In one embodiment, as shown in fig. 5, a data forwarding method is provided, which is described by taking the service processor in fig. 1 as an example, and includes the following steps:
Wherein the address information includes at least one of a target MAC address, a target IP address, a target Port, and a target transport protocol.
The service processor acquires a target MAC address, a target IP address, a target Port and a target transmission protocol of a target terminal, and configures the target MAC address, the target IP address, the target Port and the target transmission protocol into the network coprocessor.
In a network coprocessor of a service processor, a forwarding rule list is preset, and a plurality of forwarding rules are stored in the forwarding rule list. After the service processor configures the target MAC address, the target IP address, the target Port and the target transmission protocol into the network coprocessor, the network coprocessor adds a new forwarding rule in the forwarding rule list according to the target MAC address, the target IP address, the target Port and the target transmission protocol.
The network coprocessor may maintain a list of forwarding rules, such as periodically cleaning the list of forwarding rules, deleting duplicate forwarding rules, ordering forwarding rules, and so forth. The embodiments of the present disclosure do not limit this.
After the service processor acquires the address information of the target terminal, the service processor can also send the address information to the media processor. And the media processor receives the address information and then performs address setting, so that when the media processor needs to feed back data to the service processor, the data to be transmitted can be processed according to the address setting to obtain a first data packet.
As shown in fig. 6, the process of performing, by the media processor, address setting according to the address information and processing the data to be transmitted according to the address setting to obtain the first data packet may include:
The routing information includes a corresponding relationship between the target IP address and a network port of the intranet switch. As shown in fig. 1, the intranet switch is disposed between the media processor and the service processor, and provides data exchange service for the media processor and the service processor.

After receiving the target IP address sent by the service processor, the media processor generates routing information according to the corresponding relation between the target IP address and the network port of the intranet switch, and adds the routing information into a host routing table.
Wherein, the arp information comprises the corresponding relation between the target MAC address and the target IP address.
An arp table is preset in the media processor. After receiving the target MAC address and the target IP address sent by the service processor, generating routing information according to the corresponding relation between the target MAC address and the target IP address, and adding the routing information into a host routing table.
When the media processor needs to feed back data to the service processor, the data to be transmitted can be packaged according to the reason information and the arp information, and a first data packet is obtained. In the header of the first packet, the destination IP address is a destination IP address, and the destination MAC address is a destination MAC address.
In one embodiment, the service processor periodically sends an arp reply packet to the media processor. Wherein, the arp reply packet is used for updating the MAC address table in the intranet switch.
In practical application, an intranet switch is provided with an MAC address table, the MAC address stored in the MAC address table is provided with an aging time period, and an expired MAC address can be cleared. If the MAC address is cleared, data forwarding failures may result. Therefore, the service processor sends an arp response packet to the media processor periodically, and when the arp response packet passes through the intranet switch, the intranet switch can learn the target MAC address of the target terminal according to the arp response packet, so that the MAC address table is updated, and data forwarding failure caused by the fact that the target MAC address is cleared is avoided.
As shown in fig. 7, a network coprocessor is disposed in the service processor, a coprocessor internal switch is disposed in the network coprocessor, and the coprocessor internal switch is provided with a plurality of forwarding ports. The media processor sends a first data packet to the service processor, and the service processor receives the first data packet sent by the media processor through a port 2 of the coprocessor internal switch.

If the first data packet is determined to conform to the forwarding rule, go to step 406; if it is determined that the first packet does not comply with the forwarding rule, step 408 is performed.
And step 406, if the first data packet is determined to meet the forwarding rule, performing address verification processing on the first data packet to obtain a second data packet.
As shown in fig. 7, an acceleration module may also be disposed in the service processor. After determining that the first data packet conforms to the forwarding rule, the network coprocessor sends the first data packet to the acceleration module, and the acceleration module determines whether to send the first data packet back to the network coprocessor.
And if the acceleration module determines to send the first data packet back to the network coprocessor, the network coprocessor modifies the source address, performs sum check and cyclic redundancy check on the first data packet to obtain a second data packet.
As shown in fig. 7, an application program is further installed in the service processor, and the acceleration module may generate first packet information according to the first data packet, send the first packet information to the application program, and notify the first packet information to the user by the application program. The notification manner may include presentation prompt information, playing prompt information, and the like, and the notification manner is not limited in the embodiment of the disclosure.
As shown in fig. 7, the network coprocessor transfers the second data packet obtained after the address check processing to port 0 of the coprocessor internal switch, and then the coprocessor internal switch sends the second data packet to the target terminal through port 1.
As shown in fig. 7, the service processor further includes a network card driver module and a network protocol stack. And if the filtering module of the network coprocessor determines that the first data packet does not conform to the forwarding rule, the first data packet is sent to the network card driving module, then the network card driving module sends the first data packet to the network protocol stack, and the network protocol stack repacks the first data packet to obtain a third data packet.
The network protocol stack may also generate second packet information from the third data packet, and then send the second packet information to the application program of the service processor, and the application program notifies the user of the second packet information.
